The core technology of PVC hose machines involves plasticizing and mixing PVC resin and additives using a twin-screw extruder, extruding the preform through a die, and then cooling, shaping, drawing, and cutting to complete the production process.
The core technology of PVC hose machines lies in the extrusion molding process. This process uses the rotation of the screw and the heating system to heat the PVC raw material to a molten state inside the barrel. The molten PVC is then extruded through the die in the die head to form a continuous tubular product. During extrusion, a cooling system rapidly cools the extruded hose to fix its shape and enhance its physical properties.
