Extrusion International 5-2019

71 Extrusion International 5/2019 Since more than 125 years, TROESTER stands for out- standing quality Made-in-Germany when it comes to developing and manufacturing innovative and reliable machines for the rubber industry. In the world of rubber and plastics processing, TROESTER is known for its flexible responses to customers’ requirements and collaborates with them to produce high-quality, tailor-made solutions. Process and manufacturing specialists will be on hand to talk to stand visitors about the latest developments in de- tail. One of the products TROESTER will be presenting is a 90 mm compact extruder and a cross head that centres automatically for making hoses in superior quality. This machine has already gained a firm footing on the market and was the basis for TROESTER’s latest development: the automatic centering double crosshead. The double cross- head allows the production of two layers simultaneously, each centred by servo-hydraulic systems that operate in- dependently. Combined with a SIKORA X-ray machine, the system automatically regulates the centricity of the layer(s). To complete the portfolio for hose production equip- ment, a straight extruder head was developed which also centres automatically. From now on, TROESTER custom- ers can choose between automatically centering straight heads, crossheads and double crossheads to improve the quality of their production and products. Further benefits this new technology entails are material efficiencies, bet- ter product tolerances and quicker set-up times. As a member of the TROESTER Group, X-Compound will also be on the stand to present its kneading technology for uninterrupted production of HFFR, PVC or XLPE com- pounds. The Swiss subsidiary specialises in planning and constructing machinery for processing plastics which in- volves steps such as conveying, melting, dispersing, mix- ing and degassing.
