Why More Panel Builders Are Choosing Automated Wire Processing

The pressure on panel builders continues to increase. Customers expect shorter lead times, projects are becoming more complex, and skilled technicians are increasingly difficult to find. At the same time, quality standards continue to rise.

Despite these challenges, wire processing is still largely carried out manually in many companies. Wires are cut to length, stripped, fitted with ferrules or contacts, marked and sorted. These repetitive operations require precision and experience, but they also consume valuable time and are susceptible to human error.

This is where automation can make a significant difference.

Automation Does Not Mean Replacing Everything

When companies think about automation, they often picture a fully automated production line. In reality, the transition is usually much more gradual.

Many manufacturers begin by automating a single time-consuming process, such as cutting and stripping wires or applying ferrules. Once the benefits become clear, they expand automation step by step.

This phased approach lowers the investment threshold while allowing companies to adapt automation to their production environment.

Where Is Time Lost?

When analysing the complete production process, most inefficiencies are not found during panel assembly itself but during wire preparation.

Typical tasks include:

• selecting the correct wire;
• cutting wires to length;
• stripping insulation;
• applying ferrules or contacts;
• marking wires;
• sorting finished wires.

Each of these operations must be performed accurately. A mistake during preparation often only becomes visible during assembly, resulting in delays, rework or unnecessary costs.

By automating the preparation process, production becomes more predictable and consistent.

Reducing Dependence on Experience

Manual wire processing relies heavily on the skills of experienced operators. Skilled technicians work faster and are more likely to detect deviations before they become problems.

Automated wire processing introduces consistency into the production process. Machines perform operations according to predefined parameters while guiding operators throughout production.

As a result, quality becomes less dependent on individual experience and remains consistent across different operators and shifts.

Sequential Wire Production: An Often Overlooked Advantage

In panel building, producing a correct wire is only part of the process. The order in which wires are installed has a major impact on assembly time.

Producing and bundling wires in the correct installation sequence allows technicians to install them immediately without searching or sorting.

For many panel builders, this reduction in assembly time delivers even greater productivity gains than wire processing automation alone.

Quality Starts Before Assembly

Quality is often associated with the finished control panel. However, many problems originate much earlier in the production process.

Incorrect wire lengths, improper stripping or inaccurate marking may seem like small issues, but they can lead to delays, rework and unnecessary troubleshooting during assembly.

Automating these critical operations creates a repeatable process in which every wire is processed consistently.

Which Processes Can Be Automated?

Modern automation extends far beyond cutting and stripping wires.

Depending on the application, automation can include:

• cutting wires to length;
• stripping insulation;
• crimping ferrules or contacts;
• wire marking and identification;
• bundling wires according to installation sequence;
• taping wires or cable bundles;
• protecting connections using Low Pressure Moulding.

The most suitable combination depends on production volumes, product variety and the required level of flexibility.

When Does Automation Make Sense?

There is no fixed production volume at which automation becomes worthwhile.

In practice, companies benefit most when they:

• regularly perform similar wire processing tasks;
• want to increase output without hiring additional staff;
• aim to improve quality consistency;
• want to reduce assembly time;
• seek to minimise errors and rework.

Automation is therefore not an objective in itself, but a way to make better use of available resources.

Automation Starts with Understanding the Process

Successful automation projects rarely begin with selecting a machine.

They start by asking a simple question: Where do we lose the most time, and where do most errors occur?

Once these bottlenecks have been identified, it becomes much easier to determine which processes should be automated. In some cases, a relatively small improvement delivers significant gains. In others, an integrated automation strategy is the logical next step.

For that reason, successful automation always starts with a thorough analysis of the production process.
