Principle of Thermal Separation • Two-part shaft for good thermal separation between nozzle and mold insert • Low heat flow into the cavity • Constant temperature control in the nozzle • High leak tightness between nozzle and mold insert GÜNTHER Hot Runner Technology for Medical Engineering Applications • Development of custom tailored solutions in close cooperation with our customers • On-line system configuration with the CADHOC system designer • Externally heated systems guarantee optimal melt flow with low pressure drop • Hot runner systems for the most varied demands • Two-part shaft for optimal thermal separation (patented) • Modular nozzle design • “Hot half” as a ready-to-install mold half Hot Runner Systems for Medical Engineering Technology For more information on our services and products, please check out our website at www.guenther-hotrunner.com GÜNTHER Heisskanaltechnik GmbH Sachsenberger Straße 1 D-35066 Frankenberg Phone +49 (0)6451 5008-0 Fax +49 (0)6451 5008-59 info@guenther-heisskanal.de www.guenther-hotrunner.com Cover: Production line for producing and bottling infusion solutions. A special closure is placed on the filled bottle and subsequently overmolded with PE. This application uses a modular valve gate hot runner system from GÜNTHER. Photo: B. Braun, GÜNTHER Valve Gate Technology Valve gate technology offers clear benefits including: • superior surface finish in the gate area • high process reliability • low shear rate of the melt to reduce orientation and residual stress of the part Valve gate technology takes advantage of a modular nozzle design. Narrow pitches are possible. One can choose between different types of needle actuation: single valve gate nozzle or, in multiple systems, single needle valve, lifting plate or sliding plate mechanism. The needle can be adjusted from the outside without mold disassembly. A wear-resistant needle guide made of PM steel guarantees long service life. Various gate diameters are possible without refinishing the inserts.

Innovative Pace setting developments in medical engineering are closely connected with plastic materials.
