Aluminum window & door machinery — since 1999

Why Qianzheng

The difference shows up in year five.

Most machines look the same on a quotation. They stop looking the same when a factory runs three shifts, changes profile suppliers, and needs a part on Thursday.

01

Accuracy that survives production

Ground guideways, stress-relieved frames, servo positioning and hydraulic clamping. Saws are test-cut on the profile thickness you actually buy — not on a demo bar.

  • ±0.1 mm repeatable positioning on CNC axes
  • 45° and 90° cutting with automatic angle switch
  • In-house machining of frames and spindles
02

A line, not a list

We quote stations as a workflow. Cycle time, buffer space, crane access and operator count are settled before you sign — so the machines do not arrive faster than your floor can absorb them.

  • Factory layout drawing included
  • Tooling and consumables list per profile system
  • Capacity modelled per shift
03

Service with a name on it

Every export market has a named after-sales engineer. Remote diagnostics over video, then a spare-parts warehouse stocked for the models we still support.

  • Reply within one working day
  • Installation and operator training on site
  • English manuals and commissioning checklists

Questions buyers ask

Straight answers.

Can you design the layout for my factory?

Yes. Send the floor plan and your profile system; we return a layout with machine positions, buffer zones, power and air requirements. It is included with every quotation.

What is the typical delivery time?

Standard single machines ship in 30–45 days. A turnkey line is typically 60–90 days from deposit, plus sea freight.

Do you install and train on site?

Installation and training are quoted as an optional package. Our engineers travel, commission the line, train operators and sign a handover checklist with your team.

How do spare parts work after the warranty?

Common wear parts are stocked in our warehouse. We keep the BOM for every machine we ship, so a part can be identified from the serial number and dispatched quickly.

Can I visit the factory or see a machine running?

Yes — we host customers in Zouping and can arrange visits to reference factories running the same model. Video calls from the shop floor are also possible.
