Sole Guide about PLASTIC INJECTION MOLDS

SOLIDWORKS Technical Update

It’s time to update your skills for fastest growing Plastic industries. Here is a complete guide to learning everything about Plastic injection moulding. What is Plastic injection moulding? Plastic injection moulding is the process of producing plastic components & products of desired shape & size by injecting plastic granular or powder at a high pressure. Industries having plastic injection molding application- Plastic injection moulding is frequently using in industries producing plastic products of same shape & size in mass. It is a highly efficient technique to enhance industrial productivity in short time span. You can understand it’s area of application by looking plastic products in your surroundings at a glance. Construction of Mold- the mould specification based on the shape and size of the Plate. Core & Cavity plays the major role in injection moulding. Core as an internal geometry of the component and cavity as an external geometry of the component. While designing a mould we required complete specification of a product (as a shape and size) which can specify by 2D or 3D drawing and while manufacturing we require final shape and size of a plate which is base on the standard Mould base size. Machining of a mould executes on a conventional and CNC machine and after that polishing and trial or testing (T1, T2, T3) of a mould for production in injection moulding machine. Types of Injection Moulds- There is a variety of injection moulding process. Two-plate mould: Two plate mould (standard mould base) having one opening (Daylight) and one parting line. Three- plate mould: Three plate moulds having two daylight and parting line. It consists one extra plate that actuates as an ejection plate (stripper ejection plate) in which no requirement of no. of ejection pin and the plate assist the mould to eject the component. Split actuation mould: Split mould mainly used for undercut and having a wedge block in which the split will actuate and slider using for making undercut which is mainly near to the parting line and sometimes can’t provide side core to the middle of the component so we are using lifter. Hot runner mould: Hot runner system usually includes a heated manifold and a no. of heated nozzles. The main task of the manifold is to distribute the plastic entering the mould to the various nozzles which then meter it precisely to the injection point in the cavities. SOLIDWORKS PLASTIC Now let’s consider the role of SOLIDWORKS Plastic has a module that the part design capable of being injection moulded and specify a gate location and having a speciality that we can design a standard mould base in SOLIDWORKS and while designing a mould surfacing required for patching the hole and scaling required during cooling the plastic shrinks. To account for shrink factor scaling required. While designing a product for mould surfacing essential to create a complex product. In SOLIDWORKS Plastic we can simulate the injection moulding manufacturing process. One of the main point of SOLIDWORKS Plastic that having the ability to set a parameter as(filling time, cooling time, holding time )so that it’s convenient for the designer to specify their product to become productive.   The functionality within SOLIDWORKS Plastics allow the user to create a runner system specific to the needs of their design and multiple injection moulded parts can be created within the same cycle and from the same runner system. Right-click on the runner design option under the mesh node will bring up to the design tool. Choose polymer thousand of material models to come preloaded with properties as (Density, tensile strength, flexural strength) and are organised by material and supplier. SOLIDWORKS Plastic contributes to validate flawless products to meet your industrial productivity challenges.

Motion in SOLIDWORKS

SOLIDWORKS Technical Update

As now today’s era we are moving from 2d to 3d because the best part of 3d is that we can simulate the model in the virtual environment. In today’s market, there is a variety of tools that help you in testing your product, SOLIDWORKS Motion is one of them. Motion Studies are the graphical solution for Assembly Models. In this, we can simulate and animate the motion of a model according to our requirements. You can also use SOLIDWORKS mates to restrict your motion. Basically, we have three types of motion studies in SOLIDWORKS: SOLIDWORKS Motion (Animation): In this, we can only animate the motion of parts of an assembly like we can add a motor to drive the motion of one or more parts of an assembly and also prescribe the positions of assembly components at various times using set key points. This feature is available in the SOLIDWORKS Standard module. SOLIDWORKS Motion (Basic Motion): SOLIDWORKS Professional offers the advantage of Basic Motion over Animation is that in this we can approximately take the effects of Springs, Damper, Contact, collision, and gravity on assemblies, it also takes mass into account during calculation of motion, and the best part of it is that the computation of basic motion is relatively fast. SOLIDWORKS Motion (Motion Analysis): In this, we can accurately simulate and analyze the effects of motion elements (including forces, spring, dampers, and friction) on an assembly. Motion Analysis uses computationally strong kinematic solvers and accounts for material properties as well as mass and inertia in the computations. You can also use Motion Analysis to plot simulation results for further analysis. In SOLIDWORKS Premium you can see time-based as well as event-based motion effects and make further analysis to plot simulation results. In addition, you can also utilize the Motion Manager toolbar – Change viewpoints. Display properties. Create distributable, presentation-worthy animations depicting the motion of an assembly.   It’s a personal suggestion that starts using all these testing tools of SolidWorks because many of our customers including me take the advantage of these tools which directly reflects on our design. So, at last, I would like to conclude that these tools help us a lot in designing and also reduce our prototyping.   Tech Savvy Engineers Pvt. Ltd.

