HAWO Product Lines We Repair
Our engineers are trained on the full HAWO product range. Below are the major product families we service.
HAWO Impulse Sealers (Manual & Foot-Pedal)
Portable impulse heat sealers for flexible packaging, laminates, and thermoplastic films. Common faults: uneven seal lines, heating element burnout, solenoid coil failure, and digital timer malfunction affecting dwell and cooling cycles.
HAWO Band Sealing Machines (Continuous)
High-speed continuous band sealers for high-volume pharmaceutical and food packaging. Repair issues include belt wear, temperature control drift, pressure roller misalignment, and electrical contactor failure in main sealing elements.
HAWO Vacuum Seal Systems
Vacuum-sealing units for moisture-sensitive products and extended shelf-life packaging. Common failures: vacuum pump degradation, seal bar heating inconsistency, vacuum valve membrane rupture, and microprocessor control board faults.
HAWO Thermostat & Control Modules
Electronic temperature controllers and solenoid-driven pneumatic valve assemblies regulating sealing chamber heat. Faults include thermostat calibration drift, relay chatter, solenoid coil shorts, and PTC heating element failures.
HAWO Accessories & Replacement Assemblies
Heating strips, seal bars, solenoid coils, and control PCBs supplied as spare parts. Repair scope includes PCB trace damage, capacitor leakage, relay sticking, and connector corrosion from packaging line humidity.

Common HAWO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HAWO equipment arriving at our workshop.
- ✓Uneven or weak heat sealing across seal width — HAWO heating element degradation, thermostat calibration drift, or moisture ingress into the thermal sensing circuit. Damp packaging line environments cause corrosion of heating bar contacts and thermostat sensor leads.
- ✓Solenoid valve fails to energize or chatter intermittently — HAWO solenoid coil insulation breakdown, weakened armature spring, or relay contact pitting in the control circuit. High-humidity food and pharma environments accelerate coil winding degradation and contact oxidation.
- ✓Digital timer or dwell-time function frozen or erratic — HAWO microprocessor clock oscillator failure, capacitor aging in timer circuit, or software EEPROM corruption from power surges. Indian industrial power quality issues (voltage spikes) particularly affect HAWO timer modules.
- ✓Heating element burns out or shows open-circuit resistance — HAWO PTC (Positive Temperature Coefficient) heating strips overheat due to thermostat failure or sustained over-temperature control signal. Thermal cycling and mechanical vibration in packaging lines cause element fracture and insulation breakdown.
- ✓Vacuum pump generates air but seal fails or leaks prematurely — HAWO vacuum valve membrane rupture, seal bar contact degradation, or pressure sensor drift in the vacuum circuit. Particulate contamination from packaged materials damages membrane and sealing surfaces.
- ✓Control PCB relay chatters or contactor fails to release — HAWO relay coil demagnetization, corroded contact armature, or mechanical binding in contactor linkage. High-frequency vibration in industrial packaging lines causes solder-joint fatigue and contact spring relaxation.

Frequently Asked Questions — HAWO Repairs
Do you repair HAWO sealing machines at your Vadodara facility or on-site?+
Both. Synchronics offers on-site troubleshooting and quick-swap component replacement at your manufacturing plant to minimize downtime. For complex HAWO control board repairs, thermostat recalibration, or complete sealer overhaul, we provide express courier service across India—pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad—with repair turnaround of 5-7 working days. All HAWO equipment is tested and sealed before return shipment.
What is the typical cost and turnaround time for HAWO heating element or solenoid repair?+
HAWO heating element replacement costs INR 3,500-7,000 depending on wattage and bar length; turnaround is 3-4 days. Solenoid valve assembly replacement or repair ranges INR 2,500-5,500 with 2-3 day turnaround. Synchronics stocks common HAWO spare parts (heating strips, solenoids, seals, relays) at our Vadodara centre. Rush repairs available for an additional service charge. All repairs include 6-month workmanship warranty.
How do I know if my HAWO thermostat needs recalibration or replacement?+
If your HAWO impulse sealer or band sealer produces inconsistent seal quality—weak seals on one end or cold seals intermittently—the thermostat is likely drifted. Synchronics uses precision digital thermometers and temperature profilers to measure actual sealing chamber temperature against your HAWO machine setpoint. If drift exceeds ±10°C, recalibration restores accuracy. If sensor resistance or winding continuity fails, replacement is required. We provide a sealed calibration report with every HAWO thermostat service.
Can Synchronics repair HAWO control boards with burnt-out traces or failed microprocessors?+
Yes. Our electronics repair specialists can restore HAWO control PCBs with burnt traces via re-routing and jumper wire installation, replace failed microprocessor chips via desoldering and micro-BGA rework, and reload firmware from backed-up EEPROM data. We test repaired HAWO boards on our equipment simulator bench before dispatch. If traces or silkscreen damage is severe, we source original HAWO replacement boards and flash your machine-specific firmware at no additional cost.
Does Synchronics stock original HAWO spare parts or do you use third-party components?+
Synchronics sources original HAWO heating elements, solenoid coils, seal bars, and control relay modules from authorized German suppliers to maintain specification compliance. For common items (capacitors, diodes, transformers, connectors), we use OEM-equivalent industrial-grade components rated for the same voltage, current, and temperature. All replacements are tested to HAWO factory standards before installation. We provide a certificate of origin with major component replacements so you can verify authenticity.
How do I send my HAWO 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 HAWO 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 HAWO 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 HAWO 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.
