Material Compatibility

Magnesium
Magnesium alloy die casting is one example as it can make strong and lightweight parts, as well as some of the thinnest sections possible thanks to the melt's low viscosity.

Zinc
Zinc is used where strength isn't a priority as it's a more affordable material and easy to work with. It's also strong enough to make parts like enclosures and toys.

Copper
Copper isn't used much in die casting because the high temperature could induce more thermal shock and it could crack. If you're set on die-casting copper, you have to handle it very carefully and use a high-pressure process.

Pewter
Pewter is a soft alloy that combines other materials. It's mainly tin, but also has traces of copper and bismuth. It's used for decorative objects and is easy to die cast in low-pressure equipment.

Aluminum
Aluminum provides highly precise parts that range from moderately strong to very strong.

Application

Aerospace
The aerospace industry uses metal casting to manufacture aircraft engine components like housings and brackets using aluminum alloys (e.g., ADC12, A380) and magnesium alloys (e.g., AZ91D).

Automotive
The automotive industry uses the manufacturing process to make engine components like cylinder heads, transmission housings, blocks, and body parts such as wheel rims and door handles. Examples of automotive die casting materials used in the industry include aluminum alloys (e.g., ADC12, A380), zinc alloys (e.g., ZAMAK), and magnesium alloys (e.g., AZ91D).

Electronics
It is applicable in making electronics components such as connectors, heat sinks, and housings using aluminum alloys (e.g., ADC12, A380), zinc alloys (e.g., ZAMAK), and magnesium alloys (e.g., AZ91D). The manufacturing process can precisely make parts with complex details which are common to the electronics industry.

Consumer Products
Consumer products such as kitchen appliances, power tools, and other hardware are made using die casting process using aluminum, zinc, and tin alloy. Die casting offers high productivity, mass production, and cost-effectiveness, which are important in manufacturing these products.

Construction
The construction industry makes use of the die casting process in making hardware like hinges, window frames, and fixtures. The manufacturing process can produce parts with complex shapes hence it is important when functions and aesthetic appeal are important.

Process of Die Castings

Mold creation:

The process begins with creating a mold, also known as a die, typically made from hardened steel. This mold is designed to match the exact specifications of the part being produced and is engineered to withstand repeated high pressure and temperature cycles.

Injection process:

Once the mold is ready, molten metal is injected into the mold cavity at high pressure. This pressure ensures that the metal fills every crevice of the mold, capturing even the finest details of the design.

Cooling and ejection:

After the molten metal has been injected, it can cool and solidify within the mold. Once solidified, the mold is opened, and the newly formed part is ejected. The mold can then be closed and used again for the next cycle, making the process highly efficient for mass production.

Design and Engineering

Advanced Design Engineering. Advanced software tools such as EdgeCAM and AutoCAD allow us to work with complex prototypes, new or existing product redesigns. or reverse engineering methods to produce the desired product.
Comprehensive Tooling Approach. Our expertise helps us offer optimal material and tool matching, run sizing, and specification assessments to ensure designs meet all cost constraints and address project-specific needs.

Q: What are die castings?

A: Die castings are precision metal components produced by injecting molten metal into a steel mold under high pressure. This process allows for complex shapes, tight tolerances, and smooth surface finishes, suitable for high-volume production.

Q: What materials are commonly used in die casting?

A: Common die casting materials include aluminum alloys, zinc alloys, magnesium alloys, copper alloys, and lead/tin alloys. Aluminum and zinc are preferred for their strength-to-weight ratio, corrosion resistance, and cost-effectiveness.

Q: What industries use die cast parts?

A: Die castings are widely used in automotive, electronics, aerospace, industrial machinery, consumer appliances, telecommunications, renewable energy, and medical devices.

Q: What are the advantages of die casting over other metal forming processes?

A: Advantages include high production efficiency, excellent dimensional accuracy, complex geometry capability, consistent quality, smooth surface finish, minimal machining, and cost-effectiveness for large volumes.

Q: Can die casting parts be customized?

A: Yes. We provide custom die casting solutions based on 2D drawings or 3D CAD models. Our engineering team can optimize designs for manufacturability, weight reduction, and material performance.

Q: What tolerances can be achieved in die casting?

A: Typical tolerances range from ±0.05 mm to ±0.1 mm for standard features. Critical dimensions can be controlled more tightly using secondary machining or precision tooling.

Q: What surface finishes are available for die castings?

A: Available finishes include powder coating, anodizing (for aluminum), electroplating (nickel, chrome, zinc), polishing, painting, and passivation. Custom finishes can be tailored to client specifications.

Q: How is quality controlled in die casting production?

A: Quality is ensured through incoming material inspection, in-process monitoring, dimensional checks, X-ray or ultrasonic testing for porosity, and final inspection reports. Traceability can be provided upon request.

Q: What is the typical production volume for die castings?

A: Die casting is ideal for medium to high-volume production. Prototype and small batch production are possible but may require specialized tooling or low-volume dies.

Q: What is the minimum wall thickness for die cast parts?

A: Typical minimum wall thickness ranges from 0.8 mm to 3 mm depending on the material and design. Thin-wall die casting techniques allow for lighter components without compromising strength.

Q: Can die cast parts be machined or post-processed?

A: Yes. Secondary operations such as CNC machining, drilling, tapping, polishing, plating, heat treatment, and assembly can be applied to meet exact specifications.

Q: What design guidelines should be considered for die casting?

A: Design considerations include uniform wall thickness, proper draft angles, fillets at corners, ribbing for strength, and avoiding sharp transitions to prevent porosity and ensure smooth metal flow.

Q: What are the lead times for die casting projects?

A: Lead times depend on tooling, part complexity, and production volume. Prototype tooling typically takes 3–6 weeks, while full production runs may require 6–12 weeks from order confirmation.

Q: What certifications do die casting suppliers typically hold?

A: Suppliers often hold ISO 9001, IATF 16949, ISO 14001, and other industry-specific certifications. Certifications can be provided to meet customer requirements for automotive, aerospace, or medical sectors.
