Moulds for Concrete
We can cast jewellery concrete into molds as well.
Nowadays, concrete jewelleries are getting more and more popular among the DIY communities. Their simplicity and the unusual nature of their material make it interesting.
The molud can be prepared from a relatively wide range of plastic materials, since the concrete in general, so as the jewellery concrete does not usually adhere to any plastic.
However, we predominantly suggest silicone molds and then alternatively it can also be made from polyurethane.
The advantage of the polyurethane mold is that it has better abrasive properties and is more durable. In case we decided for the flexible design of mould for concrete, besides silicone the polyurethane elastomer is the perfect solution.
Otherwise, when a rigid, well-fitting, two-piece mould is needed then we prefer for hard polyurethane resin to hard silicone.
