Abstract
A method for molding amorphous polyether ether ketone including steps of preparing a molten mass including polyether ether ketone, cooling a mold assembly to a temperature of at most about 200° F., and injecting the molten mass into the cooled mold assembly.
Claims20
A system for molding comprising:
- a mold assembly defining a cavity and a fluid channel;
- a cooling system in fluid communication with said fluid channel, said cooling system supplying a cooling fluid to said fluid channel, wherein said cooling fluid cools said mold assembly to a temperature of at most about 200° F.;
- and
- a polymer injection subsystem in fluid communication with said cavity, said polymer injection subsystem supplying a molten mass to said cavity, said molten mass comprising polyether ether ketone.

A system for molding a dielectric layer onto a head of a fastener body, said fastener body comprising said head and a shaft, said system comprising:
- a mold assembly defining a cavity and a fluid channel, wherein said head of said fastener body is at least partially received in said cavity;
- a cooling system in fluid communication with said fluid channel, said cooling system supplying a cooling fluid to said fluid channel, wherein said cooling fluid cools said mold assembly to a temperature of at most about 200° F.;
- and
- a polymer injection subsystem in fluid communication with said cavity, said polymer injection subsystem supplying to said cavity a molten mass comprising polyether ether ketone, wherein said molten mass contacts said head of said fastener body and forms said dielectric layer, wherein said dielectric layer has a crystallinity of at most about 15 percent.
