The factory may involve incoming material control, process control, PPAP process, and others to ensure product quality and put the process in place.

Quality control assures that the manufacturer follows them during production to maintain the needed quality standards and reduce faults. It comprises, among other things, training, change control, documentation, audits, and investigations. The above belongs to the quality control within the factory.

However, quality control provided by the third-party inspection company is more about international trade between different countries and regions. It helps inspect your suppliers’ products’ quality, establish a bridge of trust between manufacturers and traders, and act as your supervisor. Hence, quality control is essential.

This procedure can ensure that the finished product meets the specified international index requirements. If it does not meet the standard, the supplier can be re-proofed to provide a higher-quality pre-production sample, and then mass production will be carried out according to this sample to sell to users.
