聚氨酯座椅一体成型工艺

An Integral Forming Process of Polyurethane Seats

阐述了聚氨酯座椅整体成型工艺的概念和发展惰况,并对其成型工艺、工艺特点和生产厂家进行了介绍。该种座椅是将座椅织物外套在发泡模腔内真空成型,然后在同一模腔内灌料发泡。在对座椅进行改型时,只须将装在展延器上的、由计算机控制的20多个推进器的技术参数作适当的修改即可完成。

The conception and development of an integral forming process for making polyurethane seats are described in this paper. Its forming process, technical features and its manufacturing are presented. In order to make this integrally formed seats, first the fabric covers of seats are vacuum formed in the foam mould chamber, then filling and foaming in the same chamber. In case the seat is modified, only change the appropriate teohnical parameters of more than 20 propelling arms, controlled by a computer, and installed on an extension device is needed.
