• How to choose your next Extruder

    Extruders can be thought of as high temperature short time cooking  equipment, that can transform various raw ingredients by forcing through a die to create the desired final product shape during new product development in Parallel twin screw barrel ...

  • How the extruder barrel and screw are composed

    Extrusion is a manufacturing process used Extruder screw barrel to shape molten plastic. Internal friction and an external heat supply by way of heat resistors are exploited to transform an infed base material into a finished or semi-finished product...

  • How does a twin screw extruder work

    The purpose of the extrusion process is Conical twin screw barrel to continuously change the physico-chemical viscous polymer medium and produce high-quality structured products by precisely controlling the processing conditions.The twin-screw extrud...

  • What is the effect of the screw and barrel size being too big

    Note the oversizing of screws and barrels is generally single screw barrel only done for extrusion and blow molding applications and very seldom done for injection molding. That’s because in injection molding the non-return valve would also have to m...

  • What is the role of the extruder screw of the plastic machine

    The material of the Conical twin screw barrel must have high mechanical strength, be able to withstand huge torque, and have the performance not to deform under high temperature and high pressure conditions. The rotation of the extruder screw in the ...

  • How to avoid screw cross contamination

    Although purge compounds are designed Nitriding screw barrel to leave much less residue, it is inevitable that there will always be some residue of a previous product left inside the machine.There are some ways to overcome this. One method is to use ...

  • How to properly maintain the conical twin screw extruder

    1.When the new machine is used for half a year, due Parallel twin screw barrel to the wear and tear, we must check the clearance between the screw and the barrel every three months, and make appropriate adjustments. This should be done to avoid an ex...

  • What is the effect of oversized screw and barrel

    Note the oversizing of screws and barrels is generally only done for extrusion and blow molding applications and very seldom done for injection molding. That’s because in injection molding the non-return valve would also have to made oversize, which ...
