BOY Product Lines We Repair
Our engineers are trained on the full BOY product range. Below are the major product families we service.
BOY 15M / 25M / 35M Compact Series
Horizontal injection molding machines for small-to-medium part production. Common issues include proportional directional valve solenoid failures, PLC input card malfunctions, and servo motor driver faults affecting clamping pressure stability.
BOY XS / S / M Series (All-Electric Machines)
Energy-efficient all-electric molding systems with integrated servo drives and digital process controllers. Repairs often involve servo amplifier calibration, encoder feedback circuit restoration, and PLC communication module replacement.
BOY Micromaster Control Module
Legacy and modern hydraulic control electronics with proportional solenoid drivers, pressure sensors, and temperature regulation circuits. Typical faults include solenoid coil burnout, pressure transducer signal loss, and thermal runaway in heater control stages.
BOY Hydraulic Proportional Valve Driver Cards
Dedicated power amplifier boards for spool control and directional flow switching. Repair requires precision board-level work: transistor replacement, gate driver IC restoration, and dead-time calibration to ensure consistent clamping and ejection cycles.
BOY Digital Temperature Controller (DTC) Interface
Barrel and nozzle temperature monitoring and regulation with thermocouple or RTD sensor inputs. Common faults: thermocouple sensor break detection, relay contact welding, PID tuning loss, and SSR (Solid State Relay) failure in heating elements.
BOY Machine Vision & Dimensional Inspection Module
Optional integrated quality control cameras and image processing cards for in-mold dimensional checking and defect detection. Repair includes camera sensor restoration, video frame processor recovery, and trigger signal line conditioning.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common BOY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BOY equipment arriving at our workshop.
- ✓Proportional solenoid valve coil burnout — BOY proportional directional solenoids overheat due to continuous energization during mold hold phase, inadequate cooling airflow in the machine enclosure, or voltage spikes from defective PWM driver transistors on the valve control card.
- ✓PLC input card losing pressure sensor signal — BOY analog input modules (4-20mA transducer cards) suffer from capacitor degradation in the signal conditioning stage, cold solder joints on pressure transducer connectors, or electromagnetic interference coupling from adjacent servo drive cables.
- ✓Servo motor encoder feedback loss during production run — BOY all-electric series machines (XS/S/M) experience encoder cable abrasion, connector corrosion, or incremental encoder IC failure. Debris accumulation and vibration cause intermittent signal drop during rapid axis acceleration.
- ✓Temperature controller showing sensor fault and heater disable — BOY DTC modules lose thermocouple continuity due to connector oxidation, cable shield grounding to mold frame, or actual thermocouple bead fracture. Cold junction compensation circuits may also drift if reference IC ages.
- ✓Clamp pressure instability and inconsistent part weight — BOY proportional pilot-operated valves develop internal spool stiction, vent orifice clogging, or feedback LVDT (Linear Variable Differential Transformer) drift. Hydraulic fluid contamination accelerates wear.
- ✓Ejection cylinder malfunction or slow return speed — BOY proportional directional valve spools wear internally, reducing flow capacity. Cartridge-style vent check valves stick open, bypassing pressure. Seal degradation and internal leakage reduce net clamping and ejection force.

Frequently Asked Questions — BOY Repairs
Do you repair BOY injection molding machine electronics across India?+
Yes. Synchronics Electronics repairs the complete BOY control ecosystem—proportional valve drivers, hydraulic controllers, temperature regulation modules, servo amplifiers, and PLC interfaces. We offer PAN India pickup from Vadodara, Gujarat (our manufacturing hub) and service all major industrial cities including Pune, Nashik, Ahmedabad, Surat, Mumbai, Bangalore, Hyderabad, and Chennai. Same-day diagnostics and 5-7 day turnaround on most repairs.
What is the typical cause of BOY proportional solenoid burnout in Indian molding plants?+
In Indian climate conditions—particularly in non-air-conditioned or poorly ventilated molding shops—BOY proportional solenoids overheat due to inadequate enclosure cooling and dust accumulation on driver transistors. High ambient temperature (40-45°C) reduces thermal headroom. Combined with continuous PWM energization during long production runs, coil insulation breaks down. Synchronics installs thermal analysis during repair and recommends enclosure ventilation upgrades to prevent recurrence.
How long does BOY machine control diagnostics and repair typically take?+
Synchronics typically completes initial fault diagnosis (2-4 hours), board-level repair or component replacement (2-3 days), and full functional testing including hot-run validation (1-2 days). Complex multi-module failures or servo system recalibration may extend to 7 days. We maintain stock of common BOY spare boards and proportional valve components to minimize downtime.
Can Synchronics repair BOY legacy DTC (Digital Temperature Controller) modules manufactured before 2010?+
Yes. Synchronics routinely repairs vintage BOY DTC-E and DTC-PRO modules. We stock replacement capacitors, relay contact assemblies, and thermal sensor interface ICs specifically rated for legacy BOY hardware. Firmware and configuration data can often be preserved if EEPROM is undamaged. We recommend migration planning to modern DTC-PRO units for long-term spares availability.
What documentation or part numbers should I provide when sending a BOY machine control card for repair?+
Provide the machine model (e.g., BOY 35M, BOY S 500E), failed board part number or function (e.g., proportional valve driver, input analog card), symptom description, error codes or fault history, and machine serial number if available. Photos of connector pinouts and any visible damage help. Synchronics can reverse-engineer unlabeled modules via thermal imaging and circuit tracing if documentation is unavailable.
How do I send my BOY 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 BOY 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 BOY 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 BOY 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.
