The extrusion and expansion line consists of several components, such as:<\/h6>An extruder that melts and shapes the plastic material into a tube.
A cross-linking unit that uses an electron beam to create chemical bonds between the polymer chains, making the tube more resistant to heat, chemicals, and abrasion.
An expander that inflates the tube to a larger diameter using air or glycerin, and then cools it down to set its shape.
A tray winder that winds the expanded tube into rolls for storage or transportation.<\/h6>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
