Face veneered MDF inspection

Face veneered MDF inspection

When inspect the face veneered MDF ,the following checklist should be considered :

1.Face veneer types ,Plain slice or rotary cut ,book matched or slip matched ..

2.Face veneer wood species ,

3.Face veneer thickness

4.Substrate MDF quality ,such as thickness ,water swelling ,density ,internal glue strength,screw holding power  …

5.Glue is water based or ….

6.Single side face veneered or two sides ,if one side ,need balance the veneered MDF to flat

7.MDF Suitable for  laser cutting,veneer lamination or other applications …

8.there is often a crook or bow to the sheet. The natural twist might be in excess of 8 mm

9.The wood  face veneer is not like an artificial surface such as melamine or a laminate. It is cut from the log and therefore has its own unique grain, texture, and colour.

10.The  Grade Veneer is a very high quality grading (typically the best you will see). The surface of the material will be consistent in appearance with no large variations in colour. Small pin knots are allowed and these would typically be only a few mm in diameter. This grade veneer is on the topside of this MDF sheet.

11.The surface should normally be free from open knots and plugs. The material should be suitable for paint / stain or a lacquered finish.

12.There are two different cuts that can be used in veneer production,such as Birch Veneered MDF, Maple or red oak vENEERED MDF .

  • Quarter Cut’ are cut at 90 degrees, producing the effect of a straight grain.
  • ‘Crown Cut’ are sliced through the log, producing ‘Crowns’ and adding more character to the finish (as used on this product).

13.Tolerances:

The manufacturing tolerance for the thickness of veneered MDF sheets include the tolerance for both the MDF and the veneer. The total combined thickness of both the MDF and the veneer  .

14.

  • As wood is a natural product there is often a bow or crook to the MDF, and in some cases a twist. We have measured in excess of 8mm rise between the flat centre of the MDF and the corner. These twists are completely normal. If you are using this product on a laser cutter; these sheets should be strapped/taped to the laser bed before cutting.

15.Veneered MDF is primarily used for internal use only. Ensuring that it doesn’t come into contact with elements such as water, MDF will hold its form in any way it’s used. Cutting and marking with either electrical saws or handsaws are used to your own benefits. Making sure that all edges are sanded smooth after cutting will provide a clean and smooth finish when applying paints. Doing so also prevents any harmful fibres being released from the board. In terms of fixings, screws and biscuit dimensions should be taken into consideration, in order to maintain a clean finish.

16.MDF is made from recycled offcuts, sawdust, wood chippings and from trees not suitable for other uses. Different manufacturers list how much recycled material goes into their products. MDF is considered a green product and environmentally friendly.
