MDI combines cutting-edge technology with good, old-fashioned craftsmanship to create products that surpass even the most stringent standards. Below you can find a list of the service that we off. For a full list of machines and details please download the PDF below.

Titanium Hot Forming

MDI is an approved supplier for the titanium hot form specification with Boeing, McDonnell Douglas, Bell/Textron, Northrop Grumman and Lockheed/Martin Marietta. With the addition of two hot presses, a Murdock 3′ x 5′ platten with side rams and a 2′ x 2′ Dake, a portable oven and a portable quartz heater, we have expanded our overall capabilities in the area of hot sizing, hot forming, and warm forming with the follow equipment:

Hot Brake Forming
Hot Hydroforming
Hot Hammer Forming
Hot Stretch Forming (Wrap)
Portable Electric Oven
Portable Quartz Heater
Titanium Alkaline Clean Line

Drop Hammer

MDI’s drop hammer capability includes in-house tooling capabilities.

MDI has two Ceco air drop hammers, the largest with a 48″ x 66″ bed size and a smaller hammer with a 36″ x 48″ bed. Although an older method of complex contour forming, drop hammers are still comparatively inexpensive and efficient alternative to some of today’s newer methodologies.

Plus the fact that MDI has the capability to build drop hammer tooling allows us to maintain total control in meeting your requirements.

Laser Cutting

MDI’s Laser/Punch Press supports forming operations and flat pattern work to reduce cost and cycle time.

MDI’s 1500 watt hybrid laser/punch press combines the contouring ability of a fixed laser beam with the high punching speed of a turret punch press. Its versatility enables the operator to cut unlimited sizes and shapes without the cost of special punches and dies. It allows for quick installation and start-up periods. The Laser has a long X-Axis overtravel. Lower setting time and higher productivity is the result of simplified tooling set up.

Punching and laser cutting programs are simplified by conversational type input CNC control with background editing capability.

Hydro Forming

MDI fabricates some of the most difficult close tolerance parts in the aviation industry.

MDI’s experience in Hydraulic/Rubber forming has allowed us to fabricate some of the most difficult close tolerance parts required for today’s commercial and military programs. Size capabilities for our equipment are 44″ x 64″ and 96″ x 12″ on the larger 400-ton press and 24″ x 42″ on the 200-ton press.

From smaller brackets and fittings to larger bulkheads and stringers, we can assist you in fulfilling your hydroform requirements.

Stretch Forming

MDI has equipment capable of Stretch forming both extruded material and sheet metal (skins).

Our skin presses allow for parts up to 6 ft. in width and 10 ft. in length with maximum thicknesses ranging to .125, depending upon material and size of parts. One of our presses has articulating jaws for more complex forming requirements and also comes with a bulldozer attachment.

One extrusion press is a Sheridan 12-20, which creates 12 tons of pull on the jaws with a 20-ton ram pushing against the tool itself. This double action press also has bulldozer and joggle attachments. Our other extrusion press is a Hufford A-5.
