Your silicone moulds release the chocolate without a hitch, but your products never have that shine that makes them stand out on the shelves. If you’re unsure which professional chocolate mould to choose for your production line, the answer isn’t a matter of preference, but of technical common sense once you know the ins and outs.
Whether you’re producing signature chocolate bars, mass-produced sweets or filled moulded pieces, the choice of your professional chocolate mould makes all the difference: the finish, the demoulding speed and the breakage rate on your production line. This guide explains how each material works, when to choose it, and how to ensure a smooth production process.
Professional chocolate moulds: how does chocolate react during demoulding?
Before comparing the two materials, it’s important to understand what actually happens during demoulding. As it cools, tempered chocolate shrinks slightly and naturally releases from the mould walls.
This shrinkage is sufficient with perfectly tempered chocolate and a rigid, smooth mould. However, as soon as the tempering is imperfect, or the piece has a complex shape, this shrinkage is no longer enough: a good professional chocolate mould must then ‘assist’ the demoulding process slightly. This is precisely where polycarbonate and silicone take opposite paths.
📌 Key takeaway: the more controlled and consistent your tempering process is, the more cost-effective polycarbonate becomes. The less consistent it is (multi-product production, variable output, rotating shifts), the more silicone helps to minimise waste.
Polycarbonate or silicone: which professional chocolate mould should you choose?
Here’s how each option works, and in which production context it is the right choice.
The professional polycarbonate chocolate mould: shine, at the expense of precision
Polycarbonate is a rigid, transparent plastic that has been used for decades by chocolatiers for its perfectly smooth surface, which gives the chocolate a mirror-like finish and sharp edges.
How does it work? Tempered chocolate shrinks as it cools and releases itself from the smooth sides, without the need for a release agent.
The tip that makes all the difference: follow a precise tempering curve (around 31–32°C for dark chocolate). Without it, the piece will stick and break when removed from the mould.
Ideal for: premium chocolate bars and display pieces, where shine is a selling point.
The professional silicone chocolate mould: simplicity that changes the pace
The silicone flexes slightly when removing the chocolate from the mould, which helps to release the piece even when the tempering isn’t perfect.
How does it work? The flexibility of the material absorbs the uneven shrinkage of the chocolate, without the need for a release agent or excessive tapping.
The tip that makes all the difference: chill the mould for a few minutes before demoulding to achieve an even cleaner finish on complex shapes.
Ideal for: decorated, filled and embossed shapes, and high-volume production where breakage is costly.
