A UNIQUE DRAW PROCESS
FOR PRODUCING PARTS TO YOUR SPECIFICATIONS. HYDROFORMING IS A GREAT COMPLEMENT TO
What is Hydroforming?: In
Hydroforming (a unique metal forming method known as unconventional
deep drawing), material is forced on a steel punch by a rubber
diaphragm, pressurized by up to 15,000 psi of hydraulic oil.
Tooling for this process is inexpensive, unique shapes and
fine details are readily produced, making hydroforming attractive
for large or low production runs, as well as prototypes.
Benefits: Through
Hydroforming, Helander Metal Spinning Company has the ability
to form intricate shapes without wrinkles, surface lines,
thin out, or distortion in much shorter lead times than other
processes. Tooling is also very affordable ranging in price
between five hundred and one thousand dollars.
