Expert Skill of Injection Molding - A New Composite Processing Based on DFFIM

Abstract

This paper describes expert skills and qualifications needed for a successful injection molding process. Injection molding is a technology for manufacturing plastic products, where the resin is melted at high temperatures and injected into the mold. The plastic material is then maintained into a certain shape by cooling it. Injection molding can produce many same shape moldings, however this is not an easy process. Experts have a short time between checking the molded item and changing its initial conditions. Therefore expert skills is very important aspect in the process besides measurements. Experts confirm the resin in solution repeatedly, and to obtain them, the subject use wearable camera attached to the head. The actual process of molding is recorded using wearable cameras to show the line of sight during the process. In this paper, the skills needed for molding were investigated.
