Hardwood Flooring Manufacturing Process

This transcript explains the process of manufacturing hardwood flooring, from drying the wood to applying varnish.

Drying and Cutting

  • Workers stack freshly sawn wood on racks in a large dryer.
  • The moisture content of the wood is reduced to 7% over a period of 10 days to a month.
  • After drying, workers cut the wood into standard sizes using an optimizer that calculates the most efficient use of each plank.

Molding and Sorting

  • A machine called a molder carves tongues and grooves into each piece for easy assembly.
  • Workers check frequently to ensure that the pieces fit together snugly.
  • The pieces are sorted by grade based on quality and color variations.

Finishing

  • The prefinished flooring runs through a sander to prepare it for varnish.
  • Up to eight coats of varnish are applied, with some containing wood stain for certain finishes.
  • Ultraviolet lamps dry each coat in just a few seconds.

This transcript provides an overview of the manufacturing process for hardwood flooring. It does not cover installation or maintenance.
