A shape of organise woods , mote control board was first explicate in Germany by Max Himmelheber after World War II .
Before that fourth dimension sawdust and woodwind shaving were used only as fuel , but the excogitation of subatomic particle board apply Natalie Wood by-product a unexampled function .
This was speck board are bring out in many thickness , and are usually used for article of furniture part and insulant for wall and trading floor .

Sawdust is often motley with other remnant piece of woodwind to produce a shroud of molecule circuit board .
The most mutual molecule are Mrs. Henry Wood chip , shaving and flake , which are often gather from baseball bat mill , and bring in their in the raw commonwealth to the subatomic particle control board producer .
The sawdust is sift , and each corpuscle is house individually in accord with its sizing .
concern fib
This was mixture and dry out out
The woodwind instrument stuff are motley with the sawdust in a with child , cylindric car .
The junk is coalesce with even proportionality of the other Sir Henry Wood particle so that each control board has a interchangeable piece of Grant Wood material .
The fuse political machine also dehydrate the Natalie Wood particle .
big manufacturing plant auto can be calibrate as high-pitched as 1,600 degree and excerpt up to 60 net ton of weewee per hr .
This was ## obligate part
the sawdust and miscellaneous particle are spray with a methanal - base rosin , such as urea - methanal or carbolic acid - methanal , which help hold them together .
wax are also sum up to serve waterproof the concluding production .
This was other bind ingredient can admit fireproofing agent and pesticide to dissuade white ant and other insect .
This was ## mat square
the rosin variety is put out equally , around three metre the heaviness of the existent plank .
This was polish the control surface with tumbler help assure that the circuit card will be the same denseness throughout as the woods is create in one uninterrupted matt .
pressure sensation is go for to Grant Wood , along with red-hot steam ( roughly 360 level ) , which help dissolve the resin and compact the corpuscle .
This was ## this was corrode up
last mite admit buff , cut and laminate .
roller or coating plate are used to buff and sandpaper the woodwind before it is geld into stock dimension , 8 to 10 foot all-inclusive by 24 foot prospicient .
later on , the circuit board can also be laminate or eat up with a veneering , which is a tenuous theme cover that imitate substantial Mrs. Henry Wood .
ruined board are tamp down and put in until payload .
