1 material injection insert technology ( 注射成型钩) Applicable to all types of injection molding in the hook body, can be used in a series of thermoplastic materials, such as: pp, PE, pom, nylon, thermoplastic elastomer and so on. The technology in 2003 by French APLIX company first invented and used in production. By 2007, the company made three invention patents [in the United States 3 - 5] 。 2 principle of injection molding technology insertion replication technology is not a model, but will hook surface and the plastic parts ( Or metal parts) Of the surface of the unity of the injection molding method, hook the hook is in the insert molding. In the process of stripping, hook temporarily be straight; The cooling process, the hook experience slowly getting back to its original shape. The implementation of the method is to insert the plastic insert technology ( The parts need sticky strap) On the injection mould, With a hook shape steel sheet) , when the ejection Angle is greater than 45 °, using chute or moving of the water wheel. This can make the injection molding process operation stability, can produce millions of pieces of hook surface without special maintenance. Injection into the use of technology to further broaden the fastening belt area, changed the sticky strap on a smooth surface when using need to put glue on the back, strengthened the fastening tape stripping resistance
