What is meant by "dosing" in the context of injection moulding?
mo explains: Dosing is a way of combining two or more components in the right ratio. The great benefit of plastic is its versatility and flexibility. By altering ingredients and additives, you can create precisely the right compound for a given application – changing the material’s mechanical properties, resistance to chemicals or its colour.
