Start of Production & Crimp Quality at Kabeltechnik: How We Ensure Safety from Day One

Start of Production & Crimp Quality at Kabeltechnik: How We Ensure Safety from Day One

At Kabeltechnik, our focus on quality begins before the first cable is even built. From the early planning phase to final inspection, we apply strict controls to ensure that each crimp, connection and component meets the required standards.

In this post, we want to show two key processes we use to guarantee this:
🔹 CSA – Crimp Section Analysis
🔹 SOP – Start of Production Process

CSA: Crimp Section Analysis

CSA (Crimp Section Analysis) is a destructive test used to check the internal quality of a crimp connection. Once the terminal is crimped onto the cable, we cut it and inspect the cross-section under magnification.

What we check:

  • Crimp height and width – must match manufacturer specs
  • Copper wire compression – all strands must be fully compacted
  • No empty spaces – no air gaps or poor contact

📸 Example from our lab (CSA report dated 21/10/2024):

Result: All measurements met TE manufacturer standards
✔ Crimp height = 0.806 mm (spec: 0.78 ± 0.02)
✔ Widths (CB1/CB2) = OK

SOP: Our Start of Production Process

Before we start producing any cable batch, we follow a full SOP (Standard Operating Procedure) to organize and control every step.

Key steps include:

  1. Customer Requirements
    • Understand specifications, application, and environment

  2. Design & Planning
    • Choose proper cable and terminals
    • Define lengths, insulation, and special markings

  3. Production Setup
    • Load materials, define tooling
    • Apply crimping, labeling, and testing according to design

  4. Testing & Documentation
    • Conduct continuity, insulation, and mechanical tests
    • Create test reports and final quality review before packaging

🔧 This process guarantees traceability, repeatability, and full control from start to finish.

Final Outcome: Certified and Reliable Connections

By combining a well-documented SOP with CSA quality testing, we can confidently guarantee:

  • Safe mechanical connections
  • Reliable current transmission
  • Compliance with OEM and Tier 1 specs

Every crimped connection is backed by process control, test data, and engineering validation. That’s our commitment to quality.

Quality Control in High-Power Cable Manufacturing

Quality Control in High-Power Cable Manufacturing

At Kabeltechnik, quality and safety are key when we manufacture high-current or battery cables. These types of cables are used in demanding environments—like electric vehicles, energy systems or industrial machinery—where failure is not an option.

That’s why we follow a strict quality control process during and after the crimping of large section cables.

Precision Crimping with Rivet Technology

We use hexagonal crimping tools that ensure strong and reliable contact between the copper conductor and the terminal. These machines are designed specifically for large-section cables, and allow for:

  • Precise cable stripping
  • Metric-compliant hexagonal crimp
  • Custom markings (e.g., STARTER (+), part codes)

Example of cable preparation and crimping process:

Quality Control Tests We Perform

Before a cable assembly leaves our facility, it goes through destructive testing to confirm it meets both mechanical and electrical safety standards.

1. Pull-Force Test

We apply a pulling force higher than what the terminal manufacturer requires. This ensures that the crimp is mechanically strong and won’t fail under stress.

2. Cross-Section Analysis

We cut and polish the crimped terminal to examine the inside structure. This allows us to check that:

  • All copper strands have been compressed correctly

  • There are no voids or air pockets

  • The compression is compact and uniform

Some real test samples from our lab:

These steps help us ensure that the cables can safely carry the required current and voltage, and resist the heat and vibration present in real-world applications.

Final Results: Safe and Reliable Power Cables

By combining advanced crimping tools with thorough quality control testing, we can guarantee performance and safety in every high-power cable we deliver.

This process is already in use for several customers—and we’re ready to scale it for new projects that demand the same level of reliability.

Ultrasonic Welding for High-Current Connections: Kabeltechnik’s Latest Innovation

Advancing Cable & Terminal Connections at Kabeltechnik

MAK-12(6)

At Kabeltechnik, we are always working to improve how we connect cables and terminals. One of our latest improvements is a new ultrasonic welding process that we are now using for high-current connections.

This method gives us better quality, more reliable results, and new options for demanding applications—especially in the automotive and industrial sectors.

What’s New?

Until now, we’ve been using ultrasonic welding mainly for splices (joining cables together). Now, we can also use this technology to weld terminals like the one shown in the pictures below.

These terminals are designed for high power (high current), where strength and electrical performance are key.

Take a look at some of the first samples we produced:

Why Use Ultrasonic Welding?

Ultrasonic welding is a fast and clean way to join metal parts using vibrations and pressure, without needing solder or screws.

Its main advantages:

  • Very good electrical contact (low resistance)
  • Reliable and consistent results
  • No need for extra materials.
  • Faster and cleaner than other methods

It’s a great fit for projects like:

  • Electric vehicles (EVs)
  • Battery connections
  • High-power sensors and modules
  • Industrial power systems

Ready for the Future

This new process helps us offer better solutions for customers who need:

  • Strong and stable electrical connections
  • Clean and modern manufacturing
  • Flexible designs for custom needs

Our machines are ready, and our team is trained to deliver these kinds of welds in both small batches and large-scale production.

Let’s Talk

If you’re working on a project that needs high-power connections, or you’re exploring new welding technologies, we’d love to hear from you.
