Best performance for quick changes
Essential role of forehearth
Forehearths are vital for maintaining the quality and consistency of glass products. Any fluctuation in temperature or improper conditioning can lead to defects in the glass, such as bubbles, streaks, or irregularities, affecting the strength and visual defects of the final product. In summary, the glass forehearth plays an essential role in transitioning molten glass from the furnace to the forming stage, ensuring proper temperature control and homogeneity, which are key factors in producing high-quality glass products.
FCF system
- Each cooling zone equipped with highly efficient cooling system
(indirect, direct or combination of both). - Low system inertia to cooling parameters change, quick response of the forehearth.
- Typical width 36’’ and above.
- Typical pull 50-100 tpd.
Forced cooling
Combination of direct and indirect forced cooling gives a great tool for control the parameters of molten glass. Direct cooling ensures that the biggest temperature drops are possible between inlet to the forehearth and the gob. On the other hand indirect cooling allows to realize accurate and steady control of temperature. It is the key to achieving the most demanding parameters for glass homogenization. Both systems can operate separately if there are any limitations that restrict or exclude one of them.
