PRT's URGENT

Dear Experts,

I am facing a problem in PRT assignment.I have considered moulds as PRT's and i have two set of moulds for my operations.I have assigned these moulds to labor work centers.Can i consider this as two production lines?Also like a machine i am using this mould and where i have to maintain capacity for this mould if treat this as a PRT?In general i am using one set and i have more requirement i am using two sets.I can differentiate that by lot size but my worry is cani consider this moulds as PRT's and where i have to give capacities?

Looking for experts answers.

thanks in advance
