Product Description
The Continuous Automatic Immersion Machine represents the state of the art in motor winding insulation treatment. Unlike traditional manual dipping methods that produce inconsistent results and high labor dependency, this fully automated system carries workpieces through six precisely controlled stages — pre-heating, varnish immersion, draining, gelling, curing, and final cooling — all on a single continuous conveyor. The result is uniformly impregnated stator windings with superior dielectric strength, mechanical integrity, and thermal conductivity.
At the core of the machine is its PID-controlled thermal management system, which maintains each process zone at the exact temperature required for optimal varnish penetration and curing. Temperature accuracy of ±2°C ensures that every stator — whether it is a 40 mm OD micro-motor or a 200 mm OD industrial unit — receives identical treatment. The PLC control system stores up to 50 recipe presets, allowing operators to switch between product families with a single touch. The immersion depth, dwell time, conveyor speed, and curing profile are all independently programmable, giving manufacturing engineers complete control over the insulation process.

Key Selling Points
1. Six-Stage Continuous Process The machine integrates pre-heating, immersion, draining, gelling, curing, and cooling into one uninterrupted flow. Pre-heating removes moisture from windings and opens capillary structures, allowing varnish to penetrate deeper. The controlled gelling stage prevents varnish runoff before curing, while the final cooling zone brings workpieces to a safe handling temperature. This comprehensive process eliminates the need for multiple separate machines and manual transfers.
2. Precision Thermal Control Each of the six process zones features independent PID temperature controllers with ±2°C accuracy. Ceramic fiber insulation minimizes heat loss, and forced-air circulation ensures uniform temperature distribution throughout the curing chamber. This level of thermal precision prevents under-cured windings (which cause premature insulation failure) and over-cured windings (which become brittle and crack under vibration).
3. Closed-Loop Varnish Management The varnish tank is equipped with automatic level control, viscosity monitoring, and temperature stabilization. A recirculation filtration system removes contaminants and prevents skin formation, extending varnish service life by up to 40% compared to open tanks. The machine automatically tops up varnish when levels drop and alerts operators when viscosity deviates from the programmed range.
Quality Control & Certification
Every Continuous Automatic Immersion Machine undergoes rigorous testing before shipment. We run a 72-hour continuous production trial using customer-specified stator samples and varnish, verifying temperature uniformity across all zones, conveyor positioning accuracy, varnish consumption rate, and finished winding insulation resistance. Each machine ships with a factory test report, calibration certificate, and CE declaration of conformity. Our manufacturing facility is ISO 9001:2015 certified, and all electrical components comply with IEC standards.
Operation & Maintenance
Daily Maintenance:
- Check varnish level and viscosity at start of shift
- Clean drip trays and remove any cured varnish residue
- Verify all zone temperatures reach setpoints within 15 minutes
- Inspect conveyor chain tension and lubrication
Weekly Maintenance:
- Clean or replace air intake filters on curing zone blowers
- Calibrate temperature sensors using reference thermometer
- Inspect and clean varnish recirculation filter
- Verify emergency stop and safety interlock functions
Periodic Maintenance (Every 3 Months):
- Replace varnish tank liner and perform full tank cleaning
- Inspect heating elements for corrosion or damage
- Lubricate conveyor drive gearbox and bearings
- Full system calibration by certified technician

Pre-Sales & After-Sales Service
Pre-Sales: Our process engineers work closely with you to analyze your stator specifications, varnish type, target output, and factory layout. We provide detailed process flow diagrams, energy consumption estimates, and ROI calculations. Free sample processing is available — send us your stators and varnish, and we will run trials on our demo machine and return treated samples with a full insulation test report.
After-Sales: Every machine includes a 12-month comprehensive warranty. We provide on-site installation, commissioning, and operator training (5–7 working days) by certified technicians. 24/7 remote technical support is available via video call, with guaranteed 4-hour response for urgent issues. Spare parts are stocked in our warehouse and dispatched within 48 hours via DHL/FedEx. Annual maintenance contracts are available for customers requiring maximum uptime.
FAQ
Q: Can the machine handle both solvent-based and water-based varnishes? A: Yes, the thermal profiles and ventilation systems are configurable for both varnish types. Water-based varnishes typically require slightly longer curing times, which is easily accommodated by adjusting conveyor speed.
Q: What is the minimum order quantity? A: Our MOQ is 1 set. Package discounts are available for customers purchasing complete motor production lines.
Q: How long is the delivery time? A: Standard configurations ship within 30–40 working days. Custom-designed lines for larger stators or special processes may require 50–60 working days.
Q: Do you provide installation support overseas? A: Yes, we dispatch technicians to your facility for installation, commissioning, and training. Travel and accommodation costs are quoted separately.
