Supplier Quality Guidelines - Heinrich Huhn GmbH & Co.

4 Product/Process Development
4.1 HUHN-Specific Products/Processes
HUHN strives to involve the supplier in the developmental process as early as possible. This applies in
particular to application-specific products/processes.
By means of mutual development (within the framework of simultaneous engineering) and close cooperation
from the product development stage right on up to initial series production, not only are R&D times reduced,
qualitatively and economically optimised solutions are created as well for both companies. Potential sources
of error can be avoided by implementing appropriate measures during the R&D phase, and prerequisites for
technically stable, reliable manufacturing processes can be fulfilled.
Objectives of cooperative work include:
� Reduced R&D time and costs
� Realisation of the most cost-effective solution
� Top quality, durable and especially environmentally sound products
� Minimisation of the risk of error
� On-time launch of series production with technically mature products
� Avoidance of product liability risks
HUHN provides the supplier with all necessary information.
In particular this includes:
� Specification (drawings, delivery specifications etc.)
� Intended purpose
� Special and particularly important features for functions and assembly
� Packaging and shipping requirements
The supplier must make the following contributions during product/process development:
� Suggestions which serve to:
– Avoid potential errors
– Reduce costs
– Improve the product
– As well as suggestions for special and important characteristics within the framework of the
supplier’s design/process FMEA
HUHN carefully examines these suggestions and corrects the affected specifications accordingly if
necessary, in accordance with customer requirements if applicable.
� Feasibility studies
� Design tests (engineering tests, design certification)
� Design FMEA
� Process planning
� Process FMEA
� Process capability analyses and substantiations
� Process validations (qualifications)
� QM plan (inspection plan): As a rule, a plan must be prepared and submitted for the following 3 phases:
– Prototypes
– Pre-production series
– Series production
� Test equipment planning
� Production equipment planning
� Packaging suggestions
Completed records subsequently become an integral part of first article inspection documentation. Records
must always be kept in German, although another language or a translation may be agreed upon within the
framework of the respective project.
When the project is launched, the product/project timetable must be coordinated with HUHN. The supplier
