Quality and Reliability
Quality through craftmanship. At DHM-VOS we believe that quality is a process of continuous improvement. Knowledge gained in previous projects is applied in new projects to deliver even better products.
Quality assurance at DHM-VOS:
- 4-eyes principle in office and workshop
- Well-trained staff
- Certified welders and welding procedures
- Periodic equipment calibration and inspection
- Quality management system according to ISO 9001
- Contact with the customer when in doubt
Quality from step one
Quality does not start with the final product, but with the very first step in the process. At DHM-VOS, we seamlessly integrate process control with final control. This is how we deliver products that meet the highest requirements and expectations.
Origin / Traceability
The origin of materials is an important criterion for judging the quality of a product. Our products are often used under the most extreme conditions. For this reason, our processes, from quotation to delivery, are carefully designed and fully transparent. Traceability is central to this:
To ensure the safest possible operation and longevity, we use only high-quality materials of known and verifiable origin.
Certifications: our quality assurance
Our certifications underscore our commitment to quality and craftsmanship. These certifications demonstrate that we not just meet but exceed requirements. This is the quality you can expect from us.
This international quality management system ensures that all our processes – from design to delivery – are effectively and efficiently designed and subject to cycles of continuous improvement. Every department from logistics to accounting provides input and records data. We use this data to improve. Again and again and better.
This certification is mandatory for steel and aluminum structures in Europe. It demonstrates that our structures meet strict safety requirements and are consistently produced according to controlled processes.
This seal of approval specifically addresses welding quality requirements. This standard ensures that our welding work is performed to the highest quality standards, essential for the safety and durability of our products.
Our LMKs are standardized to EN ISO 15614 LR – We go beyond the required standards by applying the Lloyd’s rules for lifting appliances to our welding processes. This provides additional reliability and safety even in the most demanding conditions.
“Care and Quality are internal and external aspects of the same thing. A person who sees Quality and feels it as he works is a person who cares. A person who cares about what he sees and does is a person who’s bound to have some characteristic of quality.”
Robert M. Pirsig, Zen and the Art of Motorcycle Maintenance: An Inquiry Into Values
“I worked for years as a department head at a mental health institution where we provided work experience for people in trouble. Here several aspects of quality came together. We produced fairly complex metal products for the mainstream market with a usual set of requirements regarding quality and delivery time.
However, the main objective was not production. It was providing structure, success experiences, the need for affirmation but also influencing and learning behavior. One would expect these objectives to be incompatible. Yet much more often, I noticed that harmony emerged and the objectives interlocked as a well-fitting mechanism.
I found the phenomenon articulated in the work of philosopher Robert Pirsig. In his book Zen and the Art of Motorcycle Maintenance, Persig states that when four static qualities (material, form, harmony and background) come together in the right way, a dynamic quality emerges. The result is not a sum of set requirements but a multiplication of added value for all stakeholders. A spiral is created where, in recurring pattern, the old is not lost but forms a basis for the next cycle with an ever deeper and richer awareness of what quality means for all involved in our company.”
