Hi,

I have a received a drawing for an Injection moulded part that requires a surface finish of 'E8' to all A-side surfaces.

Personally I am only familiar with the SPI fininishes i.e. A-1, A-2, etc through to D-3, Would someone be able to tell me what E8 is equivalent to or direct me to where I could find relevant information on such grades?


Thanks in advance,


Lee
