Press-in-place gasket fabrication using extruded rubberized core

The patent uses a malleable core as a physical template or copy of the desired gasket shape. This core is inserted into a flexible die, and rubberized material is molded around it. The core itself becomes the pattern, eliminating the need for expensive custom injection molds while ensuring accurate reproduction of the gasket geometry. This copying approach allows rapid prototyping and design changes by simply replacing the core rather than remaking the entire mold.

The malleable core is prepared in advance as a pre-formed template that defines the gasket geometry. By having the core ready before the molding process, the actual production only requires inserting the core into the die and molding the rubberized material around it. This preliminary preparation of the core enables rapid production cycles and quick design iterations without the lengthy mold-making process required by traditional injection molding.

The system transitions from static, fixed injection molds to a dynamic setup where the malleable core can be easily replaced and reconfigured. The flexible die accommodates different core shapes, allowing the same molding apparatus to produce various gasket designs. This dynamic adaptability enables rapid design changes and prototyping while maintaining consistent molding pressure and material flow for reliable sealing quality.
