Abstract
A two-part resilient bumper formed by depositing a first liquified resilient material into a bumper cavity of a mold plate, distributing the first liquified resilient material over a bottom portion of the bumper cavity before depositing a second liquified resilient material into the bumper cavity on top of the first liquified resilient material, and curing the first and second liquified resilient materials to form a first resilient material bonded to a second resilient material, wherein the first and second resilient materials have different performance characteristics when cured.
Claims20
A method for making resilient bumpers comprising:
- depositing a first liquified resilient material into a bumper cavity of a mold plate;
- depositing a second liquified resilient material into the bumper cavity of the mold plate on top of the first liquified resilient material before curing the first resilient material;
- and
- forming a first resilient material bonded to a second resilient material by curing the first and second liquified resilient materials deposited into the bumper cavity,
- the first and second resilient materials having different performance characteristics.
A method for making resilient bumpers comprising:
- depositing a first liquified resilient material into a bumper cavity of a mold plate;
- depositing a second liquified resilient material into the bumper cavity of the mold plate on top of the first liquified resilient material before solidifying the first resilient material;
- and
- forming a first resilient material bonded to a second resilient material by solidifying the first and second liquified resilient materials deposited into the bumper cavity,
- the first and second resilient materials having different performance characteristics.
A method for making resilient bumpers comprising:
- depositing a first liquified resilent material into a bumper cavity of a mold plate by dispensing the first liquified resilient material from a first supply line disposed above the bumper cavity;
- depositing a second liquified resilient material into the bumper cavity of the mold plate on top of the first liquefied resilient by dispensing the second liquified resilient material from a second supply line disposed above the bumper cavity material before solidifying the first resilient material;
- and
- forming a first resilient material bonded to a second resilient material by solidifying the first and second liquified resilient materials deposited into the bumper cavity,
- the first and second resilient materials having different performance characteristics.
