Minkor

Defy the corrosion - not the tool!

Corrosion resistant tool steel and ease of machining have long been incompatible bedfellows. That's all in the past, now we have MINKOR®. Better boring and fast milling: made possible with MINKOR®. Deep cooling bores and complex milling work can now be done in almost two-thirds of the time. When using corrosive plastics, the selection of a resistant mould making steel is crucial to the service life of the mould.

For mould frames and inserts - it's well worth trying!
