Step 2

Product Design

Send us your 2D/3D drawing (STP file be favored ) or physical samples. Once we get your file, our engineering team jumps right in. They will help you optimize the design for manufacturing.
Step 3

DFM Analysis Report

Before we cut steel, we look for problems. DFM report ensures your product is practical, safe and ready for flawless production. We confirm material, cavity, tooling life, tolerance, hardness, surface finish.
Step 4

Confirm Order & Make Tooling

After confirm order with payment, engineers build the 3D model and run flow analysis to spot defects. Then, high-precision CNC machines fabricates the mold, followed by trial runs and final adjustments for perfection.

Step 5

T1 Sample Confirmation
