Inspection & Supervision
Production Process Inspection & Shipment Supervision
Strict in-process controls and documented shipment inspections ensure stable production quality and fully traceable delivery.
Profile Dimension Verification
Measure profile wall thickness, width, and dimensional tolerances to ensure specification compliance.
Extrusion Line Monitoring
Monitor extrusion parameters in real time to maintain stable processing conditions and consistent profile quality.
In-Process Dimensional Check
Inspect slot dimensions, opening dimensions, and other critical features during production.
Pre-Shipment Photo Supervision
Document product appearance, packaging, quantities, and loading conditions before shipment.
Laboratory Quality Assurance
Three-Level Laboratory Quality Assurance System
Material integrity, structural performance and environmental durability are verified through a coordinated testing program.
Material Integrity
Consistent PVC formulation and processing stability begin with strict raw material control.
- Specific Gravity / Density
- Moisture Absorption
- Melt Flow Rate
- Rheological Performance
Structural Performance
Mechanical testing verifies the strength, stiffness, and impact resistance required for reliable PVC fence and railing systems.
- Tensile Strength
- Flexural Strength & Modulus
- Drop Weight Impact
- Impact Strength
Environmental Durability
Accelerated testing evaluates long-term outdoor resistance to weathering, UV resistance, heat, and aging.
- Accelerated Xenon Weathering
- Heat Deflection Temperature
