Extrusion Process

Ensinger’s semi-finished products and profiles are mainly manufactured using the extrusion production process, which produces continuous plastic shapes in high volumes. Extruding plastic material also allows for additives or colorants to be added to enhance the materials properties to make it more specific for its desired application.

The material resin is plastified in a heated cylinder and the final shape is achieved through a specific tool.

The process begins with preparing the granule (compounding) before it is delivered, conveyed, melted and homogenisation takes place. This then ultimately forms the semi-finished part/profile in the mould. Behind the mould, guidance calibration and take-off of the semi finished shapes occur before the cooling process. The product is then cut and marked to finalize its production.

Ensinger extrudes its thermoplastic semi finished products in rod (in various diameters), sheet (with different widths and thicknesses) and tube (with different outside and inside diameters) forms. Many of Ensinger’s product range are manufactured in this way including high performance materials such as TECAPEEK (PEEK), TECATRON (PPS) and TECAPEI (Ultem®), as well as engineering grade products such as TECAMID (Nylon), TECAFORM (Acetal) and TECAPET (Polyester). The extrusion process is an efficient way to produce semi finished products with high wall thickness and dimensions.

Ensinger’s profiles are also extruded with tight tolerances in different shapes. Profiles made through the extrusion process include rods with very small diameters, different standard profiles and customer specific profiles.

It is extremely important to Ensinger’s strategy to continuously invest in production technology and in the training of its employees. We are therefore able to unite a varied range of production methods with the latest engineering processes under one umbrella.
