High-quality plastic parts for the paper industry

At Wefapress, we are proud to have worked within the paper industry for many decades. Our years of experience and implementation of practical applications have enables us to develop high quality products that are bespoke to the paper industry. We create everything, from the highly resistant sheets, milled covers (that can have drilled or slotted perforation patterns) as well as fully finished parts. We guarantee first class quality at every juncture.

Our products are manufactured homogeneously from premium, ultra-high-molecular-weight polyethylene (PE-UHMW), for this application, we only use our virgin material. By using lubricants and specialist additives we have achieved the optimal qualities specifically for this material application, specifically extreme wear-resistance. Thanks to the press-sintering process that we use, we can ensure a stress-free internal structure which eliminates bowing. We can also produce semi-finished parts that can be further worked with a length of up to 10 meters without any weld seams.

Diffuser block

Our diffuser blocks are specially designed for your production process and offer an efficient and reliable solution for even fibre distribution. They are made of high-quality plastics and offer excellent resistance to wear and chemicals.

Drainage elements

Our drainage elements are an essential part of the papermaking process. They create micro-turbulence, equalise and drain the paper fiber slurry evenly, helping to improve paper machine efficiency and the quality of the end product.

Doctor blades and water scraper blades

Our doctor blades for the paper industry offer an efficient and reliable solution for the roll cleaning process. They are made of high-quality plastics and offer uniform contact pressure and excellent resistance to wear.

Sealing strips for suction rolls

Our suction roll sealing strips are essential for a smooth paper manufacturing process. They provide an efficient and reliable seal between the suction box and the rotating roll shell to ensure even dewatering and stable machine operation. A high graphite content guarantees minimum friction and excellent emergency running properties.

Radial header

At Wefapress, the focus in the manufacture of perforated plates for radial headers, rotary distributors and pulsation elimination tanks is on extremely smooth surfaces. this avoids unwanted deposits in the headbox. With the ability to manufacture perforated plates as monoblocks up to a diameter of 2,500 mm and a thickness of 200 mm, we set the required tone and standards within the industry. Our precise surfaces of the stepped drill holes provide optimum conditions for paper production without disruptive deposits.

Gear wheels for drying cylinder drives

Our gears for drying cylinder drives are specially designed for the highly demanding application in drying hoods of the paper machines. They offer a durable and reliable solution for optimising the drive process and helps to reduce maintenance costs. The gears are made of high-strength plastic and ensure precise power transmission with minimum wear.

Format limiters and forming fabric edge lifters

Our format limiters and edge lifters help to prevent the stock suspension from running apart and ensure even basis weights across the entire width of the paper sheet. This results in a clean forming section and fewer edge tears, which contributes to smooth operation of the paper machine.

Rod beds for coating units

Our rod beds for coating units are designed for maximum efficiency and durability. They enable an even coating and improve the surface quality of the paper. Thanks to the use of premium material, our rod beds are particularly resistant to abrasion and chemicals, resulting in a longer service life and lower operating costs.

Jaw coupling spiders for tambour drives

Our coupling stars for tambour drives offer a robust and reliable connection solution that is designed for the high loads in the paper industry. They enable even power transmission and minimise vibrations and noise during operation. Manufactured from wear-resistant plastic, they ensure a long service life and reduced maintenance costs.

Tambour storage lining

Our tambour storage lining is designed to extend the service life of the bearings and minimise maintenance costs. They offer excellent damping properties that result in reduced impact force on the bearings as well as reduced noise.

Screw hutch linings for screw conveyors

Our conveyor screw trough linings are specially developed to reduce friction and increase screw life time. They ensure even and uninterrupted transport of the fibers, rejects or other transported materials. Thanks to the use of high-quality plastic, they are particularly durable and resistant to abrasion and corrosion. This contributes to consistent production and reduced maintenance costs.

Overview:
Why is plastic an advantage in the paper industry?

Plastic parts offer numerous advantages in the paper industry compared to traditional materials such as metal or wood. Their superior corrosion resistance guarantees a longer service life, even in humid or chemically aggressive environments, which are commonplace in the paper industry. In addition, the lower density of plastic ensures lighter components, resulting in reduced energy costs during machine operation.

The easy shaping properties of plastic enables the production of complex shapes and profiles that are tailor-made for specific applications in paper production. This means that plastic parts for the paper industry are often more precise and efficient than their counterparts made from other materials. In addition, the flexibility in the production of plastic parts allows them to be quickly adapted to new or changing production requirements without costly and time-consuming modification measures.

Because many plastics are inherently low-friction, both the plastic parts themselves and the machine elements that come into contact with them are subject to less wear and tear. This results in lower maintenance costs and smoother operation. With their ability to dampen vibrations and noise, plastic components contribute to a more pleasant working environment and more stable machine operation, which in turn increases product quality.

The adaptability of plastic parts to the demanding conditions of the paper industry makes them an optimal choice for manufacturers looking for sustainable, cost-effective and high-performance solutions. With the added benefit that plastics are easy to clean and maintain, operational hygiene is improved, which is particularly crucial in the production of food packaging or medical packaging materials.

Sustainability and efficiency through innovative plastic solutions

The use of plastic parts in the paper industry brings considerable ecological and economic benefits.
Due to their durability and recyclability, plastic components are a sustainable choice for the paper industry, helping to reduce operational costs and enhance production efficiency.

Plastic materials for the paper industry

Choosing the right material is crucial for the performance of plastic parts in the paper industry. Wefapress offers a wide range of materials such as St 1000, CeramX, St 9000 MOS2, Ceradur, PS 1000, PS 4190, FlexGuard, St 7000 EHT and Nylatec 360, which have been specially developed for their applications in the paper industry.
