FRECH Product Lines We Repair
Our engineers are trained on the full FRECH product range. Below are the major product families we service.
FRECH SPEEDLINE Series
High-speed cold-chamber die-casting machines (8–15 shots/minute) designed for high-volume automotive aluminum casting. Common repair issues include servo valve electronics failures, pressure transducer drift, shot-end timing circuit faults, and PLC watchdog resets under high-cycle stress.
FRECH Magnecast Series
Hot-chamber die-casting machines optimized for magnesium and zinc alloys. Common faults include temperature control instability, plunger-position feedback sensor degradation, holding-pressure regulation drift, and alloy-specific corrosion of electrode contact assemblies.
FRECH Smart Control Platform
Integrated PLC, HMI, and motion controller for FRECH machine suites. Handles clamp sequencing, injection timing, ejector synchronization, and cycle monitoring. Repair needs include encoder signal loss, stepper motor driver burnout, Profibus/Profinet communication faults, and firmware recovery.
FRECH Hydraulic Servo Units
Precision proportional valve controllers and pressure-regulation modules for shot-intensity, clamp-force, and ejector-speed management. Frequent failures: spool-position LVDT sensor wear, solenoid coil burnout under pulsed duty, pressure feedback loop instability, and proportional spool stiction.
FRECH Mold Temperature Control (MTC) Systems
Closed-loop heater and cooler regulation for mold cavity temperature stability (critical for surface finish and cycle repeatability). Common repair issues: thermostat relay chatter, proportional valve drift, temperature probe connection intermittency, and oil-cooler fan motor failure.
FRECH Ejector & Clamping Electronics
Dedicated control modules for ejector stroke timing, clamping sequence synchronization, and mold safety interlocks. Faults include position encoder failure, logic relay degradation, safety loop timeout errors, and mold-open sensor intermittency.

Common FRECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FRECH equipment arriving at our workshop.
- ✓FRECH shot-end pressure control drift — Proportional valve spool stiction combined with pressure transducer calibration drift (0.5–2% per year in high-cycle environments). Magnesium machines are especially prone due to alloy reactivity and moisture ingress in sensor connectors.
- ✓FRECH PLC watchdog reset and cycle interruption — Electrical noise from high-inrush clamping solenoids coupling into PLC input modules, or slow program scan time due to aged PLC scan interrupt handling. Common in older FRECH SmartControl CP-500 units with marginal power supply filtering.
- ✓FRECH ejector position encoder signal loss (encoder error E-104 or similar) — Intermittent connector corrosion at mold ejector sensor plug, or magnetic-disc encoder gap creep due to vibration and thermal cycling. Ejector motion feedback is critical for safe mold-open and part-ejection timing.
- ✓FRECH mold temperature control oscillation (overshoot/undershoot) — Proportional valve gain tuning drift, or stuck thermostatic valve creating on-off hysteresis in heater/cooler circuits. MTC system integral gain constants decay over months in high-heat foundry environments.
- ✓FRECH servo hydraulic line pressure spikes (>250 bar transient surges) — Proportional pump unload solenoid stickiness or check-valve leakage in shot-intensity circuits, allowing pressure rise during rapid clamp acceleration. Magnecast series with magnesium alloys are prone to check-valve contamination from alloy grit.
- ✓FRECH Profibus/Profinet communication timeout (error 224 or 'Node offline') — Aged Profibus terminator resistor failure (120 Ω resistors in junction boxes deteriorate in heat and humidity), or loose shield grounding at PLC or remote I/O modules. Network scanning halts, freezing die-casting cycle.

Frequently Asked Questions — FRECH Repairs
Do you repair FRECH die-casting machine control systems anywhere in India?+
Yes, absolutely. Synchronics provides door-to-door pickup and repair for FRECH control electronics, servo hydraulic units, PLC modules, and mold-temperature systems from all major Indian industrial hubs — Mumbai, Pune, Bangalore, Chennai, Hyderabad, Nashik, Aurangabad, Ahmedabad, Rajkot, Surat, and across Gujarat and Maharashtra. Your machine ships to our factory in Vadodara, is diagnosed, repaired, tested under load, and returned within 7–14 days. We maintain OEM-spec spare parts and programming tools for FRECH SmartControl platforms.
What is the typical turnaround time for FRECH machine electronics repair at Synchronics?+
Standard turnaround is 7–10 working days for diagnosis, component repair, calibration, and full-cycle testing. Emergency repairs (pressure control, encoder faults, clamp timing issues) can often be completed in 3–4 days if parts are in stock. Hydraulic servo-unit overhauls (valve reseating, spool replacement, solenoid coil rewinding) take 5–7 days. Synchronics provides daily updates via email/WhatsApp, and we can expedite shipment back to your facility — cost depends on location and urgency.
Can you repair FRECH servo proportional valves and pressure transducers?+
Yes — Synchronics has in-house facilities for FRECH proportional valve spool cleaning, seal kit replacement, solenoid coil testing and rewinding, and pressure transducer calibration and range adjustment. We hold stock of FRECH OEM valve cartridges (HSU series) and sensor assemblies. All repairs are tested on precision benches before return. We also offer predictive maintenance — pressure waveform analysis, encoder gap verification, and seal-kit life budgeting — to help Indian foundries and automotive suppliers extend machine uptime.
Does Synchronics offer FRECH machine modernization or firmware upgrades?+
Yes. We can upgrade older FRECH SmartControl CP-500 and CP-700 units with faster PLC scan modules, modern Profinet/Ethernet gateway cards, improved EMI filtering, and firmware patches. We also retrofit inductive proximity sensors, digital temperature controllers, and networked IoT monitoring adapters to enable remote cycle tracking and predictive fault alerts. Modernization is especially valuable for high-volume automotive suppliers looking to reduce scrap and cycle-time variability — a common pain point in Indian die-casting operations with tight OEM tolerances.
What documentation or spare parts should I keep for my FRECH machine?+
Keep your FRECH machine wiring diagram (typically a laminated A3 schematic), pressure/temperature calibration charts, proportional valve response curves, and PLC program backup (on USB). For spare parts, Synchronics recommends stocking: (1) pressure transducer cartridges, (2) proportional solenoid coils (HSU units), (3) servo-valve seal kits, (4) encoder assemblies for ejector feedback, (5) Profibus terminators (120 Ω), and (6) PLC memory backup battery. Contact us for a part-number list specific to your FRECH model — we can also arrange annual preventive maintenance audits to catch drift early and avoid unplanned shutdowns during peak production.
How do I send my FRECH 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 FRECH 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 FRECH 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 FRECH 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.
