Many model makers have the equipment and are accustomed to handling the entire engineering process from idea to product. In addition they help perform strength and/or stability calculations, the detailing and conversion activities. Using the latest techniques right from the design stage means that the end products will meet the most stringent production requirements and the costs will remain low. Thorough analyses are part of the design process, of course. That design process may involve single cast items, forms, moulds and products, or it may involve complex composite items.
