What is the production process of hydraulic hose protective sleeve

The production of the hydraulic hose protective sleeve adopts the heat setting process, which is generally divided into two types: primary setting and secondary setting.

One-time setting process: nylon or plastic granular materials are heated and plasticized by a plastic extruder and extruded into thin strips. After being cooled by cooling water and shaped, it is separated from the mandrel and formed into a spiral sheath.

Secondary molding process: Nylon or plastic granules are cooled by cooling water after being extruded into thin strips by an extruder; the cooled strips are wound on mandrels of different specifications by a winding machine; then the mandrels are pushed into the vulcanization tank Heat vulcanization. After a certain period of time, the can is out of the tank, and the mandrel can be removed to form.
