We are thrilled to announce the successful manufacturing and factory testing of two highly customized sigma kneader machines. Built specifically for a valued client in Saudi Arabia, these machines—a heavy-duty 850L Screw Extrusion Kneader and a 5L Lab-Scale Kneader—are engineered to process butyl rubber and high-performance adhesives.
This delivery highlights our capability to provide an end-to-end mixing solution, enabling our clients to seamlessly transition from laboratory formulation to large-scale industrial production.
Butyl rubber and industrial adhesives are notoriously difficult to process. They possess extreme viscosity, require immense shearing force to mix evenly, and are highly sensitive to temperature fluctuations during the mixing process. Standard mixers often fail, leading to uneven blending, motor overloads, or material degradation due to excessive friction heat.
To solve these industry pain points, we configured a robust, premium-grade mixing system for our Saudi client.
The centerpiece of this order is the 850L Sigma Kneader, specifically configured for heavy-duty, high-efficiency production without compromising material purity. Its core features include:
All-Stainless Steel Construction: Both the mixing chamber and the exterior are manufactured from premium stainless steel. This ensures zero rust contamination for sensitive adhesive formulations and makes cleaning and maintenance significantly easier.
Dual-Motor Drive System: To conquer the immense resistance of butyl rubber, a single motor isn't enough. We equipped this machine with a dual-motor drive, delivering maximum torque to the Z-blades for intense tearing, kneading, and folding of high-viscosity materials.
German SEW Gear Reducer: The transmission system is the heart of any kneader. By integrating an industry-leading SEW reducer, we guarantee smooth operation, high transmission efficiency, low noise, and exceptional durability even under peak loads.
Siemens Inverter (VFD) Control: For precise operational control, the system is powered by a Siemens inverter. This allows the operator to adjust the mixing speed smoothly according to different stages of the formulation process, while also protecting the motors from overcurrent and saving energy.
Screw Extrusion Discharge: Discharging sticky adhesives is always a headache. Our integrated screw extruder solves this. Once mixing is complete, the screw reverses direction to extrude the dense material seamlessly, readying it for the next packaging or molding step.
Dedicated Industrial Chiller & Cooling Jacket: Intense kneading generates massive friction heat. This 850L unit is paired with an external industrial chiller that circulates cold water through the mixing tank's jacket, maintaining strict temperature control to prevent the rubber and adhesives from curing or degrading.
Innovation requires testing. Alongside the 850L production unit, the client purchased a 5L Manual Tilting Kneader for their R&D laboratory.
This compact unit mimics the exact mechanical action of the larger machine and is also equipped with a cooling jacket for temperature control. It allows the client's engineers to test new adhesive recipes, adjust formulas, and verify material properties at a low cost before scaling up to the 850L machine. The manual tilting discharge makes it incredibly user-friendly for small batch handling.
The Middle Eastern market is seeing rapid growth in the demand for construction sealants, butyl tapes, and specialty adhesives. Our Saudi client chose us because of our uncompromising approach to quality—from using authentic SEW and Siemens components to executing precise engineering for dual-motor systems.
Whether you need a 5L mixer for laboratory research or a 1000L+ heavy-duty screw extrusion kneader for mass production, we provide tailored solutions for butyl rubber, silicone, hot melt adhesives, BMC/DMC, and more.
