In projects where standards are exceeded in production lines, sheet thickness reaches from millimeters to centimeters, and giant tenders for millions of parts are involved, ordinary press machines are insufficient. The most critical investment that determines a factory's true production power and the volume of tenders it can enter is undoubtedly the "heavy hitters" in its machinery park. The 160-ton eccentric press machines we manufacture as Karmaksan Machine offer businesses unlimited freedom in sheet forming and heavy forging operations.

All operations that require a heavy sheet bending press, such as automotive main chassis, industrial tube and tank covers, defense industry armor plates, and giant building profiles, take shape in seconds in the body of these 160-ton giants. With our mechanical experience gained since 1988, we not only control this massive power but also transform it into the most efficient worker of your factories with millimeter precision.

H-Frame and Reinforced C-Frame Body Technology

When talking about a 160-ton machine, the biggest engineering problem is the flexing and vibration that the massive kinetic energy will create in the machine body. If the press chassis cannot absorb this power and reflects it outwards, the male and female parts of your molds will rub against each other and blunt, the parts will come out off-size, and ultimately the mold will break. As Karmaksan, we offer our customers two different unshakeable body options at this tonnage: Reinforced C-Frame and H-Frame chassis, known as closed body eccentric presses.

In particular, our H-frame eccentric press designs theoretically reduce the axial deviation at the moment of impact to 0% thanks to their 4-column (column press) closed architecture. Thick ST-52 steel plates formed by laser cutting are woven with special gas-shielded welding robots and subjected to thermal stress testing in a giant furnace. Thanks to this technology, the progressive molds worth millions of liras that you attach to the machine maintain their precision at the first strike exactly even at the millionth strike.

Automation Era: Robotic Sheet Loading and Servo Drivers

Manual (human-powered) feeding of a 160-ton press is a primitive method that is both very slow and carries huge safety risks. Karmaksan Machine designs all the heavy-tonnage machines it produces ready for "dark production" (unmanned factories) in accordance with Industry 4.0 norms.

The advanced PLC systems that make up the main brain of our machines can communicate directly with other automation units in the factory. Our press processes signals from pneumatic sheet feeders, servo drivers, coil unwinders, and even robotic sheet loading (pick & place) arms in milliseconds. When the machine ram reaches its peak point, it gives the robot the command to "place the sheet," and the moment the robot withdraws, it strikes again. This continuous stamping press synchronization raises the number of parts your business will produce in a shift to unimaginable levels.

Power Control: Pneumatic Clutch and Helical Gear Transmission

Standard flywheel-driven presses lock the motor at these massive tonnages. In our 160-ton machines, we reduce the speed and maximize the torque by first transferring the motor's power to a giant flywheel, and from there to custom-made steel gear groups with helical angles. In this way, the machine does not experience the slightest strain while crushing thick steel or armor. Especially in hot forging press operations or deep drawing of thick-walled materials, this torque is of vital importance.

Of course, old-generation mechanical (rigid clutch) systems can absolutely not be used to stop this massive power instantly. In all our 160-ton models, pneumatic clutch and brake (air-clutched) systems that brake in milliseconds in accordance with CE occupational safety standards are standard. At the slightest intervention to the light barrier or dual hand button, the multi-ton system is instantly pinned down.

Critical Technical Equipment of Our 160 Ton Models

• Motorized Ram Adjustment and Digital Display: A motorized system connected to the PLC screen that allows you to adjust the massive ram group up and down to the millimeter.
• Hydraulic Fuse (Overload Protection): A fuse system that saves the mold and crank from breaking by instantly discharging hydraulic oil during loads exceeding 160 tons, such as two sheets accidentally entering the mold.
• Pneumatic Balance Cylinders: A system that protects brake pads and gears by suspending the weight of heavy mold upper parts and the ram with air pressure.
• Central and Time-Adjusted Lubrication: Equipment that automatically lubricates all moving slides, crank, and connecting rod bearings via PLC during production.

Comprehensive Revision Solutions for Heavy Presses

Buying a brand new 160-ton machine can be a major investment item. If you have an old and inefficient heavy press with a mechanical clutch that works in your facility but does not meet occupational safety norms; you can renew it with Karmaksan expertise instead of scrapping it. Among Turkey's leading press revision companies, our team recreates all your old giant machines from scratch in our factory regardless of the brand.

With the micron-precision turning of worn slides and bearings, the installation of a new generation pneumatic clutch and hydraulic fuse, and finally full-touch PLC screen integration, your old steel construction heavy press gains all the technological features and CE safety certificate of a brand new machine straight from the factory.
