Are One Size Fits All Fixtures Undermining The Speed and Accuracy of Your Testing?
|
|
| |
|
|
Are the fixtures holding parts during tests sufficiently rigid? OR, sufficiently flexible?
Do test fixtures help simulate the real-world conditions in which a product or component operates
Are test fixtures susceptible to operator error or are they fail-proof poke-yoke designs?
These are just a few of the many fixture-related questions that InterTech’s test engineering specialists investigate when doing an in-depth analysis of a functional test or leak test system. Whenever there is a significant gap between a test instrument’s published accuracy and the real-world testing GRR fixturing is a likely culprit. And, whenever off-the-shelf generic fixtures are being used it is relatively straightforward to see and fix the square-peg-in-round-hole compromise unwittingly built into inferior test systems.
There are dozens more studies akin to analyzing fixtures that are part of an InterTech
in-depth test applications analysis for both functional and leak testing systems. Contact
847-679-3377 to initiate a NO-COST Testing Applications Analysis.

Clearing Up Some Leak Test Confusions
|
|
| |
In this column we answer questions from InterTech customers
and also take on some misleading information that
manufacturers of Brand X leak detectors have been
disseminating.
Send your questions to sales@intertechdevelopment.com.
Question: Because Internal Combustion Engines are long established
—some characterizing them as legacy technologies— there is
little reason to change leak and functional test methods used in
their manufacture— YES?
Answer: NO! Functional and Leak test instrumentation for assuring quality
of Internal Combustion Engines continues to evolve. And,
innovations in test systems originally designed for other
applications such as medical devices are sometimes equally
applicable to improving speed and accuracy in leak and functional
test systems for Internal Combustion Engines, and vice versa.
Granted, EVs grab headlines, but it is widely reported that
consumers - and especially US consumers— clearly favor Internal
Combustion Engines or hybrid vehicles.
The day when auto makers abandon innovations in cars with
Internal Combustion Engines is nowhere in sight. Why would one
straddle new car models with antiquated testing technologies that might compromise their quality before they are released to the
market?
InterTech Development Company has never stopped research
and development for technologies that improve leak and
functional testing of Internal Combustion Engine components.

"The report of my death was an exaggeration” - Mark Twain, 13 years before
his death"
For example, InterTech’s patented Bias Leak technology confirms
the integrity of the test-chamber seals at the start of each test
cycle without sacrificing cycle time. This technology alone has
potential to dramatically improve quality and yield in the
manufacture of fuel systems, valves, ignition systems and more.
Manufacturers of Internal Combustion Engines components can rely on
InterTech’s deep bench of test engineering expertise for a detailed
projection of ROI from investing in test technology updates. To schedule a
no-cost consultation on best-match test technology and methods for your
unique application requirements contact 8476793377.

Plans for the FIRST WEEKEND of FEBRUARY?
|
|
| |
|
|
Visit Chicago! Visit InterTech!
Why the first weekend of February?
Chicago becomes “foodie central” during Chicago Restaurant Week— which is more
than a “week”. To give the 100’s of world-class restaurants in Chicago their due, the
“week” actually stretches from January 23 - February 8, 2026. It’s a chance to sample
gourmet world cuisine in discounted prix fix menus throughout the city’s Michelin and
more top rated restaurants.
And, if there is one thing Chicago loves just as much as food it’s theater. There are
more than 75 shows being performed during Chicago Theatre Week— with tickets
available for a fraction of their usual price. Here too, Chicago’s “week” is actually
longer— February 5 - 15, 2026.
AHA!!!February 5 - 8 Chicago Restaurant Week and Chicago
Theater Week overlap—- discounts on food, wine,
entertainment are yours for the taking.
Once you are sated —note that — InterTech’s Test Engineering Specialists will be on
hand in InterTech’s Chicagoland headquarters the following week — February 9 - 13
—to do in-depth consultations on your testing challenges. To schedule a private
meeting with InterTech’s test engineering specialists write to
sales@intertechdevelopment.com.

Is Your Fuel Filtration System Up-to-Date??
Perfecting functional, leak and other tests to ensure both the integrity of filters,
as well as optimal testing efficiencies during production, requires a deep bench of
test engineering expertise. Read this to learn how InterTech Ex-Heat(tm) and
LeanTest(tm) technologies are impacting the efficiency of fuel system parts
production.

Downstream Matters….
Fuel injectors are just one example of products where measuring
leakage on the downstream side of the injector, rather than the
inlet, allows for orders of magnitude more accuracy. InterTech’s
patented mass flow leak testers are used to measure leakage as
a flow increase into the test circuit. These measurements will be
accurate even when test systems are pressurized up to 10,000
psig!
For more details, see these technical briefs on three fuel injector
functional test applications using InterTech’s patented mass flow
sensor technology.
