Our Precision Die Casting Services

If you have needs of custom metal parts, AL Aluminum 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.

Die Casting Technical Standards

With precision CNC machining services, AL Aluminum is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements on your drawing.

Most frequent questions and answers

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.

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.
