塑料异型材的挤出是一种既有理论根据又有实践经验的高度熟练的综合技术及技能(包括配方、工艺、设备、模具和质量等),国内目前这方面的综合技术及技能比较落后。为了促进塑料异型材加工,充分吸收消化国外先进技术,为四化服务,笔者拟以下几点与同行们共同进行坦率、深入的探讨。 Extrusion of plastic profiles is a highly skilled comprehensive technology and skills (including formulas, processes, equipment, molds, and quality, etc.) that have both theoretical and practical experience. The current domestic integrated technologies and skills are lagging behind. . In order to promote the processing of plastic profiles, fully absorb and digest foreign advanced technology, and serve for the four modernizations, the author intends to conduct frank and in-depth discussions with colleagues in the following points.
