Die casting

Springs and Shapes

In order to produce Higher strength parts for our customers, SunHui also full equipped die casting machines from 80T to 2000T.After die casting we also provide manufacturing services to the secondary process and surface treatment.


How does die-casting molding work?

Die casting at SunHui is a standard manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines - hot chamber machines (used for alloys with low melting temperatures, such as zinc) and cold chamber machines (used for alloys with high melting temperatures, such as aluminum). The differences between these machines will be detailed in the sections on equipment and tooling. However, in both machines, after the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting. The steps in this process are described in greater detail in the below flash.


Available materials for Die Casting

Aluminum Alloys

Aluminum is ideal for strong, lighweight yet complex geometries. It can also be highly polished.

Our alloys include ADC12,A380, ADC10 and ADC413.

Zinc Alloys

Zinc is the least expensive but is good for plating. Available alloys are Zinc #3 and #5.

Magnesium Alloys

Magnesium offers the best strength-to-weight ratio for higher performance applications.

We offer magnesium alloy AZ91D.

Surface Finishing for Die Casting

Painting

The process is sprayed with liquid paint. The appearance looks more beautiful after spraying various colors. At the same time, the life and service life of the product can be extended due to an extra layer of protection.  

Powder Coating

Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.

Anodizing

Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.

Elextroplating

Electroplating can be functional, decorative or corrosion-related. Many industries use the process, in which chrome-plating of steel automobile parts is common.
