Hartco is the one legitimate company of only engaged in aerospace flareless tube fitting swage technology in China. We are a set design, research and development, manufacturing, sales in the integration of high-tech enterprises.
Hartco committed to research and develop flareless tube fitting swage technology for aircraft and aircraft engine. We processing and experiment for aircraft hydraulic, fuel, lubricating, gas, environmental control tubing.
Hartco independently research and developed "Flareless tube fitting elastomeric swaging machine" and "Flareless tube fitting roller swaging machine", there is advanced technology, leading in the similar equipment.
Hartco independent research and developed "Model 7777A flareless tube fitting elastomeric swaging machine " is the only one fully automatic machine of double head working at the same time. It used polyurethane tube expander and high strength mandrel, the latter′s material is also used on centrifuge spindle of nuclear industry. By insert expander assembly to tube, pull the mandrel of expander assembly, the polyurethane expander deformation expansion, then press tube wall materials into the grooves of sleeve or union.
" Model NXTRS Flareless tube fitting roller swaging machine " is latest next generation roller swaging machine, is improved on the original Sierracin/Harrison old type roller swaging machine. By putting a expander inserted into the tube, mandrel rotation and forward drive make the three roller on expander to contact tube inwall, press tube wall materials into grooves of sleeve or union. It not only can swage Sierracin/Harrison flereless fitting to tube, but also can be in accordance with SAE, military specifications and other kinds of tube fittings used in roller swage technology, greatly expanding the application fields of this technique.
Hartco tried to looking for met the need of the aerospace tubing processing and testing advanced equipment, introduction, localization of improvement, including: "Tube circular saw cutting machine", "Tube vertical band saw cutting machine", "Tube end finish machine", "Tube bending fatigue strength test bed", "Tube pulse strength test bed", and other important equipment, formed a complete set of aircraft tubing processing, testing production line, service in the domestic aerospace manufacturing and MRO industry. So that, the user of domestic aerospace industry to using high performance equipment same as Euro or United States. At the same time, save a lot of money, enjoy a more efficient service.
Hartco introduction of technology from the United States the "Tube end finish machine". Using the tube end finish machines, the ends can be prepared with a bead or flare, or simply deburred and squared. Each machine is capable of performing all of these functions -- a change of tooling is all that is required to switch from one function to another...It is the first one of one work station to achieve a variety of processing in domestic tube end finish machine. In addition, the machine clamp in front side of machine, working head located at the top of machine, ensure that the opening and no interference, to ensure the tube end reprocessing of bended complex shaped tube.
Hartco independent research and development of "Tube precision circular saw cutting machine" is a very distinctive device, equipped longitudinal cutting saw, using the thin clamp or cellular work platform, insure cutting of bended complex shaped tube.
Hartco increasing participation in each military and civilian project, provide advanced technology and equipment for domestic aircraft manufacturing industry, improve the level of technology and the use reliability of domestic aircraft.
