We don't expect you to believe us, but read some of the testimonials from independent users of the COLDfire process
"As per our previous
discussion, I have monitored the results that were obtained with the COLDfire
treated punches. The results were fantastic. As you know, the granulation
I have been compressing is hard on tooling because of its corrosive and
abrasive properties. Prior to your COLDfire
treatment, I had tried untreated S-5 steel punches, stainless steel
punches and S - 5 diamond coated punches. None of the previously mentioned
punches lasted for more that 6, 000, 000 tablets and, in some cases the
punches did not even last for one shift. I am pleased to tell you the S -
5 steel punches you treated have lasted over 80, 000, 000 tablets."
"Last June I spoke with
a fellow engineer about a problem I was experiencing with our dies. The
rotary dies we had would be sent out to be re sharpened, be returned and
run for only one (1) to three (3) million cuts. He mentioned COLDfire
thermal cycling processing and your company to me as a possible solution
to our short runs. He had some good success in some other similar
applications. I took our worst case die, had it treated, and then
sharpened. We then put it into testing and we increased the die's life
four (4) times. This die was an old die - only averaging one million cuts;
the maximum cuts off it were 1.5 million. The process was very successful
in our case and will be used on all rotary dies - new and old. It will
also be tried in other, similar applications throughout the Plant."
"The situation with COLDfire
treated granulation knives is quite different. Now we can run a set of
knives for three to four months and sharpening only requires the removal
of .040" of steel. Not only do we get four times more service from
the treated knives between regrinds but in addition the material lost from
the knife during grinding is reduced by a factor of two. Regrind knives
are cut to one fourth and the expense of replacement knives is cut to one
eighth of what we experienced with untreated knives. COLDfire
treatment has proved to be an excellent investment!"
"When I last spoke to
Sid Field he was having such good luck with broaches (I think he said he
raised production from 20 pcs. Per grind to an average of 90 pcs. Per
grind and that he is planning to have you treat his large broaches"
"When we decided to COLDfire
treat all of our inventory of Amada punches and dies, we purposely
withheld on ¼"x3" rectangular punch. By doing this we could
stage a comparison test between those tools which were treated and tools
that were untreated. By COLDfire
treating our punches and dies, we are realizing a 357% increase in tool
life. Annual costs for tool grinding and replacement tooling should be
reduced by 72% compared to non - treated tooling. We recommend that all
punches and dies purchased in the future be COLDfire
treated before being placed into service"
"As you know, we
recently had the subject broach COLDfire
treated. Before treatment, we were broaching approximately 300 parts
between regrinds. After treatment we broached 1, 1000 parts, reground the
broach, and produced 2, 200 more parts before further grinding was
required. Based on this test, I strongly recommend that we send all our
broaches for treatment and investigate other areas where this treatment
could be beneficial."
reported that it takes them three to five drills to drill one hole and the
they have tried various combinations of tool materials coatings,
gometrics, speeds, feeds, etc. Your process in conjunction with Draper
Laboratories has shown unparalleled success. The improvement represents
fifty-four ¼ " deep holes per drill compared to an average of four
drills per hole, a tool life increase of 216 to 1."
"A test was recently
conducted comparing carbide, high speed steel and COLDfire
treated high speed steel and mills for roughing titanium rotors. The
present carbide tooling lasted on end mill per part. The high speed steel
end mill also lasted one tool per part. The COLDfire
treated high speed steel end mill lasted one end mill per three parts. COLDfire
treated high speed"
experienced another successful test of COLDfire
Tooling. The machine operation involved the spade drilling of malleable
cast iron. The spade drill was made from nitrided M2 M10 high speed steel.
The hole dimensions are 3 ½ " in diameter by 8" deep. Present
tool life is one hole per drill before re sharpening. Tool life with the COLDfire
drill is seven holes per drill before re sharpening. We are looking
forward to doing more COLDfire
testing on milling and drilling for next year's projects."
treated chopper blades have consistently returned average results of 2.6
times any of our previous experience. The best raising the life of the
blades from our pre COLDfire
blades of 127 km of cutting length to 478 km of cutting. The slitter
blades have similarly performed up from our previous best of 23 km to 72
km as well as highlighting a previously unknown set up problem that has
allowed us to modify our practices for greater efficiency."
"Following our testing
of the COLDfire
process on our guillotine blades we have now run through three sharpenings
and have consistently returned a 40% increase in cuts between sharpening.
Added to that the blades will also run to three times the life of any
