Five Core Processes, One Factory
From mold design to final inspection — vertical integration keeps quality consistent and lead times short.
Gravity Casting
Stable, dense, low-porosity aluminum parts for structural and safety-critical components.
Learn more →Low-Pressure Casting
Tight-tolerance parts with excellent mechanical properties, ideal for wheels & motor housings.
Learn more →Sand Casting
Flexible low-volume production for large or complex aluminum castings.
Learn more →CNC Machining
3-, 4- & 5-axis precision machining to ±0.1 mm tolerance.
Learn more →Mold Design
In-house tooling — die, sand core, gravity mold — 4–7 day sampling.

A glimpse of parts we've produced. Custom shapes, alloys and tolerances available on request.
Robotic Arm Joint Housing
A hollow joint housing for collaborative robot arms, gravity cast in A356 and T6 heat-treated, then machined on 5-axis centres so the bearing seats and gearbox flange need no secondary work.

Industrial Robot Base
A structural base casting that mounts the robot pedestal to the floor. The gravity process gives the dense, defect-free section needed to resist the moment loads of a moving arm.

Auto Cooling System Part
A cooling-system housing produced in high volumes for automotive customers, supplied with 100% leak testing and full lot traceability for use on the vehicle assembly line.
View detail →
Aluminum Motor Housing
A thin-wall motor housing produced by low-pressure casting, a process that fills the mould under pressure and eliminates the gas porosity that would otherwise show up in an anodized finish.

EV Battery Enclosure
A structural battery-pack enclosure cast in low-pressure aluminium. The casting provides the stiffness and crash performance of a welded assembly with far fewer parts and joints.
View detail →
Medical Device Housing
A housing for a medical device produced by sand casting, a route chosen because the low tooling cost lets the customer iterate on design before committing to production tooling.
View detail →
Thermal Management Heat Sink
A cast heat sink with integrated fins. Casting fins into the part instead of bonding them removes a thermal interface and makes the assembly more reliable and cheaper.
View detail →
Rail-Transit Structural Bracket
A large structural bracket for rail-transit interiors and equipment mounting. Sand casting handles the size comfortably, and T6 heat treatment provides the impact strength demanded by rail standards.

We treat every RFQ as an engineering project. DFM review, alloy recommendation, tolerance analysis and rapid sampling are part of our standard service — not extras.
- DFM (Design for Manufacturing) review on every RFQ
- Material certificates: ADC12, A380, A356, AC4B, custom alloys
- In-house CMM, X-ray, spectrometer, tensile & metallographic inspection
- Typical lead time: sample 4–7 days, mass production 15–30 days
- English-speaking engineering & sales team in UTC+8

Inside Lvdewang's 10-Step Quality Control System
From incoming spectrometer check to final OQC — every step, every check, every record.
CNC Machining Tolerance 101: ±0.1 mm vs ±0.05 mm — What Does It Really Cost?
Tighter tolerances can multiply machining cost by 3–5×. Here's how to decide what's actually needed.
