Abstract
An improved plastic knuckle pin for a coupler on a railway car and a method of making the improved plastic knuckle pin whereby the improved plastic knuckle pin has a substantially uniform material matrix and the method of making the pin increases uniformity in the material by increasing the surface cooling area which decreases air and moisture pockets in the material during the molding process.
