Factors influencing the useful life of a <\/span>O-ring<\/b> can be classified as part-specific (housing design and material selection) and external to the part, such as installation, handling and working conditions, among others.<\/span><\/p>\n

Even if the housing design is correct and the right material is chosen, the service life of the housing will be reduced. <\/span>O-ring<\/b> may be shorter than expected and deteriorate. As a result, if fragments of the <\/span>O-ring<\/b> If they are in process and are also easily recognizable by a machine vision system, then the chances of detecting foreign bodies will increase significantly. \u00a0<\/span><\/p>\n

In this context, it is useful to \u201ccustomize\u201d the <\/span>O-ring<\/b> with a specific color. Nowadays there is a technology that allows the piece to be colored with the color of your choice.<\/span><\/p>\n

There are also surface treatments that significantly improve their performance, such as anti-wear coatings. <\/span><\/p>\n

Other times, due to the assembly of the <\/span>O-ring<\/b>, If the part does not slide effectively into its housing. This can be remedied with a surface finish that is sufficiently slippery and increases lubrication.<\/span><\/p>\n

The treatments mentioned above have in common that they do not alter the elasticity or impoverish the chemical resistance of the material.<\/span> O-ring<\/b>. In addition, all of them, to a greater or lesser degree, reduce the effect of <\/span>\u201cStick-slip\u201d<\/span><\/i> or irregular movement in the displacement of a rod, jerking. <\/span><\/p>\n

However, before applying any coating or treatment, the part must be properly cleaned.<\/span><\/p>\n

CLEANING TREATMENTS<\/b><\/p>\n

The current cleaning processes guarantee that the part is free of any contaminant and do not affect the properties of the material (hardness, working temperatures, color, etc...). There are 4 levels of cleaning:<\/span><\/p>\n