How to Manage 3D PDF Attachments Using SOLIDWORKS

Business, SOLIDWORKS Technical Update, World News

SOLIDWORKS MBD can help you attach multiple documents before publishing a 3D PDF To collaborate with suppliers, engineers often need to send technical documents such as CAD models, neutral STEP files, 2D drawings, QA provisions, and internal standards. This list goes on, and each document in this long list may generate its own revisions over time. In order to consolidate the fragmented documents, the U.S. Military Standard 31000A: 2013 recommended a concept called Technical Data Package (TDP). The gist is to bundle multiple technical documents together into one package to avoid disorganized individual files, in a way similar to shipping containers or closet organizers. Even if you don’t have to comply with the military standard, this practice still makes sense. One packaging tool presented in the standard is 3D PDF. It allows multiple attachments as shown in Figure 1. You may download the 3D PDF at the SOLIDWORKS MBD forum and check it out in Adobe Reader. Please don’t open a 3D PDF in your browser because the browser would disable the 3D content.   You may notice four component documents are attached on the left. You may double-click to view them separately or save them locally. SOLIDWORKS MBD can help you attach multiple documents before publishing a 3D PDF. However, depending on your Adobe Reader settings, sometimes you may run into this dialog as shown in Figure 2 when trying to open a SOLIDWORKS part from the attachment list. It says Acrobat cannot open this file attachment because your PDF file attachment settings do not allow this file type to be opened. The reason is that Adobe Reader version 11 and later added a layer of protection to avoid any malware. If you trust the data you received in a 3D PDF, you can adjust the PDF file attachment settings under the menu Edit, then Preference, and then Trust Manager, as shown in Figure 3. After checking this box, you will see a prompted dialog upon double clicking on an attachment as shown in Figure 4. In this way you can decide on a case-by-case basis whether you want to open a file. You can also decide to always or never allow file of this type to avoid making the same duplicated selections going forward. I hope this blog post is helpful for your collaboration with suppliers using 3D PDF as a technical data package. If you have any comments or questions, please feel free to leave them in the comments area below.

Brewing with Electricity: The SOLIDWORKS Brewery: Lautering and Sparging

SOLIDWORKS Technical Update

Up to this point, our grains have been soaking in water that has been set to the perfect temperature in order for us to extract as much sugar from the grain as possible. With the slim chance that we left some sugar in with the grain, we need to take a few additional steps – which are known as lautering and sparging. In large scale operations that you might see at one of the many breweries around North America, mashing, lautering, and sparging are typically performed in separate tanks. But due to the fact that this equipment is for personal use (and has been set up in Earl’s living room), we perform these steps in the same kettle. It’s all about efficiency. This same concept applies when designing our schematics. One particular feature of SOLIDWORKS Electrical can help improve our efficiency AND our effectiveness during the design process. Project Macros is that feature and it can be extremely powerful. It’s kind of like the old copy-paste option, but way smarter and way faster. We can take a symbol with associated part information and save it off for future use within our current project or in any other project we so choose. We can also copy multiple symbols and all the wires connecting those symbols. To make it even better, we can copy entire sheets or multiple sheets and create a macro out of them as well. As I mentioned already, (and as you can probably tell) Project Macros is my favorite feature in the software. We can even take our macros to the next level by incorporating them with the Excel Automation tool as well as the PLC configuration tool – both of which can help us make our designs even faster. So be sure to check out Episode 4 in our “Brewing with Electricity” mini-series where we conduct the lauter and sparge phase to increase the sugar in our wort and discuss the various methods of symbol creation within SOLIDWORKS Electrical.

