Custom-designed molten aluminum transfer and launder solutions manufactured according to your aluminum plant layout, process requirements and operating conditions.
Longzhiyi manufactures custom refractory-lined aluminum launder systems for aluminum foundries and aluminum processing plants. Based on the actual production line, furnace configuration, casting equipment, molten aluminum flow direction and installation space, we design and manufacture launder systems to match each customer's specific requirements.
Every aluminum plant has different equipment layouts, transfer distances and molten aluminum flow requirements. A standard launder may not provide the right dimensions, connections or flow path.
At Longzhiyi, we manufacture aluminum launders according to the actual conditions of your aluminum plant.
From straight launders to multi-section and customized transfer systems, we can adjust the structure, length, width, height, outlet direction and connection design according to your application.
Your production line determines the launder design — not the other way around.
The launder is designed with a high-temperature refractory lining suitable for molten aluminum transfer. The lining provides thermal protection and helps maintain the required operating conditions during aluminum transfer.
Launder dimensions can be customized according to your equipment layout, installation space and required molten aluminum flow path.
The internal channel geometry can be designed according to the required flow direction and transfer distance to support stable molten aluminum transfer.
A metal outer shell provides mechanical support and protection for the refractory lining, making the launder suitable for industrial production environments.
Inlet and outlet positions, connection sections, covers and other structural details can be customized to match upstream and downstream equipment.
Longzhiyi launders can be designed for different aluminum melting, holding, casting and molten metal treatment lines.
Longzhiyi does not simply supply a standard-size aluminum launder.
We first understand your actual production conditions and then manufacture the launder according to your requirements.
This makes the system easier to integrate into existing aluminum production lines.
We review your aluminum alloy, melting and casting process, equipment configuration and molten aluminum transfer requirements.
Customers can provide drawings, dimensions, photos or videos of the existing production line.
Our engineers develop the launder structure according to the required flow path, installation space and connection requirements.
The refractory and insulation structure is selected according to the operating temperature and application requirements.
The outer metal structure and internal refractory-lined construction are manufactured according to the approved design.
Dimensions, structure, lining condition and other key requirements are checked before shipment.
Longzhiyi provides the necessary product information and technical support to help customers integrate the launder into their production line.
The Longzhiyi Custom Refractory-Lined Aluminum Launder System can be used in various molten aluminum transfer applications, including:
Longzhiyi is a manufacturer specializing in aluminum melt handling equipment and customized molten aluminum solutions.
We manufacture launders according to the actual requirements of each aluminum plant rather than offering only fixed standard models.
Dimensions, flow channels, connections and structural components can be developed according to your production line.
Our custom launders can be designed to connect with existing furnaces, filtration equipment, degassing systems and casting machines.
Our team works with customers to understand the application before production, helping ensure that the final launder matches the intended installation and process.
To design a suitable launder system, you can send us:
1. Production line drawing
A CAD drawing or simple layout showing the furnace, filtration equipment and casting machine.
2. Existing launder dimensions
Length, width, height, channel dimensions and connection dimensions.
3. Photos or videos
Photos of the existing installation area can help us understand the actual working environment.
4. Molten aluminum flow requirements
Information about the required transfer capacity and flow direction.
5. Operating temperature
Typical molten aluminum operating temperature and process conditions.
6. Connection requirements
Inlet, outlet and connection dimensions of the related equipment.
Even if you do not have complete drawings, photos and basic dimensions are enough for an initial discussion.
Different aluminum plants require different launder designs.
Whether you need a straight aluminum launder, U-shaped launder, multi-section launder, insulated launder, refractory-lined launder or a complete customized molten aluminum transfer system, Longzhiyi can manufacture it according to your actual production conditions.
Send us your drawings, dimensions or plant photos. Our engineering team will review your requirements and develop a suitable aluminum launder solution for your production line.
