Extrusion of PVC profile: features and benefits

Extrusion of PVC profile: features and benefits

For the extrusion of a profile from polyvinyl chloride, special units are used, through which a large volume of raw materials can be successfully processed.

Today there are many different techniques and technologies used to process polymers and PVC. But among the presented methods, the extrusion of pvc profiles stands out. A distinctive feature of this technology is the preliminary melting of the raw material and its forcing through a prepared hole.

Characteristics

For the extrusion of a profile from polyvinyl chloride, special units (extruders) are used, through which a fairly large volume of raw materials can be successfully processed.

It is possible to process by means of extruders not only polyvinyl chloride, but also the following types of raw materials:

  • Impact resistant plastic.
  • Polypropylene.
  • Nylon.
  • High quality elastomer.

The main advantages of extrusion technology

Extrusion of a PVC profile consists of several key stages:

  1. Pre-selection and preparation of raw materials. For these purposes, professionals use powdered, granular or granular polymers. The type of polymer is determined individually.
  2. Recycling. The selected raw materials are fed by means of special mechanisms into an extruder or into a screw-type press. The raw material prepared and loaded into the heating cylinder is exposed to a certain temperature. As a result, a special viscous consistency is formed.
  3. Profile making. The pre-prepared raw material is passed through the corresponding hole, which is part of the forming head.

As soon as the products are prepared, they are cut by means of a special tool into profiles of a certain length. Finished products are packed by means of a film or placed in containers.

What kind of equipment is used for extrusion of PVC profile?

The production line required for extrusion includes equipment such as an extruder. But to achieve the desired result, such additional units and elements are introduced into the composition:

  • Pull-type take-up rollers.
  • Saws that differ in shape and size.
  • Calibration apparatus used for cooling.
  • Vacuum pump.
  • Profile packing equipment.
  • Additional units and devices by means of which the materials are laid and packed.

To ensure the efficient operation of the production line, automation should be installed. This will improve the efficiency of the tasks assigned.
