New technology for nylon slider
From:admin Time:2018/7/24 21:44:05

Nylon slider manufacturing and forming methods are also diverse. It not only uses static casting polymerization to form round bars and block parts, but also uses dynamic centrifugal casting polymerization to form tubes, tubes, wheels, etc., and can also manufacture various hollow containers and shaped products by means of biaxial rotary casting polymerization. Such as fuel tanks. In recent years, a technique of direct continuous polymerization molding in a twin-screw extruder has been developed to prepare various products, that is, a so-called reactive processing method. In the early 1980s, the reaction molding technology of nylon sliders appeared, and the extension of the manufacturing technology of nylon sliders was adapted to the need for nylon sliders for continuous mass production.
