Design for Manufacture: Five Drawing Choices That Decide Whether Your Part Machines Cleanly
A manufacturing engineer's DFM checklist: internal corner radii, thin walls, deep holes, standard threads, and tolerance stacking — and how each
Milling, turning, 5-axis, Swiss, materials, finishing and inspection — all under one roof in Chang'an Town, Dongguan.
Nothing here is brokered out to a shop we cannot audit. If your part needs milling, turning, EDM, finishing and inspection, it stays on our floor from raw stock to packed carton.

3-axis and 4-axis vertical machining centres for brackets, housings, plates and enclosures, from one-off prototypes to repeat batches.

Standard CNC lathes and live-tool turning centres up to Ø380 mm swing. Shafts, bushings, fittings, connectors and threaded components turned complete in one setup.
Learn more
5-axis machining centre (U400A) for complex, multi-face geometry in one setup. Angled features and compound surfaces finished in a single clamping.
Learn more
Swiss-type and sliding-head turning for long slender shafts, micro parts and high-volume turned components with sub-spindle and Y-axis work.

Aluminium 6061-T6 is our core material. Stainless steel, brass and engineering plastics are available on request.
Learn more
Anodizing, bead blasting, black oxide, zinc plating and laser engraving, then checked with in-house dimensional inspection.

When does a 5-axis machine lower cost per part instead of raising it? Setup math, fixture count, and a worked 6061 aluminum bracket, fully broken down.

Why Ra alone does not describe a surface, how cutter path, stepover, and nose radius drive finish, and where a surface grinder is the only right tool.
