Specify a sigma mixer for high-viscosity thermoplastics using batch mass, working volume, torque, temperature, vacuum, material trials, and discharge needs.
Prevent filler lumps, batch variation, and rework in waterproof compounds by controlling materials, charging, mixing milestones, sampling, and cleaning.
Use this sigma mixer factory acceptance test checklist to verify specifications, materials, controls, safety, vacuum, thermal functions, discharge, and records.
Test a vacuum sigma kneader for silicone with representative material, vacuum stability, blade action, heating, density, discharge, residue, and repeatability.
