Heating of golf balls prior to painting
View Patent ↗A method for preheating golf ball covers prior to painting. The process comprises forming a golf ball with a cover, then heating the cover from about 90° F. to about 150° F. for 1 to 3 hours in a heated enclosure prior to applying a coat of primer or paint to the ball. This is done to accelerate the evaporation of paint solvents, immediately after the paint is applied. The painted balls are subsequently dried in a heated enclosure at about 105° F. to 108° F. All additional coats of primer or paint are applied in a similar fashion, wherein the balls are painted while still in the heated state and not cooled down.
1. A method of manufacturing a golf ball comprising:
forming a plurality of golf balls, each having a cover;
placing the golf balls in a ventilated tray having a plurality of ball station positions, each station having a replaceable ball support insert friction-fitted therein with a plurality of recessed conical pins mounted on the inner perimeter for suspending the golf ball;
heating the golf ball covers to a temperature greater than about 100° F.; and
applying at least one coat of paint to the heated covers.
2. The method according to claim 1 , wherein the heating of the golf ball covers is to a temperature within the range of about 100° F. to about 150° F.
3. The method according to claim 1 , wherein the cover is select from the group consisting of a thermoset polyurethane, a thermoplastic polyurethane, an ionomer thermoplastic elastomer, and an ionomeric thermoplastic elastomer.
4. The method according to claim 1 , wherein heating of the golf ball cover is for about one hour to about three hours in a controlled heating enclosure.
5. The method according to claim 1 , wherein after applying the coat of paint to the golf ball cover, it is then dried in a heated drying room at about 105° F. to about 108° F.
