ARPAC Product Lines We Repair
Our engineers are trained on the full ARPAC product range. Below are the major product families we service.
Shrink Tunnel Control Systems
Temperature regulation modules, conveyor speed controllers, and film tension sensors in ARPAC shrink tunnels. Common faults: thermostat drift, PID loop instability, conveyor encoder misalignment, causing uneven shrink or product jams.
Servo Film Dispensing Units
Stepper and servo motor assemblies controlling film unwinding, cutting, and positioning on ARPAC wrappers. Faults include servo tuning loss, encoder signal dropout, film tension inconsistency, and blade timing errors affecting wrap quality.
Case Erection and Packing Modules
Pneumatic actuators, solenoid banks, and proximity sensors automating case opening, filling, and sealing in integrated ARPAC systems. Issues: solenoid stiction, vacuum pump degradation, sensor hysteresis, causing case jams or misfeeds.
PLC and HMI Control Platforms
Allen-Bradley and Siemens-based controllers managing machine sequencing, fault logging, and operator interfaces on ARPAC packaging lines. Faults: SD card corruption, Ethernet communication timeouts, analog I/O noise, causing production halts.
Conveyor Indexing and Drive Systems
Variable frequency drives, stepper controllers, and synchronization electronics coordinating product flow through multi-station ARPAC systems. Common issues: encoder slippage, VFD overheating, phase loss, timing drift between modules.

Common ARPAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARPAC equipment arriving at our workshop.
- ✓Shrink tunnel thermostat calibration drift — RTD (resistance temperature detector) sensor degradation or loose thermowell contact in ARPAC shrink tunnels operating continuously at 180-200 degrees Celsius. Temperature readings lag or fluctuate, causing uneven shrink application and wrinkled packages.
- ✓Servo film dispensing motor tune loss — Stepper or servo motor in ARPAC FilmServo modules loses commutation due to encoder cable wear, connector corrosion, or firmware drift in servo drive. Film unwind becomes jerky, film tension becomes erratic, cutting precision suffers.
- ✓Case erection solenoid stiction and sluggish actuation — ARPAC case erector solenoids experience internal coil insulation breakdown or armature corrosion from humidity in production environment. Solenoid response time increases, case opening delay causes missed cycle, or cases jam in erector.
- ✓PLC SD card corruption and loss of machine configuration — Sudden power interruption during file write, faulty SD card slot contacts, or age-related flash memory degradation in ARPAC CompactLogix or Siemens S7-1200 controllers. Machine becomes inoperable, operator interface shows 'Config Error', production stops.
- ✓Conveyor encoder slippage and synchronization loss between modules — ARPAC multi-station conveyor systems experience encoder coupling misalignment, shaft creep, or optical sensor contamination from packaging dust. Downstream modules lose real-time position reference, product spacing becomes inconsistent, collisions occur.
- ✓VFD overheating and thermal shutdown in conveyor drive systems — ARPAC variable frequency drives in high-ambient production areas experience heatsink dust accumulation, fan bearing wear, or sustained high-load operation. Drive trips on temperature threshold, stopping conveyor; restart cycling causes product spillage and throughput loss.

Frequently Asked Questions — ARPAC Repairs
Do you repair ARPAC equipment anywhere in India?+
Yes. Synchronics is an authorised repair centre for ARPAC shrink wrapping, case packing, and automated packaging machinery across all of India. We offer PAN India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Equipment is transported to our 30,000 sq ft repair facility in Vadodara, Gujarat, where it receives full diagnosis, repair, and performance testing. Turnaround is typically 5-7 working days for standard repairs.
What specific ARPAC systems does Synchronics repair?+
Synchronics repairs the complete ARPAC portfolio: shrink tunnel controllers, servo film dispensing units, case erection and packing modules, integrated PLC/HMI systems (CompactLogix, Siemens S7-1200), conveyor indexing and VFD drives, solenoid banks and pneumatic controls, and optical sensor arrays. We also repair third-party components (ABB, Danfoss, Schneider, Yaskawa drives) integrated into ARPAC lines, making us a one-stop repair partner for your entire packaging automation system.
How do I know if my ARPAC shrink tunnel temperature controller has failed?+
Common signs: tunnel temperature readings fluctuate or plateau below setpoint; packages come out with loose, wrinkled shrink wrap; or the controller display shows error codes like 'Sensor Fault' or 'RTD Open'. These indicate RTD sensor degradation, faulty thermostat module, or loose electrical connections. Send the controller to Synchronics for RTD recalibration, sensor replacement, and PID loop tuning. We return it calibrated and tested to ARPAC specification.
Can Synchronics repair ARPAC servo film dispensing units without the original motor?+
Yes. If your ARPAC FilmServo module has a failed stepper or servo motor, Synchronics sources genuine ARPAC replacement motors or validates cross-compatible alternatives from ABB, Yaskawa, or other OEM partners. We re-tune the servo drive firmware to match the new motor's electrical characteristics, test film tension repeatability on our bench, and return the module ready for production. Genuine ARPAC motors are preferred, but we can expedite repairs using validated equivalents if OEM lead time is excessive.
What is the average repair cost for an ARPAC case erection module?+
Repair costs for ARPAC case erector modules typically range from 15,000 to 45,000 INR, depending on fault severity. Simple solenoid or sensor replacement costs 15,000-25,000 INR. Complex faults involving mechanical jamming, pneumatic circuit repair, or multiple component failures cost 30,000-45,000 INR. Synchronics provides a free fault diagnosis report within 24 hours of receipt, so you know exact repair cost before we proceed. Genuine ARPAC parts are quoted separately and sourced through authorised distributors to ensure authenticity and warranty.
How do I send my ARPAC 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 ARPAC 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 ARPAC 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 ARPAC 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.
