At our booth, we will propose products that enable "improved production efficiency" and "cost reduction" through the stabilization of plastic molding. In particular, for recycled plastics, which have been gaining importance recently, the representatives of each device will explain the test results verified with demo machines conducted in-house. We will have a demo unit of the polymer moisture meter "AquaTrack V," and customers who bring samples will be able to conduct actual measurements. Larger samples, such as preforms, can also be measured as they are. *Please inquire in advance about the types of samples. Additionally, we will present a booklet titled "Dr. Plastic Molding's Rheology Lecture Notes," summarizing the understanding of material properties and predictions of viscosity and flowability, to those we speak with at the booth. We sincerely look forward to your visit. ◎ Exhibition Contents - Polymer moisture meter "AquaTrack V" (actual machine on display; demo measurements available) - Ultra-compact polymer dehumidifying dryer "Card Series" (full-size mock-up on display) - Capillary rheometer "R6000" (panel on display)
