The HTA Group serves an elite portfolio of tier 1 aerospace clients including Boeing, Lockheed Martin, Northrup Grumman Corporation, Goodrich Actuation Systems (UK), Collins Aerospace Landing Systems, BAE Systems and Space X .
For over 15 years, the HTA Group has provided accredited heat treatment processing services to the global aerospace industry. Prime contractors, OEM’s and supply chain businesses look to HTA on a regular basis to process a huge variety of airplane and aerospace components, both commercial and military. HTA is NADCAP and AS9100 certified for multiple processes, meaning that these customers are assured of consistent quality outcomes. The HTA Group has three locations in Australia, and one on the West Coast of the United States.
“We demand high quality, precision solutions due to the stringent requirements of the aerospace applications that we work with. Seco/Warwick meets and exceeds these demands, hence we placed our seventh order for their technology because of their experience with these clients. This expertise helps us to meet our promises,” says Norm Tucker, Director, HTA Group.

First order in 2007

The HTA Group bought the first Seco/Warwick furnace in 2007. Since then, there have been four furnaces in the Brisbane location, and two in the USA plant. This order is the 3rd vacuum furnace to be used for vacuum brazing aluminium parts.
The system has been designed with six temperature control zones in order to meet the tight temperature requirements of +/-3 °C as specified by the AMS2750F pyrometry specification. The powerful high vacuum system will be equipped with a large diffusion pump. The furnace can accommodate loads up to 800x800x1,600 mm (WxHxD). The furnace will be equipped with an external gas cooling system which will accelerate the process, and improve the part quality after brazing.
The VAB furnace allows the brazing of aluminium parts for applications where the use of brazing flux is not permitted due to corrosion. This process is typically used for the most critical applications.
“Seco/Warwick has for years been providing high-end solutions on the most demanding applications for the aerospace industry all over the world. We are experienced at meeting all the specifications and continuously exceed them to secure our clients with the best heat treatment solution available today and in the years to come,” says Maciej Korecki, VP, Vacuum Business Segment, Seco/Warwick Group.
