Domestic Manufacturing Facility
John Hassall's manufacturing operations are centered around a modern 100,000 square foot facility located in Westbury, New York. John Hassall has earned a worldwide reputation for outstanding quality, achieved through ongoing investments in its people, as well as in the latest manufacturing technology.
Customer Service
Every John Hassall customer is supported by a team of talented hands on professionals, including an account executive, design engineers, manufacturing and quality assurance specialists. This multi-disciplinary team understands and anticipates the inherent complexities of each assignment. Drawing upon extensive experience and know-how, they work directly with customers to determine the most cost effective solution, often making product improvement and cost saving suggestions.
Computer Aided Design
John Hassall typically works from customer-supplied prints. We are also capable of providing complete product design solutions utilizing the latest state-of-the-art CAD/CAM systems. All engineering and technical support services are available through the Internet.
Cold Forming
Our manufacturing facility features hundreds of cold forming machines, including open and solid headers, as well as multi-station parts formers. In-house tooling allows for exceptionally fast turnaround for prototyping and sustained back up for production runs. Working with over 95 metal alloys, we can produce specialty parts in lengths of up to 9" and shank diameters from up to 0.406".
Hot Forging
Hassall performs hot forgng on 66 and 88 ton presses equipped with numerically controlled induction heaters that produce for the most part high strength aircraft engine bolts. These bolts are made of such hi-temp alloys as Inconel 718, Waspaloy, MP 159, materials that need to be heated to 2,000°F to allow for their deformation during the forging process. It also requires a great deal of experience and metallurgical lab support to assure part integrity and conformance to customer specifications throughout the process. With this capability, we can produce parts up to 4" in length with shank diameters of 0.500".
Screw Machining
Hassall also operates a limited number of Swiss type automatic
CNC bar fed lathes for the production of aircraft engine pins and bushings. Because of either low quantity or geometric configuration, some parts are not good candidates for cold heading or hot forging. Being able to use all three primary sources of manufacturing gives Hassall greater flexibility and the opportunity to provide more service to its customers.
Tooling
John Hassall’s ability to manufacture precision parts using cold forming technology is directly related to our in-house design and tool making capability. Since the early 60’s, John Hassall toolmakers were amongst the first to use and perfect the use of carbide in their heading tools, which allowed for the production of cold headed parts with close tolerances. For example, holding shank diameters to within 0.0007" is not uncommon.
Secondary Operations
John Hassall supports its cold forming and hot forging capabilities with a variety of secondary operations, such as hand fed
CNC chucking and automated bowl fed Swiss turning, trimming, automated and hand fed thread rolling on flat and tri-roll equipment, broaching, automated end and cross hole drilling, tapping, milling, centerless grinding and electro-chemical grinding.
NADCAP Certified Heat Treating
Hassall's state-of-the-art heat-treating facility was specifically designed for specialized requirements most commonly called for in military and aerospace applications. John Hassall has vacuum and atmospheric furnace for hardening and tempering, solution & precipitation hardening and annealing; automated induction heaters for selective annealing and hardening; cold treat freeze capability to -120°F.
Complete Metallurgical Laboratory
Equipped to provide both destructive and non-destructive testing, as well as micro/macro evaluations of materials and parts, Hassall’s lab operates under the surveillance of Pratt & Whitney’s Material Control Laboratory, is registered and approved by Honeywell Aircraft Engines and MTU Aero Engines and conforms to GE Aircraft Engines S-400 guidelines. Testing conducted within this lab includes: X-ray spectrometry, metallography, shear/tensile/yield, hardness and stress rupture (creep).
Statistical Process Control (SPC)
To ensure adherence to Total Quality Management (TQM), Hassall utilizes Statistical Process Control (SPC) techniques involving networked data collection workstations. Here, we collect historical information on critical product/process variables and attributes. Many of our manufacturing systems are also equipped with computerized process controllers for fail-safe operation.
100% Traceability
All products manufactured by John Hassall are 100% traceable as a result of the strict batch control systems. All documentation procedures are developed in accordance with customer guidelines. A complete library of product samples and accompanying paperwork is maintained and readily available for customer inspection.
