Brief introduction of high quality rubber machine barrel screw manufacturer :
Single screw extruder screw types and uses: ordinary type, progressive type, sudden type, mixing type, separation type, pin type, exhaust type, barrier type, split type, wave type, acceleration type Silk, granulation, drawing, blown film, extruded header, foaming, extruded sheet, extruded board, etc.
The material of the product is made of high-quality gold-containing steel (38CrmoALA), which is precision-made by adjustable quality and qualitative, surface nitriding, polishing and other processes, and has the characteristics of precision wear resistance.
We can not only make samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair work on old screws. The service life of bimetal screws is 3-5 times longer than that of ordinary nitriding screws. .
The structure of the barrel is relatively simple. In large extruders, the barrel structure can consist of several sections. Since the barrel is divided into several sections, the length of each barrel is reduced, which brings convenience to the machining barrel. 同心度 精度比较难达到*；此外，分段机筒用法兰连接，给机筒的加热和冷却设备布置也会带来些难度，温度控制也不会太均匀。 However, the barrel diameter of this kind of barrel composed of several sections is difficult to achieve after machining, and the accuracy of the concentricity of the bores of several barrels is difficult to achieve. * In addition, the section barrels are connected by flanges to heat and The arrangement of cooling equipment will also bring some difficulties, and the temperature control will not be too uniform. 合金钢材 ，有些大型挤出机的机筒采用内孔加衬套或浇铸耐磨合金层的方法。 In order to save the more expensive alloy steel , some large extruder barrels use internal bores with bushings or cast wear-resistant alloy layers. Such a barrel outer body can be cast by ordinary steel, so as to reduce the manufacturing cost of the barrel.
