TRC 1500 – Timber Repair & Cosmetic Machine
Technical Description • System Overview • Process Workflow

System Overview
The Wintersteiger TRC 1500 is a fully automated industrial system designed to detect, repair defects in wooden boards. It combines advanced 3D scanning, high-pressure thermoplastic injection technology to deliver consistent, high-quality repairs at production speed. Defects are repaired with thermoplastic filling material using injection and application units. No filling material is wasted thanks to the precise calculation of the filling quantity and precision injection.
the edges can also be filled.
