In most of these markets, we provide engineered castings that are unique to the application. From exhaust mainfolds to gear housings and rotary joints to diesel engine bell housings, Specialty Castings can deliver one-off prototypes to medium production volumes.

Our niche focus on engineered castings, competitive pricing, and full service provides you with the product you need and the responsiveness you expect.

Using 12 different testing criteria, Specialty Castings offers various forms of mechanical and physical testing to ensure your castings meet your specifications. From ultra-sonic and magnetic particle testing to microstructure and metal analysis, the QA team at Specialty Castings is focused on quality castings.

The ISO 9001:2008 certification (click to view) and ongoing process improvements are used to continually improve our operations and maintain the high level of quality products our customers expect. The testing equipment and procedures used by Specialty Castings QA technicians includes:

  • Ultra-sonic Testing
  • Magnetic Particle Testing
  • X-ray Testing
  • Metal Analysis – Carbon/Silicon
  • Microstructure Analysis
  • Brinnel Hardness
  • Mechanical Testing
  • Dimensional Layout
  • Process Control System

Using Inductotherm and Brown Boveri melting furnaces each capable of up to two tons per hour, Specialty Castings pours gray and ductile iron castings ranging from 1/4 lb to 200 lbs. The Hartley controlled green sand molding system provides for a broad range of casting sizes and configurations using matchplate, squeezer, and cope and drag pattern types.

The core making capabilities include wood, metal, or plastic core box air set on a double head Harrison shell core machine. Finishing is applied to each casting using a wheelabrator blast unit, grinding stations, and didion drum.
