Stamfag AG

Thanks to our longstanding experience, we’re able to provide competent advice in all matters relating to punch through and counter-pressure die-cutting.

Important is the right choice of tool quality: The higher the number of products the greater the demands on the tool. High-quality punching tools may cost more to purchase but work out significantly cheaper when it comes to long runs. Use our tool quality comparison diagram to see the difference.

With higher quality tools requiring less re-sharpening and replacing of crowns or complete dies, machine downtimes are substantially reduced especially on automatic punching machines.

Cargrind, Stamfag’s professional, Swiss-made sharpening machine, fulfills all your sharpening needs. In the absence of automated punching tool sharpeners for complex die-cutting tool shapes, we use this manual, convenient and uncomplicated machine to sharpen all steel and carbide tools at Stamfag. To find out how to use the Cargrind sharpener, simply attend our basic and advanced training courses.

If you are having several punching tools re-sharpened externally every day, we recommend acquiring a Cargrind sharpening machine and attending the training course. The machine will pay off in no time and the sharpening know-how will remain in your company.

We also offer a range of related products and services. Why not benefit from our expertise and ideas, tools and accessories or advice and services if you want to find the most efficient, flexible, cost-effective and safe approach to carrying out your punching operations.
Waste slitters
The waste slitters holders are screwed to the punching tool base. Customers determine the number and position of the slitters which are then adjusted to the cutting material and the Punching machine. Both waste slitters and holders can be bought separately.
 
DMS-16 pressure measuring system
Complex, and therefore expensive punching tools are particularly prone to breakage if the cutting waste dos not fall cleanly from the tool or the tool loses its sharpness. The cost of tool repairs, crown replacements, transport, downtime and delayed deliveries is a powerful argument in favor of buying a DMS system. In case of a tool crown overload, up to 4 integrated pressure sensors embedded in the tool’s sensitive spots switch the punching machine off in milliseconds to avoid possible breakage. The DMS control allows for digital data, including tool number, production figures, pressure data relating to declining sharpness, machine strokes, etc., can be analyzed via the network. The DMS unit is tool-related a and independently applicable to all your punching machines.
 
Blowing Unit BU-1014
Using a BU-1014 blowing unit with high air pressure to remove waste material from the punching tool enhances the safety, efficiency and clean operation of your punch press.
