Abstract
A method of producing a plastic product having a microstructured surface ( ), utilizing an arrangement for moulding plastic products. Said arrangement has at least two mould parts ( ) movable towards and away from each other, a predetermined volume of a viscous polymerizable plastic material ( ) being supplied to a cavity formed between the mould parts, after which polymerization of the plastic material occurs. After said polymerization of the plastic material ( ′), the mould parts are caused to move apart from each other thereby allowing removal of a finished plastic product the outer shape of which conforms to the shape of the cavity produced by the mould parts. Said viscous polymerizable plastic material ( ) is supplied to the cavity ( ) around a hole ( ) pertaining to the finished plastic product, and said viscous plastic material is distributed in a direction from said hole ( ) towards the peripheral edge area of the plastic product.
