Injection Molding PROCESS

Use of goods made of plastic from time to time shows rapid growth, widespread almost all sectors of human life such as the use for: equipment and household goods including clothing and equipment for cosmetics, equipment and office supplies, facilities in education, building , transformation, electrical and electronic equipment, automotive, aircraft, agriculture and fisheries sector and many other uses. This is because plastic has the ability to substitute materials made from wood, metals, rubber, leather, glass and others. Along premises developments use plastic, plastic industry and the development of processing facilities has grown rapidly plastikpun. In the processing of plastic into a plastic goods known to have some type of plastic processing machines like: thermoforming, Extrusion, blowmolding, injection molding, tubes and more. From a group of plastic processing machines may be grouped based on the work process that is continually working engine and machine work cycle, including injection molding machine that processes at work in cycles. Injection molding machine has the function to change the plastic material of the form of granules [plastic seed] or puder into plastic goods that have a shape. Of the many plastic products represents nearly 80% of plastic products. The process is a plastic material in the form of granules or puder was heated to be melted, then injected with the aid of screw drive plunger into the hollow mold and cooled, then frozen plastic Limer. Hardened and shaped according to the shape of the cavity, the last product released. Step-by-step process is called a cycle, ie the process step to the original will always be repeated when the one-step operation is completed. The quality of the results of the process [product] will depend on engine operating conditions, the quality of processed materials mold / molds and conditions of the machine itself, where the condition of the engine would be better if all the components or parts of machinery and mold works well and balanced. Process injection molding machine a) Matter is closed and restrained, the material has been injected into the mold / mold. b) Screw moved back, a replacement of down and get into the cylinder and collected in the space in front of the cylinder. c) The result of the process (product) in the remove from the mold / molds.
