Matrix and molds for slightly abrasive materials:
In this case nickel teflon is the most suitable process due to its low slip rate that minimizes wear and facilitates unmoulding.
Matrix and molds for very abrasive raw materials:
If the raw material is very abrasive, the nickel teflon would be eliminated so it would not apply.
In this case conventional electroless nickel plating would be the most suitable process.
The lifespan of these moulds will be improved thanks to its high anti-corrosion power, a hardness reaching 1000 Hv, and the possibility of applying up to 400 microns thickness.
For unmoulding, nickel teflon is clearly inferior, even though there is an obvious improvement versus uncoated moulds.
