Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.&nbsp; After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.</p>]]></description><category>Plastic Injection Mould</category><comments>http://www.plastec.org/blog/post/1.html#comment</comments><wfw:commentRss>http://www.plastec.org/blog/feed.asp?cmt=1</wfw:commentRss></item></channel></rss>
