HYDROFORMING
Sometimes referred to as “fluid forming” or “rubber diaphragm forming”. Process developed to manufacture small to medium quantities of deep-drawn parts. Compliments other techniques of metal forming for example metal spinning, stamping, and fabrications.
• Low-cost, high accuracy production of deep drawn parts,
especially for parts with asymmetrical or irregular contours.
Attractive alternative for cost sensitive and low volume production.
• Maximum depth of 7″
• Maximum diameter of 12″ for the drawn shapes.
• Prototype and developmental components or production qualities.
Advantages of Hydroforming
• Deep-drawing, using the Hydroform method, requires only a draw
ring (blank holder) and male punch.
• Set-up is quick and simple.
• Flexible rubber diaphragm minimizes and eliminates draw marks
and increases surface finishes due to being formed into rubber.
• Two or three conventional deep-draw operations can be replaced
by one Hydroform operation.
Specific Advantages
• Inexpensive Tooling
• Versatility in Forming Complex Shapes and Contours
• Minimal Material Thin-out
• Fewer Operations Required
• Savings in Tool Materials
• Fast Tool Changes
• Savings in Finishing Costs
• Materials Versatility
• Precision
• Ease of Design Change
• Low Work Hardening
