NICKEL SHELL SURFACES
MAT FINI SHED,
IN MONO– OR DOUBLE-GLOSS.
In order to lend a very natural character both to the surface of the nickel shells and to the ultimate product, the KRÜTH company offers a subsequent finishing step. The structure in the nickel shells can be assigned differing gloss values in the crests and the valleys to make the replication in the product even more authentic and to increase the reliability of the process. Over and above this, the finish for the engraving, either in mono- or double-gloss, offers a more homogenous impression, with higher quality visual appearance in mass-produced items.

FINISHING WITH CHEMICAL NICKEL
LIFE INSURANCE FOR MOLDS.
Even perfect engravings can be improved in regard to their physical properties and thus how they respond in production operations. The goal is to keep the quality of the mold’s surface uniform across the entire production cycle. KRÜTH offers two different NiOn coatings for this purpose. The protective nickel layer is applied chemically to the component, at uniform layer thickness.
Both types of coating enhance production reliability and the wear protection of the mold surfaces. This supports uniform quality across the entire batch. Both processes are reversible. Should it be necessary to remove the coating completely from the mold, then this can be done at KRÜTH.
Coating of dimensionally stable construction
With a precise coating in NiOn200, a thickness up to 100 μm can be achieved evenly with no edge buildup. The coating can be applied over a large surface area or only in parts of the mold. The tools are provided with a high adhesion Coating to the surface.
Coating of cooling channels for new tools
Cooling channels tend to corrode resulting in the cross section of the cooling channels reduced. This reduces the cooling capacity to zero. NiOn200 is used to prevent the cooling channels from corroding on new and existing tools.
This coating features improved protection against and reduction of friction. Thus optimum ejection properties for the mold are put in the foreground. This anti-stick finish is a nickel dispersion layer with uniformly distributed, non-metallic PTFE particles embedded in its matrix.
NiOn200 is used whenever there are exceptionally high demands in terms of wear protection. Thanks to the nickel-phosphorous layer (NiP) applied here, the mold’s surface is extremely tough and withstands both wear and corrosion. This can significantly increase the lifetime during production.

THE ANSWER TO MOLD ENGINEERING.
To achieve a perfect cavity bleeding system, Porcerax II® offers an air-permeable steel. Its uniform microporosity lets air and gas escape through the mold itself. Venting problems, flow lines, gas fires, insufficient filling and the associated formation of burrs can be minimized by using Porcerax II® and even eliminated completely. The sintered material itself is noted for its great strength and hardness and good load-bearing capacities. It can be utilized as an ideal factor in process optimization.
