Construction of Bowling Pins
The raw material used to construct bowling pins is unused, hard maple wood. The block of maple wood joined together with the help of glue and turning on a lathe to form a specific shape. After getting a perfect shape of the pins to require beautification through the coating.
After forming a proper shape these pins are coated with a glossy plastic material, painted, and finally covered with a clear glossy finish. The Ethylcellulose coating is also done to enhance the durability of the coating. It is a seven-layer process. In the first step, the pins are dipped into a coat to seal the pores of the maple wood blocks and then apply the second layer to provide a solid bond for the following layers. Finally, 5 more layers of Ethylcellulose are applied.
Just after the first layer of Ethylcellulose, a nylon mesh sock is used to cover the pin, which acts as a solid iron reinforcing bar or the same as a straw in bricks that provide a stable structure for all the layers.
DuPont’s Srlyn and nylon are two types of coating material available. Nylon coating has a lower cost and during the molding process, it is more forgiving than Surlyn. It should remember to dip the core into latex material to protect the nylon from cracking.
The three primary factors must be kept in mind during the designing process. These factors are durability, scoring, and sound. The durability of pins can be increased by using a multi-piece core and strong coating.
Scoring and sound both are produced by the bowler’s preferences and are majorly controlled by the raw material used in the core. The primary purpose of the bowling pins is to fall over. If pins do not fall over, the game loses its interest.
The sound of pins creates an aura in the bowling game and that is created by wood bowling pins. No other material except wood will be able to create this amazing sound of bowling pins.
So, bowling pins play a major role in the bowling game to produce a high score and create a thrilling and exciting aura during the game with its falling sounds.
