The lost wax/investment casting process at Lost Wax Development converts metal in a single operation to precision engineered components with a minimum wastage of material and energy and subsequent machining. It has a versatility approached by few other metal forming processes. Intricate or re-entrant contours can be incorporated. These features offer great freedom of design; this versatility extends to materials, since virtually any alloy can be cast.
The benefits of the process operated at Lost Wax Development Ltd., may be summed up in four words: accuracy, versatility, integrity and finish. Accuracy and versatility stem from the use of a one-piece die without a joint line or the need for draft angles. These features not only give rise to a component that is aesthetic and uniform; they also allow the process to give, on a regular basis, consistent and repetitive close tolerances, intricate and re-entrant contours (many impossible to create economically by alternative manufacturing techniques) and competitive cost ratios.
Casting integrity is an important feature of the process and we have a long history of serving the most demanding sectors of industry. Other advantages arise from the high degree of dimensional accuracy, + or - 0.10mm per 25mm with improvements up to + or - 0.08mm per 25mm and the excellent surface finish that can be routinely achieved, typically 1.5 to 3.2 microns with improvements up to 0.8 microns.
