Notes:
1) Fluidity(Raschig)and Shrinkage are determined by supplier and user, Above
     index are only for reference.
2) May not be pre-heated before moulding, But should be degased one or twice.
3) The moulding condition can be adjusted according to actual size, thickness, usage
     of products and different moulding equipment. In principle, the quality of finished
     products can not be decreased.
4) Above Moulding  reference  condition are only instruction and suggestion. Because
     the quality of our products are keeping improving, The techincal data are
     changing, Sorry for no advice again.
