Die Casting Capabilities Meeting Diverse Manufacturing Needs

At our die casting facility, we are equipped with automatic die casting machines of Hong Kong LK Group, a well-established company specializing in die casting machinery. Our state-of-the-art machinery ensures precision and efficiency in producing high-quality die-cast components tailored to meet a wide range of manufacturing needs.

Die Casting Process

Gravity Die Casting

In gravity die casting, the molten metal is poured into the mold by gravity. The process typically produces parts with tight tolerances and good surface finishes, suitable for high-volume production.

Our gravity die casting service is commonly used for:

  • reducing gear box housing
  • communication equipment housing
  • engine components (cylinder heads, pistons, and intake manifolds)
Pressure Die Casting

In pressure die casting, also known as high-pressure die casting (HPDC), the molten metal is forced into the die cavity at high pressure using a plunger, ensuring that the metal fills all the intricate details of the die.

Pressure die casting is often used for:

  • electric vehicle(EV) parts
  • motor accessories
  • components for outdoor lighting fixtures

Die Casting

  • High Production Rates: Die casting is highly efficient for large-scale production, offering high-speed casting of complex parts.
  • Dimensional Accuracy: Provides excellent dimensional accuracy and tight tolerances, making it suitable for precision components.
  • Surface Finish: Die casting produces parts with a smooth surface finish, reducing the need for additional machining.

Investment Casting

  • Precision and Detail: Investment casting allows for the production of intricate and highly detailed parts with excellent surface finishes.
  • Versatility: Well-suited for a wide range of metals, including ferrous and non-ferrous alloys.
  • Low Material Waste: The process generates minimal material waste as the mold is only a thin ceramic shell.

Sand Casting

  • Versatility: Well-suited for a wide range of metals and alloys, providing flexibility in material selection.
  • Low Cost: Initial tooling and setup costs are generally lower compared to investment and die casting, making it cost-effective for small to medium-sized production runs.
  • Large Parts: Suitable for casting large and heavy parts due to the adjustability of mold sizes.
