1. Injection pressure
In the current dual color injection molding production, almost all injection machines have injection pressure based on the pressure applied to the plastic by the top of the plunger or screw (converted from oil pressure). The role of injection pressure in injection molding is to overcome the flow resistance of plastic from the barrel to the cavity, provide the rate of mold filling for the molten material, and compact the molten material.

2. Plasticizing pressure
In injection, the size of the plasticizing pressure needs to be changed according to the design of the screw, the requirements for product quality, and the type of plastic. If these conditions and the rotational speed of the screw remain unchanged, increasing the plasticizing pressure will strengthen the shear effect, which will increase the temperature of the melt, but will reduce the efficiency of plasticizing, increase countercurrent and leakage flow, and increase driving power.
In addition, increasing the plasticizing pressure often results in a uniform temperature of the melt, a uniform mixing of pigments, and the discharge of gases from the melt. In general operations, the determination of plasticizing pressure should be as low as possible while ensuring good product quality. The specific value varies depending on the type of plastic dual color mold used, but usually rarely exceeds 20 kilograms per square centimeter.
