EA-Connect has participated in a project delivering parts in compliance with the Production Part Approval Process (PPAP) used in the automotive industry.
The specific parts are done by gravity casting followed by a surface treatment consisting of Surtec passivation and powder coating.
At every delivery, a material certificate, material sample, capability measurements and 3rd party analysis results, follows.
What is PPAP?
It all started in the American automotive industry in the eighties, when the American car manufacturers felt they were lagging behind in quality compared to the Japanese automotive industry. The PPAP way of thinking, was developed by a group of industrial engineers from the Automotive Industry Action Group (AIAG).
The objective of PPAP was to establish confidence in component suppliers and their production processes. It is a comprehensive quality management system, which roughly intends to ensure quality in the supply chain consisting of suppliers in several tiers.
The original goal was to make recommendations on how to improve the quality, but the project was developed into a standard. In 1993, APQP (Advanced Product Quality Planning) was developed and launched and the goal of PPAP was to ensure that the design and specifications was understood by subcontractors in order to meet the customers’ requirements in a current production.
Since the beginning, the PPAP has spread to the global automotive industry. Danish subcontractors, who wish to become a subcontractor for the automotive industry need to know and handle the PPAP.
The PPAP-project in EA-Connect includes gravity casting, passivation and powder coating
EA-Connect were approached by one of its existing customers who wanted to penetrate a part of the automotive industry as a new business area.
The parts should be gravity casted in a corrosion resistant alloy. Afterwards the parts are passivated with ChromitAL TCP, which is a chrom-3 based (trivalent) product, which complies with RoHS. Finally, the parts are powder coated and combined with the passivation, the parts have a high corrosion resistance. The parts has performed over 1000 hours in a salt spray test and provide good adherence of the molding compounds.
As a part of this project, EA-Connect had to find a gravity casting company able to comply with PPAP requirements and cast in the specific alloy. We located a supplier in China meeting these demands and completed the project with this supplier.
Supplier audits have been carried throughout the supply chain in accordance to the PPAP requirements. In a current production a material certificate, material sample, and 3rd party analysis results has to follow with every delivery.
