What Is a Finger Joint Press Machine? Working, Features & Uses – Complete Guide by Sundaram Corporation
The woodworking and timber industry has evolved significantly over the years, and modern manufacturing demands stronger, longer, and more efficient wooden components. One of the most remarkable innovations that supports this growing need is the Finger Joint Press Machine. This machine not only enhances wood strength but also helps industries reduce waste and improve productivity.
At Sundaram Corporation, we specialize in providing high-performance finger joint press machines designed to deliver precision, durability, and maximum output for woodworking units. This blog explains everything you need to know about what a finger joint press machine is, how it works, its key features, and where it is used.
- What Is a Finger Joint Press Machine?
A Finger Joint Press Machine is a specialized woodworking machine used to join short pieces of wood to create longer, stronger, and more stable wooden boards. The joint formed resembles interlocking “fingers,” which is how it gets its name.
These interlocking fingers provide:
- Higher strength than regular butt joints
- Greater load distribution
- Minimal material wastage
- Excellent bonding for long timber production
The machine is widely used in furniture manufacturing, panel production, joinery applications, and timber processing industries.
- How Does a Finger Joint Press Machine Work?
The working of a finger joint press machine involves multiple stages, each designed for precision wood joining. Here’s a simplified breakdown of the process:
Step 1: Wood Preparation
Wooden blocks or small timber pieces are prepared by trimming and aligning them to the required size. The ends must be flat and clean before processing.
Step 2: Finger Cutting (Profile Creation)
The ends of the wooden pieces are cut into finger-like profiles using a finger joint cutter.
These are usually:
- V-shaped
- Zig-zag shaped
- Interlocking rectangular cuts
This profile is essential for a strong joint.
Step 3: Glue Application
A high-quality wood adhesive is applied precisely to the finger profiles. Proper glue application ensures:
- Maximum bonding strength
- Long-lasting joints
- Resistance to stress and tension
Step 4: Pressing & Jointing
The wood pieces are placed inside the Finger Joint Press Machine, where powerful hydraulic or pneumatic pressure pushes them together. The interlocking fingers lock firmly, creating a seamless and strong connection.
Step 5: Curing & Finishing
Once pressed, the joint requires a short curing time. After drying:
- The board becomes ready for cutting
- Surface finishing can be done
- Panels can be further processed for furniture or construction
