Thread former Protodyn® Eco Plus for trapezoidal screw thread

The direct and most reliable route to creating a cost-effective machining concept often involves the use of a special tool; this is also true for the production of threads. Our experts develop customised, cost-effective special tools for threading in all metal materials.​

Our Walter Prototyp thread former is used for non-cutting thread production without birdnesting nor chip-related problems. We also develop and design for specific thread types, depending on customer requirements.

Your advantages:

• ►  very high level of process reliability, even with deep blind-hole and through-hole threads
• ►  impressive tool life coupled with excellent thread surface
• ► fewer tool changes and optimal machine output resulting from high forming speeds and significantly longer tool life
• ► very cost efficient because it can be used for blind-hole and through-hole threads
• ► high level of dynamic tensile strength of the formed thread due to cold work hardening of the thread flanks and thread root
