If, during your engineering phase, how you want to produce the product and what all that entails are already taken into account, you’ll be up against a production-ready product pretty soon. As you can read, there are many things that a designer must take into account when using this production technique. Well you can solve this problem with cooling, but a long cycle time will affect your cost. If your product is cooled too quickly it can cause your product to shrink dramatically, resulting in your plastic product to deform. If you have a fairly thick wall thickness, you can understand that you need more time to cool, than if you have a thin wall thickness. This is determined by the time the mold needs to cool. When you are going to injection mold a plastic product you also talk about cycle times. ![]() To get your plastic product out of the mold, you must always apply “unloading” to your design, otherwise you will never get your product out of the mold. Inside a mold are cooling channels, slides and ejection pins (to push a product out of the mold).īecause there are many different plastics, all with their specific properties, each type of plastic has its own effect in injection molding. In injection molding, plastic pellets, more commonly known as granules, are put into a hopper after which it is pressed into a mold/ die via a heated screw at high pressure. How does the injection molding process work? ![]()
