Hot-top Casting Transition Plate
Products Description
Hot-top Casting Transition Plate
About the Product
Shandong Jinyi New Material Co., Ltd. specializes in the R&D and production of hot-top casting series products for molten aluminum. As a core component of the hot-top casting flow control system, the transition plate connects the hat plate, distribution plate, and thimble, ensuring stable and low-turbulence flow of molten aluminum. It is compatible with Wagstaff air slip casting units and widely used in high-end aluminum casting fields such as new energy vehicles and aerospace.
Core Materials & Performance
- Sigma Material: Suitable for medium-to-high frequency casting, featuring corrosion resistance, high dimensional accuracy, smooth surface, and thermal shock resistance without cracking;
- N17 Material: Designed for high-load and long-cycle scenarios, with high mechanical strength and wear resistance, suitable for high-purity aluminum casting (e.g., 6xxx/7xxx series alloys);
- Both materials are compatible with BN coating, which reduces adhesion, enables easy cleaning, and extends service life.

Installation Instructions
- Select transition plates and matching components of corresponding specifications according to alloy diameter;
- Install components on the upper and lower platforms respectively. Ensure surfaces are smooth, undamaged, and seamless; seal and insulate the sides and bottom with ceramic fiber for heat preservation;
- After installation, preheat the platform to 260-350℃ (to remove adsorbed crystal water). Direct flame heating on the lining is prohibited.
