Surface finish plays a crucial role in both aesthetics and functionality of injection-molded parts.
When plastic resin is injected under pressure, it conforms to the texture of the surface it encounters. If that surface is smooth, the resulting plastic part will reflect light, creating a glossy appearance. Conversely, a rough surface scatters light in all directions, giving the surface a dull or flat look.
When you enter production, there is always a very specific need for the part you are aiming to produce. Getting the surface finish correct is of course about the aesthetics - a well-chosen surface finish enhances the perceived value and quality of a product, and it can also hide imperfections caused by the molding process, such as tool marks or flow lines - but aside from that, the right choice of finish can also impact on functionality. Having the correct surface texture affects grip, paint adhesion, and safety. For instance, textured finishes improve slip resistance and allow trapped gasses to escape during molding.
Typically characterized using a system of four grades (A to D) as set out by the Society of the Plastics Industry (SPI), making the correct choice is not always simple however. As manufacturers of injection molded parts at huge scale, and with an in-house tooling shop, ADIS Tachov s.r.o. boasts decades of hands-on experience in every aspect of plastic production, and can help guide you in the right decision making for your own specific need.
