PVC steel wire hose is widely used in industrial and civil fields, and its manufacturing process is crucial to its quality and performance. In this article, we will discuss the molding process of PVC steel wire hose to help you understand its manufacturing process.

The basic composition of PVC steel wire hose

PVC steel wire hose is usually composed of PVC material and steel wire skeleton, PVC material provides the flexibility and durability of the hose, while the steel wire skeleton enhances the structural strength and pressure resistance of the hose.

PVC steel wire hose molding process

Material preparation

The first step in molding PVC steel wire hose is to prepare the material. This includes PVC resin, plasticizers, stabilizers and other raw materials, as well as steel wire skeleton. Ensuring the quality and ratio of materials is critical to the quality of the final product.


Extrusion is one of the key steps in the manufacture of PVC steel wire hose. In an extruder, pre-mixed PVC material is heated and extruded through a die to form the shape of the hose. At the same time, a steel wire skeleton is inserted inside the hose to reinforce the structure of the hose.

Molding and Cooling

After extrusion, the PVC hose undergoes molding and cooling steps to ensure its shape and dimensional stability. In the molding machine, the hose is shaped and cooled to maintain the desired shape and size.

Inspection and Packaging

Finally, the molded PVC steel wire hose is inspected to ensure that its quality meets standards. Qualified products will be packaged and ready for shipment.
