5 Tips for keeping your resin silicone molds in top shape

Silicone resin mold care

Using silicone molds to create your resin jewelry can open up so many possibilities!  After you have gone to the trouble of purchasing or making your resin silicone molds, you want to make sure they last.  Caring for your molds isn’t difficult, but there are a few things to remember:

1. Store your silicone molds in a single, flat layer. Storing them in a pile may cause them to bend and warp.  Once a silicone mold is warped, it cannot be undone.  Hint:  To create more storage space, use a piece of cardboard on top of a layer of molds to create a new storage layer.  Be sure to evenly distribute the molds on the next layer.

2. Store your silicone molds cool, dry area, out of direct sunlight. Excessive heat can cause the molds to warp or breakdown.

3. If you’re not going to be using your silicone mold for awhile, consider storing a casting in the mold to help insure it will retain its shape.  Hint:  if it’s an intricate mold and you’re worried about getting the model back into the mold, try pouring warm candle wax into the mold.  It should easily demold later.

4. Do not pierce holes in your mold. This may cause the mold to lose its shape.

5. When finished with your silicone mold, wash it with warm water and mild soap before storing.  Do not use solvents to clean your mold and do not place it in the dishwasher.  Make sure your molds are completely dry before storing.

Hi im very new to resin but recently purchased a few flower molds just to try it out and i cannot get them to come out without several bubbles around the edges of the pettels. i dont think its a reaction of any kind i am just not pouring it in there right i think as they look like bites taken out of the edge of the pettels. Please help! Any info is appreciated!

Two things you can do: 1. Warm up your mold with a heat gun before pouring the resin. (be careful not to melt your mold — especially if it is plastic) 2. Pour a small amount of resin into the mold and roll it around. This will help to break the surface tension and less likely that these bubbles will occur.

That’s good to know! Someone was asking me about glitter removal tricks this week.

I just got your clear silicone cone pendant mold and the opening is so small I can’t imagine how I’ll get a cured piece out without cutting the mold. How do I do this? Thanks.

Unfortunately, the mold makers we work with prefer not to share their sources.

HELP ppplllleeaasee

Recently purchased a shredder and being of a creative and art background, really liked the recycled cardboard packaging that protected the shredder from damage etc.
I remembered I had bought some silicone and catalyst and resin to have a go with. My silicone mold came out a treat however before I can create my resin cast I need to remove the thin layer of brown recycled packaging which remains stuck to the silicone even after 24hrs of cold water soaking in our bath lol!

Have you ANY idea how I could acheive this. I do have imagery should you need to see my DIY silicone mold cast into recycled reformed protective Cardboard packaging

Hi, I need help and advice. I got my mold for giant cupcake today, but the top is crushed aside. What can I do to fix it? The seller doesn’t want to replace it. Please help me!

I’m afraid once a silicone mold is crushed like that, it’s almost impossible to get it back to its normal shape without the original template.