SOLIDWORKS Plastics At The Beach

SOLIDWORKS Technical Update

By using SOLIDWORKS Plastics we can simulate the injection molding manufacturing process Well summer is just around the corner and my family is chomping at the bit to get down to the beach. Last weekend I cleared out the garage and dug out all our children’s beach gear, buckets, spades, and alike. Which got me thinking, could I a mechanical engineer with minimal plastics training, design a new sandcastle bucket that looks right and can be successfully manufactured? In order to keep the cost down, I decided that my sandcastle will be manufactured using the injection molding process. Creating the geometry in SOLIDWORKS is a breeze, a few extrudes, some patterns, fillets, a shell feature and I am good to go. Lastly, by running a draft analysis I know that the geometry can be ejected from the mold. But as every engineer knows, the geometry is only half the story. The big questions are, can this part design be injection molded, and is the resulting part acceptable? By using SOLIDWORKS Plastics we can simulate the injection molding manufacturing process to ensure that not only is the part design moldable, and that the resulting part is fit for sale. The first set of questions I need answered by SOLIDWORKS Plastics are “Is my part design capable of being injection molded, and where do I place my gate location?”. The least expensive form of injection molding uses a cold runner system with the gate located on the parting line. So I now have a new question, “Do I gate from the short side of the sandcastle, or gate from the tall side”? Doing this by trial and error after machining the mold is not an acceptable option, as it is far too expensive of a test procedure. By using SOLIDWORKS Plastics, I can run multiple analyses as my testing method and all it costs me is CPU time and not much else after that. My first test has the gate located on the short side, shown by the green arrow in the image below. SOLIDWORKS Plastics reports a Fill Time of 9.5 seconds and required Injection Pressure of 74.2 MPa. This part design has a large part volume, so the lengthy fill time is reasonable and the injection pressure is well within most machine maximum injection pressure capabilities of 200 MPa. My first question regarding the moldability has been answered. Yes, my part design can be molded. Although, at first glance the results look good, there is an issue with my gate location on the short side. SOLIDWORKS Plastics predicts a large and visible Weld Line on the tall side of the part, shown below by the red arrows. The reduction in structural integrity caused by the Weld Line is not my concern, as this is a beach toy and will not be supporting extensive loads. What does concern me is our company primarily uses metallic-flake colorant in our plastic materials, and metallic flake noticeably gathers along Weld Lines and is an aesthetic blemish on the molded part surface. In my second analysis, I gated the part from the tall side of the sandcastle. The Fill Time and Injection pressures are similar, and now the Weld Line results show two weld lines in less noticeable locations. They are much smaller than original weld line and are spaced further apart. So gating from the tall side is my best option. I now have the gate location squared away, what kind of runner design and mold design should I use for production? A quick chat with a friend suggests a four cavity layout with an “H-Type” runner system would be a good starting point. Once again using SOLIDWORKS Plastics, I can simulate the manufacturing process so I can validate the moldability of my part design. Now let’s make sure my “H-Type” runner design is my best option before cutting any metal and incurring unnecessary expenses. Due to the height of the sandcastle design, using a sprue inlet diameter of 5.0 mm and a standard sprue draft angle of 3.0 degrees results in a sprue outlet diameter of 31 millimeters. The 31 mm diameter runner will take about seven minutes to cool down sufficiently to eject from the mold. Even I know a seven minute cycle time is no good for production. Once again SOLIDWORKS Plastics is guiding me towards a better manufacturing process for my part design. I make the decision to not use a parting line runner system for this mold layout. The first step to reduce the sprue height is to gate from the top of the sandcastle by using a “three plate, cold drop, center gate”. This is a similar approach to how 5 gallon buckets are injection molded, except those use a much more expensive hot runner system. The results from this center gate analysis shows that that there are no substantial weld lines to be seen when gated from the top face. Since the center gate on the top face is the optimal gate location, this will be the runner design used to injection mold the highest quality part, using the most cost effective design. SOLIDWORKS Plastics In plastic part design, the geometry is only half the story. SOLIDWORKS Plastics should be used throughout your design process to validate your part design, runner design, and mold design saving you both time and money.

