In addition to strand pelletizing, ips Intelligent Pelletizing Solutions GmbH & Co. KG has also established a solid standing in the market with underwater pelletizing systems. Since the launch of this type of system in 2016, ips has already sold some of ips-UWG 75 S underwater pelletizing systems. Now the first ips-UWG 120 S system for throughputs of up to 2,500 kg/h is to be commissioned at the premises of an extrusion profile producer in Italy. The company manufactures most of the materials required for its production internally. Among other things, these include the appropriate compound for the production of pipework systems. In future, this will be manufactured using an unterwater pelletizing system ips-UWG 120 S.

In this work a new laboratory test equipment is presented, that allows for the definition of suitable load conditions (force, rotational speed, impact incidence). The Instrumented Chip & Cut Analyzer (ICCA) collects all relevant data during the test. Using a mathematical algorithm, realistic and reliable answers on CC behaviour of the rubber are derived from the measurements.

The STS twin screw extruder from Coperion is celebrating its 15th birthday in 2019. Just in time for this anniversary, the company has expanded the series by one more size: the STS 25 Mc11 extruder with a 25 mm screw diameter is designed especially for research and development tasks as well as for production of small batch sizes of 2 kg and more, achieving throughputs of up to 90 kg/h. It will be shown for the first time at Chinaplas 2019.

The transition period for the Elastomer Guideline published by the Umweltbundesamt (UBA), Germany’s federal environmental agency, for assessment of elastomers in contact with drinking water, ends on 31 December 2021. Sulphur cross-linked compounds currently in use in drinking water applications can no longer be used after that time. The German rubber compounder Kraiburg based in Waldkraiburg in Bavaria has succeeded in developing compounds that can be used in elastomer solutions for drinking water applications after that date.

Rubber/metal composites tend to fail prematurely due to loss of adhesion of the rubber to the metal substrate, when they are exposed to aggressive conditions such as marine environments. The aim of this work is to elucidate the adhesion failure mechanism by cathodic disbonding and anodic undermining tests using a commercial bonding system for bonded rubber/metal.

With the help of a virtual DoE different injection points (red crosses) are compared regarding injection pressure and air entrapments for an LSR pot cloth. While Design 15 and 43 have a high risk of undesired air bubbles, Design 33 combines a good filling behaviour with a low pressure demand. (Source: Sigma)

The German company Sigma Engineering GmbH from Aachen is presenting its Sigmasoft Virtual Molding software and the enclosed Autonomous Optimization technology at various exhibitions in spring 2019. The software helps to find the ideal configuration of part, mould and process in one calculation. The Autonomous Optimization and the included possibility to conduct virtual Design of Experiments (DoE) help the users to improve existing injection moulding tools and processes as well as to virtually test different configurations and innovative approaches.
