TROESTER Hose Extrusion Head with Hydraulic Tool Adjustment

The demands on the manufacture of hoses, particularly in the automotive field, are steadily increasing. Besides the material selection and the manufacturing process, a uniform wall thickness distribution over the whole hose circumference represents an essential quality criterion.

Based on the comprehensive know-how from the manufacture of high-quality extrusion heads for the cable industry and many years of experience in the manufacture of hose lines, TROESTER presents a new system for the automatic wall thickness centering for the hose production. The main item of the new system is a cross head optimized for the hose production. The head is provided with a conventional manual die piece adjustment by screws in the front area and additionally allows for a very sensitive swivelling of the inner tolls (mandrel tip, extrusion mandrel) by means of a hydraulic drive. Contrary to well-known solutions where considerable force has to be applied hydraulically onto the outer tooling (die piece), the new design offers the possibility to position the mandrel tip in a radial direction relatively smoothly and with highest precision. As the hydraulic drive is postioned on the rear side of the head being averted from the compound output, a safe mechanical functioning of the adjusting unit is ensured even in the rough daily production routine.
