Zhenkai Tools/Factory
OUR PLANT

What is actually
inside the building.

Most factory pages say "advanced equipment" and stop there. Here is the count, the capacity, and the public record you can check it against.

Finished rivet guns stacked at the end of the Zhenkai Tools line
6aluminium die-casting machines
6 × 400 kgelectric melting furnaces
10injection moulding machines
16 × 80 tflat forming presses
3shot-blast machines
2,000,000rivet guns a year
400,000staple guns a year
1,000,000backrest brackets a year

Equipment and capacity as registered in the environmental approval for our production-line upgrade project (Cixi Ecological Environment Bureau, 2024). Phase one was completed in September 2025, with RMB 5.12 million actually invested.

Why the equipment list matters to you

Stamping, die-casting and injection moulding all sit under one roof. That means the body of a riveter, its handle grip and its nosepieces are made in the same building — so a change to a mould does not turn into a three-week exchange with a subcontractor.

It also means there is no trading house taking a cut between you and the people who set the tooling. When you ask for a different nosepiece thread, you are talking to the shop that cuts it.

HOW TO CHECK US

Audit us before
you trust us.

Look up the company Unified social credit code 91330282316889926U — paste it into China's national business registry and the legal representative (Zhang Sanbo), registration date (13 April 2015) and registered scope will come back on their own.
Check the GS certificate GS-Mark approval 50571636, TÜV Rheinland test mark 1111263764 — both searchable in TÜV Rheinland's own database, not just on our page.
Walk the line in person Tell us your dates and we will take you from the raw steel to the sealed box. The address on our registry entry is the same address you will drive to.
Walk it on video instead If a flight is not in the budget, ask for a live walk-through on WhatsApp — the presses, the QC bench and the finished-goods stacks, unscripted.
The part most suppliers skip. We would rather you verify the boring facts — registration, tax rating, the certificate number — before you send money anywhere. A buyer who checks is a buyer who comes back.
