Our Precision Die Casting Services

If you need custom metal parts, we are a die casting service manufacturer that can help. High-pressure die casting of aluminum, magnesium and zinc, as well as investment casting of brass and all types of steel are now available. These are the two die casting capabilities we offer. 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.

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 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
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

Precision Machining FAQ

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.

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 We can help you.

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.

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.
When delivering prototypes to customers, we are often asked if we can provide small batch metal casting services. Because of this, we started looking for metal casting suppliers to meet these needs. Unfortunately, the search results are frustrating. Generally speaking, large foundry companies are not interested in small batch production, while small foundry companies cannot meet our quality requirements. This presents challenges, but we see it as a business opportunity: if we have a hard time finding the right companies for these projects, we know that overseas customers will have a hard time finding them. Two years later, we have successfully established relationships with a small number of medium casting partners who can meet our quality requirements and delivery time requirements. We are now able to offer high-pressure die casting of aluminum, magnesium and zinc, as well as investment casting of brass and all types of steel.
