Our Precision Manufacturing Workflow
Ensuring engineering certainty from inquiry to delivery.
01｜Inquiry
02｜DFM Review
03｜PO Confirmation
The customer sends requirements or drawings.
What we do:
Rapid assessment of product type, machining difficulty, and estimated lead time.
Our engineers conduct a full DFM (Design for Manufacturability) evaluation, covering：
Review of feature accessibility, minimum wall thickness, and overall machinability.
Evaluation of mechanical rigidity and fastening design for stable assembly and long-term use.
Identification of high-cost or high-risk features, with suggestions to simplify machining and improve efficiency.
We confirm pricing, lead time, quantity, payment terms, and enter the formal production workflow.
