Quality control standards and procedures

Quality control standards

We have a strong quality control team. From raw material procurement and production processes to finished product delivery, every step follows strict inspection procedures and is supported by advanced testing equipment.

During production, we ensure that every stage meets the established quality requirements through ongoing supervision and inspection. This ongoing quality control ensures the high quality of our products and enhances the company's market competitiveness.

Quality control process

We have a detailed and practical quality management system, mainly consisting of the following key stages: incoming material inspection, in-process quality control, and final inspection. These stages are interconnected and work together to ensure the overall quality of the product.

Incoming Material Inspection (IQC)s

In-Process Quality Control (IPQC)s

Final Inspection (FQC)s

Pinhole

Possible causes

· The viscosity of the coating is too high.
· The coating was sprayed too thickly and directly placed in a high-temperature oven, causing the surface to cure rapidly and the internal solvent to evaporate slowly.
· The temperature of the coating is too low.
· Bubbles in the coatings.

Solution

· Shorten the rolling curing time or consult the technical department.
· Reduce the coating thickness.
· Use the coating after it reaches room temperature.
· Consult the technical department.

Loss of gloss or uneven gloss

Possible causes

· Inadequate substrate surface preparation, with excessive roughness on the sandblasted surface.
· Coating degradation caused by excessive rolling curing time or low pH of Component A.
· Substrate preheating temperature is too high.
· Ambient humidity is too high.

Solution

· Re-perform substrate surface preparation.
· Shorten the rolling curing time or consult the technical department.
· Reduce the substrate preheating temperature.
· Apply temperature-controlled drying to the spray line.

Color difference

Possible causes

· Coating thickness (most significant impact).
· Curing performed before component A is fully dispersed.
· Cured coatings used after storage without being fully dispersed.

Solution

· Maintain the coating thickness within the normal range.
· Perform rolling curing only after component A is fully dispersed.
· Use the cured coatings only after it is fully dispersed.
