Abstract:
A method of producing a plastic product having a microstructured outer surface, utilising an arrangement for moulding plastic products, said arrangement having at least two mould parts movable towards and away from each other, a predetermined volume of a viscous polymerisable plastic material being supplied to a cavity formed between the mould parts, after which polymerisation of the plastic material occurs and, after said polymerisation of the plastic material, the mould parts being caused to move apart from each other to allow removal of a finished plastic product the outer shape of which conforms to the inner shape of the cavity produced by the mould parts, characterized in that said viscous polymerisable plastic material is supplied to the cavity around a hole pertaining to the finished plastic product, and in that said viscous plastic material shall be distributed in a direction from said hole towards the peripheral edge area of the plastic product.
