- Drying and post-processing equipment, including dryers and related material-handling units.
- Special process lines for CMC cellulose, alcohol recovery, condensers, and related chemical-process systems.
The company’s public product structure indicates a significant overlap between plastics processing and adjacent industries such as coatings, adhesives, pigments, modified starches, silicone materials, and chemical intermediates.
Products and Technologies
The company’s product portfolio centers on equipment used to process viscous, cohesive, and difficult-to-disperse materials. Public listings identify several equipment classes and configurations.
Core equipment categories
- Sigma kneaders and dispersion kneaders for high-viscosity formulations.
- Internal mixers and Banbury-type mixers for intensive rubber and compound mixing.
- Twin-screw extruders and pelletizing systems for compounding and downstream forming.
- Vertical and hydraulic tilting kneaders for batch processing and discharge control.
- Ribbon mixers, V-mixers, and double-cone mixers for powder and granule blending.
Technical characteristics
Public product descriptions indicate that the company’s equipment is configured for temperature control, viscosity-sensitive mixing, and flexible discharge methods such as hydraulic tilting or screw discharge. Materials of construction cited in third-party descriptions include carbon steel, stainless steel, and glass-lined vessels, with surface treatment options such as mirror polishing or fluoropolymer coatings for corrosion resistance and reduced contamination risk.
For plastics and rubber applications, these design features are important because compounding performance depends on shear intensity, residence time, heat transfer, and batch uniformity. In practice, that makes such equipment suitable for formulations involving color masterbatch, fillers, elastomers, silica gel, silicone rubber, adhesives, modified plastics, and carbon-based materials.
Special-purpose systems
The company also publicizes CMC cellulose complete sets, including auxiliary units such as alcohol recovery towers and condensers. This indicates capability beyond standalone mixers and into integrated process systems for specialty chemical and polymer-adjacent production.
