  8. Plastic Injection Molding • Plastics are melted in a heated cylinder and forced into a mold by hydraulic plunger of rotating screw. • Complex shape and good dimensional accuracy can be achieved, as in die casting. http://ma.gnu.ac.kr/vod/Plastic/Plastic_Injection_Molding.MP4 http://kr.youtube.com/watch?v=bit-D1NnfjI&NR=1 http://kr.youtube.com/watch?v=NedTUB7YQE0&feature=related
