Precision Casting
for Efficient Manufacturing

Die Casting Expertise

Explore the versatility of die casting processes and equipment to meet diverse project requirements.

High-Pressure Die Casting (HPDC)

Molten metal is injected into steel molds at high speed and pressure, producing complex parts with high precision and smooth finishes.

Low-Pressure Dic Casting (LPDC）

Molten metal is pushed into the mold from below using low pressure, minimizing turbulence and porosity, ideal for structural components.

Gravity Casting(GC)

etal flows into a permanent mold by gravity alone, offering stable quality and good mechanical strength for medium-sized parts.

Hot&Cold-Chamber Casting

Both inject molten metal into molds under pressure—hot-chamber draws directly from the furnace, while cold-chamber requires external ladling for high-melting-point alloys.

Casting FAQs

Have questions about Die-Casting? We’ve compiled a list of frequently asked questions to help you understand our processes better.

1. What is your casting process?

Our casting process involves several steps:

Pattern Making: Creating a model of the part to be cast.
Mold Preparation: Preparing the mold material, often sand or metal.
Pouring: Pouring molten metal into the mold.
Cooling: Allowing the metal to solidify.
Post-Processing: Removing the casting from the mold and performing any necessary finishing.

2. Can you handle complex or custom designs?

Yes, we specialize in custom metal casting, creating complex or custom-designed cast parts tailored to your exact specifications. Our experienced team and advanced casting techniques allow us to meet the unique needs of each project—no matter how intricate the design.

3. What is the maximum size or weight of parts you can cast?

Our casting capabilities allow us to handle parts up to 1000x600x300mm and 25kg, depending on the material and process used.

4. What is your minimum order quantity (MOQ) for casting?

Our minimum order quantity for casting is typically 2000 units, depending on the part complexity and material. For larger quantities, we can offer more competitive pricing.

5. How do you ensure the quality of cast parts?

A: We use advanced quality control methods, including Non-destructive testing, dimensional inspection, material analysis, etc., to ensure every part meets the highest standards.

6. What is the typical lead time for casting orders?

Lead time depends on the complexity and volume of your order. Typically, the casting cycle is 25-40 days.

7. What are the advantages of casting compared to other manufacturing methods?

Casting allows for the production of complex shapes with high precision, while offering economic benefits. It also minimizes material waste to the greatest extent and provides excellent flexibility in material selection.

8. Is your casting process sustainable?

Yes, we prioritize sustainability in our casting processes by strictly adhering to local environmental regulations by minimizing material waste, recycling scrap, and utilizing energy-efficient equipment. This ensures high-quality results with minimal environmental impact.
