Maquina Extrusora de plastico/ como se hacen tubos de PVC

Welcome and Introduction

The video introduces the operation of a plastic extruder for making PVC pipes, emphasizing recycling and the production process involving recycled plastic and virgin material.

Operation of Plastic Extruder

• The production process starts with mixing raw materials in the mixing area to prepare for extrusion.

• Polyvinyl chloride (PVC) is a key material used in the extrusion process, belonging to the family of thermoplastics.

• Various additives like thermal stabilizers, lubricants, calcium carbonate, and pigments are essential for enhancing PVC properties and coloration.

Extrusion Process

This section delves into the extrusion phase where mixed materials are fed into hoppers, heated in the barrel, and shaped through an extruder head to form tubes.

Extrusion Phase Details

• Different colored pipes serve specific purposes such as white for pressure pipes and yellow for sanitary pipes.

• The extruder head plays a crucial role in determining tube diameter; changing it allows manufacturing tubes of various sizes.

Cooling Phase

Cooling is vital post-extrusion to set pipe shapes and diameters while lowering plastic temperatures.

Cooling Process Insights

• Cooling tanks with water at low temperatures fix pipe shapes, lower plastic temperatures, prevent compression, and aid in achieving desired round shapes.

Labeling and Cutting

After shaping tubes, they undergo labeling processes followed by cutting to desired lengths.
