Profile: J W Singer is a manufacturer of sprinkler bodies for the fire protection industry. We are an ISO 9001: 2000 certified company. We provide engineering design, high pressure die casting, and finishing & machining services. Powershape by Delcam is a 3 dimensional software system used as a wire frame generator or a solid modeler. This system is also useful in ensuring that the design is correct before the die steel is cut, which minimizes the errors that might otherwise be found after the tool making process has began. We also manufacture brass pressure die castings with a standard shot blast finish. This process cleans and brightens the surface of the casting, leaving a finish that can be painted or plated without any additional operations.
