All About Vinamold
The Material
Vinyl rubber is a re-usable self-releasing rubber supplied in solid blocks. It is extremely versatile and can be
used to produce moulds for a wide range of casting applications such as polyesters, epoxies, plaster and
concrete. The material requires heating to approx. 160ºC before being poured over formers or originals to
produce moulds. Because vinamold is intended as a craft material, little equipment or expertise is required.
Vinamold is melted by heating, then pouring over the article to be copied and allowed to cool. Unlike some
other flexible mould materials vinamold is thermoplastic, and re-melts on re-heating. Worn or obsolete
moulds may therefore be cleaned and re-used many times. Generally, the lubricants incorporated in
vinamold are sufficient, however additional suitable release agents, if used, should first be tested to ensure
that no surface damage is likely to occur. The limitation of Vinamold is that it can only be used in
conjunction with utensils, materials and originals that can sustain prolonged heat. Various grades of Vinamold are available and they are distinguished by colour - red is quite supple and
suitable for small or detailed castings, whereas yellow is quite firm and ideal for heavier items such as
concrete.
There are occasions when the topology of the original would make it impracticable to de-mould the vinamold in one piece; however, by slicing through the set vinamold (or even carefully tearing it where a sharp blade is not appropriate) -
then matching up and strapping the sections together, it is possible to make moulds and produce castings
from the most complicated originals; seam lines in the finishing castings can be easily be smoothed over
later. An alternative is to mould and cast projections, extended limbs, etc., separately - which makes it easier to introduce reinforcement (dowels or wire) into slender areas or vulnerable points.
Working With Vinamold
The more care and control exercised in melting vinamold the more times the material can be re-used.
Thermostatically controlled melting equipment is available but a heavy pan used on a carefully
controlled hob or in a suitable oven, etc is the usual method. For small projects (say, less than 1kg of
material) the rubber can be melted in a microwave on a low setting in a glass or ceramic bowl, however constant observation is
required throughout to ensure no overheating - the material only needs to be brought to a liquid state, and
no fumes or discolouration should arise, as this is an indication of decomposition. In all cases, the rubber
blocks that the material arrives as should be cut up into smaller more manageable pieces of between 20 -
30mm width, etc.
If a suitable vessel or pan cannot found to make the mould box or container, use clay, wood or other
suitable medium to make a retaining wall on a baseboard, etc, remembering to seal all the gaps, etc. Pour
the molten vinamold slowly and steadily (at the base of the original on profiled objects) to the required
depth, ensuring a minimum cover 20mm. To avoid air being trapped it may be necessary to manoeuvre the
whole assembly so that the liquid can run into all the detail, so an assistant should be available to help.
Leave the finished mould at least 8 hours before attempting to release it. On intricate or heavily profiled - or
very smooth surfaces - this may take quite some time, and should be a process of gentle manipulation
rather than resorting to any tools which might cut or tear the rubber.
Small faults, due to air bubbles, tears, or deficiencies in the original, can be corrected by carefully touching
up with a hot blade. Small pieces of vinamold can be fused into the mould surface to take up cavities.
Preparation Of Originals
N.B. If an original is rare, valuable, or delicate take extra care in sealing and pre-warming. If in doubt as to
the possible effect of sealing materials or the effect of heat, try a few experiments on similar materials or
objects that are expendable. Porous Dry Clay or Lightweight Plasters: seal surface with PVA sealer.
Wood: experiment with surface sealer. Epoxy resin may be used as a sealer to prevent bubble formation in
vinamold due to air and moisture from the wood. Concrete or Stone: Fill pores by soaking with water.
Allow surface to dry superficially prior to pouring vinamold. Metal: No sealing is necessary. A thin film of
mineral or vegetable oil will facilitate removal from the vinamold. Porcelain and glass: Carefully prewarm
to prevent breakage when vinamold is poured over the originals. Clay: No preparation needed. Fibreglass/
Resins: Pre-heat for 30-60 minutes to ensure full cure and freedom from volatiles.
Safety Notes
During the melting stage, avoid breathing fumes at all times. The fumes associated with the melting of
vinamold are caused by the volatility of the plasticising compounds used in the material. None of the
plasticising compounds are considered toxic, so the vapours produced during the heating of vinamold are a
nuisance rather than a hazard. Nevertheless, for the comfort of the user, and to avoid any possible irritation
of the respiratory tract, we would always recommend adequate ventilation and extraction as necessary in
the area where vinamold is being heated, to remove fumes. If melted at the correct temperature in a
ventilated room, it should hardly be possible to smell vinamold. However, serious overheating will lead to
fumes and decomposition, and if prolonged can cause respiratory irritation, whereby possible damage to
health cannot be excluded. Overheating is indicated when the material fumes heavily and changes colour to
dark brown or black; in which case remove from the heat and the working area. Discard burnt material. New
vinamold should not be mixed with burned or very old vinamold. Due precautions must be taken against
possible fire risk. Keep vinamold away from flames and electric elements, particularly when vinamolds are
in their molten state. If vinamold catches fire, dry sand should be used. Drenching with water is best
avoided, since it turns to steam and may be hazardous in confined areas.
