Manufacturing Technology

WAFIOS Umformtechnik is ideally equipped to support users in machine selection, tool design and construction – whether that’s for machines from its own portfolio or for cold forming machines from other suppliers. 

WAFIOS Umformtechnik GmbH has been developing and producing high-quality cold formers for more than 100 years. The forming specialist is also a partner to users in feasibility studies and tool development – with users benefiting from the company’s decades of experience and know-how. 

This includes the design of forming processes (stage progress) where WAFIOS’ system can simulate volume, compression, reduction and cup ratios, as well as the approximate pressing force, which is particularly helpful for a general machine selection. The company can also simulate the transportation and feeding of pressed parts in order to determine the ideal gripper dimensions. The tools are also drawn in simplified form for this purpose.

As part of its capabilities, WAFIOS has special 2D material flow simulation software that can be used to precisely analyse the material flow in order to detect any wrinkles or other defects at an early stage. Different stresses, forces, etc, are calculated both on the product and on the tool. This is particularly useful for complex products and should always be carried out in advance.

In addition to the 2D software, the company is able to provide a 3D material flow simulation system, which means even the most unusual contours and geometries can be depicted in three dimensions. A 360 degree simulation can also be used to recognise possible buckling in the material, which can occur if the compression ratio is too high or the tool has not been ideally designed.

“By working with customers, we can support them in machine selection, tool design and construction to fit their requirements,” concludes WAFIOS Umformtechnik. “On request, fastener manufacturers will receive the finished design and are assisted in commissioning the process on-site.”
