plastic cover material
plastic cover material
(OP)
Hello,
Currently I am designing a plastic cover. It will be mounted on a truck and will be exposed to the environment and possibly hydraulic fluid. the overall volume the part must cover is 2 by 3 by 1 feet. It will be mounted around a pivoting joint at the end or a boom. Its primary requirement is to minimize shock hazards and it needs to be reasonably durable. Part quantity will be around 500/yr. Im considering using a 2 piece cover (parting line to give minimum part depth) using vacuum forming with cutouts for the moving components. The materials I am looking at are ABS and HDPE. Are there any guidelines for determining minimum radius, and maximum draw depth considering sheet thickness and material chosen for this process. I havent designed any plastic parts before so i may be way off in selecting thermoforming. Thanks for reading

RE: plastic cover material
Thermoforming way to go.
Please do it the easy way and talk to a thermoformer. They might even do the design stuff for you.
Materials sound ok, but stress cracking with HDPE and oils may be an issue.

RE: plastic cover material
Rotational moulding or vacuum forming are the two possible processes at those volumes.
If rotationally moulded, you do two together then split them apart after moulding.
