Process, in order
Eight stages from plate to crate. A buyer audit normally takes half a day.
Laser and plasma cutting of wear plate to nesting.
Press brake forming of housings and side plates.
Robot arc welding with preheat and controlled interpass temperature.
Vibration and thermal relief before machining.
CNC boring, turning and milling on a single datum.
Quenching and tempering of pistons, chisels and bushings.
Clean-line assembly, torque records per unit.
Load test, powder paint, fumigation crate.
Quality control
Incoming plate is checked for grade and hardness. Welds are visually inspected on every unit and ultrasonically on the load-bearing seams. Machined bores are gauged. Every hammer leaves with a signed test sheet.
- Material grade and hardness
- Weld inspection, UT on seams
- Bore and fit gauging
- Load test and record sheet
Capacity and lead time
Standard models are held in parts, so a single hammer normally ships in 7–12 days. A mixed container of twelve units takes 20–25 days. OEM colour and plate work adds one week.
Auditing us
We host buyers and their inspection agents. Airport pickup from Linyi or Qingdao, interpreter on request, and the test bench can be run for you.
