2 2 3 Innovative technology for efficient and economic production of profiles and hoses Our extruders contribute to optimize production of profiles and hoses in mono and co-extrusion. The benefits of the compact extrusion construction are particularly significant for frequent product changes. Extruder size output KG kg KG kg KG ,200 kg KG ,800 kg Benefits of compact design: Extruder including gear box, electric motor and vacuum pump are mounted on a common frame; the electrical equipment is also integrated: for easy accessibility, high mobility, small footprint, space for screw dismantling. Complete factory installation including performance check: short assembly times, low assembly costs, minimal installation work. Frequency controlled asynchrony AC motor: no brushes, no wear of brushes, no belt slip, rotation speed control via tachometer. Moveable thanks to air cushion or roller system. Hinged feed roll system for easy accessibility, service life lubrication, minimized rubber leakage. Temperature control units on mounting frame, factory-assembled, slide-out for maintenance purposes: enabling easy accessibility and fast exchangeability. Opened feed roll system Slide-out TCUs for maintenance purposes Control integrated in frame Compact extruder on air cushion Example of extruded profiles Facility for the production of profiles for the automotive industry

4 5 Degassing extruder - Compound changes without replacement of degassing screw Throttle gap 0 50 100% Material flow Gear pump extruder -

The optimal conditions for the respective rubber material can be stored in the recipe file.

3 4 5 Degassing extruder - Compound changes without replacement of degassing screw Throttle gap % Material flow Gear pump extruder - Sound expertise for cutting-edge extrusion technology The DeSO System of the degassing extruder for production of technical rubber goods allows the user to adjust the necessary pressure required for degassing directly at the throttle gap, depending on the profile and compound requirements. The screw is axially shifted and adjusted during operation, eliminating the need for screw change. The optimal conditions for the respective rubber material can be stored in the recipe file. Direction of flow Cylinder Material flow optimization Reducing material flow Moving screw towards direction of flow to a position between 100 and 0%. Gear pumps with herringbone gearing in combination with compact extruders for technical precision profile productions. Impacted only by the revolution speed, they generate an even and pulsation-free volume flow rate, which is the pre-condition for optimal profiles. Material Outlet Functioning Material flow Material Inlet Filling of the tooth gaps, transport in the tooth gaps, discharging of tooth gaps. Gear pump and profile head with clamping ring and swivelling mechanism Extruder type KGE 90/20 with DeSO system Gear pump for high accuracy requirements, with 120mm compact extruder for profile production

4 6 7 Strainer extruder Thanks to its compact design a strainer extruder can be deployed anywhere in the mixing room and for production. The gentle pre-heating in the feeding screw of the gear pump can be adjusted individually for the respective mixture. Pre and finished filter units for straining guarantee perfect product quality. The gear pump ensures precise stripe shaping without any calenders. Shear head Established technology for high-precision profiles. Especially stable process parameters can be achieved Precise temperature probe Direct drive, water-cooled Co-extrusion Extrusion heads for complex profiles of various compounds Extrusion of multicomponent profiles with or without reinforcing plies Up to four extruders can be connected Strainer extruder KG 150 / 10 + ZRP Vertical extruder Compact extruder in vertical alignment can be electrically height-adjusted can be swivelled can be coupled to co-ex heads WaCo system Wall Control system for hose extrusion Automatic wall thickness centering at extrusion head X-ray measuring system for diameter and wall thickness Hydraulic controlled wall thickness adjustment
