SCOPE The material defined by this specification is a filled, weatherable and paintable the

3、rmoplastic molding compound. 2. APPLICATION This specification was released originally for material used for exterior ornamentation applications that are mold-in-color and partially painted (i.e.: bodyside moldings, claddings, rocker panels, wheel lips). Any color additives need to be reviewed and a

4、pproved by the raw material supplier and Ford Materials Engineering. The UV/heat stabilizers must be in the base resin from the material supplier, not in the color concentrate, for mold-in-color applications at the press. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material su

5、ppliers and part producers 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

6、was developed using virgin material properties. The use of regrind is permitted, for economic / environmental reasons, with compliance as indicated in WSS-M99P1111-A. 3.1.3 Critical Process Parameters At the request of Ford Materials Engineering the supplier shall be responsible to collect critical

7、process control data on each lot 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

8、 show that the process has remained 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. 3.2 MOLDING COMPOUND (s) 3.2.1 Melt Flow Rate 2
