Sample DFM Report: What a Free DFM Review Actually Includes
A real example of the Design for Manufacturability notes Ginwate sends back with every quote. Five categories of feedback you get — features that won't machine, tolerances that cost too much, material substitutions that save 30%.
How to Prepare CAD Files for a CNC Machining Quote
A practical checklist for engineers: STEP vs IGES, what to include in your drawing, how to flag critical dimensions, and how to avoid the back-and-forth that delays your quote.
China CNC Supplier Checklist for Procurement Teams
Twelve checks every procurement team should run before placing the first PO with a China CNC shop. Certifications, sample reports, IP handling, and the questions that surface red flags fast.
No-MOQ CNC Machining: Why It Matters and How It Works
Most China shops have minimum order quantities. Here's why no-MOQ matters for startups, what the realistic economics look like, and how shops without MOQ stay profitable on 1-piece orders.
