4FT Fully Automatic Putty Spreading Line
4FT Fully Automatic Putty Spreading Line
The 4FT Fully Automatic Putty Spreading Line is an advanced surface treatment solution designed for plywood and wood-based panel production. It automatically applies putty to fill surface defects such as holes, cracks, and depressions, ensuring a smooth and uniform panel surface before sanding, laminating, or finishing.
This production line integrates conveying, putty feeding, coating, leveling, and stacking processes into a continuous automated workflow, significantly improving efficiency while reducing labor costs. It is widely used in modern plywood factories aiming for high-quality panel finishing and mass production.
