PD PreForm shapes are manufactured from alkaline earth silicate wools, which have high solubility insimulated body fluids and hence carry no hazard classification. These wools are blended with specially selected organic binders to give flexible insulating shapes with exceptional characteristics.

The PD-IsoMix 137 M55h material is a lightweight castable designed for orifice ring and spout insulation. It is a flowing castable, which allows the orifice ring or the spout refractory to be placed in the casing, and then the insulating material could be poured around it, filling even the smallest crevices. Setting time is around 1-2 hours on room temperature. In case of glass leakage, it stops the flow of the hot glass immediately, prevent the bigger damage.

P-D Refractories offers spouts with CR or fused cast insert. Used in conjunction with ZM30F spout bodies. Inserted spouts have greater life span, 150 - 250% depending on production conditions.

For pat lines – long run
Typically these lines manufacture beer and wine containers and account for approximately 10% of global installed IS Container machines.P-D Refractories offers multiple orifice rings with very dense corundum inserts made of AL95TB or isostatically pressed chromium oxide CR90-GE. By using these special inserts orifice ring the saving going to be significant due to the less job changes during a campaign.
The lifetime could be 50-200% more with these inserts, depending on the glass conditions and temperature.
