Explosive hydro-forming has been an accepted metal-forming technique for nearly decades. It’s used in a wide variety of applications in the automotive, aerospace, and maritime industries. The Hermetic Solutions Group has extensive experience in using this technique to form a range of metals. Typical forming projects yield very close tolerances and very high degrees of repeatability.
The explosive hydro-forming process can offer significant cost savings on short-run parts because, often, it only requires a one-sided tooling die. During the explosive hydro-forming process, the water slug applies force evenly over the surface of the work piece, as it forms into the cavity of the forming die.
Let's discuss your application to determine how it might benefit from materials created by explosive hydro-forming.
Explosive Forming Benefits
Explosive hydro-forming can also efficiently form larger parts. Since the power generation comes from an explosive charge, you don’t need larger machinery to form large parts, you simply apply a larger charge.
Explosive hydro-forming delivers many benefits. It generally involves lower tooling costs and uses stamping type applications which only require a one-sided tooling die. Explosive energy can be transmitted differently across the part, in order to concentrate force onto specific forming features. It has a large size capability and is suited to difficult configurations.
Explosively-formed parts can range up to 6 feet and have very few limitations. Explosive-forming can simulate many aspects of all other conventional forming methods, without their respective limitations.
