Dynamic Melt Mixer Inc. of Manchester, Mass., claims its machine mixes resins and makes alloys on a single-screw extruder, a process that normally requires twin-screw extruders.
The company builds new machines and also supplies the Dynamic Melt Mixer as a retrofit onto existing single-screw or twin-screw extruders, according to President Desi Csongor.
The first part of the process uses a main single-screw extruder to feed the melt to a second section, which uses a series of rotors and stators. Satellite extruders feed materials to the melt. The rotors and stators achieve efficient, dynamic mixing, blending components under tightly controlled shear rates and temperatures, Csongor said.
Temperature and viscosity can be pre-set to make material suited for a specific end-product, he said.
“It's the simplest, most cost-effective method and it's retrofittable to any existing extruder,” Csongor said.
The machine has blended ABS and polycarbonate, among other materials.
