    After being pressed under high temperature, internal of floor board core materials contains strong internal stress, a period of conditioning is needed to release the stress and moisture besides heat distribution to stabilize the core materials and further control floor board’s warping and increase bonding strength.

  • 9. Solid Wood Top Veneer Selection

    9. Solid Wood Top Veneer Selection

    The requirement of solid wood engineered flooring’s veneer is very high, not only decorative effect, relatively higher rigidity, density and dimension stability are needed. As multilayer solid wood engineered flooring is used mostly in dry environment, hence dimension stability is essential; moisture content of wood veneer; veneer’s moisture content is controlled under 12%, depending on wood species and environment’s temperature and humidity.

    In order to prevent veneer dampness or fracture due to dryness, solid wood engineered floor board veneer’s precious wood materials are selected by professionals, insect infested and decaying wood, wood with bubbles, dead knot, fractures and other defects, are disposed of, selected woods are then graded according to grains and color difference followed by marking of loose and tight surfaces before further processing and made into slab boards.

  • 10. Formation Of Slab Board

    10. Formation Of Slab Board

    After cutting the edges of core materials, selected veneers are then applied with eco-friendly adhesive NIRO3 to stick on core materials, then the assembled slab boards are heat pressed with hot press machine to form multilayer solid wood flooring slabs; hot press parameters such as temperature, time, pressure must complement with hot press technology to fulfill the requirement of product quality.

    Solid wood multilayer veneer is structured by unique cross-grain arrangement to change wood fiber’s anisotropy, improve limitation of dry shrinkage and wet expansion and reduce core’s warping after being adhered to veneer.

  • 11. Slab Boards Conditioning

    11. Slab Boards Conditioning

    After the core boards are adhered to veneer and heat pressed, internal stress is formed in the slab board, thus a period of conditioning is needed. To balance internal stress, fix it and ensure stability of floor board quality. Problem of finished board warping and deformation can be solved to a great extend and machining precision of further process would be improved.

  • 12. Floor Board Cutting & Grooving
