Need Reliable Mixing for Rubber And Solvent Compounds? Discover The 400L Vacuum Sigma Mixer From Karvil Machinery

When working with high-viscosity materials like rubber, sealants, or solvent-based compounds, the biggest challenges are clear:

• Uneven mixing that compromises product quality

• Sticky residues that make cleaning a nightmare

• Heat sensitivity that risks material degradation

• Inefficient discharge, leading to waste and downtime

At Karvil Machinery, we understand these pain points because our customers face them every day. That’s why we engineered a solution: the 400L Vacuum Sigma Mixer with Screw Discharge and Steam Jacket — a machine designed from the ground up for the real-world demands of high-viscosity mixing.

✅ Designed for Complex Formulations

Whether you're blending rubber with organic solvents or manufacturing customized chemical pastes, this machine gives you precise control over vacuum, temperature, and discharge — all in one compact system.

• Dual Z-blade mixing system: Handles dense and sticky materials with ease

• Vacuum processing: Reduces trapped air and improves product integrity

• Steam jacket heating: Maintains stable temperatures (up to 70°C) for solvent-sensitive materials

• Screw extrusion discharge: Drastically reduces product loss and cleaning time

What Sets It Apart

• Built for reliability – All contact parts are made from mirror-polished SS304 stainless steel, ensuring hygiene and durability.

• Operator-friendly – Features like a hydraulic lifting lid, DN250 manhole, and viewing ports (with built-in light) make monitoring and cleaning easy.

• Safe for solvents – Equipped with fluororubber vacuum seals, resistant to aggressive chemical exposure.

• Customizable – Every unit can be tailored to fit your specific formulation and workflow.

Real Results for Real Manufacturers

One of our recent projects involved a Spanish customer needing to mix organic solvents with rubber. The challenge? Standard mixers couldn’t achieve homogeneity without overheating or leaving residue. With our sigma kneader, the customer saw:

• 30% reduction in mixing time

• Improved batch consistency across multiple runs

• Significant savings in cleaning and raw material recovery

Who This Mixer is For

• Manufacturers of rubber compounds, adhesives, and sealants

• Producers handling solvent-based or reactive materials

• Plants needing vacuum mixing with precise discharge

• Teams looking to scale up from laboratory to industrial production

Take the Next Step

If your current mixing solution is slowing you down or costing you product, it’s time to rethink your approach. The 400L Vacuum Sigma Mixer by Karvil isn’t just another machine—it’s an upgrade in your process capability.
