The processing technology is “cast moulding”, i.e. low compression moulding. A prototype in full scale is manufactured on the grounds of a 3D design, being then used for the making of a mould.
The mould, in compound material, can be produced following the traditional processing method (positive and negative) or with inserts driven by hydraulic rams.
Therefore CRISTALPLANT© moulding may be compared with an injection moulding process.
An injection point is provided, from which the material enters, pouring into the mould.
Once the mould is filled, the material catalyzes and gets solid. Unlike the traditional injection method for plastics, here material thickness may increase even remarkably. There is no evidence of shrinkages by the inner ribs or bead.
The only thing to be wary of is a huge mass of material, which may cause a bad catalysis in the area in hand (45-50 mm max sections are recommended). It is possible to get limited undercuts or back drafts in the piece, if an inclined mould is provided; obviously, each case shall be analyzed deeply and separately to check the way for a right extraction of the piece out of the mould.
Being a “solid-surface” material, CRISTALPLANT© can be cut and glued on. This feature gives way to several customized items, such as custom-tailored cuts of moulded products, with no limit to design as for size or shape. Indeed, this feature lets designers create their object as moulded in 2 or more parts that can be then stuck one another and finished as one single piece; naturally, the more are the parts making the product the more expensive the sticking process will be.
As for bath decoration items, it is important to design the basin in one single piece, as it is the space containing water and undergoing heavy thermal shocks; any cut or joint shall be made on the outer side, then. The weld joints are always performed during the post-moulding stage and using the same material, thus creating one single piece with no visible sticking on it.
CRISTALPLANT© finishing process is completed by using special Scotch-Brite© glass-papers and wire wools, thus creating a “velvety” and natural stone-like finish.
Moreover, CRISTALPLANT© could be painted on the outer side, the one not in contact with water, using a soft-touch paint that is available in more than 700 different colours.

CARE AND MAINTENANCE
Chipping restoration on Skins, Shower trays, Bathtubs
Burns and persistent stains restoration on table
CRISTALPLANT© requires an easy and quick daily care. It is enough to clea CRISTALPLANT© using soap and water or common detergents to remove most of the dirt and stains that may be deposited on the surface. It is particularly recommended to rinse the surface well and to use gel or abrasive detergents with abrasive sponges like “Scotch Brite©” as in attached sample; doing that way, the original matt finish, distinguishing feature of CRISTALPLANT©, will keep untouched.
HOW TO PREVENT FROM DAMAGES
The surface is generally strongly resistant against stains and spots; nonetheless aggressive chemical products, such as acetone, trichloroethylene, strong acids or bases are not recommended. After long contact periods, several substances like ink, cosmetics and dyes, may leave colouring agents on CRISTALPLANT©, surface; the same may occur as for lit cigarettes; but all of that can be removed following the recommendations reported below.
HOW TO REMOVE PERSISTENT STAINS, SCRATCHES AND BURNING RINGS
CRISTALPLANT© is an homogeneous material in all its thickness and depth, thus it can restore its surface original beauty from aggressive agents, such as scratches, burning rings from cigarettes and persistent stains, simply by following these instructions: as for small damages, use an abrasive Scotch Brite© (3M trademark) sponge and a common abrasive detergent to restore the surface. Rub superficially the damaged part down. If the defect is still visible, rub again using very fine glass-paper.
Powder or cream detergents like CIF©, VIM© or similar, containing micro-granules with abrasive action on the surface. Methylated spirits may be used only being wary of rinsing well the surface.
NON TO USE:
Solvent agents like acetone or trichloroethylene, as well as other aggressive chemical substances like strong acids (muriatic acid…) or bases (caustic soda…). Detergents for industrial use or others of unknown aggressive action: in this case a test on a spot not in view should be done before application. Very aggressive substance generally used to clear sink pipes. Solvents used in the painting industry.
REPAIRING SERIOUS DAMAGE WITH
THE MAINTENANCE KIT (FOR TECHNICIANS)
2) Using a stainless steel spatula or putty knife, mix accurately the filler/putty provided with the catalyst, up to a complete dispersion of the liquid substance. N.B. Use thoroughly both components; in case of wrong proportions of catalyst, the risk is to get a yellow colour finish (too much catalyst) or not enough hardening (not enough catalyst).
3) Apply the filler/putty on the damaged part and close around it. The filler/putty should be applied a few at a time inside the flaw, preventing air from going out. The result to get is a putty surface in relief, on the damaged part and close around it.
4) Let the filler/putty harden for at least 12 hours at an ambient temperature, that should be at minimum 15°C to get good results. The use of a warm air generator (hairdryer) would help speed catalysis activation and get a faster hardening process. In this case, after complete catalysis of the filler/putty, 4-5 hours are enough to remove it.
5) The filler/putty is to be removed by 220 grain glass-paper. In case of big excess of applied filler/putty, it is recommended to use a rubbing machine, priming with a 120 grain glass-paper and finishing with a 220 grain glass-paper. The surface should be rubbed down and smoothed evenly, including also the parts around the defect in order to eliminate any non-homogeneous part, especially sinking or hollow effect.
6) After filler/putty removal, eliminate the consequent dust and start cleansing using common detergents and the Scotch Brite® sponge included in the maintenance kit.
