A new snap-together joinery system for cabinets works so well that the boxes can be assembled and stacked without human intervention.

The Swedish company Valinge demonstrated the Threspine click furniture technology at their booth at the International Woodworking Fair in Atlanta. 

Based on the same 5G technology regarded as a standard for installing flooring, Threespine is a patented innovation that enables furniture and cabinet parts to be assembled om seconds without tools. Parts snap together solidly, creating perfect alignment and a robust joint, spreading the load all along the connection surface.

In a live demonstration at the Valinge booth a robot arm would lift parts into place, then apply pressure to snap-lock the joinery. Once the box was fully assembled, the same robot would pick up the completed box and lift it to a stack on the side before starting to make a new box. No adhesive is used, and no human assembler is needed.

Valinge says this joinery opens up a variety of new possibilities. There are no visible fasteners or connecters to detract from the appearance of the cabinet. The system offers the possibility of working with thinner components, combining different materials in new ways.

Threespine is optimized for high-volume production with no gluing or screwing required. By using assembly robotics, you can minimize assembly time and maximize output.
