SigTrap system in-situMitsuba, Mt. Pleasant, MI and Monterrey Mexico

Mitsuba has been an IMPACT SigTrap customer since 2002.

Mitsuba uses two SigTrap NVH systems in Mt. Pleasant and two SigTrap NVH systems in Monterrey to automate noise quality testing on the production line for 100% of the window lift motors produced in the plants. Motors are tested with accelerometer sensors hand placed on the motor housing. Noise quality results are presented to the noise cabin operator for handling and re-routing of the motor.

Motor with Accelerometer sensorHi-Lex Controls, Litchfield, MI USA

Hi-Lex has been an IMPACT SigTrap customer since 1999.

Hi-Lex uses over twenty SigTrap NVH systems on the production floor to automate noise quality testing on over 90% of the window regulators produced in the plant. Motors are tested with various configurations of accelerometer sensors automatically pick-and-placed on the motors and rail assemblies of the regulators. Noise quality results are logged automatically via the plant network and presented locally to the line operators. Hi-Lex has been an industry leader in automated noise quality testing and holds two patents in accelerometer application and noise testing for window regulators (US Patent #6,842,717 and US Patent #7,050,939). Hi-Lex also tests 100% of the Power Lift Gate assemblies they produce with fully automated SigTrap NVH systems.
