About us
High quality cable assembly. Delivered as a partner.
For many years we have supported companies from mechanical engineering, automation technology, special vehicle construction, electrical engineering and industry with the development, manufacture and assembly of individual cabling solutions.
As an experienced manufacturer of wiring harnesses, cable sets and electromechanical assemblies, we accompany our customers from the technical consultation through prototype manufacturing to series production. The result is cable systems that match the application, the quantity and the budget.
Our customers benefit from short response times, a high degree of flexibility and a partnership based approach throughout the project.
Values
What we stand for.
Quality
Consistent quality management and documented inspection processes for a constantly high manufacturing quality.
Flexibility
Short response times and flexible production structures, from the single piece to series production.
On time delivery
MES controlled planning by priority, deadline and customer requirement.
Partnership
One central contact throughout the project and the product life cycle.
History
From a vision to a systems partner.
What began as a vision in 2006 is today a family run business with international reach. For every connection that counts.
- 2006
The vision becomes reality
Company founder Norbert Warda brings decades of experience in cable assembly and a widely branched supplier network with him. His aim: to implement special requirements quickly, without long development times and without the rigid structures of large corporations. In the year of the foundation the first customer specific cable systems, connectors and adapters for vehicle accessories and automotive applications are produced; in 2007 the first collaborations with well known customers follow.
- 2008
Growth through quality
Around 10,000 wiring harnesses and cable systems per year. In 2009 the first fully automatic Komax cable processing machines follow, along with further crimping machines and semi automatic machines.
- 2011
Soldering, ESD and automated testing
New production lines for soldered connections, ESD standards and a system that automatically records electrical tests for pin assignment, resistance and wiring faults.
- 2013
Our own tools and connectors
Development of our own injection moulding tools and connectors. From 2016 mechanical engineering, special vehicle construction and electrical engineering are added as new industries; today we also work for medical technology, robotics, aerospace, motorsport as well as agricultural and heavy vehicle technology.
- 2018
A new generation and digitalisation
Philip Warda joins the family business. Modern ERP systems and production to Industry 4.0 standards follow. In 2019 an intelligent warehouse system with automated storage locations is added, together with seamless batch and process traceability, from the individual cable to the finished wiring harness.
- 2020
High tech machinery
Ultrasonic splicing systems and fully automatic cable processing machines with crimp force monitoring, seal position control and incision monitoring. In 2021 and 2022 an MES for automated order planning follows.
- 2023
Development and technology partner
Our own CAD design office with EPLAN: development of complete cable systems including prototyping, support during series production and documentation to PPAP.
- 2026
Investment in precision
New in our machinery: the semi automatic Komax Delta 260, the Schäfer SealLine 240-1 ADVANCED and the Schleuniger B340, which extends the stripping technology for sensor cables, single strands and multi core cables. To the investments

Our electricity comes from our own system.
Our photovoltaic system with an output of 100 kW supplies the plant in Kitzingen with electricity. Since 20 May 2026 a battery storage unit with 32.4 kWh has stored the surplus. This means we supply 100 per cent of our own electricity all year round.
If the public grid fails, a grid disconnection switch separates the system from the grid, and the photovoltaic system and the storage unit continue to supply the plant. That means additional security of supply for our customers.
