Bi-Injection Molding Tech
3. The limit of Bi-injection or double injection molding
A. We know two different plastic material will have compatibility, the compatibility will be influence plastic intensity and plastic united. So when we choice two plastic for Bi-injection we need consider the compatibility between two plastic.
B.The compatibility between two plastic materials should be as little as well, if more will result in the two plastic cannot unite very well or difficult in molding. So we need choice reasonable compatibility in two kinds different plastic material, usually we used plastic collocation such as PP+TPE, ABS+AC, CA+EVA, HDPE+PA6, SAN+PVAC etc…on Bi-injection.
4. How dose bi-injection mould and machine work?
Bi-injection machine has two separate hopper and two barrel (in picture 1 and 2) for two different material or different colors plastic material injection, As for the mould ,it must be have two components inseparate cavity and core, A and B, for two different plastic prices. First, barrel 1 jet into cavity A, after holding, cooling and open mould, the semi-manufactures stay in core A, Then rotation system of Bi-injection machine will rotate mould by 180 degree. Then start second jet, two barrel jet at same time, after plastic of other component into cavity B, then two plastic will unite, finally, end product finish.
