First, it's important to check each company's processing precision and the range of diameters for which you need processing. Determine to what degree potential partners can guarantee tolerances and surface quality for the dimensions and shapes of the articles you want processed.
An additional criterion for selecting partners is their material handling capacity. Companies that work with diverse materials, such as metals, plastics, and ceramics, can flexibly handle everything from prototyping to mass production. Other key points in determining the reliability of potential partners are whether they have a temperature-controlled environment and whether they've disclosed information about their inspection systems and their past processing track record.