Bicycle

The Whirlwind Engineering History of the Bicycle

SOLIDWORKS Technical Update

Bicycle History- Stridewalkers, Boneshakers, Penny Farthings. The bicycle has been privy to some curious iterations. Fetch your helmet, here’s a whistle-stop tour of the bike’s 220-year history. Who needs nuclear power when you’ve got a bicycle? That’s what the nation’s listeners of UK Radio 4 program You & Yours decreed in 2005 when they voted the bicycle as the most significant technological innovation since 1800. In winning the poll – emphatically – the humble bike also batted away competition from the computer, radio, the internet, communications satellites, internal combustion engines and the germ theory of infection. Not bad. But what’s so special about two wheels, a frame, and a saddle? Well, it turns out there’s rather more to it than that. So much so that today’s performance bikes are as much the work of F1 engineers as bike manufacturers. Yep, the bike’s wheels have rolled an awfully long way since the clunky wooden specimens of the eighteenth century. Today the world’s one billion bikes represent the most efficient vehicle the world has ever seen. Behold its history. 1817: The world’s first bike? Step forward German inventor Karl Drais, who in 1817 patented the design for his Laufmaschine (translation: running machine). Riders straddled a wooden frame and – in the absence of pedals and chain propulsion – pushed their feet along the ground to get the wheels moving. Hence the distinctly sci-fi-sounding nickname: Stridewalker. 1839: The birth of pedal power Kirkpatrick MacMillan, a Scottish blacksmith, makes what would become the most influential addition to the story of the bicycle: a mechanical crank-drive system attached to the rear wheel. Hello pedals, goodbye scuffed shoe soles. 1863: The Boneshaker becomes the world’s first mass-produced bicycle Building on MacMillan’s crank-drive innovation, Pierre Michaux (another blacksmith) and his son Ernest developed the world’s first mass-produced bicycle in 1863. It was called the velocipede and had flanged wheels that endowed it with the unique ability to ride along rail tracks. Hmm. Back on the cobbled streets of the nineteenth century, the wooden-rimmed wheels were particularly unforgiving – earning Michaux’s bicycle the nickname ‘Boneshaker’. 1870: The birth of the penny-farthing It might have looked ridiculous, but the Penny-Farthing was built to serve a very practical need: the need for speed. Without gearing, the only way to increase bicycle speed was to increase the size of the wheel attached to the pedals – and the enhanced availability of steel meant large wheels were a simple engineering challenge. Unfortunately, penny-farthings were incredibly difficult to mount, much less ride and became the preserve of the brave, the skilful and the foolish. 1879: The birth of modern bicycles During the late 1870s, a number of inventors developed an alternative to the penny-farthing, marketed as the safety bicycle for obvious reasons. With a chain drive that allowed the rider to sit at the centre of the frame, a height that made it easy for riders to reach the ground and wheels that were broadly the same size, the safety bicycle fuelled the surge of bicycle popularity in the 1890s and the birth of companies such as Raleigh and Schwinn. The same design is used to this day. Yep, for the last 140 years all we’ve been doing is tweaking a design classic. 1888: Watch where you tread Scottish veterinary surgeon and inventor John Dunlop are the first to add pneumatic tyres to a bike while successfully attempting to make his son’s tricycle safer. He then brought his innovation to cycle racing and it was quickly adopted. The following fifty years was a time of major innovation in terms of gearing, brakes and derailleurs. 1940: Changing gear gets simple Italian bicycle component manufacturer par excellence Campagnolo invented a derailleur called the Cambio Corsa. It’s revolutionary. Instead of stopping and flipping their rear wheel to change gear, riders can flick a rod located above the rear wheel. 1986: The clamour for carbon The 1980s dawned an era of serious engineering innovation for bikes. Suddenly the everyday consumer could purchase BMXs, mountain bikes, road bikes, commuter bikes, elite racing bikes, tandems and more. One of the most major innovations of the 80s comes when manufacturer Look produced a racing bike with a carbon fibre frame. Ridden by Greg LeMond, Look’s KG86 wins the 1986 Tour de France. 1990: The UCI defines what a bicycle is UCI, the governing body of cycling, defines what a bicycle is. All race bikes must abide by these parameters and bicycle engineers everywhere have a strict set of limitations within which to innovate. What’s the future of bikes? The UCI parameters mean that the basic design of bicycles for competitive races isn’t going to change anytime soon. That doesn’t mean visionaries can’t have their fun with concept bikes and commuter bikes. Oh and lest we forget the revolutionary trikes that Van Raam have developed in SOLIDWORKS for those with mobility issues and their carers.

