Why do you need In-Process Quality Control?

While the price is still the largest factor in attracting global buyers, quality is now considered equally important with the growth of consumers’ demands. If the quality doesn’t live up to the standards, customers won’t return and the brand might risk tarnishing its reputation. The ideal situation, of course, is not to have any problems at all. For this, buyers should conduct sufficient sourcing study before ordering to make sure they pick reliable suppliers and also hand them detailed specifications that draw specific lines between what’s acceptable and what’s not. This process is highly recommended to be conducted by a local specialist, making sure the specifications and rules are fully understood by a checked-out manufacturer. Despite all these precautions, it is not unusual for issues to crop up during the production process when idealism meets with practice. 

IPQC is Important

That’s why global businesses now attach more importance to inspections, among which in-process quality inspections are often overlooked compared to pre-shipment inspections. In fact, problems spotted during the manufacturing though IPQC(In-process Quality Control) are usually fixed more inexpensively and time-effectively than if they are caught until the production is complete. In short, pre-shipment detects defects while IPQC identifies deviations. It’s highly recommended that buyers conduct their own IPQC by your Chinese purchasing office or third-party inspection companies. This can be crucially important when it comes to customizing products, while one misunderstanding or mistake against the established routes or practice during production could be fatal to deliver the wrong product idea. During IPQC, products are inspected or examined can be fixed accordingly in time so that products made subsequently are free of these problems. What’s more, it helps to shift the control partially to the buyer’s hands, while in most cases buyers are uninitiated during the long production time.

How IPQC Works?

IPQC is usually carried out when about 20% of production is complete. It’s not recommended to run the checks too early in the production timeline while the first batch of products that come off the assembly line isn’t usually perfect specimens. Factories will need to adjust the machine or process after reviewing these pieces as part of their internal quality control checks. During IPQC, inspectors will first check if the basic specification, such as colors, dimensions, which should either be identical with samples provided before ordering or within the acceptable deviations. The process is not just to identify deviations but also to speculate on the possible issue with the assistance of the factory. For instance, even if some of the products turn out to be wrong, it’s desirable that they should be wrong by approximately the same amount in each batch. This would indicate that what happened is a system problem somewhere, which is relatively easy to fix. On the contrary, if the deviations aren’t evenly found and handicraft or quality also vary significantly, then there’s very likely something bigger going on. It sometimes reflects the factory’s incapability to implement well-defined product controls. Then getting to the bottom of the problem is crucial and also certain aspects should be paid extra attention to during pre-shipment inspections.

All in all, In-Process Quality control should be considered equally important with pre-shipment inspections. Both inspections should be done for every production cycle – never mind if it’s the first or the 100th. This will ensure consistency, which helps your business build a good reputation and loyal customer group.
