QUALITY CONTROL

 

In the rule ISO 9001 (checking procedure for quality), the term “quality” is the relationship between the obtained result and what we want to obtain.

This sentence premises that it has to exist ever a project, a prevision, a product sample, many tolerances to accept or not the results.

Checking management has the objective to reach quality on the final product, so what we deliver to clients, because ii has to be the same as the client ordered.

Apparently, it is simple to prepare the quality checking procedure, it is sufficient to prepare exactly what the client want. Is it too simple?

 Referred to lighting fixtures and lampshades, we have to see some simple aspects that we meet anytime and we have to resolve.

Which is the exact color of the fabric that we use to mount a lampshade?

Which is the finishing’s level of the products’ surfaces?

On a chromed surface, how many points of discontinuity can be accepted?   There are points that derive from atmosphere dust that can rest on surfaces during chrome plating, it isn’t powder, but little dust. As the chrome companies don’t work in “white” room, these points are unavoidable.

As the white paper for packaging can release visible defects on plated surface, how have to pack these components/items?

The lampshade’s fabric has to be joint at least in a point, because the fabric is flat and the lampshade is a closed volume; it is necessary to close also the covering and there will be closing points. What impact will have them on the lampshades’ surface?

How can we obtain the production homogeneity on different lot, which will be produced for the same client?

 

The list of what we have to check every time is so long and we can talk a lot about that and maybe also for non-compliance received, that nobody thought about and sometimes we weren’t able to know causes.

Who can imagine that a very little glue point in a fixing clamp could cause a damage on a lamp’s chrome surface?

Quality control consists first of all to prevent which and how many could be defects on a product during all working’ steps and provide to operators indications to avoid that these faults compare and at the end check that all is ok.

You have to think that in a lamp there are many components, each one with production cycle of many phases then the defect can be in each component and not only in the lot; if we multiple all for the number of products that Guido Raffaello produces for all clients, this is a checking control idea.

Obviously if we decide to get down of only 1 level, to enlarge the tolerance level, accept a discrete finishing, instead of a an excellence finishing, means to decrease a lot of difficulties and that explain why there is a lot of price difference between an economic product and an excellent product.

The discrete product aren’t so bad, as they cost less and certainly can satisfy requests of many persons, but the excellence is another thing.

A fabric that don’t relax itself during time, a color that don’t change tonality, little defects that don’t exist:

if there are some defects, lamps work the same and issue light, but there is quality difference.

Who don’t like only a lamp that issue light, so a discrete product, but want excellence, has to know that difference between these different products depends from many operations that avoid every defects on final product.

All of that is necessary to satisfy exigent client, the same that don’t choose discrete products, but wants the best, all these customers request to work with Guido Raffaello.
