Die Casting Method

Hot-Chamber-Die-Casting

Hot Chamber Die Casting

Melting point < 450 ℃
Applicable materials: Zinc
The die casting chamber and die casting punch of the machine are immersed in the molten metal, which is then directly injected into the mold through the gooseneck tube. The molten metal is contained within an internal closed channel to minimizing contact with the outside environment, thereby reducing oxidation loss, and ensuring the purity of molten metal. Its simple structure allows it to be used in combination with an automated robotic arm to achieve highly automated production, an integrated smelting and injection system, and an extremely short molding cycle (10-30 s).
Cold-Chamber-Die-Casting

Cold Chamber Die Casting

Melting point > 600 ℃
Applicable materials: Aluminum, Magnesium
Cold chamber die casting involves melting metal in a separate furnace, then injecting the liquid metal into the injection chamber using a scoop, and finally, forcing the molten metal into the mold through the injection rod. The injection pressure can range from 70 to 150 MPa, which is suitable for processing large and complex parts on automobiles and motorcycles.

Aluminum

Aluminum is a lightweight, corrosion-resistant metal known for its excellent strength-to-weight ratio and thermal conductivity. It is widely used in electrical housings, heat sinks, enclosures, and structural components. Aluminum is easy to machine, weld, and extrude, making it ideal for applications in electronics, transportation, and industrial equipment where durability and efficiency are essential.

  • About the Mold (2)
  • About the Mold (1)
We provide the following three flexible solutions for mold costs:
1. Based on the actual requirements of the project's early preparation, you first bear the mold R&D, design and production costs to lay the foundation for the smooth progress of the project.
2. LVMA will negotiate with you on a reasonable way to share the development costs based on the actual purchase volume. This will ensure that the cost structure of both parties is more flexible and optimised.
3. Formulate a purchase volume agreement. Upon the achievement of the cooperation goals agreed upon by both parties, the mold fees collected in the early stage will be fully refunded according to the agreement.

Advantages of Die Casting

Smooth Surface

After die casting, the surface is relatively smooth and can usually reach Ra1.6-3.2μm after processing.

High Production Efficiency

The production efficiency of cold chamber die casting is 80 pieces/hour, and the production efficiency of hot chamber die casting can reach 1200 pieces/hour

Material Utilization

Through high-pressure injection molding, no secondary processing is required, and waste materials can be recycled, with a material utilization rate of more than 90%

Scale Benefits

The service life of the casting mold is tens of thousands of times, and batch processing can spread the mold cost.
