Abstract
This invention relates to a surface finish manufacturing system and process and more particularly, but not exclusively, to a contrast surface finish manufacturing system and process for producing boards with a wood texture finish. The surface finish manufacturing system comprises a top layer and a bottom layer where part of the top layer is removed to expose part of the bottom layer.
Claims5
A surface finish manufacturing process comprising the steps of:
- extruding a bottom layer onto a surface of a board and extruding a top layer onto the bottom layer, wherein the top layer comprises UV-resistant material and the bottom layer comprises an opaque composite material;
- and
- removing part of the top layer, or part of the top layer and part of the bottom layer, to form a wood-grain finish on the surface of the board with part of the bottom layer exposed by the removal of the part of the top layer,
- wherein the top and bottom layers are configured to produce a combination of abrupt and gradual transitions in colour, texture, and pattern on the surface of the board.
