DOBOY Product Lines We Repair
Our engineers are trained on the full DOBOY product range. Below are the major product families we service.
DOBOY Vertical Form-Fill-Seal (VFFS) Systems
DOBOY's flagship VFFS machines form pouches from roll stock, fill product, and seal in one continuous motion. Common repair issues include stepper motor encoder failures, pneumatic pressure sensor drift, and PLC communication faults affecting cycle synchronization.
DOBOY Horizontal Form-Fill-Seal (HFFS) and Pillow Pack Lines
Horizontal sealing systems for premade bag filling and horizontal pouch creation. Frequent repairs involve thermal sealing bar temperature regulation boards, conveyor servo drive losses, and bag-detect photocell misalignment causing stoppage.
DOBOY Control Electronics and Motion Modules
DOBOY's proprietary stepper controllers, servo interface boards, and PLC-based sequencing units. Failure modes include stepper driver IC burnout from power surges, relay coil adhesion causing cycle hangs, and firmware corruption leading to error code loops.
DOBOY Pneumatic and Pressure Control Systems
Integrated pneumatic valve manifolds, pressure regulators, and solenoid coils essential for bag formation and sealing actuation. Repairs address vacuum gauge sensor failures, solenoid coil burnout from wet air exposure, and regulator diaphragm rupture.
DOBOY Thermal and Temperature Regulation Boards
Dedicated thermal control PCBs for sealing bar heating, cool-down cycle management, and temperature feedback compensation. Common faults include thermocouple amplifier drift, solid-state relay (SSR) gate isolation failure, and thermistor NTC drift.
DOBOY Sensor and Detection Electronics
Photocell amplifiers, proximity switch interfaces, and product-present detector circuits. Repairs involve photodiode aging in infrared sensors, amplifier offset drift, and pull-up resistor component aging causing intermittent bag detection.

Common DOBOY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOBOY equipment arriving at our workshop.
- ✓Stepper motor encoder output signal loss — DOBOY stepper systems use magnetic encoders for position feedback. Encoder magnets debond from shaft vibration or bearing wear, causing intermittent signal dropout. This triggers position-sync errors and bag-length inconsistency.
- ✓Pneumatic solenoid coil burnout and valve stiction — DOBOY packaging lines often run in humid environments. Moisture ingress into solenoid coils corrodes the wire insulation, causing short circuits. Simultaneously, humidity promotes rust in valve spools, increasing friction and preventing pneumatic actuation.
- ✓Thermal sealing bar temperature overshoot and undershoot — DOBOY sealing bar temperature is controlled via solid-state relays (SSRs) and thermistor feedback. SSR gate-drive isolation degradation or thermistor NTC aging causes erratic heating cycles, resulting in weak seal strength or product melt damage.
- ✓PLC communication timeout and cyclic redundancy check (CRC) errors — DOBOY PLCs communicate with stepper controllers and servo drives via proprietary serial or Ethernet links. Electromagnetic interference (EMI) from packaging line motors, worn USB connectors, or corrupted firmware cause packet loss and CRC failures.
- ✓Bag detection photocell false triggers and missed detections — DOBOY photocell amplifiers degrade due to infrared LED aging, ambient light contamination on sensor lens, or amplifier offset drift. This causes false product-present signals or missed bag detection, halting the packaging line.
- ✓Conveyor servo drive loss of synchronization with bagging rhythm — DOBOY conveyor servo drives lose commutation sync when encoder cable is damaged, motor winding insulation degrades, or drive firmware becomes corrupted. The conveyor stutters or runs at incorrect speed relative to bag formation timing.

Frequently Asked Questions — DOBOY Repairs
Do you repair DOBOY equipment anywhere in India?+
Yes. Synchronics repairs the full DOBOY packaging machinery control electronics range — stepper controllers, PLC modules, thermal sealing boards, pneumatic solenoid interfaces, and sensor amplifiers. We offer PAN-India door pickup and diagnostics from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major cities. All repairs are carried out at our Vadodara, Gujarat facility with 24-hour turnaround for standard modules.
What is the typical repair turnaround for DOBOY stepper motor controllers?+
DOBOY stepper controller modules are repaired within 48-72 hours of receipt. We perform full diode-level diagnostics, replace burned stepper driver ICs with matched specifications, and conduct encoder signal validation and frequency response testing before return. Rush same-day diagnostics and express shipping are available for critical packaging line stoppages.
How do you handle DOBOY firmware corruption and PLC code recovery?+
Synchronics has archived firmware versions for legacy and current DOBOY PLC modules. We recover corrupted code from backup sources, reload via EPROM programmer or Ethernet bootloader, and validate cyclic operation on test rigs. If original firmware is unavailable, we reverse-engineer control logic from hardware circuit traces and customer documentation to restore machine function.
Can Synchronics repair DOBOY servo drives used in conveyor synchronization?+
Yes. We repair DOBOY's servo drive systems that maintain conveyor speed in sync with bag formation timing. Common repairs include encoder cable replacement, motor winding testing, drive firmware reload, and commutation parameter re-tuning. We test restored drives on dynamometer loads to verify speed stability and encoder phase alignment before shipment.
What warranty do you provide on DOBOY machinery electronics repairs?+
Synchronics provides a 12-month parts and labor warranty on all DOBOY equipment repairs, covering defective workmanship and component replacement under normal operating conditions. Warranty begins upon customer receipt of repaired equipment. Extended 24-month warranties are available on critical modules. Warranty terms exclude damage from power surges, improper installation, or misuse.
How do I send my DOBOY 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 DOBOY 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 DOBOY 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 DOBOY 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.
