Droplet Deposition

Droplet Deposition is a unique welding system developed in conjunction with Philips.  

The system produces and deposits accurate droplets of molten copper which may be used as a solder free method of terminating wires to other materials.

Primarily lamp manufacture

• Higher quality joints

• Lead and Flux free joining process

• Reduced process time compared to traditional technologies

• Faster production rates RS232/485 interface

• Full integration into turnkey systems possible

Droplets can be pre-programmed, typically between 0.7 and 2.5 mm in diameter, to cover a wide range of joining applications. The DDE offers new possibilities in joining applications and is an excellent alternative to certain hot bar soldering applications. DDE is a contactless process offering an ideal alternative to resistance welding for the joining of conductive materials such as copper wire to terminals.

Droplet Deposition Welding Systems

Abbreviated DDE, the machine is a joint development between MacGregor Welding Systems and Philips Centre for Manufacturing and Technology based in Eindhoven.

A revolutionary new method for precision metal joining, the DDE is a highly advanced welding system.

Capable of producing two welds per second, the process works by creating a precisely controlled molten droplet from a wire feed. Fully automated, the molten droplet can be accurately projected to almost any joint. A wide range of feed wires can be utilised including copper, molybdenum, nickel, aluminium and tungsten.
