3 simple steps to choosing the right silicone mold

It would be ideal to have a single type of mold that meets all our needs, but this is really complicated: the characteristics required to manufacture flat pieces, such as a medal or a sports plaque, are not the same as those needed to manufacture a piece of jewelry which, due to its morphology, will be difficult to extract from the mold.

When choosing the most suitable mold for the manufacture of parts in Spin Casting, we must take into account different factors such as the metal to be cast, the shape of the part and its size .

30 years as manufacturers of silicone molds guarantee the quality of our molds. In close collaboration with our customers and thanks to the work developed in our R+D+i Department, we have developed specific ranges of molds that meet the needs required in each case.

Our molds SILCODISC are characterized by an extraordinary thermal resistance (necessary for the molds to last as long as possible and to take longer to burn out cast after cast) and for an excellent mechanical resistance (flexibility of the mold that facilitates the extraction of the part from the mold without tearing or breaking).

Now, let’s see which range of molds is the most suitable depending on the three factors mentioned above:

The first point to take into account is the Metal or Alloy we are going to work with:

Depending on the metal we are going to melt, we will choose a different range:

Silcodisc-EXTRA; suitable for large or thick parts, thanks to its excellent temperature resistance, such as sports medals, large buckles, etc.

Silcodisc-BZ: range of molds designed for all types of parts, but especially suitable for parts requiring good mechanical and thermal resistance, such as jewelry parts, trimmings, buckles, etc.

RESIN parts: If what you need is to reproduce resin originals, such as 3D printing parts, and they do not resist the normal vulcanizing temperature, Coniex manufactures the series Silcodisc-MA 90 and MA 120 that vulcanize at 90º and 120º respectively.

The morphology of the piece will determine the hardness to be chosen.

However,if we have parts with areas that are difficult to demold, i.e., difficult to remove from the mold, we will choose a lower hardness, which will allow us to flex the mold and facilitate the removal of the parts without damaging it.

It is very important to always choose the hardest mold that allows us the shape of our piece, since this way we will have less deformation in the reproduced pieces.

Another point to take into account is the size of the part.

Finally, we will have to choose the diameter and thickness of the mold, which will vary according to the size and thickness of the parts to be manufactured.

At Coniex, we have different diameters and thicknesses so that you can choose the most suitable mold and, in this way, get the best performance and profitability out of your productions.

We put at your disposal all kinds of accessories and tools to make the making of your molds easier and more productive.

If you need to improve your casting techniques and increase both the quality of your parts and the profitability of your productions, sign up for the courses Foundry Courses that we give periodically.
