A rotating dual-cavity press preforms real wood sheets and bonds the core in one cycle to improve adhesion, surface quality, and soft touch.

Epoxy-impregnated carbon or basalt fabric layers let plywood cargo floors stay strong and damage-resistant while reducing weight and fuel use.

Hydrothermal forming and controlled drying shape corrugated veneer continuously, cutting wood use while enabling auxetic honeycomb cores.

An inclined moving support lifts the clamped workpiece off the bearing surface, preventing drag abrasion while maintaining precise positioning.

Partially delignified wood veneer impregnated with polymer thermoforms into double-curved parts with lower weight, fewer tears, and more predictable shaping.

Thermally cured acrylate or polyester wear layers improve panel transparency, scratch resistance, relief depth, and noise behavior.

Thermally cured acrylate or polyester wear layers improve panel transparency, scratch resistance, deep relief, and reduce clicking sounds.

Thermal curing of acrylate or polyester wear layers improves floor panel transparency, scratch resistance, relief depth, and noise without UV curing.

A hollow veneer log uses MUF resin and cylindrical hot pressing to cut weight, improve bonding strength, and reduce warpage.

Fine lignocellulosic dust and thermoplastic powder are hot-pressed without added water to cut drying energy, swelling, and composite density.

By cutting logs into consistent lengths, grading sticks, and finger-jointing laminations, this process reduces waste and upgrades lower-value timber.

Targeted densification of the bamboo inner layer boosts strength and density while reducing energy use and volume loss during compression.

Uniform log segmentation, stick grading, and robotic lamination turn lower-valued logs into stronger laminated beams with less waste.

A two-stage pressing process secures wood layer positioning quickly, then builds durable bonds on PVC-rich composite cores with hot-melt polyurethane adhesive.

Applying additive before binder lets it stay at the veneer surface and penetrate during pressing, improving board properties with a simpler build.

Densified, lignin-modified wood veneers wrap around an axis to form strong hollow structures while reducing reliance on plastic, metal, and concrete.

An elastic polymer sheet distributes pressing force to preserve veneer embossing and reduce hazy portions from incomplete curing.

Dynamic planing head motion machines second recesses along the feed direction, eliminating production stops required by static shaft positioning.

Intentional peeling checks generated by a roller nose bar create internal channels that facilitate rapid water removal during high-pressure compressive drying.

Embossing a groove before milling prevents cracking of thin wooden layers and eliminates the need for protective coatings on exposed substrates.

Infrared heating softens the core material while lubrication reduces friction, enabling deep curved edge compression without cracking the decorative layer.

Sugar beet pulp extends aldehyde resin adhesives while stabilizing viscosity and retaining moisture in lignocellulosic panels.

Casting heating elements inside large platens eliminates precise bore holes and prevents overheating, reducing replacement costs.

A multi-layer thermal insulation system uses moving and static air layers to reduce heat transfer from heater blocks.

A horizontal multistage drying apparatus conveys veneer sheets in a standing state through sequential heating and transpiration stages.

Catalyzed polyurethane adhesives maintain elasticity during slicing while curing under heat to resolve toxicity and working life contradictions.
