Since 1989, plants and contractors across Malaysia have trusted Weng Loi Machinery to repair, recondition and remake machinery parts — fast. CNC & manual machining, one-stop, by engineers.
From emergency breakdown repairs to precision new parts — in metals, non-ferrous, plastics and composites.
Worn shafts, gears, rollers, screw conveyors and rotors restored to spec — so you don't wait months for an overseas replacement.
CNC lathes and a 12,000 rpm high-speed machining centre for accurate, repeatable parts — one-off or batch production.
Over 20 manual lathes and mills handle the big, odd and urgent jobs CNC shops turn away — up to ø1,600 mm and 5 m long.
Turn your drawing, sample or sketch into a working part. No drawing? We can measure and reverse-engineer from the worn original.
Adapt existing parts and machines to new requirements — resizing, re-boring, keyways, threads from M1 to M30.
Build-up welding on worn surfaces before re-machining, plus general fabrication to complete the job in one place.
WhatsApp a photo, drawing or sample of the part to Lily. No formal drawing needed — a phone photo with rough dimensions is enough to start.
Our engineers assess whether to repair, recondition or make new, and quote you the practical, economical option.
Machined, checked and ready to install. For urgent breakdowns, tell us — we understand downtime costs you money every hour.

Few shops in the region can swing ø1,600 mm or turn 5-metre shafts. We do both — alongside high-speed CNC work.

When a machine stops, everything stops. That's the problem Weng Loi Machinery has solved for plants, mills and contractors since 1989 — hundreds of clients served by consulting, designing and manufacturing optimised engineering parts, delivered by engineers.
Founded by Choo Tuon Loi, a machinist with over 50 years at the lathe, the company today runs a 19-person team that combines old-school machining craft with degree-qualified mechanical engineers and modern CNC capability.
We work across the full range of materials — steels, non-ferrous metals, plastics and composites — and we're investing ahead: 3D scanning, SLA/SLS 3D printing and multi-axis machining are on our roadmap.
