Tips for cold bending of sheet metal
Plastic deformation is the transformation of materials into a solid state that can take place at different temperatures between cold and hot.
But, when it comes to plastic, how can you distinguish cold deformation from hot deformation?

"Solutions to reduce sliding and rolling friction"
Friction is the force generated by the contact between the surfaces of two bodies that opposes the motion of one towards the other. Different forms of friction can be identified depending on the physical and kinematic conditions that come into play. In this article we will focus on sliding and rolling friction. How do they work? How can the related wear phenomena be avoided?

"Use of silicone oil"
When we talk about mechanical connections and movements, the common denominator is the lubrication of the components that concern them, with silicone oil or silicone grease, in order to operate correctly.
Lubricants for Noryl plastic
Noryl plastic is an increasingly common material used in various industrial fields. As an alloy between polymers composed of polyphenylene oxide and polystyrene, it is excellent in electrical components or in use at high temperatures. This latter aspect obviously opens a parenthesis regarding correct lubrication.

How to avoid iron oxidation
What we commonly call iron oxidation is actually an electro-chemical phenomenon. A very particular phenomenon yet also very simple and elementary in its mechanism, which involves the transfer of the smallest electric charges (the negatively-charged sub-atomic particles called electrons) from the area of an atom of a certain element to the area of an atom of a different element.

Which lubricant for your bearings?
If you design mechanical components and deal with bearings on a daily basis, it is important that you have a thorough understanding of the lubrication conditions and the characteristics of the lubricants to be used, in order to improve performance and extend the life of your project.
The dynamic viscosity of bearing grease and its adhesiveness, for example, are two very important characteristics that not all lubricants have to an extent suited to their intended use and which should, in any case, be properly balanced.
The tribosystem and friction variables
Friction or, as it is more correct and precise to say, frictional force, is generated by the surfaces of two bodies, whose motion opposes that of the other. The direct consequence of friction is wear (loss of material) of moving bodies - a consequence that can be countered (or at least reduced) by applying the right type of lubricant.

high voltage, low wear
It is essential to prevent the formation of the electric arc in the high voltage circuit-breakers operating in the transformer substations. For this purpose, a lubricating grease can play a key role, always if formulated starting from the actual characteristics and operating conditions of the circuit-breaker.

Cushioned hinges and damping lubricants
In more and more items of furniture in the home, whenever we close a drawer or a door, they travel along 90% of their stroke at the speed we set, only to slow down and close in an apparently "mechanical" way. These cushioned hinges and their controlled coefficient of friction are also thanks to special damping lubricants.

"Seals always at the top"
The rubber-steel coefficient of friction is among the most common in the industrial sector, which is why sealing rings and gaskets are frequently damaged.
At the basis of these damages there is certainly an inappropriate lubrication, in terms of procedures or products, which can compromise the functionality of the components from the initial phase of use, not necessarily in the long term.
