As a long established global supplier, we offer a complete range of precious metal solutions to the glass industry. From platinum and iridium fabrications, through to thermocouples and our proprietary ACTTM coatings, we can positively influence both the process efficiency and the glass quality. As well as exceptional products, we offer unparalleled technical expertise, ensuring you achieve your goals in the most demanding of industries. And we tailor our recommendations based on the technology that best meets our customer needs, helping to minimise costs and maximise benefits.
Our platinum group metal (pgm) products are inert in contact with molten glass, providing unequalled resistance to corrosion during glass melting and forming. They offer financial benefits through:
- Increased output
- Lower downtime
- Extended campaign life
- Ceramic shape retention
- Reduced glass defects through reduced erosion of ceramic parts by the molten glass
- Producing more conforming products and less re-working.
We offer full precious metal recovery, with typical returns of over 95% for ACT coatings and 98% for fabrications and linings.
Advanced coating technology
Ideal for long runs and limited thermal cycling, our ACT coatings protect ceramics through the thin coating (200-500 microns) of platinum or 10% rhodium/platinum on the surface. They can be used with any type of glass, including the most corrosive, and provide 100% shape retention for the lifetime of the coating.
Thermocouples and assemblies
As a market leader in pgm thermocouples, our wires and assemblies are renowned for accuracy and reliability. We supply type R, S and B thermocouple wire as well as other precious metal combinations. Our thermocouple assemblies are proven to last the full furnace campaign, withstanding the high temperature and demanding conditions of glass manufacturing. We also offer full technical support, including advice on safeguarding thermocouple performance and minimising drift.
Fabrications and linings
Our self-supported fabrications and linings withstand thermal cycling, ceramic cracking and exchange of contacting parts. We make welded sheets of platinum/rhodium alloys, dispersing them with zirconia grain stabilised particles to increase the mechanical strength and durability for more demanding applications. Alternatively, our iridium products can withstand higher temperatures, have a higher mechanical strength and provide opportunities for new glass applications.
