The Veneer Defect Patcher is a specialized machine designed for repairing face veneers in the plywood production process. As large-diameter logs become increasingly scarce, patching technology is essential for maximizing usable veneer from smaller logs. By removing scars, cracks, and holes, this machine ensures higher veneer quality and efficiency in panel manufacturing.
With advanced pneumatic and hydraulic systems, the veneer patching machine performs defect punching and patching in one process, significantly reducing manual labor, improving repair speed, and delivering consistent high-quality results.
The Veneer Patcher uses pneumatic cylinders and precision molds to remove defects such as knots, cracks, or holes, and replaces them with patches in standard shapes like butterfly, oval, or boat patches. The butterfly patch is the most efficient, offering durability, stability, and up to 25% savings in patching material.
Unlike traditional methods that require two separate machines, the Veneer Defect Patcher integrates defect punching and patch cutting in one unit, using up to six molds simultaneously for efficient operation.
| Model | JDMD7180-MK | JDMD7181-MK |
|---|---|---|
| Maximum working depth | 780mm | 780mm |
| Mending veneer thickness | 1.0–3.0mm | 1.0–3.0mm |
| Mending veneer size | 40×60mm | 40×100mm |
| Mending speed | 3–5s/time | 3–5s/time |
| Weight | 1300kgs | 1500kgs |
| Power | 4.25kW | 4.25kW |
Integrated Functions – A single device performs both defect punching and patch cutting, reducing equipment investment and maintenance.
Pneumatic Booster Cylinder – Greatly reduces manual labor and simplifies operation.
Customizable Mold Sizes – Male and female molds can be customized (40×60mm, 60×100mm, 90×150mm, etc.) to meet specific repair needs.
Stable & Durable Frame – Made from welded steel profiles for long-term performance.
High-Precision Molds – Ensures accurate cutting, consistent patch size, and reliable durability.
Multi-Size Repair – Capable of fixing veneer scars and holes of different shapes and dimensions.
Handles veneer sheets from 0.2mm to 6mm, suitable for both softwoods and hardwoods. Achieves rapid defect removal and patching with cycle times as fast as 2 seconds per patch, which is 6–10 times faster than manual repair.
Equipped with a red crosshair laser module for pinpoint defect alignment, ensuring precision patching even on irregular veneer surfaces.
Offers interchangeable molds (butterfly, oval, rectangular, boat shape) to adapt to different defect shapes and plywood manufacturing requirements.
Innovative punching and embedding design eliminates the need for glue or tape, reducing material costs and environmental impact.
High-quality steel molds and robust pneumatic systems ensure long service life. For example, mold lifespan exceeds 6 months for 4mm-thick veneer and up to 1.5 years for thinner sheets.
The Veneer Defect Patcher is ideal for plywood factories, veneer plants, and furniture manufacturers that require high-quality face veneer. It is widely used in industries where veneer surface quality directly affects plywood strength and appearance.
Our machines have been successfully exported to Asia, Europe, and South America, gaining a strong reputation for reliability and efficiency in veneer repair.
