Lock forming machines
Buildings of various configurations and uses are usually equipped with HVAC (heating, ventilation and air conditioning) systems that help supply fresh air into rooms, remove exhaust air, and heat and cool air when necessary. Depending on the type of design, duct systems can be round or square. Round ventilation systems can be made with special spiral duct machines or using plate bending machines, lock closing equipment, elbow making machines and swaging machines.
Rectangular HVAC systems can be made with special lock forming equipment to produce duct system locks, a flange folding machine to bend duct samples to square, a lock seaming tool to close HVAC locks and to connect the TDC flange to the square duct.More..
