The "Quick Changer HS Flow" is a device that allows for color changes without stopping the extruder by switching valves between two extruders that extrude resin. There are two methods of use: the "Y Flow Method," where one extruder feeds resin to the head and the other extruder's resin flows out as overflow, and the "X Flow Method," which reverses the inner and outer layers. This enables a significant reduction in setup time and a substantial decrease in waste. 【Features】 ■ Allows for color changes without stopping the extruder ■ Enables significant reduction in setup time and waste ■ The main methods of use for this device are the "X Flow Method" and the "Y Flow Method" *For more details, please refer to the PDF document or feel free to contact us.
