Frequently asked questions about moulds

Which material is better for moulds: polyurethane or fibreglass?

It depends on the product to be manufactured and its characteristics. Polyurethane is ideal for textures and small parts that require low manufacturing costs, silicone is ideal for self-demouldable products with high added value, such as working with very complex colours and textures, and fibreglass is ideal for street furniture and large formats.

How long does a polyurethane mould last?

With proper use, good maintenance, and daily cleaning, polyurethane concrete moulds can exceed a thousand cycles without losing quality or definition.

Do the moulds require maintenance?

Yes, daily cleaning, use in accordance with the manuals, no direct exposure to UV rays, and the use of suitable release agents that do not chemically attack the concrete moulds greatly extend their service life.

Do you manufacture custom moulds?

Yes, we manufacture bespoke concrete molds based on specific design, size, and texture requirements.
