Contract Manufacturing

As a leader in Contract Manufacturing, ASI manufactures three product lines under license for other Original Equipment Manufacturers.  Through these manufacturing agreements, the OEM’s provide their intellectual property to ASI, for built-to-spec requirements and quality control.  This is a value-added advantage for these OEMs since ASI provides all the labor, tooling, and other value-added assets to manufacture these product lines eliminating the need to invest in additional manufacturing infrastructure or use up valuable capacity in their own shops.  ASI incorporates a cellular, Lean, Six-Sigma approach to the manufacturing of these products.  We are relentless in our pursuit of incorporating cost-saving methodologies in the manufacturing process.

Product Manufactured: Kitchen a la cart™   

OEM:  Edible Education-USA


Application: #1 portable teaching kitchen in the world! Teachers and administrators love Kitchen a la cart™ because it is an exciting tool that they can use to educate students in a non-traditional manner. The cart and curriculum provide a means to use culinary arts to teach core education concepts. For example, the cart can be used to help students learn/understand the concept of measurements, fractions, and percentages!  However, the main goal of the program is to teach students how to cook and eat healthy meals.

ASI has become a leader in remanufacturing of OEM equipment.  As the result of lead times that don’t meet the needs of the customer, for replacements, our DoD customers often-times contracted us to remanufacture a current system.  As a result, ASI has become a leader in remanufacturing shell and tube heat exchangers and cooling skid equipment.  Some of our recent projects include:

Product Remanufactured:  Main Condenser USS WASP

OEM:  Delaval Condenser Group now DC Fabricators, Inc.


Application: The main condenser is a heat exchanger designed to condense steam exhausted from propulsion turbines and recover the resulting condensate for use in the boiler feedwater system. The condensing process is accomplished by the transfer of heat from exhausting steam to cool seawater flowing through 6,537 copper-nickel alloy tubes. The tubes run the length of the main condenser shell and are supported at both ends by the tube sheets which are drilled with holes into which the tubes are secured. Tube support plates are spaced at intervals within the shell to support the tubes and prevent vibration. The tube sheet and tube support plates are welded to the main condenser shell.

Product Remanufactured:  Radar, Sonar, Spy and C&D cooling skids

OEM:  Lockheed Martin Corporation

Application:  Provide cooling water to the Radar, Sonar, Spy and C&D systems on a Ticonderoga-Class Missile Cruiser warships.
