Quality checks

A comprehensive quality management after most modern standards guarantees a remaining product quality on highest level.

Initial sample checks, incoming inspections, initial sample approvals, in-process inspections and - if necessary - final inspections are implemented. Using the principle of operator-self-inspection program (OSI) these checks are minimised to realise cost optimisation. Additional checks are only used where necessary to supplement the OSI in case of special requirements.

Damages and defects in the cast material are recognized by visual inspections at all stages of production, allowing the affected units to be sifted out of the manufacturing process and withdrawn from further use.

Damage includes for example scratch marks, blemishes or material fractures, which can occur through handling during manufacture and internal transportation.

Surface defects in the cast material, such as areas of porosity, shrink holes, cavities (hollows) and material shortage caused by insufficient mould filling or moulding, can occur during the casting and cooling process.

In addition to the customary analogue and digital testing and measuring equipment in standard use, Quality Assurance has access to other devices and facilities used to carry out further inspections.
