Hi,
I have a lot of left-over scraps from metal machining (aluminum), and would like to cast off a few very small parts (suspension arms and the like for 1/8 scale cars / RC car size).
Is there an alternative way of mould making than sand casting, like using a suitable hi-temp silicon (eg: Wacker M4470), or is sand casting the only real option for this.
Would really like to use these alloy scraps as seems a real waste to throw them out.
Any information greatly appreciated.
Thanks,
