  • The Stages of Injection Molding
    The Stages of Injection Molding

    Injection molding parts are widely used in many industries, but how to produce such plastic parts? Many people like plastic products but they do not know how it is produced, so now we will share the production knowledge - the stages of injection molding to the worldwide people. If you need high quality injection molding, firstly we should make high quality injection mold, also called injection tooling or injection mould, besides, we need the right injection molding machines to produce the injection molding parts, so all is clear, the stages of injection molding include: 1. Granulated or powdered thermoplastic plastic is fed from a hopper into the Injection Moulding machine. 2. The Injection Moulding machine consists of a hollow steel barrel, containing a rotating screw (Archemidial Screw). The screw carries the plastic along the barrel to the mould. Heaters surround the barrel melt the plastic as it travels along the barrel. 3. The screw is forced back as the melted plastic collects at the end of the barrel. Once enough plastic has collected a hydraulic ram pushes the screw forward injecting the plastic through a sprue into a mould cavity.  The mould is warmed before injecting and the plastic is injected quickly to prevent it from hardening before the mould is full. 4. Pressure is maintained for a short time (dwell time) to prevent the material creeping back during setting (hardening). This prevents shrinkage and hollows, therefore giving a better quality product. The moulding is left to cool before removing (ejected) from the mould. The moulding takes on the shape of the mould cavity. You will know how to produce injection molding if you read the blog, PTMS would like to learn and share more and more data of injection molding with people who like injection molding, if you need our service, please send us RFQ or send e-mail to sales@ptms-mold.com. 

  • Injection Molding Process
    Injection Molding Process

    Plastic injection molding parts is widely used in Automotive, Home Appliance, Medical, Printer, Plastic Tooling,Defense and Electronics industries. PTMS as a professional injection molding manufacturer, we would like to share injection molding process to people who are interested in injection molding. The details of injection molding process include: 1. close mould - the moving and fixed platens of the injection moulding machine hold the mould tool together under pressure. 2. injection - the molten plastic that has been melted from pellet form in the barrel of the moulding machine is injected under pressure into the mould. 3. cooling - the plastic parts are then allowed to solidify in the mould. 4. opening - the moving platen moves away from the fixed platen separating the mould tool. In the fact, the injection molding process is very interesting, the injection machines are very important for production, our company has 20 sets advanced auto injection machines for mass production. If you like to know knowledge about injection molding, welcome to send us RFQ to sales@ptms-mold.com.
