Custom Investment Casting for Complex, Application-Driven Parts

From design review to production-ready castings — engineered to reduce manufacturing risk, not just meet drawings.

  • Design-for-Casting Support
  • Casting + CNC Finishing in One Flow
  • Controlled Process, Predictable Results

Is Investment Casting Right for Your Part?

Investment casting is ideal for producing complex metal components — but it’s not the right solution for every project.

Lost wax casting is for you if your project requires:

Complex geometry, thin walls, or internal passages
Medium volumes where tooling cost is justified
Net-shape parts to reduce extensive CNC machining
Strength, weight, and design freedom all matter

Typical Parts We Cast

We focus on parts where geometry complexity and functional requirements make process control critical.

Machinery & Industrial Castings

Pump bodies, valve housings, gear housings, and structural components with complex geometry.

✔ Complex internal passages
✔ Post-CNC machining for critical dimensions
✔ Stable quality for continuous mass production

Automotive & Powersports Parts

Exhaust components, brackets, and functional parts requiring thin walls and dimensional consistency.

✔ Thin-wall casting capability
✔ Heat-resistant materials available
✔ Suitable for medium to large batch production

Hardware & Structural Components

Connectors, load-bearing parts, and custom fittings designed for cost-effective mass production.

✔ Reduced machining compared to fabricated parts
✔ Consistent dimensions across batches
✔ Cost advantages for higher volumes

How We Reduce Risk in Investment Casting Projects

Most casting failures don’t come from the process itself, but from decisions made before production starts.

Design-for-Casting Review

We identify high-risk features early and provide manufacturability feedback before tooling.

Controlled Casting for Complex Geometry

Gating design, material selection, and process parameters are defined for stability, not just feasibility.

CNC Machining on Critical Features

Instead of over-machining, we machine only where function and tolerance demand it.

Validation Before Mass Production

We provide samples and pilot runs ensure consistency before scaling to production.

Engineering Manager
Communication was easy and fast. They helped us figure out the right material and delivered exactly what we asked for. Pretty rare to find a supplier this reliable in China.
testimonial sarah johnson
Sarah Johnson
Purchasing Director
We were looking for a backup supplier but ended up making them our main one. Pricing was fair, but more importantly, the consistency was there. Every batch met our QC without surprises.
testimonial emily davis
Emily Davis
Supply Chain Manager
The castings arrived finished and ready to use, which cut weeks off our schedule. Quality was solid, and the team was flexible with our changes. We’ll definitely order again.

FAQ

What is the minimum order quantity (MOQ)?

Our MOQ depends on the material and casting size. Typically, we handle B2B orders starting from 50–500 pieces per design.

Because creating the wax pattern mold is required, a very low MOQ may result in a significantly higher unit price.

Yes. We offer heat treatment, CNC machining, sand blasting, bead blasting, polishing, powder coating, anodizing, and painting. Custom finishes are also available.

Absolutely. Our engineers can review your CAD designs, provide casting feasibility advice, and support prototyping before mass production.

Yes. We ship worldwide and have experience handling customs and logistics for overseas B2B clients.
