Basic knowledge of die casting mold

Die casting molds are generally divided into high pressure die casting and low pressure casting

The most important processing materials of die-casting molds are mainly aluminum alloys, magnesium alloys

And zinc alloys have also been made more in recent years

The main products of high-pressure die-casting are cylinder blocks of automobile engines/gearbox casings/integrated doors, etc.

Aluminum alloy wheels are the most common products of low pressure casting

Generally speaking, the failure form of die-casting molds is mainly early cracking, which has a relatively large relationship with the quality of the mold steel and the working conditions. At present, the quality of die-casting mold steels of well-known brands on the market is almost the same. The key lies in the heat treatment process. And the equipment, as well as the working conditions, whether to use the mold temperature machine

It has a great impact on the life of the mold.

Beilun in Ningbo is known as the hometown of die-casting molds. 40% of the world's large die-casting molds exceeding 2,000 tons come from Beilun
