Process for encapsulating a bowling pin

Abstract

A process for encapsulating a bowling pin includes placing a pin in a mold; injecting a molten plastic material into the mold to encapsulate the pin; and cooling the mold to produce a finished bowling pin wherein. The plastic material includes 80% to 60% of nylon and 20% to 40% of ion resin. Preferably, the ion resin is zinc ion resin.

Claims

Description

DETAILED DESCRIPTION OF THE INVENTION

[0006] A process for encapsulating a bowling pin in accordance with the invention comprises the steps of placing a pin in a mold, injecting a molten plastic material into the mold to encapsulate the pin, and cooling the mold to produce a finished bowling pin in which the plastic material includes 80% to 60% of nylon and 20% to 40% of zinc ion resin and a shell of the bowling pin includes 80% to 60% of nylon and 20% to 40% of zinc ion resin.

[0007] It is envisaged by the invention that the shell of the bowling pin has the advantages of being resistant to breakage, being resistant to wear and capable of generating crisp sound when a bowling ball hits the bowling pin.

[0008] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
