About Die Casting

What are the minimum tolerance requirements for certain precision aspects of the product? What is the minimum draft angle, and what about linear and angular tolerances?

The minimum tolerance requirements depend on the size of the product.

For dimensions up to 200mm, tolerances of ±0.1 or better are required.

For dimensions up to 300mm, tolerances of ±0.2 or better are necessary;

and for dimensions up to 500mm, tolerances of ±0.3 or better are expected.

As for draft angles, a minimum of 1 degree is required, but larger angles are preferred for smoother ejection from the mold.

These tolerance specifications are essential to ensure the precision and quality of die-cast products.

What about the lifespan of your die casting mold?

50,000 교체 또는 개조 전 사진. If the old die-casting mold reaches the end of its service life, we can replicate a new mold for you free of charge.

What are the differences between cold chamber & hot chamber die casting? (Cold chamber die casting VS hot chamber die casting)

콜드 챔버 다이 캐스팅: This method is suitable for materials with higher melting points like aluminum and magnesium. The metal is melted in a separate furnace and then injected into the cold chamber machine. It’s ideal for casting durable and lightweight parts but can be a bit slower due to the need for metal transfer.

핫 챔버 다이 캐스팅: Designed for materials with lower melting points, such as zinc. In this process, the metal remains in a molten state within an integrated furnace connected to the machine. Hot chamber die casting is faster and more efficient for casting smaller, intricate parts, making it cost-effective for high-volume production.
