Unfortunate Cases from Reality
The following cases illustrate the need to specify quality requirements properly. Often it is not enough to do "as usually", because when problems occur, the normal goodwill between business partners may soon vanish and liability becomes issue number one. Only by completely defining quality and inspection requirements will you safeguard your company's position.

 

"The situation arose, because nothing was agreed about the quality or the inspection between the engineering company and the foundry."
Fax Enquiry

An inquiry came to a foundry per telefax. The drawing was messy, but nevertheless the foundry made an offer and got the order.

Later, it was revealed that the drawing the order referred to, further referred to quality documents and requirements that the foundry did not know before, and had not taken into account in calculating costs. Costs were remarkably increased.

The foundry should have offered the castings with their own quality documents sent with the quote, specifying that other documents do not apply without agreement.

 

Designation

An engineering company ordered disc castings for paper mill refiners of martensitic stainless steel.

A disc in a refiner fractured in use, destroyed the machine and flew through the roof of the paper mill.

In investigation it was found that a gross manufacturing negligence had happened in the foundry. The disc had not been heat treated at all.

The engineering company sued the foundry and claimed for damages, but lost the case because the material designation was wrong. In the drawing there was a designation "AISI 410", which is a wrought-material designation, instead of CA-15 (the perfect designation: ASTM A 743M Grade CA-15).

The court decided that the demand for heat treatment (specified in the standard: ASTM A 743M ) does not apply and was not an agreement.

With the help of CastSPEX, this situation could have been avoided by selecting the correct material grade from the beginning.

CastSPEX prints automatically perfect and correct designation.

The Front Axle of a Truck

Cracks were found in critical castings in a truck front axle assembly.

This was a major problem, because the castings were useless due to bad quality.

The situation arose, because nothing was agreed about the quality or the inspection between the engineering company and the foundry.

There were no quality documents or requirements. The system designer and the quality department in the foundry had no idea about the quality requirements, and thus made no attempt to improve the quality.

Had CastSPEX been used, accurate quality requirements would have been easy to define.
