So I did an epic casting run last night and ended up with the usual pile of sprue on the floor..
I did a few quick caculations and its pretty horifying- approx 50-70% of the resin I pour goes into sprues and then in the bin.
So If I buy 10kg of resin, only 3-4kg gets shipped to customers.
I need a way to recycle the sprue.. obviously it cant be put into small parts again, but next year Im planning to release a range of terrain and vehicles, which will be much larger molds.
Im thinking I can get a big food processor/blender, or maby a mechanical meat mincer? and turn all my scrap sprue into a pile of small peices of resin. These could then be dumped into larger molds, taking up at least half the volume or more. The new resin should in theory then flow round all the scrap stuff and when it demolds, be indestinguisable from a "pure" component.
Questions-
has anyone tried anything like this?
Would the larger parts being 60% or more recycled sprue resuly in a loss of strenght? or would the new resin bond strongly to the old stuff?
Ideally Id like to be able to completly recycle all my waste resin, as Anvil Industry grows, the ammount of resin I use, and the cost of it, is going to increase dramatically (fingers crossed) and I need a way to deal with it.
