Overview
The Haco HDSY 3100-135 is a CNC hybrid servo-hydraulic press brake from Haco, a Belgian manufacturer with over 50 years of experience in sheet metal fabrication machinery. The HDSY series represents Haco's modern hybrid platform, combining servo-driven hydraulic pumps with the force output of a full hydraulic system. At 135 tonnes of bending force over a 3,100 mm working length, the HDSY 3100-135 targets mid-to-large fabricators who need production efficiency without sacrificing the heavy-gauge capability of hydraulic machines.
The hybrid servo drive delivers energy savings of 40-55% compared to conventional hydraulic press brakes by running the hydraulic pump only on demand. Approach speed reaches up to 180 mm/s and return speed up to 160 mm/s, significantly faster than fixed-pump hydraulic designs. Ram positioning accuracy is ±0.01 mm, enabling consistent bend angle repeatability across production runs. The machine is controlled by the Haco Cybelec TouchBend 400 — a 19-inch touchscreen CNC with 2D and 3D graphical bend programming, automatic bend sequence optimization, and offline programming via Haco's PC-based CAM software.
Haco's HDSY series features a robust welded steel frame with precision-guided ram and synchronized dual-cylinder drive. The CNC back gauge is a standard 6-axis unit (X, R, Z1, Z2 axes) with optional V and W extension for complex gauging. Integrated hydraulic crowning compensates for beam deflection across the 3,100 mm working length, maintaining consistent bend angle end-to-end. Tooling compatibility follows the European Promecam/Wila standard. Haco includes a full suite of safety equipment: Lazersafe front light curtain, rear safety guards, and emergency stop circuits.
As a Belgian manufacturer with established dealer networks across Europe and North America, Haco offers accessible parts and service support. The HDSY 3100-135 competes with the Ermak HYB Speed, Durma AD-R Hybrid, and lower-end Amada HG machines. Pricing for the Haco HDSY 3100-135 ranges from $120,000 to $170,000 depending on back gauge specification, crowning type, and optional angle measurement systems.

Strengths & Limitations
Strengths
- Hybrid servo-hydraulic drive reduces energy consumption 40-55% versus conventional hydraulic machines, delivering meaningful operational cost savings in production environments
- Belgian manufacturer with 50+ years of experience and established North American and European dealer networks provides reliable parts availability and service support
- Cybelec TouchBend 400 control with 2D/3D graphical programming and offline CAM integration reduces setup time and enables complex multi-bend program preparation offline
- 6-axis CNC back gauge with independent Z1/Z2 control enables angled gauging and precise positioning across the full 3,100 mm working length
- Integrated hydraulic crowning system maintains consistent bend angle along the full beam length — critical for long-part bending accuracy
Limitations
- Pricing is higher than Turkish and Chinese competitors (Ermak, Durma, Accurl) offering comparable specifications — buyers pay a premium for Belgian manufacturing and service network
- Cybelec control, while capable, has a steeper learning curve for operators accustomed to Delem-based systems, which are more prevalent in North American shops
- 135-tonne force capacity limits thick-plate bending applications — fabricators regularly bending 10mm+ mild steel or 6mm+ stainless should consider higher-tonnage models

Frequently Asked Questions
01
The Cybelec TouchBend 400 is Haco's standard CNC controller for the HDSY series, featuring a 19-inch touchscreen interface with 2D and 3D graphical bend program visualization. It includes automatic bend sequence calculation, a material and tooling database for springback compensation, and network connectivity for program import/export. Offline programming is available via Cybelec's PC-based CAM software, allowing operators to prepare programs off the machine and transfer them via USB or network.
02
Haco's conventional hydraulic press brakes use a fixed-displacement pump that runs continuously, regardless of whether the ram is moving. The HDSY hybrid series replaces this with a servo-controlled variable-speed pump that only operates on demand. This reduces energy consumption by 40-55% during typical production cycles, increases approach and return speed (up to 180 mm/s and 160 mm/s respectively), and reduces heat generation — which means less hydraulic fluid degradation and longer seal life.
03
Yes. The 135-tonne force capacity is sufficient for bending austenitic stainless steel (304, 316) up to approximately 4mm thick across the full 3,100 mm working length, and thicker gauges over shorter bending lengths. Stainless requires approximately 50% more force than mild steel, so the machine's full tonnage should be considered when programming stainless bending operations. The Cybelec control includes stainless steel entries in its material database with pre-programmed springback compensation values.
