Wear protection on plastics processing machines: Symposium in Würzburg

21.02.2022 The renowned symposium “Wear and Wear Protection on Plastics Processing Machines” of the SKZ Plastics Centre on 5 and 6 May in Würzburg, Germany, will deal with the manufacturing processes of injection moulding, extrusion and compounding as well as the causes of wear attack on plasticising units, processing machines and tools. The conference will be chaired by Prof Dr Markus Lake from the Niederrhein University of Applied Sciences, Department of Mechanical and Process Engineering.

Innovative plastic products require optimised processing and manufacturing methods in order to survive in global competition. The continuous development of plastics, additive systems and processing techniques in conjunction with an increase in productivity place extremely high demands on the machine and tool technology used.

Effects on machines and tools

"Starting from a consideration of the polymer materials used, the additives, the fillers and reinforcing materials, we want to look at the effects in terms of wear and corrosion on the machine and tool components used," says Lake. "An entirely new aspect of this year's event is looking at strategies for early detection of wear and predictive maintenance using appropriate predictive models."

From the field of research, results on wear protection using lubricant-filled microcapsules in thermoplastic compounding and measurement and analysis techniques for non-destructive and non-contact wear measurement will be presented. "Our friction and wear tests showed a reduction in wear of up to 85 percent on plastic-steel pairings. Components thus last significantly longer and produce less microplastic," explains Moritz Grünewald, one of the presenting researchers from the Materials Development Group at SKZ.

Practical solutions

The symposium on wear and wear protection will shed light on possible causes of wear and corrosion attack on plasticising units, processing machines and tools and show the resulting problems for product quality. Based on these findings, practical solutions will be presented to protect components of plasticising units and processing machines as well as tools efficiently and effectively through a suitable choice of materials and innovative surface technology. In addition to the appropriate selection of materials and surface technologies, participants will receive information on the extent to which wear attack can be avoided by a suitable choice of parameters in the processing procedure.

The event will be held in compliance with the current corona rules.
