  WELDED DESIGNS
  CUT COSTS 50%
BY using steel instead of cast iron,
Dydesign engineers today make their
products more efficient ... many times at
hay the cost. Product designs are strong-
er, more rigid, take less material to build.
Too little attention is usually devoted to
simplification of product designs to elim-
inate costly manufacturing manhours
once a basic design is established. Where
designers reappraise product details for
welded steel construction, production
costs are being cut an average of 50% com-
pared with manufacture using castings.
Manufacturing operations are simpli-
fied with welded steel design. Rejections
due to inferior metal are eliminated. Less
machining and finishing are required.
Finished machines are streamlined, more
modern in appearance.
In the example below, an economy-
minded design engineer lowered manu-
facturing cost on a machine arm and cut
weight of the arm.
Before conversion to steel, the machine
arm required 182 pounds of gray iron
and cost $38.25 to cast and machine.
Welded steel design weighs only 86.8
pounds ... costs $20.06.
