Abstract: The present invention provides a tip molding apparatus for forming a three layered plastic part. The apparatus of the invention includes a conveyor for transporting a mold half through the tip molding apparatus; an oven for heating the mold half, wherein the conveyor transports the mold half through the oven; a skin resin loader that introduces a first powdered skin resin into the mold half after the mold half exits the oven; and at least one mold inverter that inverts the male mold half by a sufficient amount to pour out any first powder resin not adhered to the first mold half. Additionally, sections of the tip molding apparatus may further include a foam resin loader that introduces a foam resin into the mold half. A method of forming a three layer plastic part by the method of the invention is also provided.

Abstract: The present invention disclosed a skin resin suitable for forming plastic skin layers by tip molding processes. This skin resin comprises a plastic resin and an antioxidant. The disclosed resin is characterized as having an average particle size, bulk density, melt index, and pourability properties which make the resin particularly useful in tip molding. A foam resin suitable to be adhered to a skin layer is also disclosed. A method for forming plastic parts using the skin resin and foam resin of the present invention is provided.
