摘要:
A process for producing a coupler and an improved coupler are provided. The process produces a coupler by constructing a mold that is a replica of the coupler and is constructed from a plurality of mold components that are selected and assembled to form a mold having the shape of the coupler. The mold components may include a front mold component section that forms the head of the coupler, a rear mold component section that forms the shank of the coupler, and, optionally one or more shelf components forming a shelf of the coupler. The front, rear and shank mold components may themselves be made from a plurality of mold components that are assembled together. The mold is formed from a consumable material, coating with a heat resistant material so that the assembled mold components are within a mold volume, and molten metal is added to the mold volume.
