Our heritage is refractory manufacture and since the founding of the company we have only ever manufactured refractories for the glass industry. This is a tradition that continues to this day. We specialise particularly in bonded refractory materials for the feeder, forehearth and distributor.
Feeder expendables are the refractory parts used in the gob forming process. They are ‘expendable’ because they are changed frequently during the life of the furnace depending upon the requirements of the forming operation. As the final link between the melting and the forming processes however their properties have immense influence on the success or failure of the entire forming operation. >
PSR has a long history in the manufacture of blocks and channels for the glass melting furnace and their experience in cutting and grinding large refractory shapes enables them to meet tight dimensional tolerances. All PSR’s channels and glass contact blocks are diamond polished on specially designed sequential cutting and grinding machines. >
We design, manufacture and supply the complete refractory assembly for our System 5oo forehearths. In addition to fulfilling the needs of our own systems, we can also supply the complete refractory substructure and superstructure for most other designs of forehearth, and can also offer the services of our team of designers and engineers to upgrade and improve existing forehearth systems. >
