  • What is blow molding machine

    Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic blank obtained by extrusion or injection molding of thermoplastic resin is placed in the split die when it is hot (or heated to a softened state). After closing the die, compres...

  • Working principle of the suction machine

    The working principle of the suction machine is that the control device activates the motor to extract the inner air while closing the blanking apparatus, so that the burial is a negative pressure. Under negative pressure, the storage tube is sucked into the hopper through the feed tube. When the...

  • The history of the bottle blowing machine

    Enoch ferngren and William kopitke first verified the blow molding process. The principle of this process is derived from blowing glass products. In 1938, ferngren and kopitke built a bottle blower and sold it to Hartford empire. This is the beginning of the commercial blow molding process. In th...
