4-Stage Quality Assurance System
We have our own lab for testing raw materials and finished products in order to minimize defective products as much as possible.
Raw Material Testing
Ensuring batch consistency
Mixture Validation
Formula accuracy check
Production Inspection
Triple-layer quality control
Performance Testing
Strength & heat resistance
Detailed Quality Control Procedures
Our in-house lab and dedicated QC team ensure every product meets the highest standards
Stage 1: Raw Material Testing
Each batch of incoming materials undergoes rigorous testing before entering production:
PVC resin and additives viscosity tested with torque rheometer
Color materials (masterbatch, ASA resin) checked using two-roll milling machine
Batch-to-batch color consistency verification
Material viscosity matching for uniform production
Stage 2: Mixture Validation
After mixing, we validate the compound to ensure precise formulation adherence:
Mixture viscosity verified with torque rheometer
Precision measurement of mixing proportions
Homogeneity testing for consistent material properties
Formula compliance certification
Stage 3: Production Inspection
Triple-layer inspection during manufacturing ensures immediate defect detection:
A part of our QC team continuously monitor extrusion lines
Another part of the team check all the finished products in the designated area
QC team leader will do spot checking on extrusion and post sanding process.
Stage 4: Performance Testing
Finished products undergo rigorous testing to guarantee performance standards:
Bending strength tested with universal testing machine
Heat resistance verified with HDT/Vicat testing machine
Direct sunlight simulation for durability assessment
Our Quality Commitments
Certifications and standards that guarantee product excellence
