PA6G Cast Sheet (Cast Polyamide 6) is a cast engineering plastic sheet offering high mechanical strength, excellent dimensional stability, and very good wear resistance. Compared to extruded PA6, it provides higher stiffness, lower moisture absorption, and more stable performance under variable load and temperature, making it suitable for CNC-machined industrial components.
What is PA6G Cast Sheet?
PA6G Cast Sheet is an engineering polyamide produced using a casting process rather than
extrusion. Compared to standard extruded PA6 sheets, it offers higher stiffness, improved dimensional
stability, lower moisture absorption, and superior wear resistance.
The cast structure results in reduced internal stress and more stable dimensional behavior, making
PA6G Cast Sheet one of the preferred materials for precision CNC-machined industrial components
subjected to mechanical load and continuous wear.
Engineering advantages of PA6G Cast Sheet
- Higher stiffness and strength than extruded PA6
- Excellent dimensional stability under variable load and temperature
- Very good wear resistance for sliding and rotating components
- Lower moisture absorption compared to standard PA6
- Precision CNC machinability for tight-tolerance parts
- Low friction behavior suitable for bushings, bearings, and gears
- Lightweight alternative to metal in many mechanical applications
Typical applications of PA6G Cast Sheet
- Industrial bushings and bearings
- Gears, couplings, and transmission components
- Rings, sliders, and wear plates
