Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
Can you CNC HDPE?
Yes, you can CNC HDPE. High-density polyethylene (HDPE) is a slippery plastic that is moisture and chemical-resistant.
What is HDPE used for?
HDPE is often machined into plugs and seals. It is an excellent electrical insulator that has a waxy finish suited for low-friction applications.
What are the advantages of HDPE?
Advantages of HDPE include good low temperature impact resistance and excellent chemical resistance. It is a high-quality, stiff and durable material that is affordable
What are the disadvantages of HDPE?
The disadvantages of HDPE are that it is susceptible to stress cracking and higher mould shrinkage, and also has lower stiffness compared to polypropylene.
