Use with Two-Piece Silicone Molds

These clips are ideal for clamping the seam of two-piece silicone candle molds and resin molds while you pour. Align the two mold halves, then clip firmly along the seam at even intervals. The 25mm clip provides the strongest grip and is recommended for larger or thicker molds; the 15mm and 19mm suit smaller molds and finer seams. Use 2–4 clips per mold for a secure, even seal.

Frequently Asked Questions

Which size should I use for silicone candle molds?
The 25mm clip gives the strongest clamping force and works best for larger, heavier two-piece molds such as pillar or sculptural candle molds. The 19mm is a good all-rounder for standard taper and medium pillar molds. The 15mm suits smaller or thinner molds. Buy one of each size to have the right clip for any mold.

How many clips do I need per mold?
For most standard two-piece molds, 2–4 clips evenly spaced around the seam is sufficient. For larger molds — such as the Rose Tree or other large sculptural candle molds — use 4–6 clips to ensure a consistent seal and prevent leakage at the join.

Can I use these for resin casting?
Yes — these clips work well for two-piece resin molds. Ensure the mold halves are aligned precisely before clipping. For resin, seal the seam with mold release or low-tack tape if needed to prevent leakage at the join line.
