Process selection, tolerances, finishes and sourcing practice, written by the engineering team that quotes the work. No gated PDFs.
Compare CNC machining and sheet metal fabrication on cost, tolerance, volume and lead time, with a decision table for picking the right process.
When does die casting beat CNC machining? Compare tooling, per-part price, tolerance and lead time, and calculate your own break-even volume.
A 12-point checklist for how to choose a manufacturer in China: test engineering depth, QC documents, IP protection and landed cost.
A sheet metal fabrication design guide: bend radii, K-factor, hole-to-bend distances, tolerances and hardware, in nine rules that cut cost.
Rapid prototyping methods compared: SLA, SLS, FDM, CNC machining, sheet metal and casting, judged on lead time, accuracy, strength and cost.
Anodizing or powder coating? Compare corrosion resistance, color options, dimensional impact, masking and cost before you specify a finish.
How ISO 2768 general tolerances work, what the f, m, c and v classes mean, and when to switch to GD&T so parts cost less and fit better.
Low-volume manufacturing: choosing between CNC machining, soft tooling and hard tooling for 10 to 5,000 parts, and when a mold pays back.
The seven drivers behind CNC machining cost, from stock removal and setups to tolerance and finish, plus the DFM changes that cut 10–30%.
How NDA and IP protection work in practice when sourcing custom parts from China: drawing control, sub-suppliers, tooling ownership and inspection.
