WHAT IS VINAMOLD?
Vinamold mould making compound can be used in the creation of a range of moulds from the simple to complex: available in three colours - representing 3 hardnesses, each of which is ideal for a variety of casting materials. It Is a highly plasticised PVC compound giving both a flexible and durable product that is non-toxic and meets the safety requirements for children's' toys.

WHY USE VINAMOLD?
Cost Benefits: Reusable (by melting down discarded moulds). The same mould can be used for numerous castings.
Detail: Exceptional detail reproduction.
Flexibility: Material retains flexibility whilst remaining tough.
Multiple choice: Choice of grades for different applications.
Material properties: Built in release agent.
Safety: Non-toxic provided the usage instructions are followed.

HOW TO USE VINAMOLD
To use Vinamold you require a melting pot. These can vary in capacity up to 250 litres. A case then needs to
be constructed and heated Vinamold poured on the master. Once cool, the Vinamold mould is ready for use.
For further information on the production of moulds, refer to the detailed instructions.

WHERE TO USE VINAMOLD
Vinamold has many applications in Construction, Interior Decoration,
Ornamental, Education and Souvenirs. Here are Just a few of the applications that
Vinamold has been used as a mould for:

Construction:
Prefabricated concrete panels, paving, decorative panels, ornaments, roof tiles.

Interior Decoration:
Ceiling and wall embellishments, coving, cornices, friezes decorative effects, furniture, mirror picture surrounds, false beams - wood, stone, brick simulation, doors, plaques, etc. suspended ceiling, acoustic and thermal Insulating tiles.

Souvenirs:
Replicas of antique Items, figurines, dolls heads, masks, historical replicas.

Arts and Crafts:
Sculpture replicas, fossil casts.

GELFLEX - Reusable Flexible Mould material
GELFEX is the registered name for certain remeltable compounds developed to form moulds of the required flexibility for casting Plaster of Paris (Gypsum) cement, thermo-setting resins, wax, etc.  The tensile strength of GELFLEX added to its flexibility allow objects with deep undercuts to be removed from the mould without damage.

GELFLEX compounds are reversible gels which retain their degree of flexibility throughout their working life, unlike some mould making materials.
Technological advances, particularly with heat stabilisers, have evolved a new generation of mould making compounds which are distinctly superior to the various grades previously used. These new grades, HARD (H.G. BLUE) and SOFT (S.G. NATURAL) satisfy a vast range of requirements and any intermediate degree of hardness or flexibility can be obtained by mixing the grades in the required proportions.

Characteristics of GELFLEX

Gelflex weight/Capacity/Volume equivalents
25 kgs  =  25 litres   =  5.5 gallons
1 kg     =  61 cu.inches  = 1000 cu.centimetres
1 gallon  =  4.6kgs     =   4.6 litres

Observation
The original object from which a mould is to be made is known as the MASTER, copies of the MASTER are known as REPLICAS.  Both of these are referred to in this brochure as MODELS whether they are cornices, figures or any other object. The product extracted from the MOULD is the CASTING.

Melting and pouring Gelflex
When GELFLEX has been melted at the specific temperature in a thermostatically controlled tank (see melting equipment) and run into a bucket, it must be left to allow the temperature to fall to the specified pouring temperature, measured with a thermometer, before pouring; this will also allow any air bubbles present to rise and disperse. Then the GELFLEX should be poured into the mould case at the lowest point; avoid pouring directly on the model.   Thermometers can be obtained from Proplastics Ltd.

If a thermostatically controlled pot is used (see Melting Equipment), the size will determine whether the GELFLEX temperature is reduced in the pot or in another vessel before pouring into the mould case.

For small melters  the GLEFLEX, which is supplied pre-cut into two-inch cubes, should be cut into one-inch cubes or smaller.  Load the melter to not more than one-third of its capacity and when the bottom of the load is melted, stir and mix, then replace the lid.  As the melting progresses ass the remainder of the cut pieces as required, stirring as necessary.  Before pouring ensure that the temperature is as specified.

Remelting Obsolete Moulds
Before cutting up old moulds for remelting they should be cleaned with hot soapy water or a weak solution of household detergent and water.  Paraffin, white spirit or organic solvents must not be used.
