How We Do It
Tooling can be engineered and produced rapidly while remaining inexpensive.
Over 60 hydraulic presses — 11 with cushion capabilities.
Press tonnage ranges from 50 to 1200 tons.
Largest press bed size 84” x 90”
Hydraulic presses minimize tooling and move slower to prevent parts from ripping
Deep drawn parts occur when depth of the drawn part exceeds its diameter and is an area of expertise for Duggan
Low Volume Stamping
Produce tooling that can withstand over 100,000 hits if needed
Applying lessons learned in the prototype phase to a higher volume speeds up time to market while saving customers money
We implement processes that mimic production process. Poka yoke features, check aids, serialization, and key feature gages
Blanks are set in the oven, heated to the required temperature, removed, and stamped. Parts cool then dog bone sections are cut out for testing to ensure consistency
Material is proprietary with a high Boron content treated in the oven up to 2000 degrees Fahrenheit
Yield strength before treating is 350 — 550 MPa and ultimate tensile is 500 to 700 MPa
Yield strength after stamping is 1100 MPa and ultimate tensile is 1500 MPa
Duggan can bend small brackets, large rails, and everything in between
Brake parts up to 14 feet with capabilities ranging up to 350 tons
Multiple brackets formed efficiently by bending 3-axis blanks with existing tooling
Quickly add secondary tabs and features
Customers benefit from no tooling cost and short turnaround times
