For the manufacture of parts that are difficult to remove from the mould, we should choose moulds of lower hardness, as they are more flexible and have excellent resistance to breakage.
All our products have Technical Data Sheet (TDS) and Material Safety Data Sheet (MSDS). Do not hesitate to ask for more information.
Although it is true that our SILCODISC moulds do not have an expiry date, we always recommend using them within 6 months of manufacture.
For optimum results in the manufacture of your pewter parts, we recommend the use of our pewter alloys, which are specially designed for casting quality parts. See our section on pewter alloys.
Applications of pewter moulds
Pewter is not an inexpensive material, it is highly resistant to elements such as oxidation and loss of shine. These characteristics make it a very popular material for the manufacture of parts in a wide variety of activities and applications.
The main sectors that use our pewter moulds are:
-
- Jewelry
- Wargames and miniatures
- Shoe ornaments
- High-quality fashion accessories without mechanical demands
- Gift items
- Maquetismo
Instructions for use
To ensure optimum results in the manufacture of parts by pewter casting in a silicone mould, it is essential that the operator’s hands, work tables and all tools are kept at the highest level of cleanliness. In addition, the original parts must be free of any traces of grease or varnish.
Thanks to the low viscosity of the mould before vulcanisation, the parts are placed in the mould in the usual way and very easily.
The following parameters have to be taken into account for the vulcanisation of the mould:
-
- Temperature: 170 – 180 ºC
- Pressure: 10 kgs/cm2 minimum. See our pressure table
- Time: 5 minutes for every 2 mm. of mould thickness
Example: taking these data into account, a 10+10 mm mould. = 20 mm thick, it would require 50 minutes of vulcanisation at the indicated temperature.
To make the mould correctly, we have all kinds of accessories such as centring devices, mould release agents, gouges of different sizes, tear-off silicone, Teflon and silicone bars, etc.
In addition, if you have any doubts about the manufacturing process of the parts, both when making the mould and the casting process, or if you simply want to improve your technique, Coniex offers centrifugal casting courses, which are given at our facilities.
Our Applications Laboratory is at your disposal for any questions you may have.
