Bowling pins are hourglass-shaped equipments used in the game of bowling. It is an indoor game played on a polished wooden or synthetic floor by individuals or teams.
Specifications for making bowling pins are set by the American Bowling Congress (ABC). The most common material used is hard rock maple wood. This wood is hard and durable. Manufacturing a wooden bowling pin involves a series including the lamination processes, cutting, shaping, molding and finishing steps. Gluing blocks of hard rock maple wood into a shape by turning it on a lathe makes bowling pins. After the lathe shapes the pin, it is coated with a plastic material and finally covered with a protective, glossy plastic layer.
Because of the scarcity of suitable wood, plastic and synthetic are frequently used to make bowling pins. Unlike wooden bowling pins, plastic bowling pins are made by a process called thermoplastic injection molding process.
Pins weigh between 1.53 kg and 1.64 kg (3 lb 6 oz and 3 lb 10 oz). Each pin is 38.1 cm tall. Pins have a narrow neck that gradually widens to a diameter of 12 cm at the widest point that is called the belly. The pin then tapers to a base 5.7 cm in diameter. This design causes the pin to fall if tilted 10 degrees.
There are various bowling pin types available, including the Winsom pin and the Brunswick Max, as well as the AMF Sumo, AMF pin, the Brunswick Flyer, the Brunswick mixer, the Vulcan Vultex II, the Brunswick “B” Max, the Brunswick Killer “B”, the Brunswick PBA gold pin, the Brunswick WWF “The Rock” pin, the Brunswick PBA gold pin and the candle pin.
