During Production Inspection, is also know as DUPRO inspection. It is a type of quality control performed by a quality inspector. A During Production quality check is conducted at the factory, when 20% to 80% of the goods are manufactured and packed. It involves a specific quality control checklist that mostly focuses on :

  • • Identifying and preventing quality defects, non conformities
  • • Identifying and preventing late delivery in China
  • • Checking if packaging is well prepared

During Production inspection is thus very useful to those who want to check the quality of products from China early in the manufacturing process. It also facilitates production monitoring in the Chinese factory. JS Quality inspectors use AQL chart and ISO 2859-1 (ANSI/ASQZ1.4) standard to deliver reliable checks during production.

WHAT IS DURING PRODUCTION (DUPRO) Inspection?

A Dupro inspection is a quality control service that includes the following during production checks :

PRODUCT CHECK PRODUCTION CHECK
Dimensions & Weight Inventory of goods
Product Build Rate of Production
Core Components Assembly line
Workmanship & Appearance Casting & Coating line

Pacakging & Marks
factry

During production, we inspect a sample lot of products from China. This sample lot is defined as per ISO 2859-1 (ANSI/ASQZ1.4) standard. After a DUPRO, we compile all the findings in a report with photographs and send it to the Buyer.

WHEN does a DUPRO quality check on products from China happen?

During Production inspections are usually conducted when manufacturing of the order in China reaches 20% to 80% of completion. However, each and every product is not manufactured the same way.

Our DUPRO inspections are implemented at a specific time during manufacturing. Preferably when :

  • ‣ All parts & components have been delivered to the factory in China;
  • ‣ There are enough goods assembled to inspect a sample lot;
  • ‣ Coating & Assembly lines are both functioning;

Even though many business prefer to conduct quality checks before delivery, there are many shortcomings to relying only on these. A During Production quality check of goods from China is especially useful with :

  • – Suppliers with prior experience of defective products, or late deliveries;
  • – New suppliers and or new products;
  • – Products which manufacturing is outsourced by your Chinese supplier;
