  • Meeting directives, such as ELV REACh and RoHS continues to be essential requirements. QPS delivers on all of these needs. QPS complies with the conditions set forth in the ISO 9001: 2015.


    QPS helps automotive engineers to specify the right products in a sustainable world. The steady evolution of the program has enabled many global OEM’s to specify ever-higher performance standards and represents:

    • Approved applicators: Applying these products to a common audited standard ensures the same coating performance throughout the applicator base.
    • High performance: Exceeding the high demands for corrosion resistance and exceptionally consistent torque and tension characteristics.
    • Global consistency: Wherever ZinKlad, DecoKlad or XMAPP standards are applied, applicators know they are using the same high-performance products.

    What do we do?

    QPS flow chart

    We supply and develop QPS standards that meet and exceed OEM specifications. We validate applicators processes by conducting audits, carrying out inspections and testing the production output to make sure they meet pre-defined QPS standards and agreed technical requirements.

    We monitor and report results on a global scale to be able to service and continuously improve performance. 

    Why do we do what we do?

    We believe that we are able to assure a global consistent performance at a local level meeting the global OEM requirements with a select number of world class applicators.

    How do we do what we do?

    ESI Automotive has developed a unique Quality Performance System called QPS that tackles the challenges for high-performance automotive coatings. OEM’s can be confident that the same coatings and consistent performance are available worldwide.

ESI Automotive achieves 84 % power density increase in EV efficiency

[Waterbury, CT, USA, December 16, 2021] The untapped potential of implementing vehicle efficiency improvements spearheaded by a systems-level approach to vehicle design have been further proven. The research, which was carried out by ESI Automotive and engineers of its customers, involved a series of real-world electric vehicle (EV) tests. The results clearly demonstrate the efficiency benefits of using silver sintering technology for inverter designs versus a soldered solution. 

The findings are pivotal to further evidencing ESI Automotive’s vision that OEMs can generate valuable cost savings and vehicle efficiency improvements by taking a systems-level approach to the entire design and production process. 

As part of its analysis, which focused on power cycling and thermal resistance measurements, ESI Automotive supported its customer replacing soldered die attach and wire bonding to a fully sintered top and die attach design. This enabled the inverter to operate at a higher power and temperature, facilitating miniaturization with a smaller cooling system. More specifically, the new SiC power module approach resulted in an increased power density of 84% and endurance of more than 10 times. A 33.8% reduction in weight was also reported. 


Chris Klok, director of vehicle electrification at ESI Automotive says that these results are critical in demonstrating the widespread benefits OEMs can achieve, simply by switching from soldering to silver sintering for some EV designs. 

“These latest real-life results are testimony to just how revolutionary silver sintering technology is. Not only can power density and reliability be increased, but silver sintering can also have a positive light weighting effect, which drives further vehicle efficiency improvements.”  

“These results are just a snapshot of what can be achieved now, and the direction cost-and operationally-efficient EV design is heading in the future. By making the move to current SiC die technology, powertrain engineers benefit from numerous significant performance and reliability gains. This forms the foundation for optimising the traction inverter in the very near future.”

ESI Automotive utilizes ALPHA® Argomax® sintered silver, which has been successfully deployed in mass produced EV automotive inverter applications.
