Powder Injection Molding, Binders

  1. Oct 30, 2013 #1
    Hi, I was just curious, I needed verification, I am reading up on PIM process and I see they use "binders" to keep the shape of the powders before sintering, anyways as I've been reading the binder consists of a surfactant, a filler and a backbone, I was just curious as to what ratios are there between these 3? I was reading on an article that 3%wt PVA was optimal for higher green densities, and from what I've read on surfactants they are usually under 1%, does that mean that the filler is usually over 95%? or is this ratio really bad?
