The quality control of cloth button products is mainly divided into raw material control and process control;
1. Raw material control: We select the environmental protection raw materials that meet the final inspection standards according to the customer's requirements, such as aluminum sheet, aluminum post inspection (exported to Japan); six restricted substances that are RoHS compliant, EN71-3\ASTMF963, eight heavy metals, EU REACH regulations , US CPSIA/HR4040 Act requirements (exported to Europe and the United States); in line with brand custom standards such as Mattel 19 heavy metals, IKEA IOS, WORLD, CHANEL and other requirements (for exporting foreign brands); there is no clear test standard but requires quality to produce with the highest requirements ( Domestic first-line brand).
2. Process control: With so many undetectable inspection indicators for raw material control, process control is simpler, but simplicity does not mean it is easy. The process includes material stamping, injection molding, electroplating, fabric finishing, trimming, match-testing prior to bag-locking, buttoning, and interlocking between each process. A perfect quality cloth button not only requires specialized molds and equipment, but also requires skilled operation to ensure the quality of the finished product is qualified and stable output.
The processing control focuses on the button's tensile strength and perfect appearance. The tensile strength can not be tight and the pulling force is insufficient (see US AATCC tensile test standard or EN71-3 tensile test 90N±2N +10 seconds); the appearance can not be rot (Leather), lack of cloth (leather), thread, fabric wrinkles, dirt, uneven fabric, use of anti-cloth, positive deformation, reverse deformation, corn hand scraping, hole blocking the foot, plastic burr, plating, scratches, Different colors, unobtrusive packages, etc. can all affect the appearance of defective products.
