WJ Die Mold offers Insert Molding Services as an add-on to the plastic injection molding process. There is one direct difference between the two processes; the plastic injection molding process only uses plastic material in order to create a product. On the other hand, the Insert Molding process includes other types of plastic and/or metals in order to create a more advanced product. There are thousands of uses for Insert Molding manufacturing.
The Insert Molding Process
The Insert Molding process starts off by either inserting the metal inserts before the custom injection molding process, or they can be inserted during the custom injection molding process. If the inserts are chosen to be inserted during the plastic injection molding process, an Insert Molding process operator or a robotic arm will load them. If chosen to insert the metal inserts after the plastic injection molding operation, the same robotic arm or Insert Molding process operator will load them after the plastic injection molding process is complete. Usually, Insert Molding takes place after the custom injection molding process. This procedure ideally reduces insertion costs, which can save our customers substantial costs on custom insert molding projects. (more…)
Many industries rely on Plastic Injection Molding to create most of today’s products and/or parts of products which are sold on the market.
The Plastic Injection Molding process
The process starts by having grains of plastic fed into a heated barrel from a hopper. Actually, the granular plastic is forced into the heated barrel by gravity. When the plastic granules make their way into the heated barrel, a screw-type plunger slowly moves them forward into a heated chamber. The chamber melts the plastic. As the same plunger advances, it forces the melted plastic through a nozzle. This nozzle rests against the mold. The melted plastic then enters through a runner and gate system to fill the mold cavity. After entering the mold cavity, the plastic solidifies. The plastic usually solidifies just as soon as the whole entire mold is filled, because the mold remains cold throughout the whole Plastic Injection Molding process. (more…)
