Thermador Increases Cooktop Reliability, Reduces Cost
With Loctite 5920 Formed-In-Place Gasket
Realizes equipment investment in less than one year
Problem:
Thermador, a major manufacturer of high end gas ranges and cooktops, was looking to replace its current pre-cut gasketing system. Pre-cut, extruded foam gaskets were being used to create a seal between porcelain-coated burner plates and the glass or stainless steel cooktops. These gaskets were designed to enhance cleanability by preventing food or liquids spilled while cooking from seeping under the burner, with cooking temperatures to 650°F. Proper assembly was required.
In addition, the method of assembly was costly and time- consuming. Assembly technicians applied rubber cement to the pre-cut gaskets and manually put them in place on the burner plates.
Solution:
Loctite 5920 Formed-In-Place Gasket.
Loctite 5920 is dispensed by an Asymtek high-pressure spool valve onto a porcelain-coated burner plate.
Using an Asymtek automated dispenser equipped with a high-pressure spool valve fed by a five-gallon pail pump, Loctite 5920 is now dispensed in two continuous beads, one on top of the other, to obtain the required bead height of 0.025 inches above the rim of the part.
Loctite 5920 is a room temperature-curing, formed-in-place gasketing compound. Its non-sag copper paste adheres easily to metal, glass, natural and synthetic fibers, wood, ceramics, other silicone rubbers, and many plastic substrates. Loctite 5920 is used to fill voids and irregularities in surfaces maintaining a positive seal in applications up to 662°F (350°C).
Results:
Thermador has realized a total annual savings in excess of $20,000. In fact, with the material savings that resulted from replacing the pre-cut gasket with Loctite 5920, Thermador was able to pay back its equipment investment in less than one year.
