Manufacturing Insights with FMC: Profiling

Industrial metal profiling is an important foundation in precision friction disc manufacturing. In this second instalment of our Manufacturing Insights series, we take you inside Production Cell 1 at FMC. Profiling transforms raw materials into precise shapes, ready to be made into components and power machinery across the globe.

What is profiling? 

Metal profiling is the process of cutting flat metal sheets or plates into specific shapes. These then become components for machinery. For friction and steel disc manufacturing, the profiling stage is extremely important. This stage defines the overall form of each component and has a direct impact on performance.

Choosing a profiling method

At FMC, selecting the right profiling method is never a one-size-fits-all decision. Our engineers carefully balance cost, quality and application requirements while paying close attention to each project’s specific needs. With decades of experience behind us, we determine the optimal manufacturing approach for everybody.

Wire EDM

Wire Electrical Discharge Machining (EDM) is a precise method for profile cutting. This process uses an electrically charged wire to accurately erode material, making it the method of choice when precision is required.

At FMC, our range of EDM machines is used primarily for manufacturing tooling and gauges. Our quality team regularly uses wire EDM to produce Go/No-Go gauges, ensuring that every component meets the highest standards before leaving our facility.

Precision for parts

For production parts, wire EDM is great for top-level motorsport applications. FMC components manufactured using this method have contributed to multiple world championship victories, where even the smallest thing can affect performance.

Typical tolerances of ±0.005mm can be achieved with wire EDM. The trade-off is speed: cutting rates can be as low as 20mm per minute, making this a premium process reserved for situations where precision is key.

Laser Cutting

Laser cutting remains one of the most widely used metal profiling methods in modern manufacturing.

It is valued for its:

• Flexibility
• Speed
• Accuracy.

At FMC, we use high-quality fibre laser technology. Delivering superior cutting performance across a range of materials.

Minimal waste

Recent advances in cutting gases and process control have significantly reduced errors whilst increasing cutting speeds. To maximise cost efficiency, we employ advanced nesting practices that use as much of the raw steel as possible, minimising waste without compromising quality.

Edge quality is critical in friction disc manufacturing. All the force generated by our friction materials must be transferred through the edges of each component. Laser cutting produces a very straight, consistent edge, meaning the torque can be transferred effectively. This consistency is essential for long-term durability and reliable performance under demanding operating conditions.

Stamping

The process of creating smaller parts in large quantities is streamlined by something called “stamping”.

This process is the fastest and most cost-effective, which is why many high-volume parts in the FMC range are manufactured using hydraulic stamping presses.

Why choose stamping?

While initial tooling costs tend to be higher than other methods, at FMC, our tooling is done in-house using wire EDM and CNC milling machines. Delivering significant advantages like:

• Rapid tool maintenance and repair
• New tooling manufactured at short notice
• Fine adjustment of clearances and die heights to maintain quality

Our press shop operates a range of hydraulic stamping presses for maximum output and efficiency.

Secondary profiling processes 

Once the initial profile is complete, there are often a few more processes required before everything is finished. All secondary operations are carried out by our skilled team in Production Cell 1 and include:

• Turning
• CNC profiling
• Milling
• Gear cutting
• Monitored for quality

Every process is strictly controlled by the FMC quality team, with inspections carried out throughout production. All results are recorded and fully traceable through our ERP system. This ensures complete accountability from raw material to finished component.

Why work directly with a manufacturer?

Partnering directly with a manufacturer like FMC means the correct profiling processes can be built around your specifications,
Our engineering team works closely with customers to understand:

• Performance requirements
• Tolerance specifications
• Production volumes
• Appropriate methods to meet both technical and commercial objectives.

Frequently Asked Questions

What is sheet metal profiling?

Sheet metal profiling is the process of cutting flat metal sheets into specific shapes and geometries for parts. In friction and steel disc manufacturing, profiling defines the overall shape of the part and directly influences things like:

• Torque transfer
• Load distribution
• Assembly fitment

Common profiling methods include laser cutting, wire EDM and stamping.

What is the difference between wire EDM and laser cutting?

Wire EDM uses an electrically charged wire to erode material with extreme precision, achieving tolerances as tight as ±0.005mm. It is ideal for high-performance and motorsport applications where accuracy is critical.

Laser cutting, particularly fibre laser technology, offers faster cutting speeds and excellent edge quality, making it more suitable for medium to high-volume production where both accuracy and cost-efficiency are required.

When should stamping be used instead of laser cutting?

Stamping is best suited to high-volume production runs where speed and cost efficiency are priorities. Although initial tooling costs are higher, once established, stamping provides rapid cycle times and making them easier to recreate. Laser cutting is often preferred for lower volumes or when a flexible approach is needed for designs.

Why is edge quality important in friction disc manufacturing?

All torque generated by friction materials is transferred through the edges of the component. Poor edge quality can affect load distribution and long-term durability. Profiling methods such as fibre laser cutting provide straight, consistent edge conditions.

What is an ERP system in manufacturing?

An ERP (Enterprise Resource Planning) system in manufacturing is software used to manage and track production processes, quality inspections, material batches and traceability. At FMC, all profiling processes and inspection results are recorded within our ERP system, ensuring full traceability and quality control throughout Production Cell 1.

How does manufacturing ERP support quality control?

Manufacturing ERP systems improve quality control by:

• Recording inspection results
• Tracking component batches
• Managing tooling data
• Maintaining full production traceability

This ensures that every part produced meets tolerance and performance requirements while being able to quickly identify issues.
