Who We Are
Eastmaster was founded in 2001 in Shenzhen, China — a city that would become the world's manufacturing capital. What started as a small machining workshop has grown into a full-service precision manufacturing company serving clients across 30+ countries.
Over 25 years, we've seen the industry evolve. Product lifecycles have shrunk. Supply chains have fragmented. The demand for flexibility has never been greater. We've adapted — expanding from a single machining operation into CNC precision machining, injection molding, and in-house mold making — while staying small enough to care about every detail.
We don't just make parts. We help you bring ideas to life — whether it's a single prototype or a production run of thousands.

Quality Is Not an Afterthought
Every part that leaves our factory goes through a structured quality process:
1. Incoming Material Inspection — We verify every batch of raw material against specifications.
2. In-Process Monitoring — First-article inspection and periodic checks during production.
3. Final Inspection — CMM measurement, visual inspection, and functional testing as required.
4. Documentation — Inspection reports, material certificates, and full traceability available on request.
We are committed to continuous improvement and hold ISO certifications for our quality management systems.
What Sets Us Apart
Flexibility Without Compromise
Most manufacturers want large orders. We're built for the opposite. Whether you need 1 prototype or 10,000 production parts, we deliver the same precision and attention to detail.
Material Mastery
We work with materials that many shops avoid: PEEK, PTFE (Teflon), Delrin, UHMW-PE, machinable glass ceramic, and more. Our team understands the unique properties and challenges of each material.
In-House Mold Making
We don't outsource our molds. From DFM analysis to final T0 sample, mold design and fabrication happen entirely in-house. This means faster turnaround, lower costs, and full control over quality.
Design Partnership, Not Just Execution
We don't just quote your drawing and ship parts. Our engineering team reviews your design and often suggests optimizations — reducing cost, improving functionality, or simplifying manufacturing.
Speed When It Matters
- CNC parts: 1–10 days standard, expedited service available
- Mold T0: 20–30 days standard
- Prototype mold: 15–20 days
- Located in Shenzhen with direct access to major couriers (DHL, FedEx, UPS) for fast international delivery
