3340 Dynamic Seal Channel Profile is 100% silicone and provides a rapid forming of the seal groove during your mold making process. Designed to create a precise seal channel for the Dynamic seal, the Dynamic Seal Channel Profile saves on labor costs by eliminating the need to manually create a channel via wax or other material.
Installation of the Dynamic Seal Channel Profile is by placing the seal profile around the molds perimeter flange, on top of 1mm (0.040") thick sheetwax, using a super glue #7697 adhesive to bond the seal profile to the sheetwax. The 1mm of sheetwax ensures the ideal depth for the Dynamic Seal to properly compress and seal when the mold is fully closed. With the sheetwax and 3340 profile in place, coated with PVA, the application of tooling gel coat and then the fiber-reinforced mold laminate can be hand-laid or vacuum infused over the profile leaving the precise groove needed in the final mold.
