Founded in 1947, GTC is a world class, privately held U.S. firm that, over the years, has grown from a small job shop to a full-service contract manufacturing business supporting a large number of the aerospace, defense, power generation, and commercial industries' needs for specialty machines, equipment, and components.
GTC is not a typical job shop, as demonstrated by the following unique characteristics.
- In business since 1947
- 275,000 square foot complex with 40 ton overhead crane, 28 clearance under-hook
- State-of-the-art precision machining, fabricating, assembly, electrical and testing capabilities
- ISO 9001: 2000 with AS9100: 2001 Rev B
- NADCAP Certified for Welding and NDT (Level 3)
- Over 60% of production equipment has been replaced or upgraded in the past 5 years, capped off by a $5 million expansion plan.
- Technology investments have been made in the form of new CNC host programming systems, DNC network, and company-wide LAN with integrated management system of sales, production and finance.
In the past few years, a transition has been made from manufacturing of development hardware or one-of-a-kind equipment, to a 50-50 mix of development and production work. The DDG 51 Navy generator sets manufactured for Rolls-Royce provide a good example of production work that encompasses all phases of our program management, manufacturing, assembly, and test capabilities.
GTC has managed the assembly integration of the AG9140 gas turbine powered generator set (3.0 MW), since 1987, for the U.S. Navy (DDG/Arleigh Burke class destroyers), without missing a single delivery. GTC procures hundreds of components, fabricates hundreds more, assembles complete systems including all electrical and piping, and performs final acceptance testing.
General Tool has demonstrated the ability to deliver MIL-spec turbine packages on time, with documented cost savings shared with the customer. The U.S. Navy and Rolls-Royce Gas Turbine have formally recognized General Tools consistent, quality performance.
GTC Manufacturing and Tooling Engineers provide solutions to a broad range of very specific design problems and requirements. With our considerable experience in manufacturing techniques and application, we are consistently the ideal project partners for our customers. When appropriate, concurrent engineering allows us to contribute our ideas for improvement in manufacturing design- often a key ingredient to realizing superior results.
Our programming system can be integrated with customers CAD/CAM platforms using Solid Works, CATIA, Unigraphics, AutoCAD, Surfcam, and others using IGES Translators. Direct communications are provided as needed to fulfill customer requirements.
GTC is a provider of engineering services, knowledgeable, innovative, and technically competent, specializing in computer modeling, engineering analysis, product design and advanced manufacturing techniques. Our excellent technical knowledge and project management skills have enabled us to design aerospace systems and components, including the support equipment and tooling required for manufacturing and assembly. We have the in-house technical and analytical expertise needed to support the design, development, and sustaining engineering of any product on the market today.

General Tool Company's machine capability is one of the largest and best equipped in the nation with a number of advanced machining centers, some of which are unique in this field for size, power, and productivity. In addition to standard turning, milling, boring, and grinding machines, the company provides dozens of state-of-the-art four and five axis CNC and DNC high horsepower, high production machining centers.
The fabrication department is fully equipped to provide world class welding/ fabricating services, including Friction Stir Welding, 350 ton press break, ½" x 12' shear, and high definition plasma cutting capability, with 40 ton lift capacity and 28 of vertical clearance. The department is directed by a Certified Welding Engineer and routinely applies the most advanced MIG and TIG welding processes on almost every type of alloy, to the demanding specifications of AWS D1.1, ASME Section IX, MIL-STD-248D, and MIL-STD 1595A.
The assembly department offers three bays, each 200' x 50' with a maximum lift capacity of 40 tons and 31' of vertical clearance. Designed for flexibility and security, each bay may be separated and subdivided so programs can be conducted privately and exclude unauthorized personnel. In addition, private office suites adjoining the assembly department are provided for customer representatives who are directing and monitoring programs in process. The assembly area is climate controlled and equipped with power sources to operate the most advanced system, including programmable logic control, robotic, electrical, hydraulic, and pneumatic systems. Adjacent to the assembly facility, an indoor turbine package test cell is available for performance testing.
GTC's Plant 2 is an office/manufacturing complex that offers an attractive site for the cleaning and shipping of the parts. Over 32,000-sq. ft. of manufacturing space and 7,500sq ft of office space (including the climate controlled quality control department) can be dedicated to a program. The production bay is equipped with two (2) 10-ton cranes each with two (2) 5-ton hoists and 19.7 ft. under hook clearance. The plant is equipped with a paint facility, a certified class 1000-cleanroom facility, and has nine shipping and receiving docks distributed about its perimeter.
General Tool Company's 1000 Class Clean Room Facility consists of a three room layout to facilitate the final cleaning, drying and assembly of parts connected to these rooms is a gown room, a staging area (clean area, HEPA filter airflow), and an air-lock area.
