Drainage elements from Wefapress® – a key to efficiency in paper manufacturing. Plastic drainage elements optimize the paper production process providing higher efficiency, longer service life, more precise quality, and reduced operating costs.
In modern paper production, drainage elements play a central role: they ensure that the pulp is drained evenly, moisture is reduced, and ultimately, the final product achieves high quality and dimensional stability. Plastic dewatering elements from specialized manufacturers like Wefapress offer significant advantages over traditional materials.
Materials and Manufacturing
Wefapress uses ultra-high-molecular-weight low-pressure polyethylene (PE-UHMW), manufactured homogeneously without recycled material. Additives such as lubricants or specific wear-resistant components significantly increase resistance to mechanical and chemical stress. The press-sintering process also allows the production of stress-free components – up to ten meters in length without welding seams.
Function and Application
Drainage elements deliberately create micro-turbulences in the pulp, compensate for thickness variations, and ensure uniform drainage across the paper web. They thus contribute significantly to more stable machine performance, reduced waste, and higher product quality.
Performance Features and Advantages
- Wear Resistance: The materials and additives make these elements highly resistant to abrasion and chemical attack.
- Durability & Low Maintenance: Homogeneous structure and material choice prevent weak points such as cracks or corrosion.
- Flexibility, Weight and Energy Savings: Lower mass compared to ceramic components and the flexible material makes handling much easier and very smooth surface reduces energy consumption during startup and continuous operation.
- Form Flexibility & Dimensional Accuracy: Plastic can be molded into complex profiles, slots, or holes precisely tailored to requirements, e.g., slotted or perforated dewatering elements.
Outlook and Sustainability Aspects
In addition to functional performance, ecological and economic factors are becoming increasingly important. Depending on application and composition, plastics like PE-UHMW can be recycled or regeneratively refined, reducing life cycle costs and environmental impact. Manufacturers like Wefapress offer a range of plastic grades such as “St 1000,” “CeramX,” “St9000MOS2,” and others, optimized for specific operating conditions. Visit: Wefapress.com
