Advantages Of Multi-Component Injection Molding

- Oct 17, 2018-

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 molded parts of multiple colors or materials in one process, the need for additional assembly or subsequent processing, continuous improvement in molding technology can also lead to continued growth. Injection molded parts are resistant to external influences such as mechanical, thermal or chemical effects, and are achieved by a suitable combination of materials and high bond strength.


The adhesion of the two component bonding surface can be achieved by chemical bonding or mechanical linking. If chemically compatible materials are used, permanent molecular bonding can also be achieved by a melting or welding process. The types of mechanical links range from fiberglass that can be fixed on the surface to solid connecting elements (such as holes and undercuts) on the part.


In terms of processing technology, the ARBURG ALLROUNDER modular design enables a relatively wide range of manufacturing processes. Includes soft and hard composite parts with TPE or LSR, sandwich or composite parts, or surface color repeatable parts made with an alternating injection molding process.
