Silicone moulds SILCODISC-PE

Manufacturing parts in PEWTER (known as white metal) using Spin Casting requires an adapted range of moulds.  The SILCODISC-PE series has excellent mechanical strength and tear resistance, which guarantees a very long mould life. They are specially designed and formulated for the spin casting of low-melting-point metal alloys: Pewter and lead. They are also suitable for the centrifugation of RESINS.

The main sectors used are:

  • jewellery
  • wargames and miniatures
  • shoe decorations
  • gift items
  • modelmaking

Our SILCODISC-PE series of moulds is characterised by:

  • Extraordinary resistance to tearing.
  • Low viscosity before vulcanization (raw) that facilitates handling when preparing the mould and hammering parts, minimizing the “rebound” effect.
  • Great flexibility, which allows the demoulding of complicated pieces.

High resistance to metal abrasion.

In our laboratories we use high-tech equipment to carry out thorough controls of all raw materials and all quality controls of the manufactured product which are necessary to certify them.

Which SILCODISC-PE should I choose?

In order to determine the most suitable type of mould for the part you want to manufacture, you have to take into account different factors such as the type of material to be used, the shape of the part, the degree of flexibility needed to remove the part from the mould, etc.

To do this, visit our product SILCODISC-PE where you will find the list of all available types and can easily determine which one is the most suitable.

Advice: To manufacture parts that are difficult to remove from the mould, choose moulds with lower hardness, as they are more flexible and have excellent resistance to breakage.


Hands, workbenches and utensils must be kept at the highest level of cleanliness. Original parts must be free of grease or varnish.

Due to the low viscosity of the mould before vulcanization, the parts are placed in the usual way and very easily.


Temperature:    170 – 180ºC

Pressure:            10 kgs/cm2 minimum. See our pressure table
Time:                   5 minutes for every 2 mm. of mould thickness.

EXAMPLE: A 10+10 mm mould. = 20 mm. thick needs 50 minutes of vulcanization at the indicated temperature.

“Our SILCODISC moulds do not expire, although we recommend their use within 2 years”

Our Applications Laboratory is at your disposal for any consultation on the subject.

To make the mould correctly we have all kind of ACCESSORIES such as centring points, release agents, gouges of different sizes, tear-off silicone, etc, which will be very useful to you. Moreover, if you have doubts about how to use the product, either when making the mould or when performing the process, or you simply want to improve your technique, Coniex offers COURSES ON SPIN CASTING in its facilities


All our products always come with the corresponding safety data sheet (SDS). For proper waste management, please refer to section 13 of this MSDS.

To obtain the best results when manufacturing PEWTER parts, we recommend using our PEWTER alloy, specially designed for these moulds. See our section  PEWTER ALLOYS
