100L Sigma Kneader with Screw Discharge – Built for Silicone Rubber

Karvil Machinery supplied a 10L fully explosion-proof sigma mixer with screw extrusion discharge and cooling system to a UK customer processing organic siloxane copolymer modified acid resin. The customer shared excellent feedback and real operation video.

Modern industrial blenders comply with CE, ATEX, food-grade standards while boosting mixing efficiency & safety.

Optimized sigma blade design delivers maximum torque with minimal power for high-viscosity mixing efficiency.

Recently, we successfully manufactured and shipped a highly customized 50L Explosion-Proof Vacuum Planetary Mixer to one of our long-term overseas partners. This advanced equipment will be directly applied to a highly demanding and sensitive project: the research and manufacturing of engine propellants. Repeat Orders: The Ultimate Proof of Quality and Trust This successful delivery marks another milestone in our ongoing partnership with this valued VIP client. Over the years, they have continuously chosen our mixing solutions, having previously purchased our Kneader Machines and standard Planetary Mixers. Thanks to the exceptional stability, reliable long-term performance, and our prompt after-sales support, our machines have earned high praise from their engineering team. When their new engine propellant production line required a mixer with ultra-high safety and precision standards, they bypassed other suppliers and entrusted this critical project to us once again.

We are proud to announce the successful manufacturing and testing of our latest customized equipment: a 300L Explosion-Proof Vacuum Sigma Kneader. This high-performance Z-blade mixer is currently being packaged and will soon be shipped to our long-term strategic partner in Romania. Designed specifically for compounding Nitrile Butadiene Rubber (NBR) and adding high-density fillers, this machine represents our commitment to providing safe, efficient, and heavy-duty mixing solutions for the rubber and chemical industries.

Finding unmixed powder at the bottom of your mixer is a common manufacturing headache.
