There are many requirements for the material of the injection screw, which we have introduced before. The color difference is a common defect in the screw of an injection molding machine. There are many factors that affect the color difference, invol...
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...
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...
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...
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...
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...
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...
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...
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 ...
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...
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 ...
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, ...
