Best Mold Material For Casting Resin

Best Mold Material For Casting Resin

Silicone is the best material for casting resins. It is flexible, durable, and easy to use. You simply mix the two parts of the silicone together, pour it into your mold box, let it set, and then demold your part.

Silicone also has a low viscosity making it easy to pour into small cavities and undercuts.

Silicone is not very rigid so you will want to make sure you use a support shell if you are pouring thick parts or complex shapes.

Urethane rubber is flexible like silicone but more rigid making it ideal for casting resin parts that need to hold their shapes such as wheels or gears. The trade-off is that urethane rubber is more expensive than silicone and requires a bit more prep work before pouring.

What material is used for resin molds?

The material used for most resin molds is latex. This is a natural rubber that’s extremely flexible and good at holding details. Its downside is that it’s not particularly durable, so the molds have a fairly short life span. Another popular material for molds is silicone.

Silicone can hold a lot of detail and lasts much longer than latex, though it’s more expensive. Some resin artists prefer to use urethane rubber, which also has great detail but doesn’t last as long as silicone.

The mold should be washed before use to remove any residual powder or particles that might affect the finished product. It shouldn’t be washed with soap and water because that could make the mold sticky, which would make it harder to get the resin out of the mold when you’re done casting.

Instead, wash it with rubbing alcohol, dry it off thoroughly and then dust it with baby powder so the resin doesn’t stick to the sides of the mold. You don’t need to apply baby powder every time you use the mold; only do it once after cleaning or if you notice the sides sticking together a bit more than normal.

What can I use as a mold for resin casting?

You can use almost anything as a mold for resin casting!

Of course, there are some limitations. The resin will not stick to some materials like silicone, but epoxy resins will stick to most non-porous items such as glass, metal, plastics, glazed ceramic, and more.

Resin molds can be made out of many different things, such as silicone putty or even cold porcelain. Silicone is a great material to use as a mold because it’s soft and flexible, but epoxy resin will stick to it so you’ll want to coat it with something that resin won’t adhere to. You can use petroleum jelly or coconut oil on silicone molds to make them easier to use.

Some people have used common household items such as tape and paper clips for their molds. Paper clips make great anchors for adding resin jewelry findings such as earring hooks and jump rings into the top of your casting before it cures.

You can also embed items that you’d like to include in your resin jewellery into the bottom of your mold by pressing them into the silicone mold material before the silicone has fully cured.
