AT394Lab Single Screw Extruder is used for mixing and processing of high molecular polymers such as engineering plastics, modified plastics and color master batches. It is suitable for lab test and quality control, teaching research and small scale production. Matched with different auxiliaries can extrude pellets, sheet, pipe, etc. (optional configuration). PID/LED/RKC intelligent digital temperature controller, high precision digital instrument display all the parameters of the extrusion. Material for Screw and Barrel: 38CrMoAl chromium molybdenum alloy, surface quenched, nitride, chromium plating, polishing and ultra-precision honing process, hardness HRC55~60, roughness Ra is less than or equal to 0.4 μm, depth of reach more than 0.6mm.
