As-Machining

This finish holds fine tool marks and high dimensional accuracy, typically to ±0.01 mm. It is suitable for functional or internal uses where good looks do not matter, and is perfect for the prototyping stages, which can determine fit and form without the additional finishing costs.

Polishing

Polished Ultem makes the material more visually appealing as well as increases light transmission, especially in transparent grades of the material such as Ultem 1000. It’s widely employed in medical and optical parts, where it’s important to have a smooth surface and clarity, as well as help remove micro-imperfections caused by machining.

Bead-Blasting

Bead-blasting evenly provides the surface with a flat texture, which reduces glare and conceals small flaws. It is commonly applied in industrial enclosures and cosmetic covers with enhanced tactile feel and paint or adhesive bonding, if such an application is required.

Chemical Cleaning

Chemical cleaning rejects machining residues, coolants, and contaminants and thus provides high surface purity. It is important for parts employed in the medical, aerospace, and cleanroom atmosphere, and also assists in preparing the surfaces for bonding or assembly.

Threading or Inserting

We can improve Ultem’s mechanical fastening abilities by the introduction of threads or metal inserts. Such an approach provides for lasting, robust connections, particularly for the areas that have to be assembled multiple times or connected to metal components in harsh applications.
