About Woolf Aircraft Products, Inc.

Items Currently Manufactured
All tube assemblies used on tracked military vehicles, medium to heavy trucks, turbine engines, aircraft, diesel engines, automatic transmissions, tractors, automotive and specialized vehicles.

Manufacturing Range
We fabricate almost any tube - large or small - we specialize between up to 7 ", and go all the way up to 8" diameter - 1 piece through 40,000 piece lot size.

Operations Performed
Tube bending, welding, flaring, flanging, expanding, swedging, forming, flattening, sheet metal, punching, stamping, machining, milling, turning, surface grinding, shearing, boring, hydroforming pre-bending, tool and die, brazing, Zy-glo and more. We also use the many outside services available in the greater Detroit area.

Experience
Located for 45 years in Wayne, we relocated in 1986 to our 10 acre site in Romulus,

Ability to Perform Contracts
Contracts held range from $100.00 through $500,000.00 each. The average number of contracts in production at any time is over 1000.

Manufacturing Plant
Our Romulus facility has 94,000 square feet on 10 acres near I-94 and I-275. It is designed for future expansion and growth. We are minutes from Detroit Metropolitan Airport and the major trucking terminals.

Inventory
Over a thousand different types and sizes of stainless steel, inconel, carbon steel, aluminum, brass, copper and titanium are stocked to Military, AMS, and ASTM standards. We also inventory many types of fittings used on aircraft and military vehicles including flanges, screw machine parts, hydraulic fittings and stampings. Our inventory is one of the most complete in our industry.

Skilled Work Force
Many of our 100 employees have been with us for over 20 years. We have trained some to become tool and die makers, certified welders, experienced tube benders, and machine operators. Our training program is approved by the Veterans Administration, and we use the local school and colleges.

Convenient Location and Delivery
Understanding that availability of raw materials is the most important factor, our facility is conveniently located near major tubing mills and distributors. We are only minutes from freight lines, air carriers and UPS for next day delivery. This enables us to receive raw materials and ensure that shipments of finished products are received when needed by our customers. Here at Woolf Aircraft, Inc., we are experts at: tube bending, welding, flaring, flanging, expanding, swedging, forming, flattening, sheet metal, punching, stamping, machining, milling, turning, surface grinding, shearing, boring, hydroforming pre-bending, tool and die, brazing, Zy-glo, and more.

Woolf Plant Tour

Assembly Area - Main Office Hallway
Assembly Area - Main Office Hallway

Assembly Area - Main Office Hallway Here you can see pictures and a display along the hallway to view as we get your tour guide. In the office we quote the prices for parts and take orders. We then buy materials and schedule production as well as prepare shippers.

Tube Rack
Tube Rack

Tube Rack - We begin by purchasing straight tubing in 12' - 24' lengths. In these racks and on the receiving floor is the tubing from which we will make our assemblies. We stock 1,200 sizes and types of tubing. Some are not available anywhere except here.

Cutting Room
Cutting Room

Cutting Room - We cut the tubing to length with cut off saws or horizontal band saws. Two automatic deburring machines are available to remove burrs. We also trim some tubes to final lengths after bending.

#6 Pines
#6 Pines

#6 Pines - After the tube is cut it's bent to shape. Our largest #6 Pines bends up to 8" diameter tubing or solid bars up to 4 ". It's one of only 50 ever built. Most are in the large aerospace companies.

#4 Pines
#4 Pines

#4 Pines - We have seven 4" benders bending up to 6" tubing. One bends clockwise and the other hand counter-clockwise so we can fit the bends close together. We have two of only 70 matched sets of these machines in the world.

Big Bending
Big Bending

Big Bending - We have eighteen 2" benders - Our most common bends are formed here with bending tools. Think of it like bending around your knee with your knee being the bend die. Your first hand is similar to the bend clamps and the follow up bar is like your second hand holding it against your knee.

Degreasing
Degreasing

Degreasing - We wash the heavy oil and grease off the parts. The first tank removes about 90% of the oils & dirt. For final shipping we use the Ultrasonic center tank. It uses sound waves underwater to vibrate the part. This causes the dirt and oil to move away from the surface allowing the soap to soak up the oil. Parts are then rinsed off in clear water as needed.

Press and End Forming
Press and End Forming

Press and End Forming - We form the ends by adding beads, flares, flanges or expansions. The beads allow hoses to be installed with a clamp and not come off. The ends can be made in many shapes and sizes.

Fitting Department
Fitting Department

Fitting Department - This area takes the bent tube and cuts it to fit closely to a second tube. These parts are then welded together.

Rotary Tube End Forming
Rotary Tube End Forming

Rotary Tube End Forming -These machines also install beads, flanges and flares to the tubes similar to the Vaills, except the process is roll forming. Size goes up to 6 inches.

Small Bending
Small Bending

Small Bending - It is easy to follow the fabrication process since most operations including bending and flaring are done here in smaller sizes, up to 5/8 ".

Machining & CNC Machining
Machining & CNC Machining

Machining & CNC Machining - This area is used for CNC & heavy machining

Inspection
Inspection

Inspection - We use first piece, in process and final inspection methods to insure our parts conform to requirements. Here the diameter of a set up piece is measured and then analyzed using Statistical Process Controls (SPC).

Toolroom
Toolroom

Toolroom - We build our own fixtures and machine complex parts. It takes about 4 years to become a journeyman. We have provided local college classes for employees to learn the math necessary for this and other areas.

Brazing
Brazing

Brazing - Brass or silver solder is melted when using a torch to heat the metal parts. Their heat melts the solder, not the flame directly. A flux is used to keep the joint clean. It is different from welding because the parent metal is only heated, not melted together.

Welding
Welding

Welding - Do not look directly at weld - It is bright like the sun! We weld as thin as 4 thickness of newspaper, in steel, stainless, aluminum, inconel and titanium. Woolf provides local college classes to employees in order to learn Tungsten Inert Gas (TIG) welding and uses the latest Miller welding machines.

Zyglo
Zyglo

Zyglo - Here we check welds or material for cracks and other defects. A dye soaks into the crack. A developer then draws that dye out to expose the defect.

Inventory
Inventory

Inventory - Finished and in process parts are stored here waiting to be released. Most customers want only a few parts at a time. This area is for expansion and will become future office space as we hope to build for the future.

Shipping
Shipping

Shipping - Many of our finished parts travel thousands of miles shaking in the back of a semi-truck. Some might be used on airplanes, large trucks or for race cars. We count, protect and give them a final look for their journey.
