Positive Die, sometimes known as shelf dies
A technical challenge is to produce dies that have a for in – this means that the material put in the is expected to fill or flow through the cavity. This means for a tool maker to connect the part made with multiple processes and still deliver <0.005mm accuracies.
The Akris group of companies are well known in this area allowing our customers to produce parts that are either final product ready or just requiring minor amount of rework or deburring prior to use.
The materials that are regularly machined for these applications are carbide, powder metal steels ~66HRc
