VTR QC inspects initial production samples prior to mass production, or at the beginning of mass production, to ensure that product specifications are being met. Care at this stage avoids unnecessary reengineering delays and costs.

This check is performed when around 30% of an order has been completed. It can uncover problems during actual production and ensure that contractual obligations are being met. It also helps you determine whether the production process is on schedule.

This stage is normally carried out when production finishes and at least 80% of products are packed and ready for delivery from the factory or warehouse. Samples are selected at random according to AQL sampling standards and procedures, to ensure that finished goods conform to your specifications.
