Why choose silicone mold or silicone vacuum casting?

It is possible to obtain parts of exceptional quality, comparable to injected components, but at a significantly lower cost by using silicone mold and vacuum casting techniques. Because of this, the models produced by Silicone vacuum casting are particularly well suited for functional testing and final validation testing, as well as for marketing reasons and the fabrication of final parts in small batches and a silicone mold allows us to produce between 15 and 20 parts before deteriorating. As a polymer with viscoelasticity, silicone is classified as a synthetic elastomer by the International Standard Organization (ISO).

How long does Silicon mold last?

This silicone mold will stay for six months on the shelf if it is not opened or used. However, after you have opened the package and exposed the “A” side to the air, you must use the product within sixty days otherwise it will spoil. This is because the catalyst is located on the “A” side of the container, and the container will begin to cure slowly after it is opened.

Is it possible to remove silicone molds from the air by vacuum?

Incorrect mixing can cause air to be introduced into your mold-making mixture before it has a chance to be put into the mold. Stir steadily and slowly, taking care not to include air into the mixture. If there is still air in the mixture, it can be extracted with the help of a vacuum. Simply combine the mold-making material and place it in a vacuum chamber to create the desired mold.

Follow the below instructions:

  1. When you start mixing, use a container that will allow your mixture to double in size without spilling over the sides.
  2. Once part A and part B have been fully combined, place the mixture in the vacuum chamber and turn on the vacuum pump to begin the process.
  3. As soon as the air is removed from the substance, the material will begin to rise. Allow the vacuum to reach its full capacity before releasing it two or three times to ensure that all air has been evacuated.
  4. Final step: Carefully release the vacuum one more time, then remove the de-aired mold-making mix from the chamber and carefully pour it into the mold cavity.
  5. However, this technique can only be used with materials that do not harden immediately after being exposed to heat.

Is Silicon Safe to use?

Silicone is a completely safe material. According to the Food and Drug Administration, food-grade silicone cookware and utensils do not result in dangerous chemical contamination of meals. Silicone is not regarded to be a combustible material. When exposed to extremely high temperatures, it is capable of catching fire and igniting and burning. Silicone vacuum castingin which silicon mold can be made within one day. 

Why does Silicon mold color change to white?

One of the drawbacks of silicon is that a powdery white residue accumulates on it. It is Calcium Sulfate that has been related to the residue, which means that the residue is essentially associated with the chemicals present in hard water. It’s similar to a mineral deposit.
