PEI Plastic Machining Ultem Wear Resistance Stronger Hardness

machining ultem parts

ULTEM is also called PEI ,The exterior is amber and translucent. It is better than PTFE (Teflon),Stronger hardness, good insulation and wear resistance, has excellent machining performance.Generally, 10% or 30% glass fiber is added to increase hardness and wear resistance.Usually ULTEM has three models,ULTEM1000,ULTEM2100 GF10,(10% glass fiber)ULTEM2300 GF30( 30% glass fiber)

In the process of machining UTLEM parts, the difficulty of machining them is,ULTEM2300>ULTEM2100>ULTEM1000.

Machining Pei (ultem) is more difficult than PTFE because of its high hardness.The wear resistance of ultem parts has higher requirements for the cutting tools of CNC machining center.We have calculated that after 3.5 hours of machining ultem, the tool wear is 0.03mm,Therefore, the parameters of machining center should be modified to compensate the tool wear size.

Of course, it is a good way to divide machining Pei into two steps. Rough machining and micro machining.Generally, engineers will reserve 0.5mm machining allowance for micro machining.

It is worth noting that in machining ULTME parts, the stress rupture of the non crystalline plastic structure in ULTEM may be caused, so the CNC machining center should use spray and compressed air as cooling.

Ruiyihang technology has 32 CNC machining centers, 18 CNC turning centers, and advanced machines such as precision milling machines, grinders and laser cutting machines, which can complete milling, boring, turning, grinding, slotting, drilling and tapping. With more than 12 years of experience in machining utlem, an efficient team can provide samples within one week at the fastest.
