Frequently Asked Questions (FAQ)

Ultem offers several advantages for CNC machining, including high strength and stiffness, excellent dimensional stability, resistance to chemicals and high temperatures, and good electrical insulation properties. These characteristics make it suitable for a wide range of applications, such as aerospace, automotive, medical, and electronics.

Yes, Ultem can also be processed using other manufacturing methods like injection molding, extrusion, and thermoforming. However, CNC machining offers a high level of precision and design flexibility, making it an ideal choice for complex and custom parts.

CNC machining can create a wide range of Ultem parts, from intricate components for medical devices to large structural components for aerospace applications. Examples include gears, housings, brackets, seals, and electrical insulators.

When CNC machining Ultem, it is essential to use sharp cutting tools to minimize the risk of delamination or material chipping. Proper coolant use and adequate chip evacuation also help ensure optimal surface finishes and dimensional accuracy.

CNC machining and injection molding both have their advantages and limitations. CNC machining is more suitable for low- to medium-volume production runs, offering higher precision and design flexibility. Injection molding is better suited for high-volume production of complex parts, providing cost-effectiveness and consistent quality across large batches.

Common finishes include as-machined, bead-blasted, and polished surfaces. Specific surface finishes may be required for certain applications, such as medical or food processing equipment.

Ultem is available in different grades with varying properties to meet specific application requirements. It’s essential to consider factors such as mechanical strength, chemical resistance, thermal stability, and regulatory compliance when selecting the appropriate Ultem grade. Consulting with material experts or CNC machining specialists can help you make an informed decision.

Yes, Ultem parts can undergo various post-processing operations, such as painting, coating, or heat treatment, depending on the specific application requirements. It is important to select the appropriate post-processing methods to ensure the part’s performance and durability are maintained.
