Blanking, heat treatment, grinding and inspection all run in-house — so the tolerances we quote are the tolerances we control.
Buyers audit suppliers before they commit. Here is the operational picture up front.

Distributors and equipment brands need a supplier whose output does not wobble with the season.
| Stage | Equipment | Capability |
|---|---|---|
| Blanking | CNC blanking / stamping presses | Profiles up to 1,200 mm |
| Heat treatment | Salt bath quench line + tempering furnace | 45–55 HRC, automated low-temp temper |
| Grinding | Surface & edge grinders | Bed knife edge grinding, flatness control |
| Balancing | Blade balancing equipment | Vibration control for rotary blades |

| Inspection | Rockwell hardness tester, CMM, gauges | Batch hardness + dimensional records |
Manganese steel strip verified on arrival; grade and thickness checked against the mill certificate.
Profile cut to drawing, centre hole and mounting features formed.
Salt-bath quench and low-temperature temper to reach target hardness.
Edge ground where required, blade balanced for smooth running.
Black oxide, phosphate or coating applied for corrosion resistance.
Stamping, hardening, metrology and packing on one site in Guangde, Anhui. Everything below — film and photos — was shot on our own floor. No stock imagery.
Most export programmes do not start with a tidy CAD file. They start with a worn sample or a competitor's part number. Our engineering team works backwards from that.
We run video factory audits for serious buyers — walk the lines without booking a flight.
