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.

Claims (8)

1 . 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.

2 . The surface finish manufacturing process as claimed in claim 1 , further comprising removing part of the top layer or part of the top layer and part of the bottom layer of the board by abrading.

3 . The surface finish manufacturing process as claimed in claim 1 , further comprising removing part of the top layer or part of the top layer and part of the bottom layer of the board by sanding.

4 . The surface finish manufacturing process as claimed in claim 1 , further comprising removing part of the top layer or part of the top layer and part of the bottom layer of the board by burning.

5 . The surface finish manufacturing process as claimed in claim 1 , further comprising removing part of the top layer or part of the top layer and part of the bottom layer of the board by embossing.
