Hi guys,

I've got my plugs to a stage I'm happy with and I'm about to start on the mould making. I've chosen the unimould system from easy composites. This will be my first time.

I'm worried about the release and sticking of casts though since there's a lot of 90 degree angles and sharp edges involved - this is unavoidable since its just the nature of the parts I'm making.

The part is two sided and will be done as split mould, the parting line is easy since there's a natural edge.

So far I've attached the plug to a sheet of glass and used filleting wax to seal stick it to this. Afterwards I've applied 5 coats of easy lease agents but also have both wax and pva on hand if needed. My question is what will be the safest option for a clean release. Nervous about ruining the plugs since there has been a considerable amount of time and money spent CNC'ing as well as finishing them.

Many thanks for any advice

Anthony

if you're not in a hurry you could leave the plugs to season in a warm place for as long as possible, ideally a few months!!!  That would get most the styrene out then you can pay someone to 2k coat over the top which should seal it ok and youll get away with it.

Worst case you could oven bake it to drive out the solvents but its not garunteed.

With hindsight, 2k is the better option in the future.
