• Injection Mold tryout guideline

    As known, the manufacturing of plastic injection mold determines the quality of plastic molded parts, production effieciency and cost of finished products.Mold trial is run to solve any problems with the design, resin, tooling,machine. Thus procedures of mold trial is very important for a injection molder. Be sure to follow this nine-step process to make sure you’ll be making good parts through a successful trial.   Firstly, Keep the  injection mold run on the press without any resin to verify the function of  the mold    A. Check mold opening and closing condition at low pressure:   Mold should beopened and closed by 3 times at fast, medium and slow speed. During the process, there should be no abnormal sound nor block phenomenon;   Mold opening and closingshould go smooth  without any interference.   B.Checkejection system of the injection mold (at low pressure)   1.Check the ejection action at  fast, medium and slow speed.   2.Check whether ejector pins  or sleeves on the…
