The nature of dry film lubricants means they can be used in a variety of ways. The most obvious is their ability to slide over or under some other item much more easily, making the coating suitable for window channel mechanisms, gears, piston, shears, scissors and many other items. They also have good torque control characteristics for fasteners as well as the ability to reduce surface friction. They can be used to reduce noise due to allowing a more smooth movement or flow of parts together, and can also reduce temperature build up.
High-performance dry film lubricants combine the functionality and performance of the fluorocarbon with advanced engineering organic materials such as polyesters and epoxies to provide unique and highly versatile combinations of properties, resulting in a wide range of uses in domestic, industrial and automotive applications.
The resulting tough coatings can function in environments where traditional lubrication fluids would suffer with viscosity changes across temperature ranges.
Dry film lubricants (DFL) come in many guises, the most common to the general public is Teflon®.
The key feature to remember with cookware is the property you need is none stick. To achieve this the material made by this industry contains in general a highly loaded concentration of a suitable material such as PTFE at the surface. None stick (release) should not be confused with low friction coating, most industrial (none cookware applications) are looking for low friction coatings.
In the low fiction form a polymer matrix, normally epoxy or polyester, is combined with a material such as PTFE or MoS2 in such a way that the low friction additive is uniformly dispersed throughout the coating, giving it the ability to continue to function should it wear and to continue to provide constant properties. The resultant coating is (once cured) dry to the touch yet very slippery.
The dip spin process involves placing the items to be coated into a perforated basket, the basket is then submerged into a tank containing the coating material, the basket is then removed for the material and then spun at a relatively high rpm to expel excess material. The planetary motion or tilts mechanism is designed to re orientate the parts during the spinning cycle so as to release coating material that would otherwaise be trappped in recesses etc. This then reduces the levels of ressess infill that would otherwise be preset in a standard dip spin coating process.
Parts can be processed using automatic CNC programed robotic equipment, this may require initial investment in bespoke tooling.
Parts processed with manual input, generally means reduced capital outlay on bespoke tooling.
