Resin molds and silicone resin molds?

Should I use silicone resin molds or resin molds for crafts and my resin jewelry?

That is a such a great question (and an important one). It’s undoubtedly important to be aware of the advantages and disadvantages of each mold type.

Understanding the constraints of each is vital to making sure that that you achieve the results you desire, although both kinds of custom plastic molds can operate with some resins.

Plastic resin molds

These resin molds stand made from polyethylene or polypropylene sheet vinyl. They are produced from a template and are flexible.

Advantages:

Inexpensive. Plastic molds can survive obtained for less than $10 each. (Many for under $5!) Once you damage a pattern, this is good, you not to replace it.

Easier to work. Molds are an excellent place for resin crafters that are new. They aren’t complicated (nooks and crannies) and are easier to care for when compared to silicone. (wash after use and allow to dry)

Disadvantages:

Castings won’t be bright. Once it happens removed from the mold, the surface won’t be shiny. You will cover with a coating of resin gloss sealer spray or have to recoat with another layer of resin.

Can be scratched. Something like a toothpick or a fingernail can leave a gouge that is noticeable if you are not careful.

Challenging to create your own. It is going to be impossible for you to make your resin molds unless you’ve got a high tech system that lets you mold the plastic.

Silicone resin molds

If cared for correctly, these resin molds are created from two-part silicone and can last for years.

Advantages:

Very flexible. Molds permit you to do intricate castings which may be removed compared to images.

Custom Molds. You may buy two-part silicone yourself and mold anything you want to (assuming you have a version).

Castings may come out shiny. I say may here has to be brilliant. When it is (like with our geometric silicone resin molds), then your casting should come out just as polished as the first.

Disadvantages:

Expensive. Molds are at least two to three times the cost of an impression. Silicone costs than plastic.

Molds have to imply cleaned after use. They should be kept flat.

May require vacuum casting. When projecting it unless you are using a silicone mold, you may not see the bubbles. You may request resorting to using a vacuum casting setup before the resin starts to heal, to be specific all your bubbles are out.

Which sort of resin mold should you pick?

I will go with a mold if you are a beginner. They are cheap, and if you make a mistake (such as your resin does not heal), you are not out plenty of money.

As soon as you get experienced, there is a silicone mold a ‘collection piece’ to enhance your mold collection. It will last for hundreds of castings. Hint: If you create a cast you want it to be shiny and that you love, finish the casting, get the glow you like to mould it.
