Here are the top 10 die-casting manufacturers in China, and introduces the various types of die-casting process and advantages of it.

Type of Die Casting

Low-pressure Die Casting

Low-pressure die casting is that molten metal introduced from furnace into cold mould and gas pressure hold the molten metal in the die until it solidifies. The production rates are fair and less than high pressure. Wall thickness is minimum 2-3 cm. The high yield is over 90% and trimming cost is low. The size of casting is limited due to machinery size. Surface finishing and minimum wall thickness are better than gravity die casting.

High Pressure Die Casting

High pressure die casting is a similar process to low pressure casting but requires complex machinery. It is suited to high production rates. The wall thickness can be as little as 1-2.5mm and the surface finish could be 1.5m. Pressure die casting has high strength due to the technology process. The size of casting is also limited due to machinery size. The start up cost is high that is suit to mass production.

Gravity die casting

Gravity die casting is molten metal poured into permanent cast-iron molds. The process fills with no force other than gravity. The production rates is higher than sand casting, but the mold cost is also higher than sand. Gravity die casting has a more smooth surface and better strength than sand casting due to rapid solidification. Another advantage is low possibility of gas porosity and thin wall thickness.

Aluminum Die Casting

Aluminum Die Casting is that molten metal injected with high pressure into mold cavity. There are hot and cold chamber machine. The most common material is A380, which provides the best material properties and cast-ability. Aluminum, magnesium, and zinc are three common alloys material in die casting.
Magnesium Die Casting compares to aluminum alloy parts, the weight is lighter than aluminum parts. Magnesium alloy die casting can have thin wall and complex structure of the part. Magnesium alloy AZ91D provides the highest strength compared with other magnesium die casting alloys.  The material properties is that outstanding corrosion resistance, smooth appearance, and excellent strength.

Zinc Die Casting

Zinc alloy parts compares to other alloy, it is the heaviest material that is commonly used for small part. Zinc alloys require lower pressure and temperature compared to aluminum and magnesium alloys. Therefore, the metal molds have less maintenance cost.

Benefits of Die Casting China

  1. EMI, RFI Shielding and can also act as an electrical ground for circuits.
  2. Speed of Production – Die Casting process is highly automated. Multi-cavity dies can also be used to speed up.
  3. Long Tool Life – 100000 – 200000 parts of identical die castings can be produced from a die tooling.
  4. Dimensional Precision – Dimensional tolerance are controlled by mold, thus high repeatability than machining.
  5. Cost Savings – Efficient, economical process for high volume production.
  6. Strength – Produces heat and wear resistant parts.
  7. Good Finish – Die cast parts can be manufactured with smooth or textured surfaces, and are easily plated or powder coated.
