HDPE Manufacturing in colour 2

[oatmeal]

A sign has been specified to manufactured in HDPE, can this be manufactured in one piece with multiple colours or does it have to be individual and mechanically joined?

Either is possible if you have enough money.

Multi colour HDPE can be done by co extrusion, twin barrel injection or lamination.

Would be convenient and cheaper to make the sign in one piece out of HDPE and then put a sticker on it to make the sign. If it's for outdorr use then you need to be sure to consider that the HDPE will be degraded by the UV light and so you need to use a grade with appropriate stabilisers against UV light.
