RAMPF – Material & Machine for Filter Production

Grafenberg, Germany, January 18, 2023 --(PR.com)-- The international RAMPF Group is presenting reactive polymers and automated dispensing solutions for filter production at Filtech 2023 from February 14 to 16 in Cologne, Germany – Hall 8 / Booth E29.

For filter manufacturers, RAMPF offers a comprehensive product and service portfolio for sealing, casting, and bonding:

Reactive resin systems based on polyurethane, epoxy, and silicone from RAMPF Polymer Solutions.

Automated dispensing systems for the processing of single-, dual-, and multi-component reactive resin systems from RAMPF Production Systems.

Air and HEPA filters as well as oil and hydraulic filters are manufactured in a wide variety of designs and must always perfectly fit the application. With materials and processing technology form a single source, RAMPF is maximizing both the quality of filters and the cost-effectiveness of their manufacturing process.

Reactive resin systems for air and HEPA filters

- Sealing foams: Before being installed in ventilation systems, air filter elements are sealed using RAMPF’s RAKU® PUR liquid and thixotropic FIPFG sealing foams. The polyurethane systems exhibit first-class physical properties as well as short processing times. Sealing foams for special requirements are also available, including systems with antibacterial properties according to DIN EN ISO 846 (11/2020).

- Conductive casting resins: For filter elements that are used in ATEX environments (explosion-proof environments), RAMPF offers soft (Shore A 85) and hard (Shore D 80) systems. These exhibit good flow characteristics, are machineable, have a conductivity of 0.03 MOhm/cm and good chemical resistance.

- Casting resins: Compact, two-component RAKU® PUR casting resins are used to fix the filter elements in the filter frame. The polyurethane systems exhibit good flowability, are silicone-free, and can be equipped with antibacterial characteristics. Due to the good adhesion to plastic, especially ABS and PS, the connecting bridges can be used as a supporting element, which increases the stability of the filter elements.

- Rigid foams: Filled RAKU® polyurethane rigid polyurethane foams are used to fix the filter medium in the frame. Here, high mechanical strength, a highly abrasion-resistant surface, and very good adhesion and chemical resistance are a must.

Reactive resin systems for oil and hydraulic filters

For the manufacture of oil and hydraulic filters, RAMPF has developed numerous adhesive systems and casting compounds based on polyurethane and epoxy. These exhibit good adhesion to plastic and metal as well as optimized hardening properties and fast process times, which increase the productivity and efficiency of production.

Automated production systems with integrated dispensing technology

Mixing and dispensing systems from RAMPF Production Systems guarantee the precise and fast processing of reactive plastic systems used for bonding and sealing in the filter industry. As filters are mainly manufactured in large quantities, highly automated and flexible manufacturing solutions are must. Here lies another core competence of the company based in Zimmern ob Rottweil, Germany – holistic automation solutions.

The design and construction of large, complex systems is an everyday task for the company, and it has already delivered several hundred highly automated systems – true to the motto “combining dispensing expertise with automation expertise maximizes customer benefit”. This includes the integration of processes such as parts transport, plasma pretreatment, image processing, and sensor technology. Robots from KUKA, ABB and FANUC are used that are programmed precisely to the needs of the customer.

The production systems can also be equipped with the intuitive user interface RAMPF-HMI (Human Machine Interface), which makes all process information available to higher-level systems. This intelligent interaction between man and machine is a key prerequisite for further digitization and thus automation of production.
