  • How Does Injection Molding Work?
    How Does Injection Molding Work?

    Plastic parts are widely used in many aspects, because it’s very easy to use and very safely and comfortable for people’s life, so plastic injection molding is very important for producing plastic parts, but just a little people know injection molding work, most do not know it, because just people who work in injection molding industry know it, so we will sharing this to you.   Material for the part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cures and hardens to the configuration of the cavity. Moulds are typically made from metal, usually either steel or aluminium, and precision-machined to form the features of the part. They may need to split in a variety of ways to eject the finished part, or locate inserts that are bonded into the product. Most elastomeric thermoset polymers can be injection moulded, although custom compounding may be required in order to facilitate the process. Since 1995, looking across the entire range of thermoplastics, resins and thermoset types, the total number of available materials for injection moulding has increased dramatically at a rate of 750 per year. There were already approximately 18,000 materials available when that trend began, and injection moulding remains one of the most useful industrial processes ever invented.   PTMS as a professional plastic injection mold company in china, always provide customers custom plastic injection mold and custom injection molding, for more visit ptms-mold.com, PTMS would like to sharing other injection molding issue to people who are interested in plastic injection moulding, please give us feedback to sales@ptms-mold.com of some issue.
