2、, HEAT STABILIZED, MOLDED IN COLOR, MOLDING COMPOUND, INTERIOR 1. SCOPE The material defined by this specification is a 25% glass fiber reinforced, impact modified, internally lubricated with PTFE, heat stabilized, molded-in-color, UV stabilized molding compound based on polyamide 66 for interior ap
3、plications. 2. APPLICATION This specification was released originally for material used for molded in color F-series seatbelt height adjuster buttons where stiffness, toughness and low friction are required. 2.1 LIMITATIONS This material absorbs and retains moisture. Part design and tolerances must
4、accommodate changes in part dimensions and physical properties due to moisture absorption or loss in the service/assembly environment. This material is internally lubricated and cannot be painted. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producer
5、s must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1.1 All requirements of this specification, identified by symbol (s), shall be met with data representing 3 sigma values using latest ISO test methods. 3.1.2 This specification was developed using virgi
6、n material properties. The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in WSS-M99P1111-A. Critical Process Parameters At the request of Ford Materials Engineering the supplier shall be responsible to collect critical process control data on each lo
7、t of material produced. Testing required will be jointly developed between Ford Materials Engineering and the supplier based on CP and PFMEA review at the time of initial approval. Annually the supplier will review the in process data with Ford Materials Engineering to show that the process has rema
8、ined under control. The data needs to be submitted in January for the previous calendar year. Data showing poor quality control measures or lack of submitted data may result in deletion from the Ford Approved Source List.
