FERMAPOR K31 FAST-CURE - Polyurethane Foam Gaskets 

... for High-speed Production

As the process specialists for Formed-in-Place Foam Gasket sealing technology, we know which foam seals are needed in the automotive, switch cabinet and packaging industries – the rapidly reacting FERMAPOR K31 FAST-CURE polyurethane foam systems.

Where swift further processing and early build times are the order of the day, FERMAPOR K31 FAST-CURE foam gasket systems come into play. Especially when efficient volume production of large orders is needed, and that with a high variability in the components, the fast tack-free times of fast-cure foams are decisive.

The Advantages of Fast-reacting FERMAPOR K31 FAST-CURE Foam Gasket Systems are for you

The reaction of the fast-cure material components displays a gradual start time of up to 30 seconds, so that even the short waiting times imposed by the injection molding process can be accommodated.

Employment of the MOLD’N SEAL processing (inline production of injection molding and foam sealing) with mixing head wait times of up to 30 seconds for part handling. 

Very short tack-free time for the fast-cure foam of approx. 120 seconds at room temperature after the dispensing of the part. 

Low investment: 

  • Extremely fast curing only needs short curing lines
  • Fast reprocessing and early assembly of the parts
  • Money and time savings by eliminating the need for intermediate storage and the logistical effort of entering and extracting parts from storage for further processing.
  • Cost savings through elimination of investment and energy costs spent on tempering ovens for the curing of foam seals. 
  • Special fast-cure foam seals meet the technical requirements of manufacturers within the automotive industry.
  • Perfect part protection against damp, dust, and other environmental influences
  • Low water absorption: depending on the part and the fast-cure system chosen, the whole system can attain protection classes up to IP69K.
  • Good adhesion to different material surfaces, on certain substrates after previous treatment.
  • Adjustable viscosity from fluid to paste-like, flexible as regards part geometry
  • Low bracing forces through different Shore hardness’s
  • Good recovery capacity: under test conditions (80 °C, 50 % compression, 22 h) the fast cure foam systems rebound by 96-98 %, essential for retaining high impermeability.

FIPFG Sealing Technology for the Automated Application of FERMAPOR K31 FAST-CURE Foam Gaskets

The FIPFG (Formed-In-Place-Foam-Gasket) sealing technology for the automated application of FERMAPOR K31 FAST-CURE sealing foams directly onto the part is the industry standard for rapid-cycle process production in such sectors as the automobile, switch cabinet and packaging industries. 

Wherever fast reprocessing and early assembly of the components is the name of the game, FIPFG dispensing with fast-cure foam seals is essential for the efficient volume production of large consignments.

It is in such rapid production that care is taken to connect processes with one another, so that product cycles are not interrupted.

FERMAPOR K31 FAST-CURE Foam Gasket Systems SONDERHOFF MOLD’N SEAL-Inline Production Integrating Two Processes 
with Two Processes 

SONDERHOFF MOLD’N SEAL combines the processes of injection molding and seamless foam sealing of parts seamlessly in a single production cell. This saves investment, storage, and personnel costs. For example, part handling is handled by one robot, as opposed to two previously.

The employment of FERMAPOR K31 FAST-CURE systems specially designed for the SONDERHOFF MOLD’N SEAL process allows a gradual reaction time for the material components in the mixing chamber of up to 30 seconds. This waiting time is used for part handling between the part removal from the injection molding machine and the foaming of the part under the mixing head. FERMAPOR K31 FAST-CURE systems are customizable for many different injection molding cycles.

The Fast-Cure foam system is dispensed directly on the still-warm injection molding, foams up to form a seamless seal and, after a very short tack-free time of approx. 120 seconds, is ready for further processing.
