RHODORSIL RTV2's enable moulds to be made for all types of applications using a few basic principles.
In spite of the multiple variants that are possible, basic processes exist which are described below.

The choice of the moulding process is made taking into account the following parameters;

- time constraints
- material constraints
- size, shape and position of the model (horizontal, vertical, overhead)

MODEL FEATURES		MOULDING TECHNIQUE	APPLICATION TECHNIQUE	ADVANTAGES	DISADVANTAGES
	Flat back, few or no undercuts	One Part Block Moulding	Casting	- Quick,easy to perform - Self supporting moulds - Low cost to produce	- Limited to relatively simple shapes that do not vary much in cross section - Significant material consumption
	Fully structured, few or no undercuts	Two Part Block Moulding	Casting
	Flat back, accentuated undercuts	One Part Skin Moulding	Casting	- Thin section membranes - Economic in RTV - Large degree of flexibility favoring difficult moulding operations - Availability of tooling enabling the production of membranes	- Longer to implement than the block moulding method - Higher cost of production
	Fully structured, accentuated undercuts	Two Part Skin Moulding	Casting
	Little or accentuated undercuts, Voluminous model on base, On-site reproduction	One Side Impression Moulding (Brush Moulding)	Brush, Spatula, Spraying	- Possibility of taking imprints on site - Possibility of taking vertical, overhanging imprints - Adapted to large size moulding - Economic in RTV	- Membrane is not interchangeable between backing moulds - Longer to implement than the block moulding method - Difficult to perform
	Little or accentuated undercuts, Fully structured, Voluminous model that is not easy or that can't be moved	Two Part Impression Moulding (Brush Moulding)	Brush, Spatula, Spraying
