ZWICK Equipment We Repair — By Category
ZWICK Product Lines We Repair
Our engineers are trained on the full ZWICK product range. Below are the major product families we service.
Z010 / Z020 / Z100 / Z250 Universal Testing Machines
Electromechanical and servo-hydraulic load frames for tensile, compression, bending, and shear testing. Common failures include servo valve stiction, load cell signal drift, and crosshead positioning errors. Zwick's proprietary testXpert control software integration requires specialized diagnostic expertise.
testXpert III Control System and Software Interface
Real-time material test data acquisition and feedback loop controller. Repairs involve calibration loss, sensor signal noise, and communication faults between load cell bridge and display unit. Synchronics recalibrates load measurement chains and restores software parameter settings.
Servo-Hydraulic Actuator and Valve Assemblies
Proportional spool valves and linear variable differential transformers (LVDT) for dynamic testing under cyclic load. Seal degradation, valve spool wear, and LVDT coil faults are typical. Zwick systems demand precision rework of hydraulic components and re-zeroing of displacement transducers.
Load Cell and Force Measurement Modules
Strain gauge bridge-based force transducers (typically 1kN to 100kN capacity). Diaphragm rupture, solder joint cracks, and excitation voltage instability cause measurement errors. Synchronics performs complete bridge re-soldering and metrological re-calibration against traceable standards.
Crosshead Drive Motor and Gearbox Assembly
Direct-drive stepper or servo motor with precision ballscrew and planetary gearbox for test frame positioning. Motor winding shorts, encoder signal loss, and mechanical binding in the ballscrew thread are failure modes. Zwick systems require phase-matched reassembly to prevent test specimen misalignment.
Environmental Chamber Integration (Optional Heated Enclosure)
Climatic control box surrounding the test specimen for temperature-dependent material testing (e.g. polymer creep, concrete strength at elevated temperature). Thermocouple failure, chamber seal degradation, and PID temperature loop instability occur frequently. Synchronics restores chamber insulation and re-tunes control feedback.

Common ZWICK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ZWICK equipment arriving at our workshop.
- ✓Load Cell Signal Drift or Offset Error — Strain gauge solder joint cracks due to thermal cycling in Indian climates with high humidity and temperature extremes. Moisture ingress into sealed bridge enclosure causes excitation voltage leakage and nonlinear output across the measurement range.
- ✓Crosshead Position Not Holding or Servo Creep — Ballscrew preload nuts lose tension after 5000+ test cycles. Stepper motor micro-stepping resolution degrades due to encoder signal intermittency or worn optical sensors. Proportional valve spool exhibits hysteresis due to internal friction.
- ✓testXpert Software Error Code 0x1A2B or HMI Display Freezes — Corrupted EEPROM parameter memory due to unexpected power loss during test. Real-time operating system kernel fault in testXpert III on older Z100 units with 16-bit embedded controller. USB or RS-485 communication dropout between load cell bridge module and main PLC.
- ✓Hydraulic Servo Valve Proportional Solenoid Non-Responsive — Proportional solenoid coil resistance drift from 15 ohms to >50 ohms due to thermal aging in non-climate-controlled plants. Spool valve stuck in neutral due to viscosity degradation of ISO 46 hydraulic fluid in tropical Indian factories without proper fluid change schedules.
- ✓Tensile Test Specimen Slips in Pneumatic Grips or Alignment Error — Grip jaw wear flattens the serrated face after repeated testing, reducing friction coefficient. Crosshead misalignment caused by worn ballscrew nut preload or tilted load cell mounting. Specimen contact angle exceeds ±1 degree (Zwick Z250 spec: <0.5 degree off-vertical).
- ✓Environmental Chamber Temperature Overshoot or Thermocouple Intermittency — Thermocouple connector pin corrosion or cold solder joint at chamber controller PCB input stage. PID tuning parameters become unstable after heating element aging or when RTD (Resistance Temperature Detector) drift causes setpoint offset. Chamber door gasket shrinkage allows rapid heat loss.

Frequently Asked Questions — ZWICK Repairs
Do you repair Zwick equipment anywhere in India?+
Yes. Synchronics repairs the full Zwick product range—universal testing machines (Z010, Z020, Z100, Z250 series), testXpert control systems, servo-hydraulic actuators, and load cell assemblies. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are conducted at our 50,000 sq.ft. facility in Vadodara, Gujarat.
My Zwick Z100 shows load cell drift of +/-2% over the test range. Can you fix it?+
Yes. Load cell drift is typically caused by strain gauge solder cracks, moisture ingress, or excitation voltage instability. Synchronics performs full bridge diagnostics, replaces damaged solder joints, applies conformal coating, and re-calibrates the load measurement chain against NIST-traceable reference standards. We provide a calibration certificate post-repair. Typical turnaround is 7-10 working days.
What is testXpert software and why does it fail?+
testXpert III is Zwick's proprietary real-time test control and data logging software running on embedded PLC hardware. It fails due to EEPROM parameter corruption (power loss during test), kernel faults in older 16-bit controllers, or USB/RS-485 communication errors. Synchronics restores EEPROM backups, updates firmware, and replaces communication cables. For legacy units, we can upgrade to testXpert V5 runtime on modern hardware.
How often should I replace the hydraulic fluid in my Zwick servo-hydraulic test system?+
ISO 46 anti-wear hydraulic fluid should be replaced every 2000-2500 operating hours or annually (whichever comes first), especially in non-climate-controlled Indian plants. Fluid viscosity degradation and moisture absorption cause proportional valve solenoid sluggishness and spool stiction. Synchronics recommends fluid analysis sampling at 1500 hours to monitor degradation. We supply OEM-grade ISO 46 fluid and perform full circuit flushing as part of preventive maintenance.
Can you recalibrate my Zwick load cells in-house or do they need to be sent to an external calibration lab?+
Synchronics performs complete in-house load cell recalibration using dynamic load frame reference standards traceable to NIST/NABL. For 1kN to 100kN capacity transducers, we apply stepped load increments, verify linearity across the measurement range, and issue calibration certificates. For specialized high-capacity cells (>100kN) or ceramic strain gauges, we partner with NABL-accredited labs in India. Turnaround: 5-7 days for standard recalibration.
How do I send my ZWICK 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 ZWICK 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 ZWICK 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 ZWICK 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.
