Casting is suitable for producing complex parts with precise dimensions. It helps reduce overall machining costs and, in some cases, eliminates the need for secondary processing.
Unitedparts provides two main casting processes: Investment Casting (Lost Wax Casting) and Die Casting.
Investment Casting (Lost Wax Casting)
-
Features:
1. Manufactures hollow, curved, mesh-like parts, as well as parts with varying wall thickness.
2. The desired balance of ductility and hardness can be achieved through material selection and heat treatment.
3. Involves multiple process steps, suitable for medium-volume production. -
Materials:
Suitable for ferrous metals, such as stainless steel and carbon steel.
Commonly used materials: 4140, 8620, SUS304.
-
Applications:
Automatic door parts, automotive parts, and agricultural machinery parts.


Die Casting
-
Features:
1. Thin-walled and intricate parts with excellent dimensional stability, precise tolerances, and refined surface quality.
2. Non-ferrous alloys make die-cast parts lighter.
3. High production efficiency, supporting consistent mass production. -
Materials:
Applicable only to low-melting-point non-ferrous alloys such as aluminum, zinc, and magnesium.
Commonly used materials: ADC10, ADC12, Zamak 3.
-
Applications:
Wheelchair parts, automotive parts and hardware parts.
