Device and method for producing a moulded body having microstructures

摘要

The invention relates to a method and a device for producing a moulded body having microstructures from moulding material. The method for producing a moulded body having microstructures on a carrier out of moulding material is effected by inputting a moulding material into a container (10) comprising a mould cavity (14), wherein at least one micro-structured mould (12) is provided in the mould cavity. Furthermore, the centrifugation of a container (10) is carried out until the moulding material has completely entered into the structure of the mould (12). Thereafter, the curing of the moulding material is carried out to form a moulded body having microstructures, which is then removed from the mould (12) and the container (10). A container (10) is provided into which the mould (12) has been inserted, and the container (10) is connectable to a centrifuge wherein the container (10) comprises a mould cavity for receiving the moulding material wherein the mould cavity (14) comprises at least one micro-structured mould (12).

1. Device for producing a moulded body having microstructures made of a moulding material, comprising:
a container; said container comprises an upper part and a lower part connected to each other, said upper and lower parts form said mould cavity for receiving said moulding material; a mould, said mould includes a micro-structured surface; said lower part of said container includes a mould receiving means and said mould having said micro-structured surface; said lower part of said container is located further away from said rotational axis of said centrifuge than said upper part of said container; said upper part of said container comprises a stamp element and a receiving means for said stamp element; said stamp element comprises a micro-structured surface; said mould having said micro-structured surface being spaced apart from said stamp element; said moulding material resides between said microstructured surface of said stamp element and said micro-structured surface of said mould; said container mounted to a rotatable centrifuge and said container is rotatable about a rotational axis; said stamp element is movable in the direction of said mould of said lower part of said container by means of centrifugal force when said container is rotated producing a moulded body having a first surface formed by said micro-structured surface of said stamp element and a second surface formed by said micro-structured surface of said mould, and, said first and second surfaces of said moulded body are spaced apart from each other.
