I am a noob to the casting and printing world. Hope questions about moulds and resins are OK on this forum.
There is an enclosure for y electronics project that I am currently using; it is made of ABS plastic, rather small (130mm x 22mm x 65mm) and requiring quite some machining - 15 -20 minutes worth of it on each piece. The enclosures are inexpensive as they are but all the machining is rather time consuming, not to mention that i am not able to do the cleanest job in the world with my tools.
So I was thinking about two ways to cut down on my workload and get finer results:
Make a hard (resin?) mould and accurately drill that one, then use it for drilling the premade ABS enclosures.
Make a silicone mould (actually two or four such moulds) and use them to pour new enclosures, already shaped and drilled to spec. Such poured enclosures would be made out of a resin that resembles plastic (or maybe liquid aluminum if I could work out the screw holes to accept screws).
Does any of the two sound like a good idea ? I shall have small runs of maybe 50 - 100 pieces / year.
