Learn safety features of sigma kneaders for high viscosity adhesives & sealants, emergency stop, covered drive, screw extrusion and ATEX CE certifications.

Compare tilting discharge and screw discharging for sigma mixers to understand which method improves unloading efficiency for high-viscosity materials.

Discover why vacuum sigma kneaders are essential for NBR rubber compounding with better degassing, temperature control, mixing quality, and safety.

Silicone rubber is one of the most demanding materials in industrial mixing. Its high viscosity, strong elasticity, and sensitivity to temperature make it difficult to process with conventional mixers. Choosing the right Sigma Mixer for silicone rubber is essential for achieving consistent product q
