Abstract

Nowadays, technology of rubber forming is being developed and is being polished for producing precision rubber products and development of related equipment. It was found that most of the rubber forming companies are small and use a conventional hot press method. This method causes a cost increase because the energy efficiency is lowered. The purpose of this study is to improve the energy efficiency by directly heating the cartridge heaters installed in the mold and proving that the mold temperature can be uniformly maintained. It was found that the sample mold required less time for temperature rise initially, more energy was saved due to the large and small temperature change, and product defect reduced due to temperature variation and improved production technology giving a uniform quality.
