Quality Control
WEITE focuses on stable quality control from raw materials to final delivery. Every product batch undergoes rigorous inspection and testing to ensure consistent performance for our global customers.
QC Process Flow
Our quality control system covers every stage of production, ensuring that every product meets your specifications.
Raw Material Checking
Incoming steel, zinc alloy, aluminum and plastic materials are tested for composition, thickness and mechanical properties before entering production.
Mold/Tooling Checking
Molds and tooling are inspected for precision and wear before each production run to maintain dimensional accuracy.
Production Inspection
In-process inspection during stamping, die-casting and assembly ensures defects are caught early in the production line.
Surface Treatment Inspection
Plating, painting and coating quality are checked for uniformity, adhesion, color matching and corrosion resistance.
Assembly Checking
Assembled products are checked for fit, alignment, fastener torque and smooth operation before further testing.
Function Testing
Each product undergoes function testing including opening cycles, load tests, damping performance and movement smoothness.
Final Inspection
Finished products are inspected against approved samples and specifications using AQL sampling standards before packing.
Packing Inspection
Packaging quantity, labeling, barcode scanning and export carton condition are verified before shipment.
Testing Capabilities
Our quality lab is equipped to perform a range of tests to verify product durability, safety and performance.
Opening & Closing Test
Hinges and slides are tested for 80,000+ opening and closing cycles to verify long-term durability and consistent performance.
Load Capacity Test
Drawer slides and lift-up systems are tested under rated load conditions to confirm smooth operation and structural integrity.
Salt Spray Test
Surface finishes undergo 72-hour salt spray testing to evaluate corrosion resistance and coating quality per ASTM B117 standards.
Surface Finish Inspection
Visual and instrumental inspection of surface finish quality including color consistency, gloss level and defect detection.
Dimension Inspection
Precision measurement using calipers, gauges and CMM equipment to verify all dimensions match engineering specifications.
Packaging Inspection
Export packaging is inspected for structural integrity, moisture resistance and labeling accuracy before container loading.
Our Quality Commitment
Stable quality, reduced defects, long-term supply, suitable for bulk orders and overseas customers. We maintain consistent quality standards across every production batch, giving you confidence in your supply chain.
