Shaping a molded component with large surface dimensions, by in-mold coating, uses mold closing and opening actions to spread out the mat followed by injection of the coating mass for spreading out by the mold sections

摘要

To shape a molded component of large surface dimensions, by in-mold coating (IMC), a thermoplastic mat with glass fiber reinforcement is placed between the two mold half-sections of an open mold. The coating mass is injected into the mold through a hot channel, and again the mold is closed and opened a number of times to press out the mass over the mat surface. To shape a molded component of large surface dimensions, by in-mold coating (IMC), a thermoplastic mat with glass fiber reinforcement (16) is placed between the two mold half-sections (10,12) of an open mold. The mold is closed and opened a number of times to press out the mat to the required dimensions. The coating mass (18) is injected into the mold through a hot channel (14), and again the mold is closed and opened a number of times to press out the mass over the mat surface.
