The die casting includes high pressure die casting(HPDC), low pressure dies casting(LPDC), Squeeze casting, gravity(GDC), an EMP is specialized in high pressure die casting, which is most commonly used for automotive, telecommunication, industrial etc.
The die-casting machine is generally divided into cold chamber die-casting machines and hot-chamber die-casting machines.
The cold chamber die-casting machine is divided into the horizontal die-casting machine and vertical die-casting machine according to its chamber structure and layout.
