PROCESSING METHOD FOR IN-MOLD COATING INTEGRATIVE SYSTEM

WIPO Patent Application WO/2010/108455

A1

A processing method for in-mold coating integrative system is used in cooperation with an injection molding machine (10). The injection molding machine (10) comprises a rotatable work platform (11) and a combination of at least one male mold (20) and at least two female molds (30,50,80). The rotatable work platform (11) is divided averagely into several work areas (111,112,113,114), and the processing proceeds sequentially in each work area (111,112,113,114) by the rotation of the rotatable work platform (11). The processing method comprises following steps: injection molding a solid workpiece (40) firstly, and leaving the solid workpiece on the male mold (20); rotating the rotatable work platform (11); performing surface coloring; rotating the rotatable work platform (11); injecting UV top-coat, wherein the top-coat female mold (80) is made of light-directing material and has a die cavity (81) and a UV paint cavity (82) on the surface of the solid workpiece (40), and a UV top-coat layer (90) is injected into the UV paint cavity (82) through a paint channel (83); irradiating the UV top-coat layer by a UV top-coat hardening lamp (800); and demolding to achieve a finished product finally. The method is benefit for mass production, and can reduce labor cost and processing cost.
