Technical parameters of alloy screw barrel Technical parameters of alloy screw barrel: Processing range: inner diameter Ф20mm-Ф250mm; Effective length: 8000mm; Alloy composition: 88wc/12c0.Crc/25Nicr.XaloY108; Alloy hardness: HRC60°-65°; Surface roughness: R0.4; Screw straightness: 0.015mm; Scope of application: It is suitable for all kinds of spe
Advantages of double alloy barrel screw The double alloy barrel screw is a layer of 1-2mm wear-resistant, corrosion-resistant, high-temperature resistant alloy spray-welded on the inner wall of the barrel. Its effective service life is greatly improved compared with ordinary nitride barrels. It is a high formula for processing PVC calcium powder. , Increase the wear life, the superiority of bim
Advantages of screw and barrel of film blowing machine The screw section of the film blowing machine is a screw groove with a fixed groove depth. In addition to its main functions of mixing, melt output and measurement, it must also provide sufficient pressure to maintain a uniform temperature of the melt and stabilize the flow rate of the molten plastic. If it is long, the mixing effect is goo
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
