Plastic pre-stressed bellows production equipment available

A press machine capable of producing pre-stressed plastic bellows was successfully developed by Qingdao Fenglida Plastic Machinery Co., Ltd. a few days ago.

The new production line is equipped with a special separation type mixing screw and screw structure head, with features such as high-speed extrusion, high-speed plasticization, etc., which can make the inner and outer walls of the pipe smooth. The pre-stressed plastic corrugated pipe produced by it overcomes the disadvantages of the traditional galvanized corrugated pipe, such as water leakage, short service life, rust, conductivity, etc., has good corrosion resistance, is non-conductive, can prevent stray current corrosion, and has good sealing performance. Does not rust. In addition, the product has high strength and rigidity, good impact resistance, and is not afraid of pressing. It can reduce the friction loss of the prestress in the tension process and can be widely used in highway overpasses, viaducts, and railway bridges. The unit can also produce PP, PE and carbon spiral pipe after replacing the mold.
