Casting Service

Everich delivers comprehensive custom casting solutions covering investment casting(lost‑wax), die casting, sand casting and gravity casting. Supported by ISO 9001‑certified foundry resources, we produce reliable cast parts for prototype verification, small‑batch trials and mass‑volume manufacturing from your 2D drawings or 3D models.

Main Casting Processes

**Investment Casting (Lost-wax Casting)**
Creates near‑net‑shape high‑precision parts for complex geometries hard to achieve via machining. Provides fine surface finish and stable dimensional performance, widely used for aerospace, medical and automotive stainless‑steel, alloy‑steel and high‑temperature‑alloy components.

**Die Casting**
Molten metal is injected into hardened dies under high pressure. Features fast cycle speed and excellent repeatability for mass‑production of aluminum, zinc and magnesium‑alloy housings and structural brackets.

**Sand Casting**
Sand acts as molding medium. Suits large‑size workpieces with relatively low tooling investment, suitable for machinery, pump and hydraulic parts in aluminum, cast‑iron, steel and brass.

**Gravity Casting**
Molten metal fills permanent molds under gravity. Castings obtain dense internal microstructure and superior mechanical performance, well‑suited for high‑strength aluminum and copper‑alloy structural components.

Why Choose Our Casting Service？

Wide Material Compatibility

Supports stainless steel, carbon steel, alloy steel, aluminum alloy, zinc alloy, magnesium alloy, brass, bronze and cast iron. Material grade will be matched according to your strength, corrosion‑resistance and temperature‑resistance requirements.

One‑stop Integrated Solution

Beyond casting forming, secondary operations including CNC machining, deburring, heat treatment and surface finishing are available. You can obtain ready‑to‑use finished components without multiple‑supplier coordination.

Flexible Production Volume

Accept low‑volume prototype casting and large‑scale mass‑production orders with no rigid MOQ, balancing cost for trial projects and bulk manufacturing.

Strict Quality Assurance

Full‑process inspection covers raw‑material incoming test, mold validation, first‑article inspection, dimensional check and non‑destructive testing(NDT). Material certificates and inspection reports can be supplied upon request.

Casting Service FAQ

What industries commonly use casting parts?

Aerospace, new‑energy & traditional automotive, medical devices, hydraulic & pneumatic components, industrial machinery, pump‑valve hardware, household appliances and power‑generation equipment.

Can you complete casting plus subsequent CNC‑machining within one order?

Yes. We offer integrated workflow: casting + secondary CNC‑machining + surface finishing, simplifying procurement and improving part fitting accuracy.

What documents do I need for quotation?

3D files (STEP/IGES/STP preferred), dimensioned 2D drawings with tolerances, material requirements, estimated quantity and surface‑finish needs. Physical samples are also acceptable for reverse‑engineering evaluation.

What are typical lead‑times?

Prototype casting:7‑15 working days. Mass‑production lead‑time varies with mold complexity and quantity; exact schedule will be offered after project review.
