1. When the new machine is used for half a year, due 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 excessive clearance which could cause a decline in production output, and could even be the result of the large angle of the screw swing leading to a broken screw. 2. The...

1. Firstly, heating the connection of Single Screw Barrel and the head of the storage cylinder above to normal process temperature. The plastic material in the barrel is basically extruded clean. Then remove the bolt of connection, heater, and connection wiring. Remove the cooling water pipe of the feeding section, automatic feeding device, the motor, and connection wiring of the extruder. 2....

With the fast paced cycles, RPMs, and back pressures that certain process engineers can run, premature wear on the cylinder walls of an injection molding barrel can become one of the biggest reasons inconsistent shots or the inability to hold cushion to occur. In a vast amount of instances we have been able to save the customer money by just measuring the stroke end of the barrel and know that...

At its core, the extruder is a very simple machine. The various configurations of shaft speed, number of chambers and types of Injection Molding Screw Barrel enables the operator to create a multitude of products. Different products usually require different configurations and run parameters. An important parameter to consider is retention time in the Extrusion Screw Barrel. Depending on what...

The single screw extruder from Single Screw Extruder Screw Barrel Manufacturer is the workhorse for many extrusion processors. It is relied upon daily to keep pumping out the extruded plastic products. They lead the way for those on time shipments to meet your hard-earned customer demand. Therefore, it is important for extrusion processors to consider and maintain their extruder’s...

The screw of the injection molding machine is operated under high temperature, high pressure, high mechanical torque and high friction for a long time. The first few factors are the process conditions, and the wear caused by friction is inevitable. Generally, the Injection Molding Screw Barrel has been subjected to a surface nitriding treatment to improve the surface hardness, that is, to...

Q After you replace the Conical Screw Barrel, there is weird noise from the screw, what’s the reason? A. The clearance between screw and barrel is not proper. The screw may have been installed out of line and rubbed against the barrel. We advise you to check the installation of the screw barrel.In the case of old extruder, because of the out of shape extruder body frame, the large side...

As a plastic pipe manufacturer, saving costs in the production process is the top priority. However, in the final analysis, your products are as good as the machines that produce them. Therefore, investing in a machine composed of high-quality components should be a breeze. Many plastic pipe manufacturers often wonder why it is important to have an extruder with Bimetallic Screw Barrel and...
