Ripstaal Extrusion BV is a leading producer of plastic profiles. Extrusion is a collective term for a production method in which plastic granulate is pressed through a mould. Before being pressed, the granulate is heated to a homogeneous mass. Extrusion is a continuous process. The mould contains one or more more more more or less complex shaped holes, which eventually give the profile its shape. When the molten material is pressed through the mould, it has assumed the shape of the desired profile. The profile is then transported by a pulling unit and cooled with water and air. It is possible to provide profiles with punched holes, single or double-sided tape, etc.
