The production of PVC (polyvinyl chloride) hose usually involves multiple steps, including raw material preparation, extrusion molding, cooling, cutting and packaging. The following is the general PVC hose production process:

Raw material preparation:

PVC resin: The main component of PVC hose is PVC resin, which is made by the reaction of ethylene and chlorine.

Additives: Resins usually require the addition of additives such as stabilizers, lubricants and pigments to improve the performance and color of PVC.

Mixing and Preparation:

PVC resin and additives are mixed together to form a homogeneous mixture.

Extrusion molding:

The mixture is passed through an extruder, which includes a screw that heats the mixture and extrudes it to form a pipe of the desired shape.

In the extruder, the mixture is subjected to high pressure and temperature to ensure complete melting and uniform pipe formation.

cool down:

The extruded PVC pipe is passed through a cooling system, usually a water bath, to quickly reduce the temperature so that the PVC pipe solidifies and maintains its shape.

Cutting:

PVC pipes are cut in appropriate lengths to obtain the required product size.

Inspection and Quality Control:

Cut PVC pipes are usually inspected to ensure that their quality meets specified standards.

This may include checking the size, wall thickness, color and appearance of the pipes, etc.

Printing and marking (optional):

If required, PVC hose may be printed or marked to include information such as brand, specification, production date, etc.

Package:

PVC hose is packaged in rolls or rolls for easy storage and shipping.

These steps are the general process of PVC hose production. Note that specific production processes may vary depending on manufacturer requirements and product specifications. In addition, quality control of PVC hoses is crucial to ensure their durability, durability and compliance with relevant safety and environmental standards.
