Perfection Invests in Part Cleanliness for the Future

Automotive Cleanliness Standards

Vehicles are becoming much more than a means to get from point A to B. Rather, they have become a safety shield for its passengers, designed and outfitted with the most advanced of technology to make the end user’s experience safe and luxurious as well being “Driverless” with autonomous driving capabilities.

With that in mind, in electronic modules and the subcomponents of electrical all must be very clean in order to function properly and prevent circuits from shorting. Therefore, it is only logical that the zero defect requirement will be a given standard as the industry evolves with hybrid, electric vehicles and autonomous vehicles.

Automotive industrial requirements, such as VDA 19 and ISO 16232:2018, now require strict control of the quantity of residual contamination on the components supplied. Two specified factors now apply, those being “Qualitative Requirements” (Contamination by measuring mg/component through Gravimetric analysis), and “Quantitative Limits” (The measure of quantity, size and type of participles, defined by metallic and non-metallic organics). These standards are becoming the “new norm” demanded by OEMs and the Tier 1’s whom supply parts for sensitive subsystem parts used in automotive electronics, fuel systems, transmissions, etc.

Cleanliness at Perfection Spring & Stamping Corp.


Perfection Spring & Stamping has upgraded its in-house washing capabilities to meet the increased ISO 16232:2018 cleanliness requirements for automotive electronics, fuel systems, transmissions, and medical applications. The “PSS Ultra Clean System” includes multiple micro filtration processes, custom components, and proprietary engineering systems including non-recirculation for final rinse, & turbo velocity air knife for drying, all designed to meet increasing cleanliness requirements.

The requirements allow for four methods to clean parts, including Shaking, Ultrasonic Cleaning, Spraying (Pressure washing), or Flushing. As a supplier to the Automotive Market, our current state of technical cleaning here at PSS is achieved by “Spraying”, utilizing a three-stage aqueous process followed by heated forced air dryer. We have an enhanced wash process that uses de-ionized water and a unique recipe and balance of pressure, heat and rinse to achieve superior results. Though this process was once the “first of its kind” to meet and exceed customer’s needs, the time has come to change and adapt as these new stringent requirements.


We have also added the most technologically advanced testing equipment, utilizing the GT-Vision Filtrex Tester, for Qualitative and Quantitative Analysis of Particles that allows us to verify cleanliness to the most exacting standards. Not only will we be able to report to the International Standards, but as well as particular Customer Specific Requirements. The system shall be invaluable for rapid development of future cleaning protocols.
