Die Casting

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. Most die castings are made from non-ferrous metals, specifically zinc, copper, aluminium, magnesium, lead, pewter, and tin-based alloys. The molds—also known as tools or dies—are created using steel and are specially designed for each project. This allows each component to be created with accuracy and repeatability. Aluminum, zinc, and magnesium are the most commonly used die casting alloys.

Die Cast Parts
Zinc, aluminum, and magnesium are the three main die casting alloys. They are normally non-ferrous and their mechanical properties vary greatly to fit almost every type of application a manufacturer may need.Different metals are available for casting. Your choice of materials may depend on cost, weight and performance. Here are some tips:

Materials Characteristics Applications
Zinc Alloy Die Casting High strength and hardness
Excellent electrical conductivity
High thermal conductivity
Low cost raw material
Ability to cold form, which eases joining
High quality finishing characteristics
Outstanding corrosion resistance
High dimensional accuracy and stability
Excellent thin wall capability
Full recyclability
Complex net-shaped zinc housings, with precise thin walls offer excellent electrical performance and shielding properties.
Our multi-slide die casting process and superior thin-wall capabilities make us the foremost supplier of zinc components for broad range of consumer electronic devices.
The castability of zinc, its wear resistance, and structural integrity make it perfect for the creation of the multi-faceted, highly complex shapes used in automotive safety and electronics industry.
Aluminum Alloy Die Casting High operating temperatures
Outstanding corrosion resistance
Lightweight
Very good strength and hardness
Good stiffness and strength-to-weight ratio
Excellent EMI and RFI shielding properties
Excellent thermal conductivity
High electrical conductivity
Good finishing characteristics
Full recyclability
Aluminum castings improve automotive fuel efficiency by contributing to weight saving requirements.
Aluminum is used in a broad range of networking and infrastructure equipment in the telecom and computing industries because RF filter boxes and housings require heat dissipation.
In handheld devices, aluminum castings provide EMI/RFI shielding, rigidity, and durability with minimal weight.
Because of aluminum’s excellent electrical performance and shielding properties, even in high-temperature environments, die cast aluminum is ideal for electronic connectors and housings.
Magnesium Alloy Die Casting High conductivity; electrical, and thermal
Withstands high operating temperatures
High dimensional accuracy and stability
Exceptional thin wall capability
Good environmental corrosion resistance
Good finishing characteristics
Full recyclability
There are many benefits to casting with magnesium. Not only is magnesium the lightest of all the structured materials but it has excellent stiffness and strength-to-weight ratios. Additionally, it has outstanding EMI and RFI shielding properties, perfect for connectors and electrical housings. It is also utilized for medical and laboratory equipment to provide protection against other interfering signals in a hospital room.

Die Casting Tolerances
We follow the standard general NADCA tolerances. However, if your requirements are very precise, then the precision tolerances standard can be followed once we have confirmed your designs.

The Challenges For Die Casting Aluminum Anodizing

Polishing of the castings may result in the “high” points of the metal surface being smoothed over resulting in “voids” in the metal that may be revealed in the anodizing process. You will have to experiment to see what polishing techniques produce the best finish after anodizing.With years of experience, We KinTec has studied out the best solution to anodizing die casting aluminum.

Die Casting Advantages

Die casting can have significant advantages over other manufacturing processes, which often lead to major cost savings, not only in the part price itself but also in the overall cost of production. Die casting is most suitable for casting medium sized parts with complex details.Die-casting is the largest casting technique that is used to manufacture consumer, commercial and industrial products include automobiles, toys, gears, parts of sink faucet, connector housing etc.

Benefits include:
Tighter tolerances
Variable wall thicknesses
Reduction in material scrap
Fewer steps from raw material to finished part
Fast production cycle times
Long tool life, especially for zinc and magnesium
