With years of expertise in this field , our pressure die casting service ensures consistent excellence whether you need a small quantity or several hundred castings. Pressure die casting is great for the automotive industry as well as electric, aerospace, kitchenware and hardware applications.

What is pressure die casting

Pressure die casting, also known as die casting, is a technique used to produce complex-shaped parts made from non-ferrous metals such as aluminum, zinc, and magnesium. It involves injecting molten metal into a reusable steel mold, known as a die, at high pressure and speed. The die is specifically designed to shape the metal into the desired form, with intricate details and excellent surface finish.

At HordRT, we offer a range of core services in pressure die casting to meet our customers' diverse needs.

Die Casting Materials

In fact, different metals can be used for casting. The materials you choose may depend on the cost, weight, and performance of parts. Here are some materials often used in Hord.

Aluminum Die Casting

Aluminum alloys are the most widely used in die casting.Aluminum alloy has light weight, high temperature resistance and good corrosion resistance, which is very useful in manufacturing various products. And we usually use the following aluminum alloys to make the parts:

A356.0
A360.0
A380.0
A383.0 (ADC12)
A413.0

Zinc Die Casting

Zinc is a versatile high-performance material.Its strength and stiffness allow it to produce parts with thinner walls and highly detailed features and maintain tight tolerances.

Magnesium Die Casting

Magnesium is another material commonly used in die casting. It is most suitable for complex castings because of its high tolerance and enhanced corrosion resistance.

Available Die Casting Finishes

Standard （As-Cast)

Zinc and aluminum zinc parts can be kept in the casting state and maintain reasonable corrosion resistance. Aluminum parts must be coated to achieve corrosion resistance.The cast parts are typically broken away from the casting sprue, leaving rough marks at the gate locations. Most castings will also have visible marks left by the ejector pins. The surface finish for as-cast zinc alloys is commonly 16-64 microinch Ra.

Bead Blasted

The part surface is a smooth, matte appearance.

Anodized (Type II Or Type III)

Aluminum is typically anodized. Type II anodizing creates a corrosion-resistant oxide finish. Although suppliers can anodize parts in different colors, the surface of a die cast part does not facilitate a cosmetic finish with anodizing. Type III is a thicker finish and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II. Anodized coatings are not electrically conductive.

Powder Coating

All die cast parts can be powder coated. This is a process where powdered paint is electrostatically sprayed onto a part, then baked in an oven. Powder coating creates a strong, wear- and corrosion-resistant layer that is more durable than standard wet painting methods. A wide variety of colors are available to create the desired aesthetic.

Wet Painting

All die cast parts can be wet painted in a wide variety of paint formulations and colors.

Plating

Die cast parts can be plated with electroless nickel, nickel, brass, tin, chrome, chromate, Teflon, silver and gold.

Chemical Film

Suppliers can apply a chromate conversion coat to protect aluminum from corrosion and improve the adhesion of paints and primers. Chemical film conversion coatings are electrically conductive.

Media Tumbled

Die cast materials are subjected to vibratory media tumbling to remove sharp edged and smooth surfaces.

Custom

We can also customize the surface treatment according to your needs.

The Benefits of Pressure Die Casting

Ability to produce high volumes of identical metal components, with high levels of accuracy
Cost-effective solution for the mass production of castings
Molten metal solidifies in a matter of seconds, or even milliseconds, for faster production
Can produce thousands or even millions of components before needing to be replaced.
Ideal for a wide range of applications
Great for highly complex and precise components
Suited to long production runs or where large volumes are needed
Close dimensional control and good surface finish
Castings with thin walls, and so lighter in weight
Most pressure die casting can be discreetly electroplated without any further processing

Common Applications

The versatility and high production potential of die casting make it suitable for various applications and industries. Small and medium-sized die-casting products with complex characteristics are usually very suitable for this process. For example, consumer and industrial products, auto parts, aerospace parts, and medical device parts.Die casting products is a great option when you need high-volume metal parts.

Pressure Die Casting FAQs

1. What is pressure die casting

Pressure die casting is the most effective and economical way to produce large quantities of metal parts with excellent surface finishing and dimensional accuracy. It is the process of making a high fidelity copy of a design by injecting molten metal into a customized steel mold.

2. Why should I use pressure die casting ?

It depends on the material, size and the geometry of the part. Generally, the tooling can be completed within 3 weeks. Some simple parts can be done within 3-7 days.

3. What materials are used in pressure die casting ?

Different materials can be used for pressure die casting. Aluminum, Zinc and Magnesium are most commonly used in the pressure die casting process.

4.How fast can I take my part ?

It depends on the geometry, size and quantity of parts. The typical lead time of tooling is about 2-3 weeks
