Precision Parts Manufacturing
- The factory uses precision manufacturing: laser cutting and CNC machines are used to make all chain parts
- Full control of dimensions, tolerances, roundness and roughness are achieved
- Parts are machined to high precision for consistent quality chains
Chain Plate Hole
Forming
- Chain plate holes are shaved following laser cutting or punching, and milled if necessary.
- Very high level of hole smoothness is achieved to increase contact area and interference fit between plates and pin/bush.
Heat Treatment
- The in-house heat treatment at Zhejiang Laiyuan ensures all wear parts are optimally hardened
- Sealed quench and continuous furnaces and induction hardening are used.
Attachment
Welding
- All chain attachments are welded robotically
- Weldments are homogenous and achieve consistent adherence to specifications.
Sprocket Welding and Machining
- Sprockets are fabricated and machined in-house.
- Perfect match of chain to sprocket gearing for smooth entry/exit of roller to sprocket is ensured.
- Results in minimal vibration and low noise during operation.
