Die Casting

What is Die Casting?

Die casting involves injecting metal into specialized molds, known as dies, under high pressure. It allows for the mass production of complex metal parts with exceptional dimensional accuracy, smooth surfaces, and consistent quality. It is particularly cost-effective for high-volume production runs, typically over 1,000 units, where reduced unit prices and shorter cycle times can offset the initial tooling and Non-Recurring Engineering (NRE) costs.

At Dingmetal, we specialize in OEM and ODM die casting services, delivering parts with intricate geometries and tight tolerances that are often difficult to achieve with other methods. With advanced manufacturing capabilities, we ensure many components require minimal post-processing or machining, saving time and cost while accelerating your path to business success.

Die Casting Methods at Dingmetal

• Our Die Casting Process

At Dingmetal, we specialize in cold chamber die casting, offering reliable solutions for high-melting-point metals. This method uses an external furnace to melt the metal. It involves manually pouring molten material into a cold shot chamber first and then injecting it into the mold under high pressure. This technique delivers excellent dimensional accuracy, strong mechanical properties, and longer equipment life, making it ideal for producing durable and structurally strong die casting parts with complex geometries.

• Available Materials

Zinc: Preferred for high-precision, high-tolerance components with excellent durability and castability.

Magnesium: The lightest structural metal, known for its strength-to-weight ratio, perfect for electronic and automotive applications.

Aluminum: Lightweight, corrosion-resistant, and ideal for aerospace and automotive parts where strength and minimal weight are equally important.

• Surface Finishing Options

As Cast: Functional finish with minimal post-processing, suitable for internal parts.

Polishing: Bright, reflective surfaces with reduced roughness, ideal for visual or decorative applications.

Sand Blasting: Consistent matte texture removes minor defects and prepares parts for coating or painting.

Anodizing: Improved resistance to corrosion and wear, available in various colors, primarily used for aluminum parts.

Powder Coating: Thick, durable, and colorful protective layers. Resistant to chipping and corrosion.

Plating: Adds a thin layer of metal (such as nickel or chrome) on the dicasting parts to enhance corrosion resistance, electrical conductivity, or surface appearance.

Chemical Film: Forms a protective layer on aluminum surfaces, improving corrosion resistance while maintaining conductivity. Ideal for electronic and aerospace applications.

Custom: We also manufacture die casting parts with custom finishes tailored to your application needs.
