Performance introduction of conical twin-barrel screw Conical double barrel screw is mainly composed of three parts: gear transmission system, electrical control, barrel screw. The conical double barrel screw gear transmission system includes a gear box and a distribution box. Conical double barrel screw performance: The conical twin-barrel screw has forced extrusion, high quality, uni
How to choose the screw barrel of the granulator? The commonly used screws on the market are 45-gauge steel, 40Cr steel (chrome-plated), 38CrMoAIA nitrided steel. If your product is + glass fiber. When using chrome plating, it will slowly fall off after about 3 months, and the color difference will appear. It is best to choose Nitriding. Stainless steel screw can not be made of glass fiber. Gen
Characteristics of conical twin screw extruder Conical twin-screw barrel has stable performance, which can make the melt plasticized and extruded at a low temperature. The barrel is equipped with a cast aluminum heater, which has high thermal efficiency, fast and uniform heating, and is equipped with a cooling fan. Features of conical twin screw barrel: Conical twin screw barrel has the
In the production process of extrusion processing, the screw of the extruder will make a noise when it rubs against the inner wall of the barrel.The reasons for this friction phenomenon are nothing more than the following four reasons: 1. The assembly gap between the screw of the extruder and its supporting transmission shaft is too large, and the center lines of the two shafts are not conce
How to reduce wear and improve the use technology of screw and barrel? The screw is operated under high temperature, high pressure, high mechanical torque and high friction environment for a long time. The first few factors are required by the process conditions, and the loss caused by friction is inevitable. Generally, the screw has undergone surface nitriding treatment to improve the surfac
Why does the barrel screw of single screw extruder wear out? As a common extruder equipment, single screw extruder is used in plastic processing industry, such as blown film, platen, extruded tube, ribbon pulling, etc. It can also be used for melt granulation. Many people will encounter the wear of the barrel screw during use. What causes this? The diameter gap between the single screw extr
Introduction of the characteristics of double alloy barrel screw Double alloy barrel screw is wear-resistant, high-temperature resistant and corrosion-resistant. It adopts a unique process and the alloy layer is inlaid firmly without falling off. Characteristics of double alloy barrel screw: 1. The double-alloy barrel screw has the ability of fast check speed; 2. Complete anti-re
Quality requirements for making barrel screws A screw barrel must first be able to produce products that meet the quality requirements. The so-called screw barrel quality requirements mean that the products produced should meet the following requirements: 1. Various performances that meet the requirements. Have physical, chemical, mechanical, and electrical properties that meet the re
