The most
versatile Elastomer Tooling System for RADIUS FORMING
This system
is the result of our over 2 decades
experience in the ELASTOMER TOOLING technology
area.
The pad is designed
to exert infinitely variable (adjustable) forming pressures.
This is achieved by molding a series of holes symmetrically
for the full length of the pad. These holes are sized
and located to minimize stress in the pad.
With all of the 9 holes
left open, the pad exerts the least amount of forming
pressure. This will enable the forming of the largest
radiused shape, that the pad is designed to form.
By adjusting the forming
pressures by inserts, any radius
in between the maximum and the minimum recommended radii
can be formed.
By inserting the round
rods of the same hardness as the main pad, symmetrically
in pairs, in the outer holes, the active deflectable volume
is reduced. This will enable tighter bends on
smaller size punches.
The holes can be filled
with tubes, that will exert lesser pressures than solid
rod inserts. These inserts can be of softer or harder
grades or Rods or tubes, thus providing an infinite variety
of pressures.
This process of filling
holes can continue inwards, to increase forming pressures.
By leaving only one hole in the top row open, a 90º
radius bend of 1" can be formed, and by leaving all
holes open, a 4" radius 90º bend can be made.
Virtually any radius
punch can be used to form into this pad, as long as the
total width of punch penetration does not exceed 8"
and the depth of penetration does not exceed 4".
