Starter set mould making with silicone

You always wanted to make your own moulds with silicone,
but don't know exactly what you need and how to do it?

Here is the starter kit for this and it contains everything you need to get started straight away:

TFC silicone rubber type 3 HB tin cast heat resistant 1:1 500 g
Aluminium mould making frame with base plate 20 x 20 cm
250 g modelling clay non-hardening sulphur-free
TFC Trennvaseline Silicone - Silicone 50 ml
Technical book Working with silicone detailed introduction


TFC Silicone Rubber Type 3 Tin Casting heat-resistant 1:1
Content: 500 g

Addition-curing 2-component silicone rubber that vulcanises at room temperature (RTV).

The silicone is supplied in high-quality plastic squeeze bottles with a dosing cap.
This makes removal very easy and clean.
The exact dosing succeeds effortlessly, as you also know it, for example, from comparable food packaging
and is a clear improvement on the otherwise usual tinplate cans or wide-neck bottles.

Properties and application:
- easy processing
- trouble-free mixing of components 1:1 by weight
- very good flowability, mixture is easy to pour
- cross-linking to form resistant, rubber-elastic vulcanizate without heat of reaction
- short-term temperature resistant up to 450 degrees Celsius
- high tensile strength and high flexibility
- very high detail reproduction
- For the production of moulds for pouring with low-melting metals (tin, lead)

Aluminium moulding frame with base plate 20 x 20 cm
Variable moulding frame made of aluminium, consisting of:

4 aluminium angle plates, dimensions 100 mm x 200 mm x 50 mm
1 aluminium base plate, dimensions 200 mm x 200 mm

The 4 angle plates can be variably shifted against each other,
so that a variable casting box can be adapted exactly to the model,
to obtain an optimal shape, i.e. only the amount really needed.

Plastiline modelling clay non-hardening orange, 250 g
Colour: orange
Content: 250 g

Made on a wax basis, remains soft, modelling clay.
Easy to knead, does not stain or smear. Suitable for children from 3 years.


TFC separating vaseline
Silicone mould separating vaseline is applied thinly to the already hardened silicone mould during mould making and the newly mixed silicone for the second half of the mould is poured onto it. This prevents the two halves of the mould from sticking together. The release vaseline is free of harmful substances!
