Safe Ways to Cut Silicone Moulds

Choosing the Right Tools

A sharp craft knife or scalpel is the best option for cutting silicone moulds. The sharper the blade, the less force you’ll need, which minimises the risk of slips or jagged edges. Always ensure your cutting tool is clean and dry so it moves smoothly through the silicone.

• Use a fresh, sharp blade for clean lines
• Consider a cutting mat to protect your work surface
• Keep blades away from your body at all times

Making Safe and Precise Cuts

Begin by planning the cut on your mould—mark guidelines if possible. It’s safer to make several shallow passes with your blade, rather than trying to slice through in one go. This approach gives you better control and reduces the risk of accidental slips or tearing the mould.

Never force the blade. Take your time and work slowly, keeping your hands steady and out of the cutting path. For situations where visibility is key, using a translucent silicone like Pure Mould can help you trace your lines more accurately.

When Safety Really Matters

Extra caution is required if you’re cutting around detailed patterns or near fine undercuts, as these areas are more prone to damage. For projects demanding repeated precision, selecting a high-quality, durable silicone mould helps maintain performance over time and withstands careful cutting when needed.
