Both casting producers and those tasked with casting procurement can specify and assess surface quality and surface texture more accurately with definitive, tactile Scrata Surface Comparators developed by Castings Technology.
Scrata Surface Comparators provide a specimen reference point against which surface roughness can be compared and assessed against the requirements of the designer, much like those used to assess machined features.
These comparators are simple to use, require no power, and measurement results are instantaneously available.
The comparator measures the outermost layer profile height of a material.
Potential specification disputes between suppliers and users can be avoided via this common and recognisable reference point.
Scrata Surface Comparators provide a practical and functional alternative to photographic representation of casting surfaces in standards such as MSS SP-55-2001.
Thousands of comparators are in use internationally on a daily basis.
The durable comparator plates are replicas of relevant characteristics of component surface texture and can be used to ensure compliance between casting manufacturers, specifiers, and independent inspectors.
Typical applications where our Scrata Surface Comparators are used:
Cast surfaces are assessed to determine the machining requirements. This includes the selection of equipment and the use of appropriate media or cutting tools so that the roughness can be eliminated without generating excessive heat by friction, or galling, by the build-up of material on the tooling.
The texture of unmachined surfaces will determine if a component requires rough machining or can be finish machined directly.
Consistency of a surface finish throughout a component is important to begin the assessment of further machining requirements, or where selective material removal is needed to meet the requirements of the customer’s surface finish specification.
For batch consistency, a statistical analysis of the measurement of roughness in a sample of components which have been selected at random from a batch.
