Our Services

Support Both Low Volume And Large Volume Production

Investment Casting

Investment casting is a casting process involving pouring liquid metal into a ceramic mold. It is an ideal choice for producing precision steel parts with complex shapes.

Die Casting

Die casting is another casting method that involves injecting non-ferrous alloys into molds within die casting machines. A preferred process to produce light metal parts, such as aluminum, zinc, and more.

CNC Machining

CNC machining is a manufacturing process for machining parts on CNC machine tools. It is a good choice for metal parts requiring high precision, complex geometries, and high repeatability.

Metal Casting Types

With a variety of casting processes available, Dongguan Guochang Hardware Products Co., Ltd. offers different types of metal casting, mainly including zinc alloy casting, aluminum alloy casting, and other custom metal components according to customer requirements.

Aluminum Alloy Castings

  1. Low Density: The density of aluminum and its alloys is approximately 2.8 g/cm³—about one-third that of iron or copper.
  2. High Strength: Aluminum and its alloys offer high strength. The base strength can be enhanced through cold working, and some grades can be further strengthened through heat treatment.
  3. Excellent Electrical and Thermal Conductivity: Aluminum ranks just below silver, copper, and gold in terms of electrical and thermal conductivity.
  4. Good Corrosion Resistance: A dense and durable layer of aluminum oxide (Al₂O₃) naturally forms on the surface, protecting the metal from corrosion. Anodizing and coloring can further enhance this protection and improve casting performance or formability in deformed aluminum alloys.
  5. Easy to Process: With the addition of certain alloying elements, aluminum can achieve excellent casting properties (in casting aluminum alloys) or good workability (in wrought aluminum alloys).

Zinc Alloy Castings

  1. High specific gravity.
  2. Excellent casting properties—capable of die-casting complex and thin-walled precision parts with smooth surfaces.
  3. Suitable for surface treatments such as electroplating, spraying, and painting.
  4. During melting and die casting, it does not absorb iron, corrode molds, or stick to the die.
  5. Good mechanical properties and wear resistance at room temperature.
  6. Low melting point—melts at 385°C, making it easy to die-cast
