Development of a Friction Testing Apparatus for Demoulding Force Prediction

Research output: Contribution to conferencePaperpeer-review

Abstract

Friction between replication tools and replicated parts determines the force required to demould the part and also the stresses which develop in both the tool and the part during the demoulding process. Standardized equipment and procedures have been developed which strive to improve the repeatability and reproducibility of friction tests. Specific test standards, describing sled-type tests, include JIS K 7125, ISO 8295 and ASTM D1894. However these tests do not produce results which are representative of the conditions typically found within replication tools such as injection moulds or embossing tools. This paper reviews how this challenge has been addressed by other researchers and describes the development of an apparatus to measure friction under typical replication conditions. Experimental results for the thermal characterization of the device are reported.
