Secondary Processes

	Butt Splice - Butt Splices are the most common method to finish an extrusion into a gasket or seal. Some materials can be heat welded while others need to be vulcanized. Extruding and butt splicing is usually more cost effective than fully molding a part.
	Mitre Splice - Applications requiring a picture frame configuration can be spliced using a 45 degree mitre to form the frame.
	Molded Corners - When function and reliability must be optimized, corners are molded separately then butt spliced into a frame. This process moves the vulcanized splice away from the corner, which makes it stronger. Molded corners can be designed for gentle radii up to a full square.
	Notched Corners - Notched corners employ aspects of the mitre splice, but accomplish it without having to fully cut the extrusion. This method works particularly well with P-strip or J-seal designs.
	Notching/Punching/PSA Application - Whether in-line or as a secondary operation, parts can be notched, punched, or PSA (pressure sensitive adhesive tape) can be applied to improve functionality.
