Hi all,
Had an excellent conversation with my tutor the other night about the casting services that companies like Weston Beaumont, Niagra Falls, Merrell etc. offer. However, I have come away with even more questions and was wondering if you guys could assist?
I would like them to cast from a metal master, and it would be quite delicate work. (Example piece attached. It's approx 35mm in length, and the square wire at the top has the largest overall width of 1mm. I estimate the filigree wire at .8-.9mm diam. All comments, hints and tips welcomed at is my first piece using this technique!) Therefore, if anyone can answer them, my questions are:
- What are the original mould creating charges for these or any similar company at the moment?
- What are their minimum orders in terms of price / quantity of design cast?
- I've heard differing sprue lengths can add ££s to the cost and vary wildly from company. Is there any way of finding out who's particularly good / bad for this beforehand?
- I know how to project metal weight using weight of wax and a metal's specific gravity (thank's Mr. McCreight), but is there a formula to calculate silver or gold from a copper master?
- What other sort questions should I be asking when I phone for a chat?
Thanks everyone
