Incoming goods inspection

At MN Kaltformteile, quality assurance begins as soon as goods are received. Incoming raw materials are inspected before being released for production. Each wire coil is visually inspected for transport damage, signs of corrosion and surface defects. In addition, a material sample is taken from each coil.

In our in-house QA laboratory, the samples are tested for tensile strength, elongation and other mechanical properties, amongst other things. Only when the test results fall within the specified limits is the material approved for production.

The incoming goods inspection also covers components that are returned to MN following further processing steps carried out externally. These include, for example, heat treatments as well as electroplating or other surface treatments. Upon return, the components are checked to ensure that the respective defined requirements are met. Depending on the process and component, checks are carried out on, for example, dimensions, surface condition, coating characteristics, hardness or other specified properties.

Incoming goods inspection thus forms a key control point along the entire process chain – from raw materials to components that have undergone external further processing. Deviations can be detected before materials or components proceed to the next process step. This makes incoming goods inspection an essential component of preventive quality assurance at MN Kaltformteile.
