Ermaksan Green Press Brake 7100-300
The Ermaksan Green Press Brake 7100-300 is a high-tonnage CNC press brake suited for demanding bending applications in automotive parts, HVAC ducting, and light to medium fabrication where long bends, thicker materials, and repeatable accuracy are required.
Overview
- High-tonnage press brake suitable for heavy-duty bending in automotive, HVAC, and light fabrication environments.
- Designed for repetitive production of parts such as brackets, structural components, and duct sections.
- Supports a range of sheet metals commonly used in automotive and HVAC applications, depending on tooling and setup.
- Green series designation typically indicates a focus on energy efficiency and optimized hydraulic or servo-hydraulic operation (exact implementation varies by configuration).
- Best suited for shops needing both capacity (tonnage/length) and consistent bend accuracy across multiple shifts.
What It Typically Costs
Pricing estimate (USD): $250,000 – $900,000 USD
- Lower end of the range generally corresponds to more basic configurations (shorter bed length, fewer axes, simpler controls).
- Higher pricing usually reflects longer bending length, higher tonnage, advanced CNC controls, and additional backgauge axes.
- Options such as offline programming, angle-measurement systems, and automation (sheet followers, robotic integration) can significantly increase total cost.
- Installation, commissioning, operator training, and tooling packages are often separate cost items to budget for.
- Used-market pricing will depend heavily on hours, maintenance records, control generation, and remaining tooling.
Key Selection Factors
- Tonnage capacity – Ensure available tonnage matches your maximum material thickness and bend length for automotive parts and heavier HVAC components.
- Bending length – Check the bed length against your longest duct sections, panels, and structural parts; longer beds improve flexibility but increase cost and footprint.
- Control system and axes – Evaluate CNC control capability (number of programmable axes, crowning, backgauge axes) for complex multi-bend automotive and light fabrication work.
- Repeatability and accuracy – Look for specifications on ram positioning accuracy and repeatability to maintain consistent bend angles across production runs.
- Tooling compatibility – Confirm compatibility with your existing punch/die systems and the availability of tooling for specific automotive and HVAC profiles.
- Energy usage and duty cycle – For multi-shift or high-volume work, consider energy-efficient features and whether the machine is rated for continuous or intermittent duty.
- Ergonomics and safety – Assess guarding, light curtains, foot pedals, and setup ergonomics for safe operation with large panels and long duct sections.
What to Inspect Before You Buy
- Verify the nameplate tonnage and bending length match your required material thicknesses and part sizes.
- Inspect the bed and ram for wear, deflection signs, or visible damage that could affect bend straightness.
- Check the backgauge movement for smooth, accurate travel and confirm all programmed positions are repeatable.
- Test the CNC control: power up, load a sample program, and run through typical bend sequences used in your shop.
- Listen to the hydraulic or servo-hydraulic system under load for irregular noises, pressure fluctuations, or overheating.
- Examine hydraulic lines, seals, and connections for leaks, cracks, or signs of past repairs.
- Confirm all safety systems (light curtains, e-stops, guards, interlocks) function correctly during operation.
- Inspect included tooling for wear, chipping, and correct profiles for your automotive and HVAC applications.
- Review maintenance logs, service history, and any records of major component replacements or upgrades.
- Check electrical cabinets for clean wiring, intact labeling, and any evidence of overheating or moisture ingress.
Buyer Questions
What materials can this type of press brake typically handle? It is generally suited for bending a range of sheet and plate metals used in automotive parts, HVAC ducts, and light fabrication, within the limits of its rated tonnage and tooling.
How do I know if the tonnage is sufficient for my parts? Compare your maximum material thickness, tensile strength, and bend length to standard press brake tonnage charts and ensure a comfortable safety margin above your heaviest job.
Is this machine appropriate for high-volume automotive production? Yes, when configured with adequate tonnage, suitable CNC control, and reliable backgauges, it can support repetitive, high-volume bending of automotive components.
Can it handle large HVAC duct sections? It is designed to accommodate long bends needed for ductwork, provided the bed length and backgauge configuration match your largest panel sizes.
What additional costs should I budget for beyond the purchase price? Plan for tooling, installation, training, electrical and foundation work if needed, plus ongoing maintenance and any software or control upgrades.
How important is the CNC control generation when buying used? Control capability affects programming ease, accuracy, and support options; newer controls typically offer better diagnostics and integration, which can be critical for complex parts.
What maintenance does a high-tonnage press brake usually require? Regular checks of hydraulic fluid, filters, seals, lubrication points, backgauge alignment, and safety devices are typical, along with periodic calibration of the ram and crowning systems.
Can I reuse my existing press brake tooling? Often you can, if the tooling style and clamping system are compatible; verify dimensions and clamping type with the seller before purchase.
Is it suitable for both prototype and production work? With a capable CNC control and flexible tooling, it can handle one-off prototypes as well as repeat production of automotive and HVAC parts.
What facility requirements should I confirm before installation? Check floor space, foundation capacity, electrical supply, and access for rigging to ensure the machine can be delivered, installed, and operated safely.
