What's the Ultem CNC Machining?

Before discussing the process of Machining ULTEM, it`s important to understand exactly what plastic machining is.

CNC (Computer Numerical Control) machining is a process in the manufacturing sector that involves the use of computers to control machine tools. In the case of plastic machining, this involves the precise removal of layers from a plastic sheet, rod, tube or near net molded blank.

The early history of CNC machining is almost as complex as a modern CNC system. The earliest version of computer numerical control (CNC) technology was developed shortly after World War II as a reliable, repeatable way to manufacture more accurate and complex parts for the aircraft industry. Numerical control-the precursor to CNC-was developed by John Parsons as a method of producing integrally stiffened aircraft skins.

One of the high-performance thermoplastics that AIP works with is ULTEM: a PEI, or polyetherimide. ULTEM was developed by General Electric Plastics Division (Now SABIC) back in the early 1980s. Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic.

Among other uses, ULTEM is popularly used in medical instrument components, aircraft interiors, missile and defense-related components, electrical insulation parts, and semiconductor equipment components.
