Hi im looking for a resin to use for a short run of chassis for a handheld project im working on, injection moulding has been considered but I'm really uncertain the amount of sales is going to be high enough to warrant the costs... So for a small run I'm possibly looking into casting the chassis...
Do you have any resins that have similar thermal and strength properties to plastics like ABS? Shatter resistance scratch and dent resistant with some mild flex for durability? But can also accept pigments and is capable of being cast with a glossy smooth finish and or dusty grainy mass finish?
I will also need some help picking mould making rubbers or even plasters...
If you have anything like that please let me know.
Thanks
Simon

As long as the detail is not too deep then the resin will fill it no problem as it is quite runny.
With matt finishes, be aware your silicone mould will mechanically grip the part slightly so may need peeling off a bit more carefully and may have a reduced lifespan. You can mitigate against this a little by rubbing some pure silicone oil onto the mould or using a silicone release spray.
