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!
MINKOR® — VarioPlan3
Semi-finished product for frame and insert
6-sided fine-milled with bevel and radius
Dimensions as required
For jigs and machines - strength needed, not corrosion.
MINKOR® - Properties, technical data and processing:
- tempered through and through to approx. 300 HB (950—1100 N/mm²)
- good heat conduction (21.6 W/m²K at 20 °C; 23.2 W/m²K at 50 °C; 24.9 W/m²K at 350 °C)
- welds very well (pre-heat to 100 °C)
- corrosion resistant (comparable with 1.2085 / 1.2316)
- dimensionally stable
- significantly tougher than others
- (notch impact energy ISO V-sample: MINKOR: 10-12 Joule; 1.2085 / 1.2316: 4-6 Joule)
- drills very well, even with cooling bores
