Shanghai International Automotive Manufacturing Technology and Material Show

Posted by:


IDC recently attended and had a great show/expo at the Shanghai New International Expo Center on Sept. 5-8, 2017.

 As Asia’s leading exhibition for Automotive Materials, Design, Technology and Equipment, Quality and Assembling, and Engineering and Service Technologies,- the Engineers and decision-makers of well-known car manufacturers and Tier 1 suppliers from China / Asia gathered together at AMTS 2017 and attracted 80,000 professional visitors, with about 800 exhibitors from China and other countries exhibited on the biggest exhibition area of 80,000 square meters.


Are Your Leak Tests Being Slowed by Long Stabilization Phases in Test Cycles?

Posted by:

The Challenge:

Leak testing windshield reservoirs is challenged by the large volume of each part.  Unlike parts with small volumes, the time required to stabilize test conditions is always longer when such large volumes are involved.

Even the best pressure decay leak test systems prove slow—and typically are far too inaccurate—because of this requirement for time to stabilize test conditions in large volume parts.

Mass flow test systems are inherently superior because they are less affected by temperature and pressure variations.  However, not all mass flow leak test sensors are alike.

Further, the ever-present drive to eliminate fat wherever possible in leak test methods are such that InterTech’s world-renowned test engineering specialists asked…contact IDC for more info….

Can We Speed Up Large Part Leak Testing?

Posted by:

Leak testing large volume automotive components –transfer cases, oil pan assemblies, reservoirs , intake manifolds, and transmissions, and the like– poses a different set of challenges than those of testing smaller parts.   Some automotive manufacturers have straddled their operations with antiquated pressure decay leak test methods for such large parts.  Pressure decay, or differential pressure decay testing, is rarely a best match leak test method for large parts because the larger the part volume, the smaller the change in pressure for a given leak rate.  With pressure testing, as you increase test volumes the result is inherently long test times AND increased measurement errors.

Using mass flow leak testing methods for large parts is always faster with acceptable gage R&R easier to achieve.  However, a vigilant eye on how production rates are impacting the bottom line is compelling many manufacturers of larger automotive parts to ask – contact IDC for info……

One leak tester from InterTech does the job of many specialized instruments and is ideal for quality control in the lab

Posted by:

  • The difference between this test instrument and others in the industry is a design breakthrough that eliminates the need for part volume matching as required in pressure decay methods.
  • “This is a transformative development in leak testing applications that require quick changeover and flexibility,” said InterTech President, Mr. Jacques Hoffmann. “It changes fundamental issues. We eliminate the need for specialized leak testing instruments in the lab. Now, the same instrument can be used for a large engine casting or a small solenoid – just change the part and go.”
  • “Whether it is incoming inspection, product development or supplier development, this is how to control costs and stay flexible, and more elegant compared to custom instrumentation dictated by part size or material properties,” said Mr. Hoffmann. “Now, with one leak test instrument from InterTech, quality engineers have more flexibility than they’ve ever had.”
