Design Tip
To save money on HDPE components, minimize the number of part setups, inspection dimensions, or strict tolerances, and avoid deep pockets with small radii.
HDPE
HDPE is a high-density polyethylene known for being lightweight, having low moisture absorption, resisting chemicals and corrosion, and possessing high strength.
It is ideal for use in orthotic and prosthetic devices, water storage, and tanks.
