semi-finished production

is one of the few manufacturers producing its own semi- finished products. Glass tubes are shaped by skilled and experienced craftsmen in accordance with DIN standards, in specified outer diameters, lengths, and wall thicknesses. After quality control, semi-finished products are sent to high-temperature annealing furnaces to stabilize product properties. At the end of the process, products gain maximum mechanical strength and are not affected by sudden temperature changes. All ground joints used by are manufactured on automatic machines with excellent quality. For superior grinding quality, only diamond-tipped grinding tools are used. Ground joints are checked with highly precise measuring devices and consistently deliver accurate results. As a result of these processes, completely leak-proof, interchangeable ground joints with fully compatible structure are produced. Leak-tightness testing of ground joints is carried out using a special vacuum test device.

Technology enables any bending and welding process to produce durable glass components.

Glass tubes are formed to DIN-standard- compliant outer diameter, shape, and wall thickness by skilled and experienced craftsmen.

All ground joints used by INTERLAB are manufactured on automatic machines with excellent quality.

calibrated tube production

Production of tubes with different inner diameters and wall thicknesses requires high precision due to measurement sensitivity. manufactures tubes with inner and outer diameters and wall thicknesses within the same tolerance at every point. The production process uses a special vacuum drawing method. Glass is heated to high temperature and then gradually drawn with vacuum assistance. In the final stage, tubes are shaped on steel rods using vacuum drawing technology. Thus, tubes have uniform diameter along their entire length and a perfectly circular structure.

Tubes maintain the same inner diameter along their entire length and are shaped using vacuum drawing technology.

Glass tubes are first heated to the required temperature and then shaped on steel rods with precise diameters.
