Research on the Dimpling in Multi-Point Thermoforming of Polycarbonate Sheet

Article Preview

Abstract:

Growing requirements of small-batch, high-quality and customized products are motivating the development of innovative flexible polymer processing techniques. The paper demonstrates the possibility of employing the multi-point forming (MPF) technology to produce low-cost, small-batch and customized polycarbonate (PC sheet components. Experiments have been performed by means of an experimental setup designed for processing polymer sheet and the overall investigation is focused on the characterization and evaluation of the effects of processing parameters on forming quality. The results show that the forming defects can be eliminated under appropriate processing parameters and that the shape of formed part is in good accordance with the desired shape.
