FAQs

Why could the silicone mold be reused only for a few times?

Maybe you will confuse about this question for years. Here we share you some following reasons:

  1. Addingtoo much silicone oil into silicone rubber. Silicone oil is an additive which will destroy the molecular weight of silicone rubber and reduce the tension and tear strength.
  2. Addingtoo much catalyst into the silicone rubber when you make the molds. For the condensation cure(tin catalyst) silicone rubber. we suggest you add no more than 2% of catalyst. If you 1add too much catalyst, the operation time will be too fast to operate ,which will also reduce the tension and tear strength.
  3. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.

 Why does the silicone mold get burnt out?

The silicone mold get burnt out because you have left out the important notes when using unsaturated resin materials to produce your products. The unsaturated resin produces great heat when added the curing agent. So you must demould the product within 3 minutes to avoid this problem.

Our DC silicone rubber has add a special material which can resistant high temperature to make the resin molds. Help our customer avoid this problem. 

Why does the silicone mould appear to be dry outside but wet inside? 

Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.

Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.

Why is the tear strength of the silicone mold weak? 

There has three resons:

Firstly:In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.

Sencondly:you may add too much catalyst into the silicone rubber,we suggest customers add catalyst no more than 5%,2%will be perfect.

Thirdly:you may use the silicone mold too early after it finished.we suggest the customer begin using the molds after 24 hours. whatsmore,it will be better if you can make a outmold to protect the silicone mold.
