DFM - Design for manufacture

 

As an important part of my service to help clients take their products from concept to manufacture I carry out a comprehensive exercise in designing the parts of a product ready for manufacture. This is done with computer analysis, testing, engineering data and production samples checking.

I cover several manufacturing methods and materials, such as injection moulded, vacuum formed, fabricated and cast plastics, sheet Aluminium and steel, Aluminium, zinc and steel die and gravity castings, wood, plastic and Aluminium extrusions and the like.

The engineering data, such as tolerance specifications, is specific to each type of materials and the manufacturing method.
