Welding machines


Your welding task is in the best hands with us - NIMAK C-Module

When it comes to the strength of weld nuts, we can't take a joke! Whether square, round or special nut, whether segment or ring boss, our C-modules ensure that your weld nut is and remains firmly and securely connected to the sheet metal. Of course, we also offer corresponding modules for welding screws and other small welded parts. Our goal is the highest level of quality and durability. To achieve this, we use components manufactured in our own factory, such as cylinders and transformers according to our modular concept. This enables us to supply you with the best solution for your welding task at short notice and at attractive prices.

  • Individually configurable by modular system
  • With pneumatic or servo motor drive, or optional: magneticDRIVE
  • As table-top or stand-alone version
  • Space-saving C-module for welding cells

Benefits in an overview:

Can be individually configured
We fabricate powerful components for the modular system. From us you obtain individually configurable and individually manufactured roller-seam welding machines that are specifically adapted to your welding requirements. To accomplish that we need to have a talk so that our experts can precisely understand the welding jobs you are facing. We cordially invite you.

Robust and tough
We have been developing, designing and manufacturing machines for the roller-seam welding process for more than 50 years. And we have been ensuring the highest quality, which our professionally trained employees ensure every day, for just as long. The result is roller-seam welding machines that work reliably and always provide high-performance in your company for many decades.

Shorter delivery times, good price-performance ratio
Thanks to the principle of the individually configurable modular system, when we develop and fabricate your machine for roller-seam welding we do not need to start from scratch. That generates cost and time advantages that we gladly pass on to you in the form of attractive prices and short delivery times.

Meets all safety regulations
Just as for all our products, true also for the machines for roller-seam welding from NIMAK: They entirely meet the legal safety requirements and satisfy the high requirements of Performance Level D.

Typical applications

Whenever impermeable welding seams are demanded, our roller-seam welding machines perform reliable, continuous work. For example

In the automotive supplier industry, for instance for the production of shock absorbers and also for the manufacture of:

  • Tanks
  • Fire extinguishers
  • Drums, etc.

Technical data
