Glass Industry Forgings — Furnace Structural Components, IS Machine Blank/Blow Mould Arms, Forming Rolls
Shivam Forge manufactures heat-resistant and structural forgings for float glass, container glass, and fibreglass manufacturing equipment — furnace structural bracket and tie rod forgings, IS (individual section) machine mould-holder arm forgings, and glass forming roll shaft forgings — in heat-resistant alloy steel and high-temperature nickel alloys for furnace-adjacent applications.

Glass manufacturing — whether float glass production for architectural and automotive glazing, container glass (bottles and jars), or fibreglass — centres on continuous-operation furnaces that melt raw batch materials at temperatures exceeding 1500°C, running non-stop for years between planned rebuilds (a float glass furnace campaign commonly runs 12-15 years continuously). The mechanical and structural equipment operating around and downstream of these furnaces — furnace superstructure tie rods and buckstays that contain the refractory structure's thermal expansion forces, IS (individual section) machine mould-holder arms that open and close glass container moulds thousands of times per shift, and forming roll shafts that shape molten glass into sheet or fibre form — must reliably perform under combinations of elevated ambient temperature, mechanical cyclic loading, and in some locations, direct radiant heat exposure from the furnace itself, driving material selection toward heat-resistant alloy steels and, for the most furnace-proximate components, nickel-based high-temperature alloys.
Forged tie rod and buckstay structural components that contain the outward thermal expansion forces of the furnace's refractory brick structure, engineered in heat-resistant alloy steel for reliable performance across the furnace's multi-year continuous operating campaign.
Forged mould-holder arm and linkage components for individual section (IS) machines used in container glass manufacturing, where mechanisms open and close glass container moulds many thousands of times per production shift — driving fatigue design requirements comparable to other high-cycle mechanical equipment.
Forged shaft components for glass forming rolls used in float glass and sheet glass production, operating in elevated-temperature environments adjacent to the glass ribbon as it cools and is shaped through the forming process.
Structural and mechanical forgings for batch charging equipment that feeds raw glass-making materials into the furnace, operating in the elevated-temperature zone near the furnace charging end.
Forged components in nickel-based high-temperature alloys for the most furnace-proximate mechanical equipment where heat-resistant alloy steel's temperature capability is insufficient, similar to the high-temperature alloy expertise we apply for power generation and process industry customers.
Material grade selection for sustained elevated-temperature service, balancing heat resistance, cost, and mechanical property retention at operating temperature for furnace-adjacent structural and mechanical components.
Fatigue design margins calibrated to the thousands-per-shift cycling IS machine mould-holder mechanisms experience, reflecting the same high-cycle fatigue engineering discipline applied across our other high-duty-cycle mechanical equipment forging product lines.
Component reliability engineered for glass furnaces' multi-year continuous operating campaigns, where unplanned component failure requiring furnace shutdown carries substantial cost given the difficulty and expense of restarting a glass furnace outside planned rebuild schedules.
Material test certificates confirming chemistry and mechanical properties per EN 10204 3.1, issued as standard for every batch supplied to glass manufacturing equipment customers.
Glass manufacturing occupies a distinctive position among industrial applications for forged mechanical and structural components: it combines the sustained, multi-year continuous operation characteristic of heavy process industries (a float glass furnace campaign commonly runs 12-15 years without shutdown, comparable to or exceeding many petrochemical plant operating campaigns) with localized but severe temperature extremes near the furnace itself, and — in container glass manufacturing specifically — genuinely high-cycle mechanical duty in the IS machine forming equipment that shapes molten glass gobs into finished bottles and jars at rates of many cycles per minute across continuous production shifts.
The structural engineering challenge of glass furnace construction centres on managing the enormous thermal expansion forces a 1500°C+ refractory structure generates as it heats from cold startup to operating temperature and remains there for years — tie rods and buckstays, the structural steel members that contain these expansion forces and keep the furnace's brick superstructure dimensionally stable, must be manufactured from materials that retain adequate mechanical strength at the elevated ambient temperatures common in the furnace's immediate vicinity, a materials selection challenge with clear parallels to power generation and process industry high-temperature equipment engineering, even though glass manufacturing itself sits outside those more commonly discussed industrial sectors.
Container glass manufacturing's IS (individual section) machines represent one of the higher-cycle-count mechanical systems in general industrial equipment — a busy IS machine section can complete a full mould open-close cycle multiple times per minute, translating into extraordinarily high annual cycle counts for the mould-holder arm and linkage mechanisms involved, a duty cycle intensity that places these components in a similar fatigue engineering category to the high-cycle automotive and industrial equipment components that dominate much of precision forging demand, despite glass manufacturing's relatively lower profile as an industrial sector.

Glass furnaces operate continuously at temperatures exceeding 1500°C for campaigns commonly lasting 12-15 years without shutdown. Structural components like tie rods and buckstays, positioned to contain the furnace's thermal expansion forces, must reliably perform under sustained elevated temperature exposure across this entire continuous operating period.
An IS (individual section) machine is the core forming equipment in container glass manufacturing, with mould-holder mechanisms that open and close glass container moulds many thousands of times per production shift — this high-cycle mechanical operation requires forged components with fatigue design margins comparable to other high-duty-cycle industrial equipment.
Yes. Forged shaft components for glass forming rolls used in float glass and sheet glass production, engineered for the elevated-temperature environment adjacent to the glass ribbon during the forming process.
Yes, for applications where heat-resistant alloy steel's temperature capability is insufficient, we supply nickel-based high-temperature alloy forgings, drawing on the same high-temperature alloy expertise we apply for power generation and process industry customers.
Glass furnaces run continuously for years between planned rebuilds, and unplanned component failure requiring an unscheduled furnace shutdown carries substantial cost and operational disruption given the difficulty and expense of restarting a glass furnace outside its planned rebuild schedule.
