(Click to enlarge image) Ogden Group manufactures the DRS 300 Wood Repair system that is designed to fill and repair knots and cracks in wood flooring. As the use of reclaimed wood and consumer demand for character grade flooring has increased, manufacturers have struggled with finding an easy way to finish defects. With the DSR 300, the operator places the wood parts under the injection head, and using laser cross hairs, isolates the defect location. The hot patch solution is then injected with pressure into the defect. An internal cooling system quickly solidifies the hot patch solution. The patch can later be stained and finished. The DRS 300 Wood Repair System can come with one injection head or multiple heads for different colors.
