INSULATED STAMPER CORE FOR INJECTION MOULDING OF LARGE SURFACE PRODUCT

摘要

PURPOSE: An insulated stamper core for injection molding of a large surface product is provided to spray and coat a ceramic material having low conductivity on a thin plate metallic pattern layer where minute patterns are formed so that an insulating layer of the ceramic material can be coated and an insulating effect is high. CONSTITUTION: An insulated stamper core for injection molding of a large surface product comprises a core body(14), a thermostable adhesive layer(13), and a pattern layer(11). The thermostable adhesive layer is spread on a top surface of the core body. The pattern layer is arranged in the upper part of the thermostable adhesive layer. Minute patterns are formed in the upper surface of the pattern layer. An insulating layer is disposed between the pattern layer and the adhesive layer. The insulating layer is formed throughout a whole lower surface of the pattern layer. The insulating layer is formed with insulating materials inserted into the inside of grooves formed in the lower part of the pattern layer.
