More than 3 years of experience as a manufacturer of silicone molds guarantee the quality of our solutions for centrifugal casting. During all these years, our R+D+i department has developed, in close collaboration with our customers, a series of specific mold ranges that meet the needs required in each case.
Our molds are characterized by an extraordinary thermal resistance, which is necessary for the molds to last as long as possible and take longer to burn out casting after casting, and by an excellent mechanical resistance, which gives flexibility to the mold to facilitate the removal of the parts without tearing or breaking.
When choosing the most suitable mold for the manufacture of parts by centrifugal casting, we must take into account different factors, among which are the type of metal to be cast, the shape of the part and its size. For example, the characteristics of a flat piece, such as a medal or a sports badge, are completely different from those of a piece of costume jewelry which, due to its morphology, will be difficult to extract from the mold.
Next, we will see which range of molds is the most suitable, depending on the three factors mentioned above:
1. The first point to keep in mind is the metal or alloy to be worked with. Thus, depending on the metal to be melted, we will choose one range or another:
- For pewter parts, i.e. for tin alloys, we manufacture the Silcodisc-PE series, which is available in different hardnesses.
- For the manufacture of parts in zamak, i.e. zinc alloys, we will choose between two different ranges:
- Silcodisc-EXTRA; suitable for large or thick parts due to its excellent temperature resistance, e.g. sports medals, large and thick buckles, etc.
- Silcodisc-BZ: range of molds designed for all types of parts, but especially suitable for parts that require 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 Silcodisc-MA 90 and MA 120 series that vulcanize at 90º and 120º respectively.
- The second factor to consider is the morphology, or shape of the part. The morphology of the piece will determine the degree of hardness to be chosen.
- For flat parts without undercuts, we will opt for a mold of greater hardness.
- 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 mold with the highest possible hardness among the different options available for the shape of our part, since this way we will have less deformation in the reproduced parts.
- The third point to be taken into account is the size of the part. This variable influences the diameter and thickness of the mold, since it has to be adapted to the size and thickness of the parts to be manufactured.
At Coniex we have different diameters and thicknesses so that our customers can choose the most suitable mold and, in this way, get the best performance and profitability out of their production processes.
In addition to the molds, we provide our customers with all kinds of accessories and tools to make the making of their molds easier and more productive.
Additionally, we offer casting courses for those professionals who need to improve their casting techniques to increase both the quality of their parts and the profitability of their production process.
If you have any questions about the correct choice of a mold, please do not hesitate to contact one of our centrifugal casting specialists.
