The process of production is carried out by
press-formings and extrusion /pulling out/ for profiles.
The materials used are in accordance with clients’ preferences in the range
of artificial and natural elastomers /rubber/, industrial silicones and silicone-based
mixtures for the food-and-beverage industry.
The tools and instruments are designed in The
TRELP – GEORGIEVI & Co. at clients' specification, an existing detail, the
application and the working parameters of a product or a drawing, sketch and/or
scheme of the final product. The press-formings /matrices/ are made by the method
of cold work of metal carried out by our contractual partners. There is a possibility
for production by a client’s tools and instruments.
We are present to You part of our possibly
