Application Note: Transmission NVH Testing

The engine manufacturer had issues with inconsistent transmission quality causing unwanted noise and vibration. Sciemetric’s proven NVH test was seamlessly integrated onto their existing EOL test to detect issues such as, valve noise, missing bearings, timing problems, gear and loose rubbing parts in addition to having all data stored in a central location for complete traceability.

Application Note | Piston Cooling Nozzle Assembly: Test Verification Using Signature Analysis

Sciemetric’s process monitoring system was used to successfully detect piston cooling nozzle defects early in the assembly process. Detects all missing, blocked or obstructed cooling nozzles, measures high and low pressure and provides real-time ‘PASS’ or ‘FAIL’ results to the operator. Installation of the system resulted in the diesel engine manufacturer, decreasing end-of-line repair costs, customer warranty claims and more. Read the Application Note to learn more.

Application Note: Verification of Piston Type & Orientation Using Laser Scanning

A major automotive integrator was unable to test any one of four engine blocks right after piston insertion and defects being found after final engine assembly were causing expensive teardowns. Sciemetric easily installed a test and analysis system using laser scanning to verify the engine blocks to ensure correct positioning and accurately find defects such as under or oversized and bent pistons.

Application Note | Fuel Injector Insertion Verification Using Force Monitoring

Fuel rail defects for a leading automotive manufacturer were traced to the improper insertion of fuel injectors into the fuel rail. The recurring defects were not found until late in assembly and represented a potential warranty issue as the injectors and fuel rails would experience premature wear due to the improper insertion. This risk along with high teardown and repair costs led the manufacturer to look for an efficient, reliable and effective way to monitor the simultaneous insertion of the three fuel rail injectors into the fuel rail. Read the Application Note to learn how Sciemetric fixed the problem.

Application Note: Short Block Crank Torque to Turn Test

A major engine manufacturer was experiencing customer complaints and costly warranty repairs and quickly required a solution that could detect defects early in the Short Block assembly process, specifically defects caused by crankshafts. Sciemetric’s Short Block Crank Torque to Turn test measures the torque as the crank is rotated, applying advanced algorithms for consistent and reliable detection of defects such as contaminated bearings, debris, incorrect fit, bent or nicked cranks, etc. Read the Application Note to learn more.

Application Note: Dispense Operations

Downstream issues on the production line with leaks, non-secure parts and components, or unwanted noise and vibration can often be traced back to a flawed fluid dispense operation. The Sciemetric solution, using digital process signature analysis, allows manufacturers to identify faulty dispense operations as they occur and take corrective action. The result is reduced downtime, scrap, rework costs, warranty claims, and improved production efficiency and product quality.
