The history of etampa ag
Founded in 1945, etampa has developed into a leading and internationally operating company in the stamping and fineblanking sectors. On 7,200 sqm of factory space, etampa operates lean engineering and high-performance toolmaking facilities and an ultra-modern fineblanking and stamping production plant. Employing around 100 people, etampa also maintains a sales office in Illinois, USA and is majority owner of a joint venture with etampa-metra a.s. in Blansko/Czech Republic. At etampa, most of our customers are based in the automotive, electronics/electrical engineering, construction and medical/safety technology industries.

 

Hans Rudolf Haefeli, a member of the etampa Board of Directors since 1996 and the company’s President and majority shareholder since 2010, took over as CEO of etampa ag in May 2016. The company is based in Grenchen, in the Swiss canton of Solothurn.

After completing his commercial traineeship and his studies to become a Swiss certified trustee, Haefeli soon took over management positions at a medical technology company. In 1987, he established Reoplan Treuhand AG in Bern. He still is the company’s main shareholder and a delegate of its Board of Directors. Mr Haefeli is also a member of other Boards of Directors and Foundation Boards and the President of the Board of Directors of two companies. At the Czech company etampa-metra as, a joint venture with etampa ag, Mr Haefeli is also the majority shareholder and serves as the President of its Board of Directors.

Mr. Haefeli is married with two children and lives in Rüttenen near Solothurn. He likes spending what little spare time he has outdoors.

etampa, a ‘progressive die’ company
Stamping and fineblanking using compound or progressive die technology produces stamped and fineblanked parts whose tools complete many different work steps and are precisely matched to one another. The individual steps in the etampa process chain are also precisely matched to each other. In a nutshell: etampa must itself function like a ‘progressive die’ system, from the very first drawing to the collection of the finished parts by the haulage contractor, to guarantee the final result.

Feasibility, plausibility and productivity
The first step at the start of any new project is the drawing, which may occur at an early or advanced product or part planning stage. Many customers rely on active co-engineering from etampa. They value our expertise and technical input primarily because production can get underway directly under optimum conditions. For this to work, etampa must fully understand the specifications and functionality of the parts to be produced. Only then are we able to define functional tolerances and test regimes. A design worked on together and optimised for stamping exerts a lasting influence on tool engineering, regrinding cycles and a tool's useful life. etampa also shares its insights about small adjustments to the original part blueprints that would mean significant gains in productivity. And where tolerance or material changes would make production more cost-effective. Or if the stamping strip can be optimised to ensure a much lower rate of material consumption.

How customers benefit from our process and technical expertise
The first step at the start of any new project is the drawing, which may occur at an early or advanced product or part planning stage. Although some customers only contact the manufacturer when their product development work is finished, the vast majority prefer to initiate the active co-engineering process at an early stage in order to take full advantage of etampa's stamping and fineblanking expertise.

The ideal situation is when both sides confer at a very early stage of the new part's development because the precision manufacturer's pre-development engineers will then be able to provide input to enhance the knowledge of the product developers, and vice versa. At this early stage it is also very important to establish direct lines of communication not only between the marketing department and the customer's purchasing department but also between engineering and R&D departments and between the manufacturer's and customer's quality management specialists.
