PORTABLE AIR BRAKE LEAK TEST SYSTEM
A truck manufacturer needs to leak test installed air braking systems to ensure they do not leak and meet federal leak rate standards for commercial vehicles. The system requires semi-automatic operation; requiring the operator to make only necessary connections to run the test. The system can be configured to use on-site shop air or execute the test on a pre-charged air brake system using the vehicle’s air. For this application a customer supplied Vehicle Automated Test (VAT) system will manage and execute the air brake test. Pass/fail test decisions are system controlled.
Cylinder Head Leak Test System
An engine component manufacturer needs to test cylinder heads to ensure they meet performance specifications. The cylinder heads are aluminum castings that need to be checked for cooling flow and passage leaks. The test system will provide two dedicated stations to independently flow and leak test ‘Front’ and ‘Rear’ heads on demand. Testing will be performed on un-machined castings to ensure the parts conform to specifications before machining and additional cost is added to the part.
Multi-Part Concurrent Non-Compliant Balloon Catheter Testing
A medical device manufacturer needed a semi-automated system to test non-compliant PTA and PTCA Balloon Catheters. The tests include pressure decay testing at 425 psig and vacuum decay testing at 12 psiv to test the catheter both before and after installation of a metal stent over the balloon.
Medical Multi-Lumen Cather Leak and Flow Testing
A medical device manufacturer needed a test instrument to test single, dual, triple and quadruple lumen CVC & PICC Catheters with female Luer fittings. The distal ends of these Catheters are tipped and skive holes cut into each lumen. The manufacturer requested automated testing that would be initiated by the operator and run through the complete test without operator intervention. Each lumen is independently tested for cross-over leaks between lumens, exterior leaks and grade the degree of blockage of each lumen. The device manufacturer also wanted the flexibility to simultaneously run either: 4 single lumen catheters, 2 dual lumen catheters, or either 1 triple or 1 quadruple lumen catheter each test cycle.
Helium Recovery for Hard Vacuum Helium Test System
Manufactures lose helium on every test when using Hard Vacuum Helium Leak Test Systems. The amount of helium used and lost in the test is proportional to the part size, test pressure, and quantity of the parts manufactured. In the last few years the price of helium gas has increased as much as 500% due to shortages and transportation. The higher cost of helium gas makes a CTS Helium Recovery System a better fit for a broader range of applications for environmental issues, improve manufacturing efficiencies, and help reduce manufacturing test costs.
Engine Final Assembly Leak Location
Manufactures use Leak Location Systems to isolate exterior leaks when standard Engine Assembly tests detect unacceptable pressure loss in the systems. Leak locating systems should be easy to operate, locate the leak quickly, and provide a relatively low cost method to pinpoint external sealing problem and/or identify a defective component.
Engine Final Assembly Leak Testing
Manufactures perform leak testing on engine final assemblies to ensure they meet specification to avoid expensive warranty claims. Testing routines are conducted on air/oil, fuel, and coolant cavities to determine the engine is properly sealed and to ensure there is no internal cross contamination of cavities and engine systems.
Brake Hose Testing
Market Driver: Safety is high on the list of concerns for today’s manufacturers especially those who manufacture brake components for commercial vehicles. Hose failure under pressure and fluid leaks are among their top concerns.
Market Driver: The customer needed an inexpensive method to leak test automotive radiators. The existing process utilized helium mass spectrometry, and previous attempts to utilize pressure decay or mass flow resulted in long cycle times and poor Gage R&R (reliability and repeatability) in their production environment. The customer produces multiple designs of radiators and requires interchangeable tooling that is quick and easy to change.
High Speed, on-line container leak testing
Market driver: Sports drinks and other premium beverages have significantly increased in popularity which has resulted in new bottling plants being developed to meet the geographical market needs. Additionally, blow molders are trending toward lighter weight container designs that increase the need to check for defects that could result in a leaking container.
Solar Power Tube Testing
Market Driver: There is a growing demand for green or clean energy sources. Solar panels are gaining market in commercial and residential use.
Fuel Cell Testing
Customer: As the world's demand for energy increases, new energy sources are being researched and developed, specifically alternative fuels, including hydrogen. And now with the manufacture and commercialization of stationary electric power generation on the rise, multiple manufacturers are discovering CTS’s foothold on the leak and functional testing of hydrogen fuel cells.
