Grainger and Worrall Designs,Makes, Innovates Your Future

In the past the traditional approach to casting development was by largely trial and error. This would involve producing a casting gating system by a foundry engineer’s best estimate, then if this failed, a second, third etc version would be produced until a satisfactory casting was achieved. 

We apply many approaches to rapid prototyping depending on the product production
requirements. Sometimes a hybridised rapid prototype is best, sometimes full rapid
prototyping is best, our experience in this complex field will add value to your program. Read more...
