With an array of proprietary straightening processes, Vestshell produces castings of unequaled precision, remarkable premium tolerances and unique process repeatability. But how?
Our specialized techniques begin in our tool and die shop, where we design and build fixtures incorporating features based on 40 years of straightening experience. The castings are then manipulated at high pressures. When these complex operations are complete, the resultant castings are consistently straight, flat, square, round or concentric within a most precise tolerance band.
Should the casting require subsequent hardening, conventional engineering wisdom would anticipate major dimensional distortion to take place. At Vestshell, the casting may need only small readjustment to move its features into a nominal condition. It is a minor operation only because the casting underwent the appropriate straightening process prior to the final heat treat.
Many special steel alloys, when processed in a normal manner, tend to crack or spring back to the distorted pre-straightened condition . . . confounding many investment casters. For these alloys with special needs, conventional fixtured straightening operations have proven inadequate since they don’t overcome the "memory" of the material. For these demanding alloys, Vestshell has pioneered complex processing regimes that address each alloy’s unique challenges. The results are consistency in performance and a dimensional stability well within the designer’s tolerance band.
