Today, most assembly machines include test stations and fixtures throughout the assembly process. Final tests often include the mechanical actuation of a part, leak testing of a chamber, hose assembly stress testing, or checking for the presence of various components that make up the finished assembly.

PURITAN has been building production test systems for nearly fifty years, tailoring our designs to accommodate the new and ever-changing philosophies and principles of assembly and production-test.

  • leak testing

  • mechanical functional test

  • electronic functional test

  • resonance and harmonics

  • guaging

  • vision systems

Some  examples of our design and build capabilities can be seen below:


Wash Fluid Heater EOL Test System

  • simulated ‘in-vehicle’ operation

  • programmable PSU to simulate ‘dying’ battery

  • good/bad part determination

  • barcode reader / audit

  • uplink to facility MIS system

  • leak test

  • leakage current test

  • pressure / pump test

  • current / voltage draw

  • color recognition of wiring

  • fast cycle time

Seat Recline Test System (In Process Test)

  • manual testing of production seat frame – ambidextrous

  • go / no-go pass / fail determination via precision measurement & test

  • precise & traceable calibration to meet PPAP requirements

  • intuitive operator user interface

  • data logging, storage, & retrieval
