How much resin do I need for a simple injection moulded extrusion?
How much resin do I need for a simple injection moulded extrusion?
(OP)
I am looking for some multiplier to help ensure I request the proper amount of resin for a part run. The material has various colorants added.
I have the crossectional area of the part/die and I know the length of my extrusion. With this I can calculate the volume of plastic making up my part. How do I account for losses in the manufacturing process (mixing, heating, drool, whatever, ...)?
Would it be reasonable to add 5% to the volume of my parts, or should it be more like 25%?

What does "injection moulded extrusion" mean? From the description it seems you mean extrusion.
