Quality Control

Zero-Defect Quality Control System & Testing Protocols

Our entire production process operates under strict ISO 9001 specifications. We ensure absolute chemical traceability and structural integrity in every production run.

Three-Stage Quality Management Flow

From incoming raw material to outgoing shipment, every component passes three mandatory quality gates.

Incoming Material Control IQC

1. Incoming Material Control (IQC)

Every batch of rubber compound, plastic pellet, and polyurethane chemical undergoes rigorous density, rheology, and moisture analysis. We enforce 100% traceability back to original manufacturer COAs (Certificate of Analysis).

In-Process Quality Control IPQC

2. In-Process Dimension Control (IPQC)

Utilizing advanced automatic optical projectors and digital calipers directly at the production lines. Molded parts are pulled and dimensionally checked every 2 hours to prevent tolerance deviation.

Outgoing Inspection OQC

3. Outgoing Inspection & Reports (OQC)

Before shipment, we simulate real-world mechanical and environmental stress. We deliver FAI (First Article Inspection) and PPAP Level 3 documentation, tensile strength logs, and Shore hardness reports with your delivery.

Our In-House Metrology & Physical Testing Laboratory

State-of-the-art equipment for full physical property verification on every production lot.

Tensile Tester

Electronic Tensile Strength Tester

Used to analyze absolute tensile strength, elongation at break, and tearing resistance of elastomers up to 10kN load.

Shore Durometer

Digital Shore Durometer (Shore A / D)

Precision hardness verification across all rubbers, TPU, silicones, and engineered plastics, ensuring compliance with specifications.

Optical Projector

Digital Optical 2.5D Projector

Non-contact dimensional scanner providing cross-section visual measurement accurate to Β±2 microns.

Compression Set Testing

Compression Set Testing Station

Evaluate the long-term elastic recovery of elastomeric compounds under constant deflection.
