 |  | | New in the HASCO range are the Z412/... MSO2 coated ejector pins with cylindrical heads according to DIN ISO 6751, known especially in Die-Casting. They are made from hardened hot work steel 1.2343 and nitrided prior to coating, and are additional to the Z41/... ejector pin range. Availability: ex stock, in a wide range of sizes.
Molybdenum is well known as an alloying element reducing abrasion.
This characteristic element is bonded firmly to the ejector pin by a thermochemical coating treatment. The good tempering properties of the ejector pin core material is approx. 600°C.
With a black glossy oxidation layer for the protection of steel surfaces, a number of positive effects are obtained which result in increased productivity and reduced maintenance. The dry-running features are impressive and exceed most of the known coating alternatives. The thin coating layer is fixed solidly to the plasma nitrided surface of the core and does not loose colour or create abrasion harmful to the mould tool.
In combination with the new HASCO special grease A7002/40 the endurance and therefore maintenance intervals are extended further, offering a safe protection against corrosion. Very thin application of the grease creates a film that remains intact without gumming. The outcome of this is further improvement of the tool life and even longer service intervals.
This silicon-free grease is optimized for Plastic Injection and Die-Casting
applications and withstands temperatures of 1400°C with remarkable smooth
running properties. By very good adhesion of the white lubricant on the oxidized hydroplane, abrasion and dirt are not transported to the cavity.
