The casting launder has an ultra-long life liner, it uses a new high-silicon molten material molding technology. Heated launders are self-preheating, aluminum transportation troughs. AdTech troughs have the capability to transport molten aluminum while reducing or eliminating temperature loss. The aluminium transportation troughs have strong corrosion resistance, non-stick aluminum, and no pollution to aluminum liquid. Production technology of aluminum products that can meet the requirements of high added value and high technical performance. AdTech launder is installed between the furnace and the casting machine. And molten aluminum launder has dual functions: conveying and thermal insulation. The ceramic launder adopts a wet vacuum forming process. The strength is higher than fiber blankets and vacuum forming felts, and it is suitable for high-temperature fields.
