Abstract: By using APG manufacturing process, the production cycle of epoxy resin products can be shortened from more than ten hours required by the traditional manufacturing method to more than ten minutes, but there are often some defects such as bubbles, shrinkage and cracks existing on the surface of products in the manufacturing process, which affect the performance and appearance of insulation products. This paper analyzed the mold design factors, researched the cause and control of defects in product working process and gave the countermeasures. It is pointed out that the mold and equipment in good condition is the important factor to guarantee insulating parts quality. In the concrete technical control process, the site instruction, the tour of inspection of workshop administrator and artisan are the first condition to ensure high quality epoxy resin products.
Key words: APG manufacturing process; mold structure; epoxy insulating part
