Gas-assisted injection (modeling) molding, also known as gas injection (shot molding) molding, is a new injection molding process. It is one of the most important developments in the injection molding industry since the advent of reciprocating screw injection machines. Gas-assisted injection molding is an extension of injection molding. It is developed on the basis of injection molding technology ...

Double Injection Mold, also known as two material molding, 2 shot molding or 2K molding, is a manufacturing process used to produce complicated molded parts from two different materials. Two kinds of plastic materials are injected on the same injection machine, and they are formed twice, but the product is only molded out at once. This injection molding is usually completed by one mold and require...

Insufficient injection is also called short shot. Short shot is the phenomenon of partly incomplete at the end of the material flow, or a part of the cavity filled with dissatisfaction, especially the thin wall area or the end area of the the runner when injection molding. When the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavi...

The short shot checkpoints As mentioned that, when the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavity, it is called the short shot injection molding. We analyse the reasons of short shot. So today let’s discuss how to improve the insufficient injection. Here lists short shot checkpoints: 1) Improper control of process conditi...

Double Injection Mold is also called Two Color Mold. That's two different materials or two color materials injected in one injection machine, injected by twice, but the product only comes out one shot from the mold. This mold technology is called double material injection, usually finished by one set mold, and it needs special two color injection molding machine to produce the products. Double inj...

When we finish a plastic injection mold, we need make mold testing. Sometimes you may find the product comes out with short shot. Today we will talk about how to avoid short shot.          A Increase the temperature      B Increase the pressure           C Extend the shoting time      D Check and add more air vent...
