The K Series
Mechanical powder presses from Komage:
Long-lasting, reasonably priced and highly efficient
The mechanical powder presses of the K Series from Komage have been used successfully in global markets for decades. Their durable, robust mechanics combined with the latest control and safety technology are highly valued. So the powder presses of the K Series, for example, are the most widely used standard machines worldwide in the production of carbon brushes. With the integrated cable scissor unit (press-in and cutting device for cables) they have set standards in the productivity of sliding contacts.
The K Series from Komage is particularly efficient for this – and is also well-known as a competitively priced powder press system. With a pressing force of 50 - 500 kN, the powder presses of the K Series are extremely flexible and perfectly equipped for the requirements of continuous use. All powder presses of the K Series operate based on the withdrawal principle.
Advantages of the K Series
- Purely mechanical design with eccentric cam as the drive for the top punch movement
- Short setup times and simple operation
- High stroke rates
- Automatic fill correction
- Pressing to height (position)
- Pressing to density (force)
- Small footprint
- Low energy consumption
- Above-average length of service life
