Hoping there's a few folk with an answer for this....
All the games I publish have laser engraved, polyresin dice. I've used the one factory since the first game and they still make dice for me today.
Our first game (Pocket cricket) has an injection mould which reduced the unit about 45% - good but a hefty outlay. It has paid for itself though now.
Follow up games don't have a mould. With 6 games, the outlay would be too much. I simply have the dice engraved on smaller runs. The price is obviously higher, but I can change the die faces for any reprint or additions etc. I'm not locked into to the mould...
Recently I tried a new factory in China for a quote. From what I know, acrylic dice are cheaper than polyresin, but are more difficult to engrave...or so more than one factory has told me.
Quotes for acrylic dice also included an additional mould fee....
So leads me to my question.....if the dice are being engraved, why the mould fee?
Is there no engraving in this case, is it simply a cheaper resin mould?
Whatever the reason, the quote from the new factory was no cheaper per unit price with my current factory, and it had the mould fee on top of that.
I know this is an old post but do you still have the need to have the polyresin dice manufactured...if so I represent a company based out of Holland that employs Injection molded resin products from moulds....we don't charge for the moulds.
One of the main differences is that when working with the materials, resin is more prone to capturing air bubbles which will leave some undesirables on the dice - if they are translucent. For dice that are not translucent, that won't be an issue. Other than that, they are more or less the same.