How Does Home Licensing for SOLIDWORKS Work?

SOLIDWORKS Technical Update

SOLIDWORKS users have long enjoyed the ability to use their software from both their home/mobile and work offices. How is this accomplished without running afoul of the EULA (End User License Agreement), which only permits one license enabled on any one computer at any one time? In our previous two blog posts, we examined perpetual licenses (Standalone and SNL) and term licenses. Let’s first look at standalone licenses. Standalone licenses are intended for an individual user of SOLIDWORKS or a related product. It uses an activation process to enable your license to operate after installation. Once the software is activated on a computer, it remains permanently enabled until such time as you choose to deactivate it. If you would like to run SOLIDWORKS on another computer, you must first deactivate (using “Help – Deactivate Licenses”) the computer holding your SOLIDWORKS_License. The Activate/Deactivate function inside the software allows you to install SOLIDWORKS on as many computers as you wish – ensuring only one computer is operational with SOLIDWORKS at any one time SOLIDWORKS Standalone / perpetual licenses with subscription service for an individual user as displayed inside the application. If you would like to run SOLIDWORKS on another computer, you must first deactivate (using “Help – Deactivate Licenses”) the computer holding your SOLIDWORKS license. The Activate/Deactivate function inside the software allows you to install SOLIDWORKS on as many computers as you wish – ensuring only one computer is operational with SOLIDWORKS at any one time. Standalone licenses are activated/deactivated under the Help menu in SOLIDWORKS allowing you to run the software on multiple computers. Users can borrow or hold a license/s for up to 30 days. SNL license usage showing five total licenses, three of which are in-use, one license borrowed, and one license free. SNL, or network licenses (sometimes referred to as “floating” licenses), also uses an activation process but only for the server, which monitors concurrent license usage. The individual clients running SOLIDWORKS or a related product or add-in retrieve a license each time the software is started, and return the license each time it is closed so that another user can use it. SNL clients can “borrow” a license temporarily for up to 30 days, after which time if the license has not been returned, the server will automatically do so. The status of license usage can be checked at any time. Any borrowed licenses will also display in this pane. Home/mobile use is of course possible for term licenses as well. Term licenses, from an installation and entitlement perspective, behave in the same exact manner as standalone licenses, i.e., license access is granted through the activate/deactivate process. If a user would like to run a term license on another computer, the license must first be freed up using Deactivate license under the Help menu as described earlier. This concludes our blog series about licensing with SOLIDWORKS. If you would like to see other articles related to this topic, please comment below and we’ll consider it in a future topic.

