Quality Control Process


Incoming wood fibres, polymers, additives, and colour materials are checked before production to help maintain stable product quality.

1. Raw Material Inspection

Material ratios, extrusion settings, profile dimensions, and surface finishes are confirmed according to the product specification before full production begins.

2. Production Setup

Samples (chosen randomly) are cut from each production batch and compared with approved reference samples to check colour consistency, surface texture, dimensions, and overall appearance.

3. Batch Sample Inspection

Selected samples are tested for key performance characteristics such as thermal stability, moisture resistance, impact strength, and dimensional consistency to confirm that the batch meets the required standards.

4. Batch Performance Testing

During extrusion and finishing, products are regularly inspected for profile shape, weight, surface defects, embossing quality, and structural consistency.

5. In-Process Quality Checks

Finished boards are checked for colour variation, dimensions, appearance, quantity, and conformity with the confirmed order requirements.

6. Final Product Inspection

Packaging, labels, accessories, quantities, and container loading are verified before shipment to help ensure products arrive safely and correctly.

7. Packaging and Loading Check
