Glass pipes of various dimensions are transformed through heating and blowing. With new technologies and development, we are achieving previously inconceivable product dimensions up to 500 mm in diameter, and the best surface which is very suitable for metallization or dyeing. Graphite molds are used for forming. The products are made of borosilicate glass, which is also used for laboratory purposes because it is extremely resistant to damage resulting from temperature fluctuations.
Sandblasting of glass
For illumination, there is often a need to diffuse the light source. For this purpose, the products are sandblasted at optional areas. Various inscriptions and logos can be sandblasted onto the products. The areas that should not be sandblasted are covered. We use an extremely fine electro-corundum that creates a top-notch surface.
Cutting of glass pipes
Cuts are performed with a diamond saw or by thermal shock. In preparation for thermal shock cutting, the glass pipes are scored with a diamond needle, and then heated with an extremely concentrated flame so that the glass breaks exactly along the cut-in line. The result is a sharp edge which is then ground or flame-treated.
Grinding of glass
After the glass is cut, we usually grind it to eliminate sharp edges or they are optionally finished. We drill holes or cut lines and grooves into the glass with diamond drills and special appliances.
