Customized silicones for pads and rollers printing perfection
Manufacturers often need to print precise and durable markings or decorative patterns on their products. This is true for companies that make everyday consumer products such as toys and crockery, but also for those who produce high-precision parts for professional applications, such as car parts, medical imaging or precision tools. Printing can also involve edible products, such as food and medicines. This means that printing must be adapted to an almost endless number of surfaces and materials, from plastic to porcelain, via metals, films and sugar coatings, to name but a few.
Printing is done either with machines that use pads (stamping) or rollers (continuous print) and are made by specialist manufacturers who sell them as supplements or add-ons to printing machines. Some large-scale users, such as toy or porcelain manufacturers, can often produce or order customized pads directly, while tile-makers or film imaging labs often do the same for rollers.
Elkem Silicones has developed the Bluesil™ range of dedicated products to meet the printing needs of all these manufacturers and end-users. Formulations include RTV2, oils, foams and gels with specific and customizable features for high-performance printing that features excellent ink transfer and durability.
