Thermal Drilling System, Formdrill

Unimex Formdrill India Pvt Ltd offers a Thermal Drilling System, Formdrill. Thermal drilling is a process that uses friction to produce bushings in metal tubing and flat stock. Friction is generated from the combined rotational and downward forces using a special thermal drilling tool, Formdrill. The friction heats up the metal and softens it, allowing the tool to create a bushing from the displaced material. This bushing is roughly 2 to 3 times the original metal thickness in length. These bushings are ideal for threaded applications, as the number and strength of threads is significantly increased. It is a cost-saving alternative to welded nuts, bosses or threaded inserts. The bushing can also be used as a through hole for welded, soldered or brazed connections or for a load-bearing surface. The thermal drilling system can be used in most ferrous and non-ferrous metals including mild steel, stainless steel, copper, aluminium, brass, and bronze, with material thickness up to 12.0 mm. Standard drills are available in any size up to 25.4 mm diameter. No special equipment is required, a standard drill press, milling machine or CNC systems are suitable.
