Gear and Shaft Manufacturing Process
Every gear and shaft follows a controlled manufacturing process designed to ensure strength, consistency, and dimensional accuracy.
1. Material Verification
Raw materials are inspected and verified before production begins.
2. Hot Forging
Forging refines the internal grain structure and improves mechanical properties.
Material properties are optimized according to application requirements.
4. Rough Machining
Excess material is removed while maintaining process allowances.
5. Gear Hobbing or Gear Shaping
Gear teeth are generated according to specified geometry.
6. Gear Grinding
Critical gear surfaces are finished to improve accuracy and surface quality.
Final machining ensures dimensional compliance and assembly fit.
8. Inspection and Testing
Dimensional, material, and non-destructive inspections are performed before shipment.

Quality Control and Inspection Standards
Quality control is essential for gears and shafts because transmission parts work under constant mechanical stress. Small defects can cause vibration, wear, or early failure. Weforging uses a multi-stage inspection system to guarantee stable performance and batch consistency.
Our inspection standards include:
Ultrasonic testing for internal defects
Magnetic particle inspection for surface cracks
Hardness testing after heat treatment
CMM dimensional measurement
Gear tooth profile analysis
Surface roughness verification
Full material traceability documentation
Every gear and shaft is inspected according to OEM specifications and international industrial standards. Inspection data is recorded for quality audits and export compliance.
Reliable inspection reduces downtime risk and ensures long service life in real operating environments.
