Project Overview
FH® Alloy received a project from an Italian customer who wanted to modify two existing tray products and develop two updated versions based on their current designs.

Instead of requesting a completely new product from scratch, the customer provided:

• the dimensions of the two existing products,
• the dimensions of the two new required versions,
• marked-up modification instructions,
• and a photo of the existing physical product.

Based on this information, FH® Alloy’s engineering team completed the redesign work and developed the final 3D product models for the new trays. After design confirmation, FH® Alloy proceeded with manufacturing, final quality inspection and delivery.
This project is a typical example of how FH® Alloy helps customers upgrade existing furnace tooling into improved, application-specific new products.

Customer Requirements
The Italian customer had two existing tray products and wanted both of them modified into new versions.
According to the customer’s request, the redesign scope included the following size changes:

The customer also provided a marked reference image showing the required structural modifications to the existing product.

The specified material for the new products was:
1.4852 heat-resistant alloy

Project Challenge
This project was not simple copy manufacturing.
The customer did not ask FH® Alloy to reproduce the current products exactly. Instead, the request was to modify the existing designs into new products according to the updated dimensional and structural requirements.

That means the engineering work needed to address several issues:
1. Converting Existing Products into Updated Versions
The redesign needed to preserve the useful design logic of the original trays while modifying key dimensions and structural sections.
2. Turning Marked-Up Instructions into Manufacturable Products
The customer provided modification guidance using an annotated reference image. FH® Alloy needed to interpret these marked areas and convert them into clear engineering geometry.
3. Ensuring the New Structure Was Suitable for Production
A redesign is not only about changing dimensions on paper. The final structure also needs to be practical for manufacturing, structurally reasonable and consistent with the material’s high-temperature application environment.
4. Managing Two Different Product Revisions in One Project
This case involved two separate redesigned tray models, each based on a different original product, requiring technical review and redesign of both versions.

FH® Alloy Engineering Solution
Based on the customer’s original products, dimensional change requests and marked-up reference, FH® Alloy completed the redesign and created the final 3D product models for the two new trays.

Redesigned Product 1: New UNI_2023003
The first redesigned product was based on the customer’s existing tray:
Existing size: 1000 × 588 × H50 mm
New size: 1000 × 588 × H30 mm
In this redesign, the overall length and width were maintained, while the structure height was modified from H50 to H30 according to the customer’s request.
This required FH® Alloy to optimize the tray geometry so that the new structure would match the revised dimensional requirement while still maintaining practical structural integrity.
The final result was a redesigned tray model suitable for the customer’s updated application needs.

Redesigned Product 2: New AD23060860-1
The second redesigned product was based on another existing tray:
Existing size: 800 × 800 × 50 mm
New size: 766 × 766 × 50 mm
For this version, the redesign mainly involved adjusting the overall tray size while maintaining the required structural concept and product function.
FH® Alloy completed the revised geometry and produced the final 3D model based on the updated size requirement.
This shows FH® Alloy’s ability not only to modify height or local features, but also to develop a resized product based on an existing design platform.

From Existing Product to New Product Development
One of the most valuable aspects of this project is that the redesign work was based on a combination of:

• existing product dimensions,
• updated target dimensions,
• customer-marked modification areas,
• and a real photo of the current product.

FH® Alloy converted these inputs into a technical workflow:
Existing Product Review
↓
Customer Modification Request Analysis
↓
Dimensional Adjustment
↓
Structural Redesign
↓
3D Modeling
↓
Manufacturing
↓
Final Inspection

Delivery
This process is highly relevant for customers who do not necessarily need an entirely new product family, but instead need a supplier capable of upgrading and optimizing existing furnace tooling.

Design Features of the New Trays
The final redesigned models reflect a technical approach focused on practical use and manufacturability.
Optimized Open Structure
Both redesigned trays use an open structural pattern, which helps reduce unnecessary weight while maintaining support capability.
Geometry Based on Existing Proven Designs
Rather than starting from zero, the new trays were developed from existing product logic, helping ensure that the redesign remained application-oriented.
Conversion of Customer Markups into Engineering Models
The annotated product image provided by the customer was translated into a precise design model by FH® Alloy’s technical team.
Two Different Redesign Paths
This project demonstrates that FH® Alloy can handle more than one redesign logic within the same project:

• one version with height modification
• one version with overall dimension modification

Material: 1.4852 Heat-Resistant Alloy
The customer specified 1.4852 for the redesigned trays.
1.4852 is widely used in high-temperature industrial applications because of its good performance in furnace-related environments.

For heat treatment trays and furnace tooling, this material offers advantages such as:

• good heat resistance,
• oxidation resistance,
• structural stability at elevated temperatures,
• and suitability for repeated thermal service.

For FH® Alloy, material selection is always evaluated together with structure and application requirements, so that the final design is not only dimensionally correct but also practical for long-term use.

Manufacturing Process
After the final models were confirmed, FH® Alloy proceeded with production of the redesigned trays.

The manufacturing stage included:

• production according to approved drawings,
• dimensional control,
• structural verification,
• and product finishing before inspection.

Because this project involved redesigned products rather than direct copies, manufacturing accuracy was especially important to ensure the final products matched the newly approved geometry.

Final Quality Inspection
Before shipment, FH® Alloy carried out final quality inspection on the completed trays.

Inspection focused on:
Dimensional Verification
Checking whether the final products matched the revised sizes requested by the customer.
Structural Inspection
Verifying the tray geometry, support structure and overall manufacturing condition.
Drawing Conformity
Ensuring the finished trays were produced according to the final redesigned models.
Shipment Readiness
After inspection was completed, the products were prepared for delivery to the customer.

Complete Project Execution
FH® Alloy handled the full process:
Design → 3D Modeling → Manufacturing → Final Inspection → Delivery

More Than Build-to-Print Manufacturing
This project highlights an important strength of FH® Alloy.
Many suppliers only manufacture according to completed drawings. In this case, the customer did not simply provide a final production drawing and ask for fabrication.

Instead, the customer needed a supplier who could:

• understand the existing product,
• analyze the requested design changes,
• develop a new version,
• and then manufacture the updated product.

FH® Alloy provided exactly that support.
This makes FH® Alloy a valuable partner for customers who want to upgrade, optimize or replace existing heat treatment trays and furnace tooling.
