When to Demould Resin Lures Safely

Timing is everything when demoulding resin lures. Releasing them too early can ruin the detail and shape you’ve worked hard to achieve. Let’s explore how to know when your resin lures are ready to be removed safely from the mould.

Understanding Resin Cure Times

The most reliable way to determine when to demould your resin lure is to follow the specific curing times recommended by your chosen resin product. Polyurethane resins such as the “IWhite” – Polyurethane Casting Resin can reach initial hardness in as little as 30 minutes, while fast-curing epoxies like ICreation Fast Epoxy Resin typically allow demoulding in about 6 hours. Always check the manufacturer’s guidelines, as demoulding too early may result in warping or a sticky surface.

Best Practises for Safe Demoulding

Patience is key—wait for the resin to feel fully hard to the touch and avoid rushing the process. Some lures may appear set on the surface, but the core could still be soft. If you’re unsure, give it extra time to be safe. When removing your lure, gently flex the mould or use a soft tool to ease it out, minimising stress on fine details.

Work in a controlled environment with stable temperature.
If possible, leave lures in the mould overnight for best results.
Avoid using sharp objects to extract the lure, which can scratch or mar the finish.

When This Matters Most

If your project involves intricate detail or very thin pieces, a complete cure before demoulding is especially crucial. Premature removal risks breaking delicate fins or distorting clear coats, so this step is vital for showpiece or hybrid lures.
