PA6G Cast Tube (Cast Polyamide 6) is a high-performance cast engineering plastic tube offering high mechanical strength, excellent dimensional stability, and superior wear resistance. Compared to extruded PA6, it features lower internal stress and more stable performance under variable load and temperature, making it ideal for thick-walled bushings, bearings, rings, and large CNC-machined components.
What is PA6G Cast Tube?
PA6G Cast Tube is a cast engineering plastic manufactured using a polymer casting
process. Compared to extruded PA6 tubes, it offers higher stiffness, improved dimensional
stability, superior wear resistance, and lower internal stress.
These characteristics make PA6G Cast Tube particularly suitable for thick-walled components,
heavy-duty bushings, and precision-machined parts exposed to continuous load and demanding
operating conditions.
