I'm looking for plastics that are exremely wear and abrasion resistant at 220 F. They need to processed into tube sections that are 12 inches long, with 7.75 inch OD, .325 inch wall. Continuous sections can be cut into shorter lengths. Thanks.
What loads are needed, how should they be applied, and what is the proper approach to use to analyze a pulley? I have a solid model of the pulley and I'm trying to determine if plastic would be appropriate. I've been given the applied torque, hub load, and rpm. I also have the operating...
I heard the argument again that "All voids in injection molded parts are due to trapped air or gas, and not due to shrinkage. Shrinkage causes internal cracks, but not voids". For this discussion, voids are defects that are roughly spherical. Any comments?
I have two plastic round plates (disks)in contact. One is rotating against the other one. (A type of brake application). The wear of the thickness of the plates is uneven. A cross section would show a wavy pattern from the inside radius to the outside radius. Any idea what could cause this? thanks.
