A ceramic fiber launder is used to guide molten aluminum between process stages in an aluminum foundry. When a standard design does not match the production line, a customized launder may be required to fit the equipment layout and metal-transfer route.
To evaluate a customized launder request, a supplier needs more than the required length. The shape, connection points, installation space, operating conditions, and maintenance requirements can all affect the proposed design.
This guide explains what information to prepare before requesting a quotation for a customized ceramic fiber launder.

Describe the Launder’s Application
Begin by explaining where the launder will be used and what it needs to do.
For example, is it intended to guide molten aluminum from a melting or holding furnace to a casting machine, or to connect two stages of an existing production line?
Describe the transfer route and the equipment at both ends. If the launder replaces an existing component, explain whether the current design works well or whether you want to address a specific problem.
Useful details include:
- The source and destination of the molten aluminum
- The equipment connected to the launder
- The required direction of metal flow
- Any known limitations in the existing installation
This information helps establish the design requirements before dimensions are finalized.
Provide Dimensions and a Drawing
Dimensions are essential when a launder must fit existing equipment.
If possible, provide a drawing showing:
- Overall length
- Internal width and depth
- Cross-sectional shape
- Inlet and outlet dimensions
- Connection points and support locations
- Available installation clearance
If you do not have a formal drawing, send clear photographs and a sketch with measured dimensions.
For a replacement project, photographs of the existing launder from several angles can help explain its shape. However, photographs should supplement measurements rather than replace them.
If the layout is still being designed, provide the available installation space and the intended route between the connected pieces of equipment.
Confirm the Required Shape and Configuration
Customized launders may need different geometries depending on the equipment layout.
When discussing the design, clarify whether you need a straight section, a particular cross-sectional profile, a spout, or other application-specific features.
The SF-Foundry product page describes customized ceramic fiber launders in different geometries, including U-shaped and V-shaped configurations, as well as designs with spouts and different lengths.
Do not assume that every shape or connection is available for every application. Provide a drawing or describe the required configuration so the supplier can confirm feasibility.
Explain the Operating Conditions
The operating conditions must be confirmed before the material and design are finalized.
Provide the information available about:
- Aluminum alloy or alloy family
- Normal operating temperature
- Frequency and duration of use
- Metal-transfer process
- Whether alloy changes occur during production
- Existing surface-treatment or coating requirements
If your foundry frequently changes alloys, mention this when requesting a quotation. The supplier can then clarify whether the proposed material and surface treatment are appropriate for the intended process.
Temperature limits and coating compatibility should be checked against the technical specifications of the exact product. Do not assume that a general ceramic-fiber description establishes suitability for every operating condition.
Identify Installation and Support Requirements
A customized launder must fit the actual installation, not just the nominal dimensions.
Explain how it will be supported and whether it needs to connect to existing furnace outlets, casting equipment, or other sections of the transfer system.
Where possible, provide:
- Support and mounting details
- Connection dimensions
- The position of nearby equipment
- Space available for installation and removal
- Any restrictions on lifting or maintenance access
If the current launder is difficult to install or remove, describe the issue. It may help the supplier identify the design details that require closer review.
Discuss Maintenance and Replacement Needs
Maintenance requirements should be considered before ordering a customized launder.
If you are replacing an existing unit, explain what prompted the replacement. For example, you may have observed surface damage, cracking, coating deterioration, or difficulty during cleaning.
Share any available maintenance records and the current operating procedure. These details help the supplier understand the service conditions, although the cause of a failure should not be assumed without inspection.
Ask for the applicable instructions on handling, cleaning, inspection, coating maintenance, and repair. Follow the manufacturer’s guidance for the specific product supplied.
Prepare the Information Needed for a Quotation
Use this checklist to prepare your inquiry.
| Item | Information to provide |
|---|---|
| Application | Where the launder transfers molten aluminum |
| Dimensions | Length, width, depth, and inlet/outlet measurements |
| Configuration | Required shape, spout, and connection details |
| Operating conditions | Alloy, temperature, and usage pattern |
| Installation | Support arrangement and available space |
| Existing equipment | Photos, drawings, or current launder details |
| Maintenance history | Known damage or recurring issues, if applicable |
| Quantity | Required number of units |
| Delivery | Destination and required schedule |
You do not need to have every answer before making an initial inquiry. Send the information available and clearly identify any measurements or technical details that still need confirmation.

Request a Customized Ceramic Fiber Launder Quote
SF-Foundry offers customized ceramic fiber launders for aluminum casting applications. To help us review your requirements, provide the application, available dimensions, configuration, operating conditions, and estimated quantity.
Drawings and photographs of the existing equipment are especially useful when the launder must fit a particular production line.
If you are replacing an existing launder, explain the reason for replacement and identify any requirements that differ from the current design. Our team can then review the information and clarify what additional details are needed.

Frequently Asked Questions
1. Can a ceramic fiber launder be customized to fit existing equipment?
Customized designs may be possible depending on the configuration and manufacturing requirements. Provide the dimensions, drawings, and equipment interface details so the supplier can assess feasibility.
2. What if I do not have a technical drawing?
Start with measured dimensions, clear photographs, and a sketch showing the inlet, outlet, and installation arrangement. The supplier can advise whether further measurements are needed.
3. Should I provide the operating temperature?
Yes. Provide the normal operating temperature and any relevant operating conditions you know. The permitted temperature range must be confirmed against the technical specifications of the proposed product.
4. What if the existing launder has developed cracks or surface damage?
Describe the location and extent of the damage, the operating conditions, and any maintenance history. Photographs may help with the initial review, but the cause should be confirmed rather than assumed.
5. Can I request a quotation before the design is finalized?
Yes. You can begin with the application, preliminary dimensions, required configuration, and estimated quantity. Final pricing and production feasibility depend on the confirmed design and specifications.
