The ALES PRES Advantage
With decades of engineering experience in eccentric press technology, ALES PRES offers user-friendly, efficient, and long-lasting machines. Our high-precision solutions meet the needs of modern industry.
It is a mechanical press that works with a flywheel and crank system.
It is determined during design based on the table size.
It depends on the stroke length and type of work to be done.
Main selection criteria are press capacity, stroke length, and speed. Crankshaft systems are usually not preferred for strokes over 300mm.
Yes, with proper design. To reduce brake wear, hydraulic brake/clutch systems are recommended.
Yes. At Ales Press, all models have fully automatic stroke adjustment.
According to DIN 8651, it’s 1mm per 8 meters, or 0.125mm/m.
Also per DIN 8651, 0.03mm per 100mm stroke.
Depends on the production process. Ear protection is recommended for noise over 80 dB.
Yes, about 20 dB reduction is possible with partial or full sound insulation.
Roughly half of installed power, but exact data requires a separate electric meter (offered optionally).
Yes, by using regenerative drives in motors to recover reverse forces.
Mostly depends on the clutch system and is calculated accordingly.
Depends on the type. Vibration isolating springs under the press reduce force and vibration transfer to the ground.
Up to 60/40 imbalance is typically allowed depending on design.
Yes, but for longer life, 80% of max capacity is recommended.
Partially yes, depending on stroke and press specs. For deeper drawing, hydraulic presses are better.

Yes, for better precision. But it’s expensive and used in special applications.
Depends on size and weight. Usually required for presses over 200 tons.
Yes, with PLC and industrial PC + remote systems. Full remote use is usually limited for safety.
With full automation and robots, yes — but operator supervision is still needed for safety.
No. It needs specific oils to lubricate gears and components via a central lubrication system.
Based on part cycle time, downtime, breakdown rate, and energy usage.
It’s unsafe, cannot be sold/used legally in Europe, and poses serious risks.
Check tonnage, table size, stroke, speed, safety systems, energy efficiency, and service support.
Typically 2 years for parts made by the manufacturer; third-party components follow their supplier’s warranty. Warranty is void if due to operator faults, unauthorized access, or lack of maintenance.
Yes, if cost-effective — but it must pass full inspection, crack and balance tests, and safety system checks. Older machines may not meet CE requirements.
Main factors are tonnage, table/stroke size, automation level, brake/clutch type, and brand of components.
Forming, deep drawing, flattening, etc., are also possible with special dies, depending on the press.
Yes. Operators must be trained and have a Ministry of Education (MEB)-approved certificate for heavy machinery.
Automotive, white goods, HVAC, furniture fittings, electrical panels, kitchenware, and panel radiator production.
