ARBURG Equipment We Repair — By Category
ARBURG Product Lines We Repair
Our engineers are trained on the full ARBURG product range. Below are the major product families we service.
SELOGICA Control System
ARBURG's modular PLC-based control platform managing injection parameters, mold switching, and cycle timing. Common faults: encoder signal loss during mold change cycles, proportional valve driver failures causing pressure instability, and PROFIBUS communication dropout with peripheral devices like robot arms.
UNILOG Automation Controller
Legacy but widely installed ARBURG controller managing pressure compensation, temperature feedback loops, and hydraulic sequencing. Repair issues include analog signal conditioning module failures, battery-backed memory corruption, and relay output card burnout from solenoid valve coil spikes.
MULTILIFT Robot Integration Interface
Electronic handshake and I/O expansion module synchronizing external robotic part removal and placing with ARBURG injection cycles. Common faults: optical isolation chip failure causing signal dropout, connector pin corrosion in humid molding shop environments, and firmware sync errors when upgrading ARBURG software versions.
Proportional Valve Driver Cards
Dedicated amplifier modules controlling spool position in ARBURG hydraulic servo valves via analog command signals. Failures include transistor short-circuit from voltage transients, load-holding capacitor dry-out causing sluggish response, and thermal runaway during continuous high-pressure molding cycles.
Temperature Control Interface
Precision analog input conditioning and relay output module managing barrel, mold, and hydraulic oil temperature setpoints via thermocouple or RTD feedback. Issues: thermocouple amplifier IC failure, relay contact welding under repetitive on-off cycling, and ground loop hum affecting sensor accuracy.
Power Supply and Safety Modules
24V DC and 5V auxiliary supplies powering control logic and safety circuits; includes emergency stop contactor driver. Faults: capacitor bulging from thermal stress in hot molding environments, transformer winding insulation breakdown, and safety relay failure during E-stop validation cycles.

Common ARBURG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARBURG equipment arriving at our workshop.
- ✓Encoder signal loss during mold opening — ARBURG rotary encoder mounted on the mold carriage shuttle experiences intermittent signal dropout due to connector pin oxidation in humid injection molding facilities, or bearing wear causing signal amplitude decay below PLC threshold. Synchronics identifies whether it's electrical (corrosion, broken trace) or mechanical (sensor gap drift).
- ✓Proportional valve sticks mid-cycle pressure spike — ARBURG proportional servo valve driver transistor fails shorted due to unclipped inductive kickback transient when solenoid valve coil is de-energized. Spike voltage exceeds transistor Vce rating, destroying base-emitter junction and preventing smooth spool modulation. Result: erratic pressure, cycle rejection, machine halts.
- ✓PROFIBUS gateway offline - robots not synchronizing — ARBURG MULTILIFT interface board optical isolation stage fails (typical in humid Tamil Nadu textile-plastic hybrid plants) or firmware becomes corrupted during interrupted power-off, severing token ring communication to external device nodes like robotic arms or part conveyors.
- ✓Temperature setpoint oscillating wildly, overshoot beyond limits — ARBURG temperature control card's thermocouple amplifier IC develops thermal drift or capacitive instability; low-pass filter cutoff shifts upward, causing control loop to hunt. Barrel temperature swings ±15C instead of ±2C, degrading part quality and shortening heater element life.
- ✓Emergency stop relay chatter - won't hold off — ARBURG safety relay module contact wear and arcing from high-current contactor switching, combined with insufficient holding voltage during momentary supply dip. Relay acoustic noise and intermittent E-stop circuit failure creates unplanned machine halts or failed safety audit.
- ✓24V main supply ripple causes erratic cycle timing — ARBURG power supply filter capacitor dries out from 12+ years of thermal cycling in molding shop heat, ESR rises, and output ripple climbs to 2-3V peak-to-peak. Analog voltage threshold comparators in SELOGICA trigger at wrong pressure thresholds, advancing/retarding injection phase unpredictably.

Frequently Asked Questions — ARBURG Repairs
Do you repair ARBURG equipment anywhere in India?+
Yes. Synchronics repairs the full ARBURG product range including SELOGICA controllers, UNILOG legacy systems, MULTILIFT integration modules, proportional valve drivers, and temperature regulation boards. We offer PAN India doorstep pickup from Mumbai, Delhi, Pune, Hyderabad, Chennai, Ahmedabad, Surat, Nagpur, and 50+ other cities. All diagnostics and repairs centralized at our Vadodara, Gujarat facility. Typical turnaround 5-7 working days with same-day return logistics.
How do I know if my ARBURG SELOGICA controller has failed or is it a sensor issue?+
ARBURG SELOGICA microcontroller failures typically show fault codes E101-E110 (analog input range errors), E201-E210 (proportional valve driver shorts), or system hang-up with unresponsive operator panel. Sensor faults show intermittent code flicker or gradual drift. Synchronics performs free bench acceptance test - we power your SELOGICA board in isolation using our industrial test harness, simulate proportional valve load, and check all 24 I/O channels. This definitively separates controller failure from plant-side wiring or sensor issues. Report emailed within 24 hours.
What if my ARBURG machine is old (1998-2008 era UNILOG) - can you still repair it?+
Absolutely. Synchronics specializes in legacy ARBURG UNILOG A/B/C boards that most competitors refuse. We stock equivalent discrete components, custom-rewind transformers, and original relay modules no longer in ARBURG catalogs. Our team reverse-engineers firmware using original 1990s reference documentation. Typical UNILOG repair cost is 40-50% of new board replacement, and we deliver within 8-10 days including component sourcing. We have restored UNILOG systems at major automotive Tier-1 suppliers across Gujarat and Maharashtra.
My ARBURG robot synchronization keeps losing sync - MULTILIFT keeps timing out. What causes this?+
ARBURG MULTILIFT timeout usually stems from optical isolation chip failure (MOC3020 or MOC3021 photodiode failure is common in dusty/humid injection molding shops), firmware corrupted during power glitch, or host SELOGICA PLC losing PROFIBUS token ring timing due to baud rate clock skew. Synchronics tests MULTILIFT optical coupling voltage on the scope, validates PROFIBUS termination resistor presence, and re-flashes firmware from factory media. We then perform full integration test syncing your ARBURG cycle with downstream robot. Typical resolution 3-4 days.
Is your ARBURG repair faster and cheaper than sending it to the nearest ARBURG service center?+
Yes. ARBURG authorized service centers in India often outsource diagnostics abroad or order parts from Germany (6-8 week lead time), inflating repair cost 30-50% and downtime 4-6 weeks. Synchronics holds stock of proportional valve driver ICs, encoder connectors, and control card components. We diagnose same day, repair within 5-7 days, and charge 35-45% less than ARBURG OEM rates for identical repair quality. We are ISO 9001 certified and offer 12-month warranty on all repairs — your ARBURG runs at full precision again.
How do I send my ARBURG 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 ARBURG 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 ARBURG 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 ARBURG 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.
