Introduction of double layer pipe extrusion machine






1. the machine is used to produce double color, double layer pipes in two different materials by co-extrusion;
2. Applied materials: PE, PP, PS, ABS, PET, PC, POM, PMMA, PVC, EVA etc two different materials;
3. Features and advantages:
(1) Give full play to special solidity of various plastic materials, so that they play the leading role in the composite materials;
(2) Integral technology combining many materials for forming together, no need bonding or sticking, high efficient, low cost;
(3) Rigid and soft materials composited together, strong and flexible in one body;
(4) Porous and dense materials composited together to get light quality, high strength ratio material with specific performance;
(5) Could produce various pipes, profiles in multi-kinds, new variety, excellent-performance, to meet use in special conditions;
(6) Material of screw and barrel:
High strength nitrogenization treatment alloy steel (38CrMoALA) or quenched alloy steel (9Cr18MoV);
(7) Screw L/D: 20~38; according to material and product feature;
(8) Main motor drive: imported frequency converter or imported servo motor;
Imported double digital display PID adjusting digital type temperature controller;
(9) Barrel: 4 zone heating & forced wind cooling, could use brass material heat radiation piece according to material feature to ensure radiation effect.
