Can soft super-flexible medical products be leak tested accurately and quickly?

The Challenge:

 Manufacturers of medical devices and products are being called upon to find new ways to help support homecare—proven to have better clinical  outcomes for many treatments and almost always preferred by patients. Today’s advanced wound care products that create negative pressure environments to accelerate healing are good examples.

These innovative specialty dressings deliver a vacuum at the wound site that helps draw wound edges together—simultaneously removing infectious materials, reducing edema and promoting the type of tissue growth that closes the wound.

To function properly, these dressings need to conform to the wound bed and maintain negative (vacuum) pressures. They must be soft and flexible to allow for easy application, yet at the same time maintain tight seals to preserve aseptic conditions.This is one of those situations where the adage “easier said then done” comes into play—until now……Read more with IDC new Design Report

Big Data Insights in Manufacturing

  • InterTech assists a wide range of manufacturers to identify best in-line functional test systems in the earliest stages of process development to significantly cut costs.
  • Extensive testing of your products’ functions before releasing them to the market used to be a competitive advantage.  Today this has become not just an advantage but a requirement.  End-users demand unfailing quality making pre-market release product testing a necessity.  However, testing a fully assembled product is typically a complex challenge and a costly one.  End-of-line functional testing can cost millions of dollars.  Those who instead build in-line testing into their operation – using test instruments that cost a fraction of end-of-line testing have a competitive advantage.
  • Accessing Big Data makes the competitive advantage of in-line testing even more significant.   Data-driven insights into manufacturing help identify and re-align defective processes and minimize the number of defective parts or products released to the marketplace.  Machine learning algorithms, applications, and platforms help manufacturers find new business models, fine-tune product quality, and optimize manufacturing operations to the shop floor level.  Manufacturers care most about finding new ways to grow, excel at product quality while still being able to take on short lead-time production runs from customers.,,,see IDC expertise on this engineering area….

Will it function in the Automobile as it does in the Lab?

Posted by:

  • If you are an automotive manufacturer you know that answering this question accurately is a prerequisite to releasing any automotive part to market.
  • Considering the extreme pressures and temperatures required for under the hood applications, automotive parts must be rigorously tested for proper functioning over a wide range of temperatures and pressures.  Such testing has never been a trivial matter.  The higher performance of today’s automotive parts compounds the challenges of achieving consistent GR&R in various functional tests.

The InterTech Solution:

  • InterTech Hydraulic Audit Functional Test Stands Equipped with a InterTech M1075 Functional Test Instrument  perform all tests in these varying pressure conditions and at temperatures ranging from ambient to 150°  Centigrade.   GR & R is maintained as required per ISO 16949—less than 20%

Can We Speed Up Large Volume Part Leak Testing by Eliminating Filler Blocks?

Posted by:

Oil pans require leak testing—a production step historically slowed by the relative large volume of each part.   Traditionally, filler blocks are incorporated into the test process in order to reduce the test volume making the leak test cycle both more accurate and relatively faster.  Loading and unloading filler blocks do add time to the production process.  But without filler blocks, the stabilization phase of testing proceeds too slowly and with too much error.

The InterTech Solution:

  • InterTech Development Company engineers a leak test system where oil pans are tested to a 10 sccm limit, at a pressure of 100kPa (14.5psig) within 19 seconds.
  • This fast production rate is achieved without filler blocks. InterTech’s fast oil pan leak test system includes:
  • Superior test accuracy and at faster speeds using the InterTech M1075 Mass Flow Leak Detector to control the test cycle 
Unlike generic test instruments, InterTech’s mass flow leak testers use patented sensors that are tuned to perform optimally and most sensitively within the test parameters required for testing these large volume oil pans.

When a 5 Micron hole is a HUGE problem – a White Paper from IDC

Posted by:

This white paper, “Mass Flow Leak Testing Technology Update”, is geared for engineering teams that are seeking proven methods to cut production costs without compromising product quality.  After reviewing the pros and cons of prior leak testing methodologies, we will drill into some detail re: the benefits of latest generation mass flow sensor systems that can be tuned to the specific pressure, temperature, part geometry and other application specifications. 

 Such systems can provide best gauge R&R leak testing in ranges as low as 0.01 sccm even for with parts with high internal volume high volume, and in the widest possible range of production line pressure or vacuum test scenarios.

 Key areas covered in White Paper include:

  • Historic Leak Testing Methods
  • Accuracy Considerations
  • Test Cycle Times
  • Summary – Updated Mass Flow Sensors and Application Matching

On Going Design Reports Updates from IDC on Key Technologies- Are your medical device manufacturing methods liability-proof?

Posted by:

The Challenge:

Have the hermetic seals required for your medical product to remain aseptic been compromised during manufacture? 

Have manufacturing steps such as welding unwittingly introduced blockages that prevent a device from functioning as designed? 

Are your products sufficiently leak-proof such that contaminants are kept out permanently such that sterilization steps are not undone? 

These questions and more must be answered and documented with a very high degree of certitude, not only to establish GMPs for regulators but also to ensure that your manufacturing operation is protected in the litigious medical industry.  

And, for manufacturers of relatively low margin medical products such as check valves or plastic medical bags, the same attentions to production rates and bottom lines typical in other test-intensive manufacturing lines such as those making automotive products can’t be ignored.
