Xtrutech offers a flexible approach, enabling us to work closely with our customers to make important custom modifications or upgrades that improve performance, productivity, and profitability. As a global manufacturer of adhesive extruders, the XTS twin screw extruder can be configured for the continuous production of hot melt adhesives and reactive sealants, with barrel lengths from 24 to 60 L/D. Pressure-sensitive adhesives can also be accommodated for specific applications. Choose from a wide range of ancillary equipment, including side-feeding options for solid ingredients, multiple liquid feed systems, and high-accuracy gravimetric feed systems for precise material dosing. Vacuum and venting solutions are also available to suit specific process requirements.
Adhesive Extrusion Process
The XTS twin screw extruder is suitable for producing a wide range of adhesive and sealant formulations, including:
- Hot-melt adhesives (e.g., glue sticks)
- Silicone sealants
- Two pack adhesives and sealants
- Medical adhesives
- Security tapes
- Die-cut labels
- Polypropylene foam
- Pressure-sensitive adhesives (e.g., packaging)
The XTS hot melt extruder offers short residence times and high throughput rates, helping manufacturers produce higher-quality products at lower unit costs. The flexibility of the process section, combined with a segmented, interchangeable screw configuration, enables the XTS twin screw extruder to effectively manufacture a broad range of adhesive and sealant formulations.
Compared to traditional batch mixing systems, continuous twin screw extrusion offers improved process consistency, faster production, shorter changeovers, and reduced material waste. Manufacturers can achieve tighter control of temperature, shear, and residence time, helping minimize batch-to-batch variation while improving overall production efficiency.
The XTS twin screw extruder offers significant improvements in product quality and consistency. In addition, savings in manpower and power requirements can be significant when compared to batch systems. Recipe management also helps ensure consistently high product quality without batch-to-batch variations.
Benefits and Applications
Manufacturers worldwide are increasingly replacing traditional Ross mixers, kettle mixers, and other batch processing equipment with continuous adhesive extruders to improve production efficiency and product quality. Continuous extrusion eliminates repeated heat-up and cool-down cycles while providing greater control over temperature, residence time, and mixing conditions throughout production. These advantages help reduce waste, increase throughput, and deliver more consistent adhesive performance. Whether you're producing specialty formulations in a laboratory twin screw extruder or scaling up to high-volume commercial production, the XTS platform is engineered to match your formulation and throughput requirements.

Quality Assurance from Feed to Finished Product
Consistent adhesive quality begins with precise process control. Xtrutech integrates gravimetric top feeders, twin screw side feeders, and precision liquid injection systems to accurately deliver polymers, fillers, tackifiers, plasticisers, oils, and reactive components throughout the extrusion process. Vacuum degassing and Xtrutech’s vent port stuffer technology remove moisture, trapped air, and residual volatiles while preventing product loss, helping improve product consistency and process stability.
Xtrutech has helped manufacturers around the world achieve better extrusion performance through engineered processing solutions. Every laboratory twin screw extruder and production system is configured to meet specific formulation requirements, while the Xtrutech Innovation Centre allows customers to validate formulations, optimize screw profiles, and refine processing conditions before scaling to full production. Combined with ISO-certified quality management, EcoVadis Bronze recognition, and global engineering support, Xtrutech helps manufacturers produce consistent, repeatable results with confidence.
