Benefits of Sheet Metal Prototyping in Industrial Equipment Manufacturing

What is prototyping in metal fabrication?

Design validation in custom fabrication tests the reliability of a custom-engineered product beyond what a Computer-Aided Design (CAD) drawing can provide. It is a vital component of the product design and laser-cutting process. A sample of the final product is produced and subjected to rigorous quality control and quality assurance testing to confirm that it performs as required for its intended application. It involves creating digital or physical models to validate the design before mass manufacturing. Studies suggest that up to 70 per cent of design improvements occur after the first operational prototype is evaluated.

Benefits of Sheet Metal Prototyping?

1. Improved design accuracy: Feedback from engineering prototype testing is used to refine and verify the design.

2. Enhanced communication: Rapid prototypes serve as a shared reference for engineers, stakeholders, and clients.

3. Testing manufacturing processes: Engineering prototypes can be used to assess form, fit, function, and manufacturability before mass production

4. Cost savings: Identifying problems early reduces the cost of redesigns and failures later in the process.

5. Risk reduction: Design validation lowers the risk of technical, usability, or market failure by exposing issues early.

6. Faster development cycle: Rapid, iterative prototyping accelerates development and time to market.

7. Early visualisation and testing: It allows designers and engineers to examine a tangible or functional model before production.

Sheet Metal Prototyping Process in Industrial Manufacturing

ELC Group utilises a sheet-metal process, a critical phase in metal fabrication. The process includes;

Design & CAD Phase

Each of our design validation projects begins with creating detailed CAD drawings to test precision and enable simulation testing.

Material Selection

Choosing the right material is paramount to ensure that rapid prototyping mirrors the final production performance. ELC Group uses a wide range of materials depending on the application, including nickel and titanium. For example, our industrial-grade stainless steel is corrosion-resistant and durable, making it ideal for pharmaceutical and medical equipment. Mild steel is strong and cost-effective but requires coating to prevent corrosion. It is ideal for heavy machinery and agricultural equipment.

Laser Cutting and shaping

Behind the scenes, ELC Group utilise our fibre and CO2 laser machining to cut intricate designs and shapes with precision. Our fibre laser offers ease of automation and integrates with CAD, enabling seamless laser cutting.

Bending and forming

The following operations require our state-of-the-art CNC machine, folding and bending, which improve the structural integrity and strength of precision components.

Rolling Sheet Metal

Assembly

Finally, the most critical stage is the assembly welding. Our methods of joining metal are;

1.      TIG welding uses high precision and is effective for thin components of stainless steel.

2.      MIG welding works best for structural materials and works at a more accelerated speed.

3.      Fibre laser welding utilises minimal material deformation and can be up to ten times faster than traditional welding methods.

Surface Finishing

After the main frame is formed, this stage of the prototyping process enhances durability, aesthetics and performance. ELC Group offers a wide range of finishing processes, including anodising, galvanising, powder coating, electroplating and polishing.

Testing and refinement

This is an integral part of the sheet metal prototyping process. We ensure that each product undergoes rigorous quality control tests to confirm that it is safe and functional for real-world applications.

How is prototyping used in industry?

Medical Devices

The medical sector faces a wide range of challenges that require innovative solutions. Design validation serves as a visualisation tool for developing a solution.  One of its core purposes is to test the patient safety and usability of medical devices. An example of a prototype is a laser marking enclosure that requires precise cutouts, ventilation paths, and custom brackets.

Aerospace Equipment

Rapid prototyping allows for greater creativity as complex parts can be made without expensive tooling. Aerospace parts adhere to stringent safety standards and undergo rigorous quality testing. The aerospace industry requires engineers to design and prototype components such as wings, fuselage panels, and engines.

Farming Equipment

Customised design and 3D modelling create great potential for agricultural and irrigation equipment. Rapid prototyping can enhance collaboration between farmers and engineers. This also minimises waste of materials and energy. Real-world examples of prototyping success in the agricultural industry include precision irrigation systems that can reduce watering by 30%.
