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

Orange peel

Possible causes

· Excessive preheating temperature of the substrate.
· Over rolling curing time of the coating.
· High coating viscosity with poor flow and leveling.
· Excessive spray air pressure.

Solution

· Reduce the preheating temperature.
· Strictly follow the rolling curing instructions.
· Shorten the rolling curing time or consult the technical department.
· Reduce the spraying air pressure.

Sagging

Possible causes

· Substrate preheating temperature is too low; material is too thin or uneven in thickness; spraying area is too large.
· Single-pass coating is too thick; coating flow rate is too high; spray distance is too short; poor atomization; spray gun traveling speed is too slow.
· Environmental factors: low temperature and high humidity.

Solution

· Slightly increase the substrate preheating temperature.
· Adjust the spray line speed, spray distance, and coating flow rate.
· Apply temperature-controlled drying to the spray line.

Shrinkage cavities

Possible causes

· The substrate surface has oil, dirt, or other contaminants.
· Coating rolling curing time is too short, resulting in incomplete curing.
· Air compressor malfunction causes moisture in the compressed air.
· Ambient humidity is too high.

Solution

· Perform substrate cleaning before spraying.
· Strictly follow the rolling curing instructions.
· Perform maintenance on the air compressor.
· Apply temperature-controlled drying to the spray line.
