Muller has mastered 24/7 lights-out coil-fed machining with precision and efficiency

What is lights-out coil-fed machining?

Lights-out machining means running machines unattended (both conventional and CNC machines), often overnight or over weekends, without operators on site. Coil-fed machining takes raw metal coils – typically steel, aluminium, brass or stainless steel – and feeds them directly into the machine, streamlining material handling and improving efficiency.

High-speed and high-volume machining are a powerful combination. This technology allows Muller to:

• Operate machines 24/7, maximising output
• Maintain consistent precision with minimal downtime
• Reduce labour costs and human error risks
• Support complex parts with tight tolerances

What does this mean for you? You get the kind of throughput and consistency that global supply chains demand without the stress of scaling your workforce to match. Automated precision doesn’t call in sick or take breaks. It simply delivers, shift after shift, ensuring repeatable quality across global supply chains.

Why is it important?

Let’s face it – electronics manufacturing isn’t slowing down. With markets accelerating thanks to 5G, IoT, automotive tech, and wearables, the pressure is on. You need volume, accuracy, and resilience baked into your supply chain and it’s clear why smart manufacturers are rethinking their production strategy.

Supply chain disruptions also highlight the need for reliable, local subcontract partners whilst sustainability goals push manufacturers toward efficient, low-waste machining. This means automation and smart manufacturing are key to staying competitive in a crowded market.

Muller England’s 24/7 lights-out coil-fed machining service delivers exactly that. By automating production with minimal human intervention, manufacturers can enjoy continuous, uninterrupted machining that saves time, cuts costs, and boosts output without sacrificing quality.

Coil-fed machining is used to produce:

• Connectors
• Pins
• Screws

These might be small components, but they’re mission-critical, and when you’re dealing with hundreds of thousands at a time, repeatable quality and minimal downtime are non-negotiable. Using coil-fed technology, electronics manufacturers can produce these parts in high volumes with minimal downtime, supporting both batch and mass production.

Demystifying the process

As we all know, it is always behind the scenes where the magic happens. But let’s break down how:

1. Setup & programming: programmes are customised to your specifications, with toolpaths and parameters tuned for efficiency and accuracy.
2. Coil feeding: raw metal coils are loaded into automated feeders that supply the machine continuously, reducing manual material handling.
3. Automated machining: the machines carry out precision cutting, milling, or turning operations around the clock with barely any reliance on human input.
4. Quality control: Integrated sensors and real-time inspection systems ensure every part meets exacting standards in real-time.

We stand out to benefit you

Continuous Production

We don’t just work hard; we work smart. Lights-out capability means Muller machines don’t stop when the sun goes down. That’s more uptime, fewer delays, and one less thing for you to worry about.  

Improved Efficiency

Automated feeding eliminates load/unload delays, reduces setup times, and maximises production hours. Continuous machining slashes lead times and helps meet urgent deadlines.

Cost Savings

Both less material waste and reduced labour and scrap translate into better margins. Continuous feeding results in less offcut waste compared to bar-fed methods.

Labour Reduction

In an industry facing ongoing labour shortages, our setup doesn’t blink. It just runs. You get a consistent, high-quality output without depending on hard-to-fill shifts or costly overtime.

Scalability

Easily adapt to increased production demands without the need for significant retooling. From prototype runs to mass manufacture, Muller adapts to your volume demands.

Quality Assurance

Automated doesn’t mean hands-off when it comes to standards. We’re ISO certified and obsessive about tolerances, and our in-house inspection processes keep things sharp from start to finish. Every component gets the attention it deserves – even when we’re running 24/7.

Real experience in real industries

We’ve been in subcontract machining for almost 100 years, serving some of the most demanding sectors. We know the standards. We know the stakes. And we know how to deliver what matters – on time, every time.

What are you looking for?

We’re not here to tell you what you want. We’re here to deliver it. Based on years of industry insight, here’s what our customers typically prioritise:

• Speed & reliability: Quick turnaround without surprises.
• Precision & consistency: Tight tolerances and repeatability.
