Insights & Resources

Practical guides on CNC machining, materials, tolerances, and working with manufacturing partners in China — written by our engineering team, not marketers.

What We're Writing About

Our first articles are in the works. Each series answers the questions our customers actually ask during quoting and production.

DFM Design Guides

Wall thickness, undercuts, tolerance stacks, thread design — how to draw parts that are cheaper and faster to machine, before you send the RFQ.

  • Designing for 5-axis access
  • Tolerance callouts that don't inflate cost

Material Selection

Aluminum vs. stainless vs. PEEK — strength, corrosion, cost, and lead time compared for real part scenarios, not textbook tables.

  • 6061 vs. 7075 for structural parts
  • When plastics beat metals

Cost Breakdowns

What actually drives CNC pricing: setup time, tolerances, finishes, quantity curves — so you can quote-compare suppliers on equal footing.

  • Why quantity pricing isn't linear
  • Finishing costs, explained

Quality & Inspection

What a professional inspection report looks like, when to ask for CMM data, and how to verify parts before they leave the factory.

  • Reading a dimensional report
  • First-article inspection, step by step

Sourcing from China

Shipping terms (DDP / FOB / EXW) demystified, lead-time planning, and how to run a smooth RFQ process with an overseas partner.

  • Incoterms for machined parts
  • Building a supplier shortlist
