In-Mold Coatings for Interior Automotive Plastic Components
The in-mold process allows for parts to be molded and coated in a one-step process so that finishers do not have to use multiple steps to mold and paint the part. This eliminates many plastic preparation costs (cleaning, degreasing, priming, sanding, flame treating, etc.) and uses less packing and shipping, less labor, and produces less waste, thereby generating a substantial cost savings for the finisher.
The cycle time to produce a steering wheel or instrument panel (IP) skin with an in-mold coating can range from three and a half to five minutes, depending on the mold temperature and the type of elastomer. The part and the in-mold coating are fully cured and chemically bonded to one another during the molding process, eliminating the need for bake ovens as in post-painted parts.
