Japan’s IPF show is held every three years near Tokyo. In the latest iteration that convened in October this year, the focus was on application development; in other words, what one could achieve with Japanese injection machines already on the market. Of the many highlights, PlasticsToday’s pick is carbon-fiber composite processing technology from JSW (Hiroshima, Japan).
The technique uses multiple sheets of a polyamide powder-impregnated “semi-prepreg” that are press-formed into a rigid part, which is then transferred to an injection tool for selective back-molding. In other back-molding processes on show at IPF, the prepregs employed lacked structural integrity and had to be completely back-molded.
