A spiral sheathing machine is a specialized piece of equipment used to produce spiral sheathed tubing. Its core function is to process plastic raw materials such as polypropylene (PP), polyethylene (PE), or nylon (PA) into spiral-shaped protective tubing through a hot-winding and shaping extrusion process.
A spiral sheathing machine typically consists of a plastic extruder, a molding machine, and a cooling water tank. Its workflow includes: heating and plasticizing plastic granules, extruding them into thin strips, then spirally winding them onto a mandrel, followed by cooling and shaping to ultimately form a spiral sheath with elasticity and binding force.
The finished products produced by this machine are primarily used to replace traditional metal springs, providing wear-resistant, anti-aging, corrosion-resistant, and UV-resistant external protection for internal components such as hydraulic hoses, electrical cables, and water pipes, thereby extending their service life by more than 3 years. This equipment is widely used in engineering machinery, mining equipment, charging piles, and power facilities.
