How To Replace Different Raw Materials During injection Molding?

For general thermoplastic materials, the high temperature is easy to stick to the metal surface, while the low temperature is not easy to stick to the metal surface. The replacement operation is to use this property of the material, so that the material that wants to be replaced (want to be extruded) is stuck to the inner wall of the hot heating cylinder, and then the cold screw is supplied with the material with high viscosity (replacement material) to rotate to remove the material that wants to be extruded. These are our basic considerations, at this time, the temperature of the screw side should be kept as low as possible, so that the material that you want to replace is not

Sticking to the screw is the main thing.
