Hantai Fire Sleeve Application – High-Temperature Hose Protection for Large Die-Casting Islands

The Critical Role of Die-Casting Islands

As an integrated production system, the die-casting island injects molten metal into molds to form precision castings. ​Fire Sleeve-protected hydraulic systems enable continuous operation under extreme conditions, particularly crucial for NEV megacastings requiring 9,000+ ton clamping force.

High-Temperature Risks in Fluid Pipelines

Key pipelines within die-casting islands require ​Fire Sleeve thermal barriers to combat:

• Surface temperatures exceeding 800°C
• Instantaneous spikes to 1,650°C from molten aluminum
• Hydraulic hose hardening (70% hardness increase at 260°C/500h)
