A major overhaul and modernization of the blow head mechanism has been carried out. The main pneumatic cylinder body was reworked across all mating surfaces, including channel cleaning and replacement of valves and seals.
The new upgraded guides are equipped with more durable seals made of a specialized polymer material.
New pistons with a swivel groove were designed and manufactured, allowing for reduced clearances and increased service life.
The new rod and swivel-groove piston are made of heat-treated and ground high-alloy steel. The surface roughness of the mating parts does not exceed Ra 0.8

As a result of the overhaul and modernization, the following was achieved:
The service life of the unit has been extended without compromising quality;
Operating pressure has been reduced to 0.45 bar;
Operational speed and precision have been increased.
The upgraded funnel mechanism now demonstrates more stable performance across the glass-forming sections. The reverse engineering performed has enabled the preparation of design documentation, allowing for the rapid production of new funnel mechanisms as required.