MIT Students Take Innovative New Product from Dorm Room to Market in Record Time

SOLIDWORKS Technical Update

SOLIDWORKS – MIT Students Take Innovative New Product Any college student will tell you that coffee is often a key ingredient to surviving those stressful days of college when hours of slumber are in short supply. When cost-conscious college students splurge on expensive to-go coffee from places like Starbucks or Dunkin Donuts, they want to savor every drop of that hot, precious beverage. Get sidetracked for a minute, however, and that hot beverage is suddenly not so hot, literally. Two recent MIT graduates created the Coffee Cookie to extend the amount of time your coffee stays warm. Victoria Gregory and Gabriel Alba are two Mechanical Engineering students who just recently graduated from MIT. Conceived by the duo during an exercise in a Product Engineering class, the Coffee Cookie is a small circular device that attaches to the bottom of a disposable coffee cup and heats the liquid within up to 90 degrees Celsius, and resembles…you guess it, a cookie. Powered by a rechargeable battery, the device can be recharged for daily reuse. After conducting some initial research via an online survey of 300 people, Gregory and Alba determined that respondents—especially millennials—are likely to pitch takeout coffee once it loses heat, typically tossing the final third of the cup. The research results indicated that the device would not need as big of a battery as initially thought, making their burgeoning idea doable.   Bringing an idea to life Hatching an idea for a new product is just the first of many arduous steps for startups. Like any entrepreneurs, Gregory and Alba had to figure out how to bring their idea to life. During the pair’s sophomore year, they both learned how to use SOLIDWORKS for a class project to design a robot. While Gabriel had previous experience using a suite of Autodesk products during high school, he felt more comfortable using SOLIDWORKS. “SOLIDWORKS just clicks more with the way I think and the way I design products,” says Alba. The pair pitched their idea to the board of the Sandbox Innovation Fund Program at MIT where they were awarded $10,000 to seed their startup. Over winter break from school, the two embarked on creating prototypes of the device. Making use of both dorm rooms and student maker spaces, the two put in long hours over those four weeks, sometimes up to 24 hours straight. In a single day, they designed and 3D printed the device so they would have physical proof of concept. While the first one lacked the sophistication of typical prototypes—part of which was held together with hot glue—the pair soldiered on to creating several more prototypes that would fit a variety of disposable cups. With a very limited budget and a tight timeframe with which to work, the students knew that any mistakes made along the way could jeopardize the project. To prevent that from happening, the two unleashed the power of SOLIDWORKS Plastics Simulation software to simulate the plastic flow into the plastic molds that would be used to create the plastic casing for the device’s battery.   SOLIDWORKS Plastics “SOLIDWORKS Plastics would tell us what size to make the gates and how to set up our parameters,” says Gregory. “An experienced mold maker could probably make an educated guess but we wouldn’t know. If we had a part short shot, we would have had to re-make the whole model so using the software saved us a lot of time over doing it from scratch.” To create the printed circuit board (PCB), they used CircuitWorks so they could closely coordinate the design of both the mechanical and electrical components of the device, again mindful of the impact any error would have on their short design cycle. “SOLIDWORKS is such a great learning tool and saved us so much time to do this project while maintaining a full class load at MIT,” says Alba. “SOLIDWORKS has been our best friend for this project.” Once the prototype was complete, the pair decided to ramp up to 1,000 units. They ordered 1,000 batteries from China and spent their time since graduating from MIT in May assembling the units. Recently Gregory and Alba moved to New York City to explore possible avenues through which they can sell their Coffee Cookies to consumers, where they will target mothers, college students, young professionals, and busy executives who must get their caffeine fix on the run but still like it hot.  

CONTOUR

Selecting multiple CONTOUR is no more hassle with SOLIDWORKS 2017

SOLIDWORKS Technical Update

Selecting multiple CONTOUR is no more hassle Previously multiple selections of sketch entities for extruding or removing any area was a big hassle and it was leading to a great loss of time and confusion. Sometimes wrong selection creates uneven extrudes and leads to failure in improper part development. Now with just a single press on an ALT key, you can select multiple sketch entities and get a ride from the uneven selection. SOLIDWORKS 2017 has a capability that the context menu that appears after selecting the two contours can be customized to add the Cut-Extrude command to it. To customize it RMB on it when it’s displayed. The same applies to the context menu that appears when clicking on a shaded contour region.
