A set for the window, not only a box of parts

AOHUALUN makes the parts a window needs to open, lock and stay put: handles, hinges, transmission rods, multi-point locks, cylinders, crescent locks, rollers, friction stays and wind bracing.

They are supplied two ways — matched to a window system, or as individual items with catalogue numbers kept exactly as printed for repeat orders.

For window fabricators

Match hardware to your window system

Check the sash types and the profile groove first, then the parts list with catalogue numbers. Each system page carries its own set, drawing and sizing notes.

For distributors and stockists

Browse by component

Eight component families with catalogue numbers, so a repeat order is the same part as last time. Representative models are quoted per family; the full model list comes on request.

One plant, from drawing to packed carton

Making the moulds, castings and pressings ourselves is what lets us adjust a fixing pattern, a colour or a handle shape for a customer instead of selling only from stock.

Assembly workshop at the AOHUALUN plant, with benches and component crates in rows — Assembly workshop — sets are built and checked against the parts list.

Design and mould developmentDrawings and moulds are made in house, so a fixing pattern can change without changing supplier.
StampingPresswork turns strip into the stays, rods and locking parts that go on a sash.
Die castingHandles, hinges and lock bodies are cast in the tool shop, then trimmed for assembly.
Injection mouldingPolymer parts — rollers, guides, spacers — are moulded on site.
Surface finishingParts are finished in the colour and surface the order asks for before assembly.
Assembly and packingSets are assembled, checked against the parts list and packed for the order.

Injection moulding area at the AOHUALUN plant — Injection moulding area — polymer rollers, guides and spacers.

Finished goods warehouse with stacked crates at the AOHUALUN plant — Finished goods store — packed sets ready to ship.

Custom colour, a different fixing pattern or a handle shape of your own: send the drawing and we will check it against the tooling.
