How Zillkon works: efficient contact spring manufacturing from a single source
Why do customers from various industries rely on contact springs from Zillkon? As a manufacturer with in-house development, production, and quality assurance, we offer streamlined processes, fast response times, and technically mature solutions. Whether small batches or large-scale production – our manufacturing processes are closely coordinated from the initial inquiry to final delivery.
Fast Delivery Through In-Stock Availability
One of our key advantages is the immediate availability of many standard products. Numerous contact springs are kept in stock in a variety of versions. This enables us to respond quickly to urgent inquiries and maintain delivery capability even for time-critical projects.
Our structured inventory system provides transparency and supports consistent availability – even during peak demand.
In-House Toolmaking for Speed, Flexibility, and Independence
All tool design, production, and maintenance is handled in-house. This gives us full control over quality and timelines and eliminates reliance on external suppliers. Modifications, optimizations, or repairs can be implemented directly and without delay.
Short communication paths between design, production, and quality management improve efficiency and reduce potential sources of error. Custom requirements such as specific mounting dimensions for connectors can also be implemented quickly and reliably.
Digital Production Planning in Real Time
Our entire manufacturing process is managed using a modern, digitally networked planning system. As soon as an order is received, it is automatically entered into the system. Based on available capacity, machine status, and material supply, a precise production schedule is generated.
Real-time digital planning allows for flexible order management, proactive bottleneck detection, and short lead times. This ensures reliable delivery and full transparency – even for technically complex orders like relay springs or EMC-optimized spring elements.
Precision in Stamping: From Sample to Series
Our stamping processes are designed for maximum accuracy. Custom-developed tools are set up by experienced specialists and thoroughly tested before production begins. During initial sampling, all relevant process parameters are measured and documented, including dimensional tolerances, material behavior, and tool performance.
Once approved by our quality control team, we move into series production, which follows clearly defined quality standards. This ensures repeatability and process stability – even for intricate stamped and bent parts.
Multi-Stage Quality Control for Every Spring
At Zillkon, quality is not just a final check but a continuous part of the manufacturing process. Each contact spring undergoes multiple inspection steps – starting with a visual check and followed by precise measurements using digital metrology.
We monitor critical attributes such as spring geometry, dimensional accuracy, flexural fatigue behavior, and surface characteristics. Only parts that meet all specifications leave our facility.
Material Properties and Application Areas
We manufacture our contact springs using high-performance spring materials such as stainless steel 1.4310, Inconel, or other spring-hardened alloys. These materials offer high bendability, excellent corrosion resistance, and strong performance under elevated temperatures.
For electrically demanding environments such as connectors, relay contacts, or electrical contact points, we pay close attention to conductivity, the relaxation behavior of the material, and compatibility with electromagnetic environments.
We also offer targeted surface coatings to improve contact performance or minimize the risk of contact corrosion, always based on the specific requirements of the application.
Surface Treatment and Packaging with Precision
Many components undergo further finishing steps after mechanical production, including galvanic surface treatment. In cooperation with qualified partners, we provide coatings that enhance corrosion protection, solderability, and electrical properties.
Depending on the product, parts are either sent directly for surface treatment or prepared for packaging. During this step, we also check labeling, packaging compliance, and product protection.
On-Time Delivery Through Coordinated Logistics
Once the final quality checks are complete and all components are released, shipping is prepared. We work with reliable logistics partners both nationally and internationally.
Our logistics team maintains continuous communication with all shipping contacts to ensure delivery deadlines are met and the transport process runs smoothly.
