1. We are providing aluminum die casting services and zinc die casting services. Our material is aluminum alloy like ADC12, A380, A360 and zinc alloy like ZA-3, ZA-8. We have 13 sets die casting machines and the size ranges from 180Ton to 800Ton.

As a professional custom die casting company in China, Hongji have been doing custom die casting since 2003. We are experienced in tool design which will definitely influence the die casting process. The good design of the tool will make the production more easier and stable. We provide one-stop services including mold, casting, CNC machining, surface finish and assembly. We have our own workshop for mold making and CNC machining.

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a tool cavity. The tool is designed based on the product shape and is made from steel. After the tool is made. it is loaded on the die casting machines. Take aluminum die casting as an example, firstly the aluminum alloy ingot is melted under over 600 degree and then is given by robot to the casting machine. Then under high pressure, the tool separates which will get the raw part. This process can be run automatically by robot and X ray.  

Aluminum ingot is melted under high temperature and is given by robot to the inside tool on casting machine, then with high pressure, the tool separates, then you can get the raw parts between the tool.

zinc ingot is melted under high temperature and is given by robot to the inside tool on casting machine, then with high pressure, the tool separates, then you can get the raw parts between the tool.

Casting process is economic for massive production.

Different features of the product can be achieved at one time by casting process.

It is convenient to make changes on the tool, then you can apply this change on all the new production

Aluminum alloy: Good strength and cooling function.

Zinc alloy: Casting process is faster than aluminum material.
