DESMA Product Lines We Repair
Our engineers are trained on the full DESMA product range. Below are the major product families we service.
DESMA Hydraulic Control Systems
Closed-loop proportional valve controllers, pressure regulators, and flow management boards for injection moulding machines. Common failures include solenoid coil burnout, pressure transducer drift, and valve spool stiction causing inconsistent shot pressure and part defects.
DESMA PLC and Logic Controllers
Programmable logic modules for mould cycle control, ejector timing, and multi-station automation. Faults include firmware corruption, digital input card failure, relay module burnout, and communication bus errors between control nodes.
DESMA Temperature and Process Monitoring
RTD and thermocouple input modules, temperature controller boards, and process data acquisition units. Typical failures are sensor input card failures, ADC module degradation, and calibration drift causing temperature control instability.
DESMA Motor Drive and Power Electronics
DC servo drives, AC induction motor controllers, and power supply modules for injection drive and clamping motors. Common issues include IGBT failure, gate driver burnout, rectifier diode failure, and capacitor drying causing motor stalling and phase loss.
DESMA HMI and Operator Interface Boards
Touchscreen control boards, keypad interface modules, and industrial display drivers for machine operation and diagnostics. Failures include LCD controller chip burnout, capacitive touch sensor failure, communication port degradation, and firmware boot errors.
DESMA Communication and Networking Modules
Profibus, Ethernet gateway cards, and serial communication interfaces for machine-to-PLC-to-host integration. Typical faults are transceiver chip failure, isolation transformer burnout, protocol firmware issues, and connector corrosion on industrial networks.

Common DESMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DESMA equipment arriving at our workshop.
- ✓DESMA solenoid directional valve coil burnout — Prolonged solenoid energization, voltage spikes from inductive switching, or moisture ingress into coil winding causes insulation breakdown and open circuit. Symptom: proportional valve does not respond to control signals, mould remains open or injection pressure drops.
- ✓DESMA PLC firmware corruption and boot failure — Power loss during PLC firmware upload, corrupted EEPROM sector, or watchdog timer reset during operation causes loss of mould sequence logic and machine halt. Symptom: PLC LED shows error state, no response to start button, loss of ejector timing.
- ✓DESMA temperature sensor input card ADC failure — RTD or thermocouple input module analog-to-digital converter chip damaged by EMI, overvoltage transient, or prolonged thermal stress causes temperature reading drift or complete signal loss. Symptom: erratic temperature display, machine goes into overheat shutdown, or heater remains off.
- ✓DESMA servo motor drive IGBT short circuit — Gate driver failure, control signal noise, or junction temperature overstress in injection or clamping servo motor IGBT causes shoot-through short and main fuse rupture. Symptom: loss of motor power, audible circuit breaker trip, no injection or clamp force.
- ✓DESMA proportional valve pressure transducer drift — Sensor diaphragm deformation, adhesion buildup in hydraulic pressure port, or conditioning amplifier IC aging causes slow offset shift in 4-20mA feedback loop. Symptom: actual shot pressure differs from display, moulded parts show size variation, machine displays pressure fault code.
- ✓DESMA HMI touchscreen controller communication loss — Loose or corroded Profibus or RS-485 connector, failed isolation transformer on communication module, or serial protocol timeout in firmware causes HMI display freeze and loss of operator feedback. Symptom: blank screen, no response to touch input, machine cannot receive commands.

Frequently Asked Questions — DESMA Repairs
Do you repair DESMA equipment anywhere in India?+
Yes. Synchronics repairs the full DESMA electronics range - hydraulic control boards, PLC modules, motor drives, temperature controllers, HMI interfaces, and communication gateways. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are done at our factory facility in Vadodara, Gujarat with 48-72 hour standard turnaround on most DESMA control board faults.
What is included in a DESMA control board repair from Synchronics?+
We perform full functional diagnosis using DESMA-compatible test benches, identify failed components (capacitors, ICs, connectors), replace with genuine quality parts, reprogram machine parameters if needed, and run complete cycle testing before return. You receive a detailed fault report, parts replacement certificate, and 12-month warranty on all repairs.
Can you repair DESMA injection moulding machine faults like erratic pressure or ejector timing?+
Yes. Most DESMA machine faults originate in control electronics - proportional valve boards, PLC logic modules, or sensor input cards. Synchronics troubleshoots root causes using oscilloscope and diagnostic software, repairs or replaces faulty control boards, recalibrates pressure loops and timing sequences, and delivers machines back with verified moulding consistency and cycle time.
Do you provide on-site support for DESMA machines in Indian plants?+
Yes. Our field service team provides emergency on-site diagnostics and board swaps at your plant location in major industrial cities. We keep common DESMA replacement boards (servo drives, PLC modules, proportional controllers) in stock for immediate deployment. Contact our support hotline for same-day or next-day on-site assistance across India.
What if DESMA spare parts are unavailable - can you provide equivalent boards?+
Synchronics always uses genuine DESMA components or OEM-equivalent parts tested for full compatibility with your machine architecture. If original parts are obsolete, we provide alternative control board solutions from approved industrial suppliers, reprogram them with your machine parameters, and provide extended warranty. We maintain parts relationships with DESMA dealers across Europe and India for fast supply.
How do I send my DESMA 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 DESMA 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 DESMA 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 DESMA 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.
