Development of Wasteless Mold for rubber molding Part

고무 성형제품의 Wasteless 금형 개발에 대한 연구

The application of rubber produt is a quite extensive field and has several problems in point of mass-production. The inhibitive factors at the general rubber mold are occurrence of flash, loss of raw material by curing for sprue and runner, environmental pollution by scrap junked after extraction of product and the unavailable mold structure for automation. The existence of flash at the rubber mold requires extra-process for removing or finishing it. As the reason, we can't help avoiding deterioration of quality and rising of cost. Hence we promptly need to research fur the efficient structure of mold and the preventive transforming technique of the flash without any loss of raw material in advance. This monograph is a study for Wasteless rubber mold that give us a solution for several problems happened at the general rubber mold.
