Hydroforming Example Part

The part is made from .032" thick 304 stainless steel. It is hydroformed, then stress relieved and to complete the part, the flange was laser machined. The part's diameter is 3.5" and it is drawn to a 3.700" height. The radius at flange .187" and all standard dimensional tolerances are +/-.015". Typical production quantities for this specific part run from 100 to 1000 pieces.

Hydroformed Part from MuShield

This part is made by utilizing a combination of hydroforming, CNC Rotary welding, conventional fabrication and metal spinning. It is made from .030" Hi Perm 80 Magnetic Shielding Alloy. The top and bottom cones were hydroformed and the middle cylinder was fabricated. The three components were then welded together on our CNC rotary welder. After a stress relieving heat treatment, the part was spun and then laser machined to final print requirements. A final hydrogen heat treatment to obtain maximum permeability was then performed. The dimensions are 7.010" overall height. Base diameter is 3.650" and the top diameter is .890" All tolerances range from +/-.005" - +/-.010"
