Abstract

우레탄, 에폭시, F,R,P 같은 재료는 사출성형이 불가능 하므로 치구에 액체를 부어 굳혀서 만들어야 하므로 복잡한 공정과 제조비용이 많이 들므로 단점을 보완하기 위하여 사출 성형 방법을 발명하였는데 제조 방법으로 먼저 열가소성 수지에 경탄을 혼합하여 적당한 비중과 강도를 맞춘다.Materials such as urethane, epoxy, F, R, and P cannot be injection molded, so they must be made by pouring liquid into the jig, which requires complicated processes and manufacturing costs. Mix hardwood with resin to achieve proper specific gravity and strength.

수축을 방지하기 위하여 금형을 두개를 제작하여 두번 사출하는데 먼저 속구를 금형에 사출하여 굳힌후 겉구슬 금형에 넣어 중앙에 고정시킨후 사출하여 굳힌다. 완전히 굳은 제품은 겉표면을 사포로 연마한다.In order to prevent shrinkage, two molds are produced and injected twice. First, the fastener is injected into the mold and hardened. Completely hardened product is sanded on the surface.
