Products Description
Shandong Jinyi Hot-top Casting Graphite Ring
1. Product Overview
Shandong Jinyi New Material Co., Ltd. specializes in R&D and production of high-performance components for molten aluminum hot-top casting. The graphite ring, as a core sealing and wear-resistant part in hot-top casting systems, collaborates with transition plates, distribution plates, and casting thimbles to achieve leak-free molten aluminum flow. It is fully compatible with Wagstaff air slip casting units and widely applied in high-end fields such as new energy vehicle aluminum parts, aerospace components, and precision aluminum casting.

7. Installation Instructions
- Select the graphite ring size matching the alloy diameter and hot-top casting equipment model.
- Install the graphite ring between the transition plate/thimble and the casting platform; ensure the surface is smooth, undamaged, and seamless with adjacent components. Seal edges with ceramic fiber material for thermal insulation.
- After installation, preheat the casting platform uniformly to 260℃-350℃ (to remove adsorbed crystal water); direct flame heating on the graphite ring itself is prohibited.
