Manufacturing Process

From material selection to trial production

STEP 01

Raw Material Selection

We carefully select high-quality steel and alloy materials for critical machine components.

  • Crankshafts
  • Punch mechanisms
  • Cutting dies
  • Gear systems
  • Feed assemblies
STEP 02

Precision Machining

Machine components are processed using precision machining equipment to ensure dimensional accuracy and assembly consistency.

  • CNC turning
  • Milling
  • Drilling
  • Grinding
  • Surface finishing
STEP 03

Heat Treatment

Critical wear-resistant parts undergo heat treatment to improve hardness, wear resistance and service life according to engineering specifications.

  • Punches
  • Cutting dies
  • Transmission parts
STEP 04

Mechanical Assembly

Experienced technicians assemble each machine according to standardized procedures, and every stage includes functional verification before the next step.

  • Feeding mechanism
  • Gripping mechanism
  • Punching system
  • Cutting system
  • Transmission system
  • Lubrication system
STEP 05

Electrical Installation

Electrical components are installed and tested according to machine specifications.

  • Motor operation
