Why do injection molding and die-casting machines use different release agents

Firstly, it is necessary to understand the difference between injection mold release agents and die-casting mold release agents. The basic difference between injection molds and die-casting molds lies in the materials used. One is plastic, and the other is alloy. Therefore, die-casting molds need to withstand much higher pressure and temperature than plastic molds. The structure of the mold needs to be strengthened, and the feeding method, flow channel, and cooling design are all different.

Dynamic mold: fixed on the installation plate of the die-casting machine dynamic mold, the structure of the die-casting mold consists of a fixed mold: fixed on the installation plate of the die-casting machine fixed mold. There is a sprue connected to the nozzle or pressure chamber, and when the movable mold device plate moves to open and close the mold, it closes to form the mold cavity and casting system, and the liquid metal fills the mold cavity under high pressure; When opening the mold, the moving mold and the fixed mold are separated, and the casting is pushed by the pushing mechanism set on the moving mold.

The moving mold is installed on the moving template of the injection molding machine, and the injection mold consists of two parts: the moving mold and the fixed mold. The fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the dynamic and fixed molds are closed to form a pouring system and cavity. When opening the mold, the dynamic and fixed molds are separated to facilitate the removal of plastic products.

Environmental protection and economical use of release agents in aluminum die-casting are not contradictory. On the contrary, it is beneficial in the following processes, such as optimizing spray technology; Reduce the cost of waste liquid treatment; Enhance competitive advantage; Reduce the cost of mold release agents. An important positive side effect in the implementation of environmental planning for release agents is the increased awareness of the necessity for more precise determination and optimization of process parameters compared to before.
