Our Precision Die Casting Services

If you have needs of custom metal parts, RapidDirect is a die casting service manufacturer that can help. Since 2009, we’ve hold our engineering team and equipment to a high standard to continually deliver strong and durable parts and prototypes. To ensure legendary quality, we operate strict die casting process that ensures that your custom requirements are being met. These are two types of die casting capabilities we provide.

Hot Chamber Die Casting

Hot chamber die casting, also known as gooseneck casting, is a considerably quick process with a typical casting cycle only 15 to 20 minutes. It allows for high volume manufacturing of comparatively complex parts.

The process is ideal for zinc alloy, lean alloys, copper and other alloys with low melting point.

Cold Chamber Die Casting

Cold chamber die casting process is an very important procedure which helps reduce the amount of heat and solve the corrosion problem in machine’s plunder and related components.

The process is primarily used for alloys with high melting points, like aluminum, magnesium, some copper, and ferrous alloys.

Why Choose RapidDierct for Die Casting Parts

Alloys Used to Make Die Casting Parts

The non-ferrous metals that have low fusing temperature can be used for the die casting process, like aluminum, zinc, magnesium, lead, copper. But some uncommon and ferrous metals are also possible. The following will explain the properties of the commonly used die casting alloys that we use for the majority of parts.

Aluminum Alloys

Aluminum die casting alloy is lightweight structural metal mainly containing silicon, copper, magnesium, iron, manganese, and zinc.

It exhibits high thermal conductivity, electrical conductivity, cutting performance, and small linear shrinkage, making it has excellent casting performance and filling ability.

Moreover, aluminum alloys can maintain good mechanical properties under high or low temperatures because of their small density and high strength.

Commonly used Aluminum alloys:

A380, A360, A390. A413, ADC-12, ADC-1

More Details>>

Zinc Alloys

The main elements added to zinc die casting alloy are aluminum, copper and magnesium.

It provides a good surface finish without the need for secondary processing. Importantly, zinc alloy is more cost-effective and stronger than other comparable alloys.

Also, it has better fluidity and corrosion resistance so they are mainly used for die-casting meters, automotive parts housings, and other complex metal parts.

Commonly used Zinc alloys:

Zamak-2, Zamak-3, Zamak-5, Zamak-7, ZA-8, ZA-12, ZA-27

Magnesium Alloys

The main alloying elements of Magnesium die casting alloy are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium.

It has the advantages of high strength, low viscosity, good fluidity, great corrosion resistance and easy filling of complex cavities.

Magnesium alloy can be used for die casting of mold and thin-wall parts without thermal cracks.

Commonly used Magnesium alloys:

AZ91D, AM60B, AS41B

Die Casting Surface Finishes

Post-processing and finishing is the final step of precision die casting. Finishing can be applied to remove the surface defects of cast parts, enhance mechanical or chemical properties, and improve products’ cosmetic appearance. There are six types of die casting surface finish options.

As Cast	Regular casting finish obtained without the use of high-end tools or machinery. Like Zinc and Aluminum-Zinc parts can be as cast but still keep high corrosion resistance.	All materials	n/a	n/a	/
Powder Coating	Powder coating can be used to spray a free-flowing, dry powder to the zinc alloy and aluminum alloy die casting. Under strong electrostatic and high temperature, the powder will be uniformly adsorbed on the surface of the casting, forming a powder layer that can mask defects very well.	Aluminum, Stainless Steel, Steel	Black, any RAL code or Pantone number	Gloss or semi-gloss	Learn More>>
Bead Blasting	Bead Blasting is a process that sprays fine glass beads at high speed onto the surface of die casting parts using compressed air as the powder. The appearance or shape is changed, and the part obtains excellent cleaning and surface preparation for secondary finishing operations.

Anodizing	Mainly for aluminum alloy die casting. Anodizing utilizes electrochemical principles to generate a layer of Al2O3 (aluminum oxide) film on the surface of the parts. This decorative layer of oxide film provides high insulation and wear resistance.	Aluminum	Clear, black, grey, red, blue, gold	Smooth, matte finish	Learn More>>
Electro Phoresis	Used for aluminum alloy, zinc alloy die casting, etc. Electrophoresis applies metallic luster and an unlimited range of colors on the casting parts. It also can enhance the surface properties and corrosion resistance of metal alloy parts.	Aluminum, Zinc, Stainless Steel	Any	Metallic luster	/
Electroplating	Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.	Aluminum, Steel, Stainless Steel	n/a	Smooth, glossy finish	Learn More>>

Frequently Asked Questions

1. What are the steps of die casting process?

There are 5 steps to produce die casting products.

Step 1: Prepare mold. You need to heat the mold to a specific temperature and then spray the interiors of the mold with a refractory coating or lubricant.

Step 2: Inject material. After the solid metal alloy is melted into a liquid state, pour molten metal into the mold under a required pressure.

Step 3: Cool the metal. Once the molten metal is injected into the cavity, take sufficient time to let it harden so that it can form the shape of the mold.

Step 4: Unclamp the mold. Next, unclamp the mold carefully and take out the cast part.

Step 5: Trim the casting part. The last step is to trim sharp edges and excess material to make the desired component shape.

2. Which metal work best for die casting?

There are numbers of metals and alloys to choose for die casting project. The commonly used metals are zinc, aluminum and magnesium. Also, you can choose copper, brass, tin and lead for custom casting parts, However, it’s hard to determine the best metal because each metal alloy has its unique physical characteristics, advantages and disadvantages.

Therefore, if choosing the ideal metal bothers you, a custom die casting parts manufacturer RapidDirect can help you.

3. Is temperature important for metal die casting?

Yes, the temperature is a very significant factor in metal casting. The proper temperature can ensure the metal alloy is heated correctly and continuously flow into the mold. Otherwise, too high temperature can result in the damage of the mold; too low temperature can lead to shrinkage defects of the cast parts. So, it’s important to monitor the temperature.

4. Do die cast metals rust?

There is no fixed answer. The casting parts are commonly produced using aluminum, zinc and magnesium that are not mainly made from iron, which makes them corrosion resistant and hardly rust. But if you don’t protect your products in the right way for a long time, there is the possibility that they will rust.
