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?Image
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.
REACh compliant coatings to meet cyclic corrosion testing
Cyclic corrosion testing
More automotive companies are in the process of specifying cyclic corrosion testing to assess long term fastener coating performance. Typically, these tests comprise of 24-hour cycles of salt fog, elevated temperatures and high humidity. These tests can extend for more than 40 cycles. They are regarded as an aggressive accelerated test regime and require high performance coatings to be able to withstand the testing procedures. Coupled with this, any coating must also be REACh and end of life vehicle (EoLV) compliant.
Zinc-nickel alloy finishes are a preferred coating to meet these test regimes and environmental directives. Compared to alternatives, such as organic-based coatings and zinc only, these finishes offer more control over the thickness of coatings and virtually eliminate zinc corrosion products.
These factors allow coating engineers to specify high performance protective finishes even on fasteners with fine dimensional tolerances and recessed heads. Zinc-nickel is also proven to reduce the damaging effects of hydrogen embrittlement – a frequent problem with coatings for exterior fasteners. It also provides an excellent basis for a black coating with extremely good aesthetics.
Predicting this requirement for higher coating performance, ESI Automotive launched the range of ZinKlad 1000 finishes. These silver or black range of finishes combine a homogenous metallic zinc-nickel (12 – 17% nickel) deposit of 8 microns minimum thickness. This hard-metallic coating is further protected against the formation of white corrosion products by the application of TriPass ELV trivalent chromium passivates. Finally, a dry film Torque ‘N’ Tension lubricant is applied to both further increase corrosion resistance and modify the surface properties to ensure uniform torque and clamping characteristics.
To meet ever increasing demand for high performance zinc-nickel coatings, in 2019 MacDermid Alpha Automotive confirmed the increased capacity for ZinKlad 1000. In Europe several new plating lines have been approved for this system. This increased availability will give further unrivaled support for automotive manufacturers in the region.
In summary today’s fastener design and corrosion engineers are faced with the challenge of specifying coatings which meet aggressive cyclic corrosion test criteria, be environmentally compliant and meet their friction requirements. ZinKlad 1000 zinc-nickel system is hexavalent chromium-free and meet these industry demands for the highest performance coatings.
