Benefits:
-
May reduce seal costs through automation
-
Specific products suitable for oil and coolant sealing
-
Allows flexibility in component design
-
Reject rates may be reduced by precise gasket positioning
-
Allows seal fabrication/placement to be integrated with part fabrication
-
Self-priming grades for stay-in-place adhesion
-
Outstanding resistance to environmental degradation
-
Easy-to-process two-part system: 1:1 mix ratio
-
Maintains elastomer properties from -40 to 150°C and above
-
Fast cure at high temperature (typically 30 to 90 seconds at 150 to 180°C, depending on substrate and bead cross-section)
-
No post cure typically required; seal ready for use after initial cure
Process:
In situ injection molding of compression seals uses specialty liquid silicone elastomers. Component to be sealed (plastic or metal) is placed in injection molding tool, which is then closed. Silicone elastomer is injected into seal cavity, then after short cure at high temperature, the mold is opened and the part with the integrated seal is removed.
