Toughened Engineering Plastic The core-shell polymer particles are composite particles having a double layer or a multilayer structure composed of components having different chemical compositions or different aggregated forms. In 1957, Rohm & Haas of the United States first developed a core-shell polymer of the trade name K120. In the 1960s and 1970s, companies such…
Advantages Of Multi-Component Injection Molding In multi-component injection molding, the components of the molded part are completely separated. All components are visible on the surface, reflecting the appearance and function of the part. For example, keyboard buttons, labeled switches, or handles with soft areas for added comfort. In addition to the ability to produce injection…
Two-Station Mold In order to demold the part independently of the production process, a stripping station was integrated into the two-component molding. The mold is then rotated clockwise in steps of 120°. There is an opening on the side of the third station from which the gripper gripper can reach the closed mold, demold the…
Four-Station Mold Multi-layer plastic parts can be produced using four-station molds. This method is easy to implement when using recycled materials and barrier layers. The innermost layer is produced at the first station. Then, the mold is rotated 90° to the next station. At this time, the first component was injection molded using the second…
