Vision and mission
Wollenberg’s vision and mission

Our goal is satisfied customers. Simple as that.

In order to reach this goal, top-notch service and quality are our guiding lights. Our customers’ projects are our obligation!


Wollenberg is to be the preferred partner in assignments involving complex metal components and systems, through innovative value generation.


Wollenberg is an extremely creative enterprise with its finger on the pulse. In practice, this means that Wollenberg goes the extra mile to optimise and rationalise production using its own tool manufacture and machine fleet. Our operation is distinguished by our continuous improvement of both the performance and profitability of our processes.

From global goals to everyday aims

Wollenberg is working hard to raise the level – from both scientific and production-technology perspectives. That is why the company has invested in a machine fleet that enables the factory to keep pace with European development. Wollenberg is actively involved in defining the structure of the factory in an everyday context. This structure features strongly Western values such as safety measures on the machines, pay according to qualifications – not on the basis of gender – and helping to educate and upskill both the company’s own personnel and their immediate family. In Asian culture, it is not uncommon to switch jobs regularly and often, as the trade union organisation and unemployment insurance system are not as finely developed as in Denmark.

This means that Vietnamese workers often make tracks for the companies that offer the best pay and working conditions. This is precisely why Wollenberg maintains a high level of pay, as well as high quality meals, work accident insurance, pension schemes and more. These are aspects that are extremely uncommon in the Vietnamese industrial sector. In addition, Wollenberg employs production staff either from the local area or from the immediate family circle of current employees. It is extremely important that the workforce have confidence in one another and know each other in multiple contexts.

Wollenberg is likewise working to enhance the local infrastructure by reinforcing the road network and electrical installations so as to facilitate operations for freight carriers.
