HACO Product Lines We Repair
Our engineers are trained on the full HACO product range. Below are the major product families we service.
HACO Hydraulic Shearing Machines
Heavy-duty hydraulic guillotine shears with proportional valve control and manual/CNC feed systems. Common faults include valve spool stiction, proportional coil burnout, pressure switch failure, and encoder signal loss on power clamps.
HACO Press Brake Systems
CNC-controlled hydraulic press brakes with proportional directional control valves, load-sensing pumps, and position feedback. Repair demands often involve tändem-axis synchronization faults, proportional valve hysteresis, and encoder/LVDT calibration drift.
HACO PLC-Based CNC Controllers
Proprietary HACO CNC systems running hydraulic machine sequences, axis coordination, and safety interlocks. Typical issues: firmware corruption, analog input module faults, Ethernet gateway card failure, backup battery depletion, and memory loss of calibration parameters.
HACO Proportional Valve Assemblies
High-response proportional directional and pressure control valves with integrated electronics for closed-loop machine control. Failure modes: solenoid armature stiction, spool wear-induced leakage, pilot pressure regulator malfunction, and onboard amplifier board degradation.
HACO Electro-Hydraulic Feedback Systems
Position sensors (LVDT, inductive), pressure transducers, load cells, and encoder-based feedback for real-time machine control. Common repairs: LVDT non-linearity, transducer zero-drift, cable connector corrosion, and analog signal conditioning circuit faults.
HACO Power Supply and Safety Modules
Industrial 24 VDC power supplies, safety relay modules, emergency stop circuits, and solenoid pilot valve driver cards. Recurring faults: capacitor aging, relay contact welding, pilot solenoid coil burnout, and PCB solder joint cracking under vibration.

Common HACO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HACO equipment arriving at our workshop.
- ✓Proportional valve solenoid coil burnout — HACO proportional valves experience coil failure due to sustained over-voltage spikes from pump surges, damaged suppression diodes, or contamination-induced armature friction causing excess current draw. Indian sheet metal and automotive shops operating in dusty environments are particularly affected.
- ✓CNC controller firmware corruption or boot failure — HACO HM-series controllers lose firmware integrity due to power surges during electrical faults, corrupted memory flash from interrupted downloads, or aging backup batteries. Partial boot loops and loss of stored machine recipes are typical symptoms.
- ✓LVDT position sensor signal drift and non-linearity — HACO shearing and press brake machines rely on LVDT feedback for blade alignment and bend angle precision. Mechanical stress, thermal drift, and connector corrosion degrade sensor linearity, causing machine-positioning errors of 0.5-2mm—catastrophic for tolerance-critical parts.
- ✓Pump pressure relief valve stiction and leakage — Hydraulic contamination and microcracks in HACO pump relief spool surfaces cause erratic pressure spikes (overshooting 10-15% above setpoint) and slow response. Indian foundries and stamping plants with poorly maintained filtration see frequent issues.
- ✓Encoder signal loss and axis desynchronization on dual-axis press brakes — HACO Synchro 3000 and Compact 2000 XL machines experience encoder cable chafing, connector pin corrosion, or internal quadrature channel misalignment. Left-right ram synchronization drifts by 3-5mm, causing part scrap and machine alarms.
- ✓Safety relay module contact wear and false lockout — HACO 4-channel safety modules endure millions of emergency stop cycles in high-speed production. Relay contacts become sticky or weld together, preventing machine restart or triggering nuisance shutdowns, halting production for hours.

Frequently Asked Questions — HACO Repairs
Do you repair HACO equipment anywhere in India?+
Yes. Synchronics repairs the complete HACO product range including hydraulic shearing machines, press brakes, CNC controllers, proportional valves, and electro-hydraulic feedback systems. We offer PAN India door-to-door pickup from all major cities—Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. All repairs are performed in our ISO-certified facility in Vadodara, Gujarat, with OEM-grade diagnostics and component-level restoration.
What HACO CNC controller models do you repair?+
Synchronics specializes in HACO HM-100, HM-200, and ProControl CNC systems. We repair firmware corruption, replace faulty analog input modules, restore Ethernet gateway functionality, replace backup batteries, and recover lost calibration data. We also handle HACO proprietary safety ladder logic and axis synchronization faults. All repairs include full software validation and test cycles to ensure safe, reliable operation.
Can you recalibrate HACO proportional valves and feedback sensors?+
Absolutely. Synchronics offers bench calibration of HACO NG10/NG16 proportional valves, LVDT position sensors, pressure transducers, and load cells. We use precision reference equipment and perform full pressure/position curve mapping to restore equipment to HACO factory specifications. Calibration certificates and before/after performance data are provided for all repairs.
How long does HACO machine repair typically take?+
Standard HACO repairs (proportional valve replacement, sensor recalibration, CNC module swap) take 5-7 working days. Complex issues—firmware corruption recovery, multi-axis synchronization troubleshooting, or complete control panel rebuild—may take 2-3 weeks. Synchronics provides free daily progress updates and expedited service for critical production downtimes affecting Indian manufacturing schedules.
Do you stock HACO spare parts and OEM components?+
Synchronics maintains inventory of common HACO replacement parts including proportional coils, solenoid pilot valves, backup batteries, relay modules, power supply units, and feedback sensors. For specialized or scarce items, we source directly from HACO Belgium or authorized Indian distributors. Emergency same-day dispatch is available for Vadodara and nearby regions to minimize production loss.
How do I send my HACO unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HACO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HACO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HACO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
