Product ranges

Four machining ranges.One continuous workflow.

Cutting, corner crimping, end milling and CNC drilling — matched to the same tolerances so profiles move between stations without re-work.

All machines

Aluminum cutting Double-head precision saws, 45° cutting centres and corner-key saws that hold angle across a full shift. Explore range 02

Corner crimping Heavy-duty and 4-head CNC crimpers that close 90° corner-key joints without distorting the profile. Explore range 03

End milling Five- and six-blade end millers plus 7-axis CNC centres for clean, square profile end faces. Explore range 04

Drilling & milling CNC machining centres that drill, mill and cut in a single clamping — three faces without re-fixturing. Explore range

Automation Intelligent window & door production lines From 4-station aluminum lines to fully automated cutting, machining and assembly cells — engineered around your capacity, profile system and floor plan. Plan a line

130+precision machines in-house

Built in-house

We machine the parts that decide your tolerance.

Bases, columns and spindle housings are cut, milled and ground in our own plant instead of being outsourced. That is why a Qianzheng saw still holds angle after a decade of three-shift production — and why a spare part ships the same week, not the same quarter.

One factory, one standardCasting, machining, assembly and testing under one roof.
