One of the biggest challenges platinum casters face is whether a not a model will cast. We frequently receive models that are not castible. Why gamble with profits! The worst case scenario is to pay someone else to grow the model (growing typically leads to more problems in castings, but more on that later), then pay to have the model shipped (meanwhile the clock is ticking toward the due date), then have us call you and either tell you "It won't cast," or, "It's on the bleeding edge." Now, you're out about $150 and some time. The last thing we want to do is add to the pain, but we're guilty by association... Not the type of business we like doing; business should be fun and mutally beneficial with both partys feeling good in the end.
So we've built our built our business to address this problem in regards to outsourcing platinum casting. In essence, we exist to bring designs to life - to help you make them work, and work well. It's really what engineers do, and I don't mind saying that our experience has led us to become an "engineering service" of sorts. We have we've built a state of the art CAD/CAM shop, winning awards for technical merit and rendering, established rock-solid processes and systems to achieve great results. The point is that we know how to make platinum cast - and we want you to have a great experience behind the bench - no endless burnishing and screwing around with porisity from hell!

Are your models designed to cast in platinum?
2) Polishing compound present on fingers when handling wax: Remember why you send your polishing dust to the refiners? Well, all that gold gets transported into the wax by the oils in the polish! Just like a sponge;especially with injected wax. Therefore, no amount of surface cleaning will help (seriously), and your casting result can expected to be full of surface defects. Would you rather spend a whole day or an hour cleaning your castings?
3) Orange-clean/ orange/citrus smelling solvent. This produces a chemical reaction with the investment and will result in horrible surfaces. Instead, use isopropyl alcohol. Do not clean your waxes in the ultrasonic unless it's dedicated for that purpose (and not jewlery repair).
