Die Casting Service

Feature

Manufacturing process

1. Our materials are processed at high temperatures until melted;

2. Clean and lubricate both halves of the mold before closing the mold;

3. Prepare the casting mold with two steel molds, process the steel molds into the required shape and clamp them together through the die-casting machine;

4. Molten aluminum is then injected into the mold cavity under high pressure, allowing it to solidify.

5. The process of transferring molten metal to the die casting chamber before injection depends on whether a cold chamber die casting machine or a hot chamber die casting machine is used;

6. Allow the hot casting to cool and solidify. The molten metal fills the mold cavity and forms the shape required by the mold design.

Surface treatment type

Q: Is aluminum suitable for die casting?

A:  Yes, aluminum has high electrical and thermal conductivity and is resistant to corrosion. Its low density and good mechanical and thermal properties make it a good alloy for die casting.

Q: How strong is die-cast aluminum?

A: Die-cast aluminum, while not as strong as steel castings, is very strong and durable compared to sand, magnesium or zinc castings.

Q: Can steel be die cast?

A: Yes. However, it is a ferrous metal and contains iron, so it is not resistant to corrosion and is therefore not preferred.

Q: What are the disadvantages of die casting?

A: Die-casting is only suitable for high-volume production due to high equipment costs; secondly, changing part designs is time-consuming and expensive, so it is worth prototyping the part before proceeding with die-casting.

Q: What is the hot pressing process of die castings?

A: The hot pressing process is sometimes called the hot mold process. In this process, the plunger and chamber of the injection mechanism are immersed in a bath of molten metal in a metal furnace and used with low-melting point metals that will not chemically attack the immersed plunger assembly.

Q: What is the annealing treatment of die castings?

A: The process of heating the die casting to usually around 300°C, holding it for some time, and then cooling it to room temperature in the furnace is called annealing.

Q: Why use die castings?

A: Die castings are characterized by high dimensional accuracy and can mass produce thin-walled products with complex shapes.

Q: Why are die castings so expensive?

A: As a manufacturer, what I can tell you is that due to the nature of die casting, molds are subject to extremely harsh operating conditions during normal use.

Q: Can die castings prevent rust?

A: Aluminum, zinc, and magnesium is common metal materials used for die-cast metal parts. While every metal type is resistant to corrosion, there are different levels of rust resistance.

Q:  Is the surface finish of the die casting good?

A: Die cast parts are characterized by very good surface finish and dimensional capacity. Parts produced using the die casting process generally have thinner walls and smoother walls than parts produced using the sand casting process.
