Climate-Controlled Bridge CMM Metrology Lab

Every mold cavity block and core insert undergoes 100% First Article Inspection (FAI) verification against native 3D CAD before press trial assembly.

💡 Navigating Steel Provenance & International Standards: When sourcing tools overseas, selecting appropriate cavity grades via our mold steel selection guide (comparing S136, NAK80, H13, and P20) and verifying certified mill certificates (Uddeholm, Bohler, Daido, LKM) is critical to prevent premature stress cracking. For a complete procurement framework, read our guide on importing injection molds from China.

Frequently Asked Questions

How much does a custom injection mold cost in China?+

Custom injection mold costs depend on part size, complexity, cavity count, and SPI classification. Prototype molds (SPI Class 104-105) typically range from $1,800 to $5,000. Multi-cavity production molds (SPI Class 101-102) with hot runner systems for engineering resins range from $8,000 to $45,000+. Sourcing from China provides a 40% to 65% direct cost reduction compared to North American or European tooling while matching DME/HASCO export standards.

How long does it take to get the first sample (T1) after placing a mold order?+

Typical lead time to T1 sample is 25 to 45 calendar days depending on mold complexity. Rapid prototype tooling can achieve T1 in 15-20 days. High-precision connector molds (±0.002mm) or large home appliance molds (20+ tons) take 35 to 60 days including full 3D DFM review, Moldflow simulation, CNC machining, mirror EDM, and initial trial testing.

What is the minimum order quantity (MOQ) for custom injection molding and tooling?+

We have no minimum order quantity (MOQ 1 set) for mold building. For molding production, we support bridge tooling batches from 500 parts up to continuous multi-million shot mass production runs across 45T to 3,000T injection molding machines.

Do you offer free DFM analysis and Moldflow simulation with every mold quote?+

Yes. Every RFQ submitted with 3D CAD files (STEP/IGES/X_T) receives a complimentary, engineering-grade DFM (Design for Manufacturability) analysis report within 24 hours. The DFM covers draft angle validation, wall thickness uniformity, parting line placement, gate location optimization, and potential sink mark or warpage risks before cutting steel.
