How to Maintain Consistency Between Approved Samples and Mass Production

For an OEM diaper project, sample approval is an important milestone before mass production. After approval, the factory prepares raw materials according to the confirmed structure, materials, and performance requirements, then arranges production, inspection, and packaging. Throughout mass production, raw material checks, online inspection, QC sampling, laboratory testing, and pre-shipment inspection help maintain consistency between the approved sample and the finished order.

After sample approval, the factory prepares raw materials according to the confirmed product structure, size, material configuration, and performance requirements. Materials such as nonwoven fabric, SAP, fluff pulp, back sheet, and elastic materials must be carefully matched according to the product design and inspected before production. The stability and quality of raw materials directly affect the final product performance, making material control an essential foundation for consistent mass production.

Once production begins, online machine inspection and QC sampling work together throughout the manufacturing process. Production equipment continuously monitors product quality through inspection systems, including stain detection, electronic eye inspection, and metal detection. These systems help identify abnormal products during production and remove them in time. At the same time, QC inspectors conduct regular checks on product appearance, dimensions, structure, and key requirements according to production standards. The combination of automated inspection and manual quality control helps improve production stability.

In addition to online inspection and QC checks during production, finished products are further evaluated through laboratory testing based on the product requirements. Jiayue’s standard testing includes absorption performance, rewet, dimensions, elasticity, and leakage performance. Through these tests, the actual performance of mass-produced products can be verified and compared with the requirements confirmed during the sample approval stage.

Before shipment, Jiayue conducts a final inspection to confirm the overall condition of finished products. The inspection covers packaging appearance, printing quality, alignment accuracy, sealing condition, and any potential issues such as damage or poor bonding. This final quality check ensures that products are delivered in proper condition before entering the transportation process.

From sample approval and raw material inspection to production monitoring, laboratory testing, and pre-shipment inspection, OEM diaper quality control is a continuous mass-production process rather than a single checkpoint. Jiayue applies the confirmed product specifications and order requirements at key stages before, during, and after production, providing a stable manufacturing foundation for baby diaper and adult diaper OEM orders in different markets.
