Engineering
Prototype To Production
More than 20 years of experience, the latest in CNC-production, highly-skilled employees, top-rated materials high tech coating and hardening satisfy highest needs in individual prototyping.
Sustainable Hybrids
The combination of a rotary engine and a range extender leads to an immensely potent compilation. These powerful and advanced hybrids convince users by their reliability, the favourable power to weight ratio and very low emissions.
Air, Land and Water
When an engine’s power, weight and flexibility are crucial the rotary engine is a safe bet. It has versatile uses in automotive, aeronautic and watercrafts.
From Idea to Product
Our work includes the complete product development cycle. This includes consulting, design, simulation, prototypes and serial production including organisation and documentation.
We have backgrounds in various engineering disciplines and can contribute experience from a large variety of applications.
Customisation and Integration
Our activities, especially on rotary engines, go beyond the standard end product. Sometimes customers need specific functions and packaging solutions. Then we provide assistance and sometimes also a new engine design, and in return some of the new things we create become standard at a later stage. This makes cooperation a win-win-situation both for customers and ourselves.
For example, the Aixro XP40 was first an Aixro XF40 that was modified as a batch production for a paramotor customer. Now the XP40 is a standard product that does not just suit paramotors, but several other applications.
Analysis and Solution
Despite extensive testing and more than a century of experience, products in large industries such as automotive can still be far from optimal. Then it is essential to detect root causes and to find smart and robust solutions. For example, on a specific engine generation, an operating rod that controls swirl flaps tends to fall off, and the manufacturer recommends a very expensive repair. We analysed the failure and developed an improved solution, which is much cheaper for the end customer and fully solves the problem.
System Engineering
The key to good engineering is understanding a system. Solving individual problem areas is no good unless the interactions and impact on the complete system are taken into consideration. Otherwise one solution results in one or more problems in other areas.
When Woelfle Engineering was founded, the first customer was an American manufacturer of embroidery machines. Initially we were approached to solve urgent technical issues on a new product. In the end we remained contractors for several years and also developed a new series of machines for them. This is only one example of many, where a small project turns into more bigger projects and where the basis of success is a combination of the full understanding of a system and a creative solution approach.
