The part substance is a significant element in how clean that a component can be. Some substances will obviously create particles, and whether the specification doesn’t take this into consideration it’ll be challenging to fulfill with the specification.
Cast aluminum is a favorite material for stamping components in the automotive sector. Because of many different factors which occur throughout the manufacturing process and on account of the character of cast aluminum, the machining components will continue to create particles as soon as they’ve been produced.

These little aluminum particles are impossible to get rid of. If a specification requires all these particles to be removed, it is going to be almost impossible to correctly meet it.
A component may fail if a large enough particle of metal isn’t eliminated, but it could possibly be unaffected if a much bigger particle of some other substance is present.
Prior to producing the specification, the producer must know which kinds of particles will be current in their role and also how they will influence the functioning of the part.
But if on precisely the exact same part, a 250 micron bit of silicone or a different substance won’t cause the component to fail, then the producer should ensure that the specification claims that no metallic particles of over 250 microns could be present, instead of no particles whatsoever over 250 microns.
It might appear plausible to remove all particles within that dimension, but different substances respond differently and it might be unnecessarily wasteful and time consuming to concentrate on eliminating all of the contaminants if they’re irrelevant to the operation of the part.
Stamping components are usually tested in a lab, under laboratory conditions. The outcome is extremely precise testing, however, it isn’t repeatable under factory conditions generally.
