This high speed machine is ideal for all types of work from complex tube designs to large volume orders, such as the new King Shaka airport – all of the stainless steel balustrade and stanchions for this project were cut on the laser tube machine.
The plasma is hot enough to melt the metal being cut and moves fast enough to blow molten metal away from the cut. Oxy fuel cutting is used for materials over 32mm and in this process pure oxygen is used to increase the flame temperature to allow localised melting (cutting) of the material, at 3,500 ͦC
These machines have a bed width of 3 metres and are capable of bending up to 4mm steel over this entire length. These press brakes are also equipped with tooling that allows the machines to bend to within a 0.3 degree tolerance.

TIG welding is a process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is applied.
TIG welding is a slower and more specialised process than MIG welding and is best used for the welding of complex parts that require high quality finishes. It is also mainly used for the welding of stainless steel and aluminium components.
The robot welder uses the MIG welding process and this generates a consistent, high quality weld and is ideal for the fabrication of high volume parts. The robotic system consist of three work stations, each of which can accommodate several parts in a jig and while one workstation is being welded, the other work stations can be loaded / offloaded.
SPOT welding can be used for material from 0.5 to 3mm in thickness. The contacting metal surfaces are joined together by the heat obtained from the resistance to electric current – the process is applied using two shaped copper alloy electrodes that concentrate a welding current into a small “spot” and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld.
Powder Coating is the most common process where a dry powder is applied to a metal surface electrostatically and is then cured under heat to allow the powder to flow and form a skin. Electroplating is another widely used process that essentially uses an electric current to apply a thin layer of protective metal to a surface, such as Zinc. Zinc is anodic to steel and it will corrode before the steel does, sacrificing itself for the benefit of the steel.
The team often works closely with the design teams of larger customers to assist with research and development, design issues and product realisation. The design team will actively review and analyse customer designs and specifications to ensure best manufacturing practice is applied and cost efficiencies are realised.
For smaller customers, the team will complete the design working from verbal instructions, a sketch or a sample part.
