TRC Repair – fully automated repair and patching technology for wood surfaces

Fill and patch cracks, knots, and defects automatically – in line and at high speed.

TRC Repair is the fully automated repair and patching solution from WINTERSTEIGER for visible wood surfaces with the highest quality standards. The TRC process combines precise dosing technology with innovative fillers. Smaller defects such as cracks or damaged areas are filled with millimeter accuracy, while larger inclusions such as knots or holes are patched for homogeneous, high-quality surfaces and optimal downstream processing.

What is TRC Repair?

TRC Repair is the fully automated repair process from WINTERSTEIGER for wood surfaces. The system differentiates here between two core processes, both of which are fully automatic, in line, and run at production speed without any manual finishing being required.

 

Filling

Small defects such as cracks, scratches, or surface damage are sealed with millimeter accuracy using precisely dosed fillers.

Patching

Larger defects, such as knots, holes, or openings are fully patched to ensure seamless repairs with virtually undetectable transitions.

TRC Repair

TRC Repair combines precise dosing technology with automated patching for wood surfaces that stand up to the highest visual and technical processing requirements.

Real wood inserts directly from your own material

Repair with patches from your own wood strips

The TRC Woodpatch technology creates real wood inserts directly from your own wood strips and presses them in precisely the same direction as the wood fibers. This produces a high-quality and robust repair, usually in just one pass.

Stabilizing of defects through high-pressure injection

Continuous knot fixing

The TRC Knot-fix system fixes both loose and cracked knots automatically through high-pressure injection. The material fully penetrates the defect to ensure long-term stability even after the wood has been split into thin lamellas. The technology works reliably with a wide range of material conditions.

 

Where is TRC Repair used?

TRC Repair systems are used wherever visible wood surfaces have to meet the highest quality requirements:

Flooring and boards

Defect repair in a running production line

Furniture fronts and panels

Millimeter-precision repair without visible transitions

Door panels

Defects around the edges of the component can also be repaired completely automatically

Solid wood products

Real wood insert for visually seamless integration
