The influence of mould cavities' surface structure on their contamination when processing polymers

Abstract

The process of manufacturing polymeric material products includes the entire processing system; from their properties and the technical level of the manufacturing device, through its control and regulation system, and the manufacturing tools. This article deals with the study of aluminium alloy materials used in the manufacture of moulds-with different coatings, in order to reduce the surface contamination of the cavity moulds. The reason for choosing this topic is to discover a way as to how to understand the contamination process. The method chosen for eliminating such contamination is then, dependent on the degree of knowledge regarding the state and cause of the problem in the production process under investigation. © 2019 Trans Tech Publications Ltd, Switzerland.
