COATINVEST Product Lines We Repair
Our engineers are trained on the full COATINVEST product range. Below are the major product families we service.
COATINVEST Thermal Spray Control Units
Programmable controllers managing plasma torch ignition, gas flow rates, substrate temperature, and spray pattern sequencing. Common issues include thermocouple sensor faults, relay board failures, and heating element burnout under high-cycle thermal stress.
COATINVEST Vacuum Pump Controllers
Drive and monitor systems for rotary vane and turbomolecular pumps in PVD/CVD chambers. Failures include soft-start capacitor degradation, motor contactor arcing, and pressure transducer signal loss from thermal shock.
COATINVEST Power Supply Modules
High-frequency rectifier and DC distribution units delivering 5-50 kW to plasma torches and heating elements. Repair focuses on bridge rectifier failures, filter capacitor aging, and output regulation circuit drift under thermal load.
COATINVEST Process Gas Regulation Systems
Precision mass flow controllers and proportional solenoid valve drivers for Ar, N2, and reactive gas blending. Common faults include valve spool stiction, signal conditioning board noise, and mass flow sensor calibration drift.
COATINVEST Temperature Management Systems
Multi-zone resistance heater drivers with real-time feedback from RTD and thermocouple networks. Failures stem from heating element open-circuit, thermowell corrosion, and PID loop instability causing thermal cycling.
COATINVEST Torch Position Feedback Modules
Encoder and resolver interface cards for XY scanning and standoff distance maintenance in automated spray heads. Typical issues include resolver cable shielding damage, encoder counter overflow, and servo loop gain instability.

Common COATINVEST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COATINVEST equipment arriving at our workshop.
- ✓Plasma torch ignition failure on cold start — COATINVEST torches require precise high-voltage strike sequencing (typically 8-12 kV pulse). Failures occur when ignition transformer secondary windings short due to ceramic insulator micro-cracking under thermal cycling, or when gate-drive circuits in the plasma control board lose timing synchronization.
- ✓Spray pattern asymmetry or torch dropout mid-cycle — COATINVEST plasma stability depends on constant substrate temperature and precise gas flow ratios. Asymmetry occurs when thermocouple signal is intermittent (connector corrosion or ceramic sheath micro-cracks), or when proportional valve response becomes sluggish due to solenoid coil insulation breakdown or spool friction.
- ✓Vacuum chamber pressure rise or pump slow-down — COATINVEST vacuum systems rely on motor soft-start circuits to protect pump bearings. Pressure creep indicates failing vacuum pump capacitor (ESR drift), motor contactor chatter, or pump shaft seal wear. Thermal overload can trigger nuisance shutdowns if the VPC controller's current-sense transformer saturates.
- ✓Temperature overshoot or hunting in multi-zone heater control — COATINVEST TMS systems use cascaded RTD loops with proportional-integral-derivative (PID) tuning. Overshoot and oscillation occur when PID gain constants drift due to analog op-amp aging, when RTD lead resistance changes from thermal expansion, or when heater element resistance increases with scale buildup.
- ✓Torch positioning servo lag or axis runaway — COATINVEST robotic spray heads use resolver feedback for closed-loop XY motion. Servo lag occurs when resolver-to-digital converter resolution degrades (internal capacitor leakage), when encoder cable shields are compromised (EMI ingress from adjacent RF sources in PVD chambers), or when servo amplifier output stage transistor pairs lose matched gain.
- ✓Power supply output voltage regulation drift or ripple increase — COATINVEST PSM modules use bridge rectifiers and LC filtering to deliver stable 1500-2000 VDC to plasma torch electrodes. Regulation drift occurs when feedback potentiometer wiper resistance increases (corrosion), when filter capacitors age and lose capacitance (especially in high-ambient cabinet temperatures near 60°C), or when output transformer has inter-winding short turns.
