Vulcanized or transfer molded corners provide a superior solution to butt joints in critical sealing applications. 

The transfer molding process involves connecting two or more rubber extrusions using a moldable material from a like compound.

This ensures material compatibility and avoids concerns about the breakdown of a joint over time. That’s why in applications such as silicone curtain wall gaskets, frames with molded corners are used almost exclusively.

Compared to butt joints and adhesives, transfer molding produces a bond with greater integrity and better appearance. Cooper Standard ISG can use this technique to create simple corners or complex frames made up of multiple dissimilar profiles.  

As an added benefit, installing a gasket as a single component not only reduces the potential for leaks, it can improve the efficiency of the assembly process.
