Class Code: 3336
Per NCCI's Scopes Code Description:
Code 3336 is applied to insureds engaged in the operation of a type foundry where type founders design and produce metal type for hand composition. Pig lead or brass received from others is melted and poured into small pigs to be used in casting machines. The molten metal is forced into the type die where it is solidified by a water cooling system around the die itself and is automatically trimmed and ejected from the machine. The classification contemplates the machining and engraving of the dies utilized in the casting operations as well as sorting, inspecting and packaging the type.
Code 3336 additionally contemplates metal casting manufacturing by the lost wax process. The process typically begins by pouring liquid wax into molds. The wax is cooled and the resultant wax cast is removed from the original mold. The wax cast is then dipped into and coated with a material such as silicone silicate. After drying, the coated wax article is placed into an oven, causing the wax to melt and run out. Molten metal is then poured into the remaining mold to form the metal casting. The metal casting is machined as necessary.
