Choose the right kneading solution for your material, production capacity, and discharge requirements.
01. Material Loading
Load raw materials into the mixing chamber.
⬇️
02. Intensive Kneading
Dual sigma blades fold, shear, and knead the material for uniform mixing.
⬇️
03. Process Control
Adjust blade speed and use optional heating or cooling to meet process requirements.
⬇️
04. Material Discharge
Discharge the finished batch by hydraulic tilting or screw discharge, depending on the configuration.
Every application is different. We configure the sigma mixer around your material, process and production requirements.
01 — Material & Process
We evaluate material properties, viscosity, batch size and processing conditions.
02 — Capacity
Lab, pilot or production scale, from 2L-over 6000L.
03 — Heating, Cooling & Vacuum
Configure jackets, heating or cooling systems and vacuum processing to match your process.
04 — Discharge Solution
Choose tilting discharge, screw discharge or a customized discharge system for your production needs.
