  To those less familiar, plastic Injection molding might be understood to be a producing process for creating products from plastic materials. The plastic is fed in to a heated barrel, mixed, and compelled into a mold cavity where it loses heat and solidifies to the configuration with the mold cavity.

    Plastic injection molding industry has had a fascinating history. Plastic material was invented in great britain in 1861 by Alexander Parkes and the man called the material as Parkesine. People found Parkesine to get extremely useful that it could be heated, molded, making to retain its shape when cooled. In 1868, American inventor John Wesley Hyatt developed a plastic-type material he called Celluloid that has been a marked improvement over Parkesine' as it may be processed into finished form.

    In reference to his brother Isaiah, Hyatt patented the first machine in 1872. This machine was however too simplistic when compared to the machines trusted today. The present day machines consist of a material hopper, a shot ram or screw-type plunger, plus a heating unit. Also, some advanced machines have built-in sampling and approval process for stringent qc.
