The Lab Stainless Steel Vacuum Sigma Kneader is a precision-engineered mixing solution specially designed for laboratory research, product development, and small-batch production. It is mainly used to handle high-viscosity materials such as silicone sealants, adhesives, hot melt, rubber compounds, polymers, inks, and chewing gum etc
Built from high-grade stainless steel, this small-scale sigma kneader machine ensures durability, corrosion resistance, and easy cleaning, thus the precision lab kneader is ideal for handling high-viscosity materials such as polymers, silicone, adhesives, pigments, ceremic , chemical compound and pharmaceutical & food etc.

When this sigma kneader mixer working ,its two counter-rotating sigma blades rotating in different speed in opposite direction , generating intensive shear forces to mix high-viscosity and sticky materials with precision and consistency. This rotating action ensures uniform dispersion of fillers, pigments, plasticizers, or additives.

If equipped with a vacuum system, the vacuum sigma kneader machine machine can effectively remove trapped air and gases during processing, improving product quality and stability.
For these materials required bubble-free compounds, like adhesives, medical-grade silicone, or epoxy paste, the a vacuum system removes trapped air and gases, thus ensuring homogeneous mixing, bubble-free products, and perfect performance of final products.
With PLC control options, with its intelligent automation, and precise control , the small-scale sigma kneader machine can monitor and manager automatically ,including mixing speed, temperature, and timing etc.

This Laboratory kneader mixer offer higher productivity, better quality, and lower operational cost ,it is perfect for R&D labs, universities, material testing centers, and pilot production lines etc.
