  • What are the functions of the injection screw head and nozzle?

    In the injection screw, the function of the screw head is to discharge the plasticized melt into the storage chamber during pre-molding, and to effectively seal the melt at the front of the screw head during high-pressure injection to prevent Backflo...

  • How to improve the production efficiency by improving the screw barrel of the injection molding machine

    The screw of the injection molding machine is an important part of the plasticization part of the injection molding machine. The quality of the screw barrel is of vital importance for improving the quality and quantity of the molded products of the i...

  • How to improve the technique of using screws

    Every plastic has an ideal plasticizing processing temperature range, and the barrel processing temperature should be controlled to be close to this temperature range. When the granular plastic enters the barrel from the hopper, it will first reach t...

  • 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 twi...

  • 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 fin...

  • 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-sc...

  • 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 als...

  • 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...

  • 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 ...

  • 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, ...

  • What are the common reasons for the screw not feeding

    In the processing of plastic products, many screw barrel for Injection molding machine questions are often encountered. One of the common questions is that the screw of the injection molding machine is not fed. This kind of question: The screw i...
