Complete hardware sets, by window type.

Ouzhilun makes the hardware that holds an aluminium or PVC window together — handles, transmissions, locking, hinges and stays — and supplies it as one set, matched to the window you build.

Why buyers take the whole set from us

The whole set, not a bag of parts

Handle, transmission, locking plates, hinges, stays and rollers are selected to work together, so a missing lock block does not stop the sash from closing.

See the component ranges

Tooling in the same building

Moulds are developed in-house, which is what lets a part be changed when a profile changes rather than replaced by something close enough.

How the factory works

Six processes under one roof

Die casting, stamping, injection moulding, surface finishing and assembly are done in the plant, with incoming checks and final inspection.
