Process: A pattern is placed in sand to form a mold; molten metal is poured into the cavity. Suitable for large parts and low to medium volumes.
Typical products:
- Machine tool beds and frames
- Large pump bodies and valve bodies
- Wind turbine hubs and main shafts
- Construction machinery arms and counterweights
- Marine propeller brackets
Advantages: Low tooling cost, accommodates very large parts (up to several tons), wide material choice.
Process: A wax pattern is coated with ceramic slurry to form a shell; wax is melted out, then molten metal is poured into the shell. Ideal for complex, near‑net‑shape parts.
Typical products:
- Turbine blades and vanes (aerospace)
- Impellers and rotors
- Surgical instrument handles and orthopedic implant prototypes
- Valve balls and stainless steel fittings
- Complex brackets with internal passages
Advantages: Excellent surface finish (Ra 1.6–3.2μm), tight tolerances (±0.1mm), thin walls possible, minimal post‑machining.
Process: Molten metal is injected into a steel mold (die) under high pressure. Suitable for high‑volume production of non‑ferrous alloys.
Typical products:
- Automotive engine blocks, transmission housings, electric motor housings
- Consumer electronics frames
- LED heat sinks
Advantages: Fast cycle times, good surface finish, dimensional consistency.
Process: Metal is poured or pressurized into a permanent mold under low pressure. Combines good mechanical properties with moderate tooling cost.
Typical products:
- Automotive wheels
- Cylinder heads
- Structural suspension components
- Battery trays for electric vehicles
Advantages: Lower porosity than high‑pressure die casting, suitable for heat‑treatable alloys.
Process: A foam pattern is embedded in sand; molten metal vaporizes the foam and fills the cavity. Good for complex, one‑piece castings.
Typical products:
- Engine blocks with integrated internal passages
- Complex valve bodies
- Art/sculpture and industrial machinery components
