ROTO-FRICTION INSERTION

Insertion of inserts into plastics by means of friction-generated heat.

ROTO-FRICTION INSERTION

The roto-friction technique, generally used for the welding, can as well be used to insert components into articles of thermoplastic material. What is actually obtained is a kind of welding between component and insert.

Article and insert are in contact from the beginning of the process. The rotational movement and the pressure applied to the insert cause friction on the article. The heat generated by the friction makes the material flexible – it then envelopes the outer profiles of the insert. During the last phase of cooling, the inserts are still subject to pressure until the fixation is stable.

Insertion by roto-friction can be applied to articles produced by means of injection moulding, extrusion moulding, compression moulding, thermoforming, blow moulding, suction 2D/3D (2k) and rotational moulding.

Among the articles into which components have been roto-friction inserted by the customized machines of GS Finishing Machines there are the following, listed as an example: battery boxes, automotive pedalboards, supports for the steering column, filter boxes, tanks, pipes, conveyor ducts, light cases and accessory components of any nature.
