Research on Catalyst Penetration Process of Patternless Casting Manufacturing Technique

Abstract:

Pattenless Casting Manufacturing (PCM) technique is a kind of Rapid Prototyping based on droplet injection, using discrete nozzle to jet the catalyst. The quality of scanning lines has the most important effect on the sand strength, its surface quality and dimensional accuracy. The penetration and curing rules of the catalyst in the resined-sand particles are the main factors to determine the shape of the scanning lines. In order to study the penetration rules of the catalyst in the resined-sand, the penetration process of a single droplet and scanning lines are analyzed theoretically and verified by experiments. The important parameters of the forming process are determined based on the research and experimental results. It will provide the foundation to improve the forming quality of PCM technique.
