PRODUCTION TEST SYSTEMS

 

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 over sixty 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:
