Many of these parts are manufactured by casting. Liquid aluminium is cast into the desired form. Preformed sand cores within the form provide the desired structure to the part. Modern manufacturing processes ensure low tolerances of the cast parts so that expensive subsequent machining becomes redundant to a great extent.
OKS 111 is based on OKS 110 MoS2 powder, microsize. A natural wax has been added to make it suitable for processing with a spray can. This holds the powder reliably on the sprayed surface and ensures that a dust cloud does not arise during spraying. This wax does impede the depositing of the MoS2 on metal surfaces and evaporates residue-free at high temperatures.
OKS 111 Example of use
OKS 111 is used in the mould and die production of an aluminium works for initial lubrication of the slideways (Figure 1), ejector pins (Figure 2) as well as all the other moving parts of the casting forms (Figure 3). These prepared forms are then stored until they are used.

In the actual production process OKS 111 is used as a universal lubricant. Here too the slideways, ejector pins and all the other moving parts are re-lubricated regularly with OKS 111.
Similarly OKS 111 is used to lubricate the guides and various mechanisms of the production machines.
All three applications have in common that conventional lubricants based on oil can no longer be used due to the high temperatures. A pure MoS2 powder, such as OKS 111, can be used at temperatures up to 450 °C without vapours arising (Picture 4).

Further OKS products for use in aluminium manufacturing
In addition to the applications mentioned above for OKS 111, the entire range of OKS speciality lubricants can be used for the maintenance and servicing of the plants and the plant equipment. Whether as cleaners of electrical contacts, compressed-air or cooling spray for the electrical department, rust removers, cleaners, mounting pastes or greases for servicing and maintenance of machines or also as chain spray for hoisting chains at cranes or fork lifts - there are plenty of possible applications and examples.
