The Dean Group do not just offer investment castings or lost wax castings, the range encompasses commercial grade investment castings, sand castings and die castings.
As part of their pro active sourcing policy they are now able to source quality extruded parts in both aluminium and brass. Because extrusion has a relatively low labour content, savings over UK production are not as significant as with investment casting; however, if there are subsequent processes involved, drilling/ tapping of holes, cutting to length etc, significant savings are still possible.
This rule applies generally to all the process they source; the more added value that can be applied, the larger the savings. This is particularly true with investment castings where parts could be post machined, electo polished, mechanically hand polished, plated and assembled.

How good are the tolerances on the commercial grade castings compared to the premium grade?
The commercial grade investment casting tolerances are more akin to sand cast tolerances, but the process control and process variation are much better. You also don't need draft angles as the tooling is made in the same way as for investment casting; the wax part releases from the tooling as it cools.
