The 16-32mm PVC threading pipe produced by Qingdao Cuishi Plastic Machinery has one output and four production lines. This machine is used for extrusion molding of pipe production lines. , measurement, into the molding die.

The material of the barrel and screw of this machine is all 38CrMoAlA, which has been forged, quenched and tempered, twice aging treatment, and nitriding treatment. The difference from other manufacturers is that the screw thread is quenched and tempered after rough machining, the material has excellent hardenability, and the effective stress is obtained after two aging treatments. At the same time, the processing is excellent, and the phase error of each flight of the screw is small.

The barrel and the screw are interchangeable. For different materials, the screw structure is all changes. The reduction box distribution box is composed of hard-surface gears, with high precision and anti-fatigue.

The material of the gear box gear is 20CrMnTiA, which has been carburized, and the material of the helical gear of the distribution box is 38CrMoAlA, which is processed by CNC gear hobbing machine and processed by nitriding.
