JSAE 2019 in Yokohama: Exhibitions of Plastic Processing Technologies

The application of engineering plastics for interior and exterior parts, valves, and sensors



  The Automotive Engineering Exposition 2019 Yokohama event was held from May 22 to 24 2019 at the Pacifico Yokohama convention center. Numerous exhibitions of plastic products in support of automotive electrification and weight reduction were on display at the event.

  This article reports on the exhibitions related to plastic molding processing and secondary processing, as well as products that serve as reference for manufacturing. Particularly notable were exhibitions of cooling-related piping components such as pumps and valves, perhaps due to the fact that both internal combustion engine vehicles and electric vehicles have seen an increase in the number of components that can reach high temperatures. In addition, this report introduces a number of unique exhibitions from some of the more notable plastics processing manufacturers.
