2. Injection pressure:
Injection pressure is also one of the important process parameters for cold chamber die-casting machines. It determines the speed and pressure at which molten metal enters the mold cavity. The appropriate injection pressure can ensure sufficient filling of the casting and avoid problems such as defects and porosity. The selection of injection pressure should be adjusted based on factors such as casting shape, wall thickness, mold structure, and metal fluidity.
