Assembly solutions

Our solutions enable direct deliveries to end customers or call-off of assembly components from your suppliers. We offer various additional services such as labelling and masking. The result is efficient component handling at a lower cost.


We pack your components and products in suitable packaging depending on the need for product protection and your packaging solutions. We can take care of the purchase and call-off for packaging, resulting in a smooth and cost-effective supply chain.

Direct deliveries

We want to create optimal logistics flows throughout the supply chain. That’s why we deliver the finished products both globally and locally directly to you or the end customer. This helps to shorten lead times while creating positive effects on both the environment and the economy.


The advantage of EDI (Electronic Data Interchange) for you as a customer is primarily to be able to manage and automate orders in an efficient and secure way. It also reduces lead times, administration and sources of error.
