Materials
We work with a broad selection of thermoplastics and engineering resins. Our materials team helps you choose the right grade based on your product's working environment, mechanical needs, and budget. Common options include:
Special grades available on request: flame-retardant, UV-stabilized, glass-filled, food-grade, and recycled materials.
Our Process
We provide a full one-stop service. You deal with one trusted manufacturer from day one — no middlemen, no delays, no miscommunication. Here is how we work with you:
Send us your 2D drawings, STEP/IGS files, or even a hand sketch. We review your design and suggest improvements to cut costs, improve quality, and speed up production.
Our engineers run Design for Manufacturability (DFM) checks and mold flow simulation to find thin walls, draft angle issues, or warpage risks — before cutting any steel.
Molds are designed and built in-house to ±0.005mm precision, using standardized cooling channels to reduce warpage and shrinkage.
We produce T1 samples for your testing and approval. Sample costs are credited back against your first production order.
Once approved, full-scale production begins. Multiple molds run in parallel to shorten lead times. Capacity: up to 2,000,000+ parts per month.
Every batch goes through material verification, first-article inspection, in-process checks, and final inspection with full reports.
