Customer case studies
Wherever high-quality stamped and plastic products are needed, EK stands ready as a development partner and solution provider. With intelligent system solutions and custom-made designs, we support our customers from the initial product idea through new development to quality-tested series production and assembly. We reliably solve your challenges too.
Universal clamp for photovoltaic installation
Problem statement
Our customer used a mounting system to secure PV panels. For the connections, both middle clamps and additional end clamps were required. Using two different types of clamps resulted in higher installation effort and more complex small‒parts management.
Implementation
We developed a universal clamp suitable for all framed module types. By rotating the clamp head by 90°, it can be utilized as both a middle clamp and an end clamp. Thanks to its height adjustment feature, the clamp can also adapt to various frame heights. Furthermore, it is highly user‒friendly during installation: it can be easily inserted and slid into place with a simple "click," locking itself securely as the screw is tightened.
Result
Our universal clamp revolutionizes the installation of PV panels: With its versatility as a middle and end clamp, combined with height adjustment, it simplifies the installation process and significantly reduces small‒parts management. This saves time, effort, and ultimately costs for users—both during planning and assembly.
Problem statement
Our customer regularly struggled with an issue during the assembly of shock absorber spring washers: The upper, smaller washer frequently slipped during installation because its larger inner diameter did not allow for exact positioning relative to the lower washer. This led to assembly errors, increased rework, and an overall unstable production process.
Implementation
In close cooperation with the customer, we developed a brand‒new process: Using a two‒lane rotary indexing welding system with 6 stations and precise laser measurement, the two washers are now exactly aligned and spot‒welded via a computer‒controlled welding robot.
Production is fully automated at a welding frequency of 10,000 Hz and is seamlessly integrated into our CAQ (Computer‒Aided Quality Assurance) and BDE (Production Data Acquisition) systems. Additionally, color‒coding of the washers ensures clear type identification throughout the entire process.
Result
The new welded assembly ensures a permanent, concentric connection of the washers – without slipping, without readjustment. For the customer, this means: a significantly reduced error rate, stable assembly processes, full traceability, and maximum efficiency in series production.

Balustrade clamp – for fixing glass railings.
Problem statement
Our customer used various clamps to fasten glass balustrades. These varied depending on the glass thickness used. This increased the complexity of small‒parts management and construction planning. Employees always had to be careful to use the correct clamp.
Implementation
We developed a new balustrade clamp with an internal mechanism, allowing the clamp to be flexibly adjusted to all relevant glass thicknesses. Individual component assembly is no longer required. Thanks to this innovative adjustment technology, there is no risk of misalignment, as is often the case with traditional glass clamps. In addition, our clamp ensures maximum safety: no slipping of the glass unit, for example due to temperature fluctuations.
Result
Together with us, our customer brought the first adjustable clamp fastening to the market. It is not only attractively priced but also highly cost‒effective: Due to its versatility in adapting to all relevant glass thicknesses and post connections, it significantly simplifies warehousing and consulting. With top quality, easy installation, and an aesthetic design, we are setting new benchmarks in the industry together, saving end customers time and effort while allowing them to rely on a premium product.
Problem statement
Insulating glass production: At the joints of the spacers in the insulating glass edge seal, desiccant can escape during the manufacturing process. Since the ends of the spacer profiles are not always cleanly sawn, the straight connector must seal the joint sufficiently.
Implementation
We have developed an innovative plastic bridge and integrated it into the steel straight connectors to combine the outstanding properties of both materials. This synergy enables optimal and reliable sealing of the profile back according to the tube‒in‒tube principle. Our solution compensates for tolerances when cutting the spacers, improves the efficiency of filling the frames with desiccant, ensures comprehensive sealing at the joints, and reinforces overall stability – a decisive advantage, especially for large insulating glass units.
Result
Our solution compensates for cutting tolerances of the spacers, ensures efficient filling of the frames with desiccant, seals the entire circumference of the joint, and increases its stability (especially for very large insulating glass units). This ensures a reliable and convenient processing workflow, allowing production downtime and costly complaints to be avoided. Our product is the best solution on the market.
