Quality control is implemented as a multi-stage inspection system covering raw materials, component assembly, system testing, and final shipment inspection.
Incoming Material Inspection
Before production begins, key components are inspected based on functional and durability requirements:
Only materials that pass inspection are released to production lines.
Engine components verification (model matching and specification check)
Steel structure material thickness and grade inspection
Hydraulic system component sealing and pressure resistance check
Transmission parts dimensional accuracy inspection
Assembly Process Inspection
During assembly, inspections are performed at each major stage:
Any deviation detected during assembly is corrected before moving to the next stage.
- Chassis alignment and welding quality check
- Transmission installation accuracy verification
- Axle and drivetrain assembly inspection
- Hydraulic pipeline connection sealing test
Hydraulic System Testing
Hydraulic systems are tested under controlled pressure conditions to verify:
Load-bearing stability
Oil leakage resistance
Cylinder response speed
Multi-function hydraulic output performance
Engine Performance Check
Each tractor engine undergoes functional testing before final assembly approval:
Engine testing ensures operational reliability before shipment.
Idle stability check
Load response performance test
Temperature resistance evaluation
Fuel system stability verification
Pre-Shipment Inspection (Final QC)
Before packaging and container loading, a full inspection is carried out:
Only fully qualified units are approved for shipment.
