Method for forming a recyclable seal on an automotive climate control system door

A recyclable seal is formed on the surface of a climate control system door by placing the door into a mold having channels for receiving a foammelt, forming the foammelt by melting a solid sealant material and mixing a foaming agent therewith, supplying the foammelt mixture under a predetermined pr...

Zusammenfassung:	A recyclable seal is formed on the surface of a climate control system door by placing the door into a mold having channels for receiving a foammelt, forming the foammelt by melting a solid sealant material and mixing a foaming agent therewith, supplying the foammelt mixture under a predetermined pressure to the mold so as to flow through the channels and through openings in the door to form an interconnected seal on opposite sides thereof, venting the channels along substantially the entire length thereof so as to maintain a relatively low differential pressure across the foammelt mixture to force the foaming agent to a center section of the seal so that a gas pocket is formed therein, and cooling the mold while supplying the foammelt mixture thereto.
