FAQ
Q1: Is this machine specially optimized for contactor coils only?
A: It is optimized for mass production of contactor coils, meanwhile compatible with relay coils, solenoid valve coils and magnetic switch coils. You can switch different fixtures to produce various electromagnetic coils on one device.
Q2: How accurate is the winding turn count for contactor coils?
A: Equipped with high-precision encoder counting + PLC closed-loop control, the turn error is strictly controlled within ±0.1 turn, ensuring every contactor coil maintains consistent electromagnetic attraction and stable product quality.
Q3: Can the equipment run continuously for 24 hours in factory production?
A: Thickened carbon steel anti-vibration frame plus industrial-grade PLC and servo parts support non-stop 24-hour continuous operation. It has overload, wire break, overheat protection functions to avoid unexpected shutdowns during mass production.
Q4: How much time is needed to replace molds for different types of contactor coils?
A: Quick-release fixture structure is adopted. Replacing the mold and calling the saved winding program only takes 6–10 minutes, greatly cutting production changeover time for factories with multiple contactor specifications.
Q5: What enamel wire diameter range can this contactor coil winder handle?
A: Standard version supports 0.05mm ~ 2.0mm enameled wire, fully covering most AC/DC contactor coils, relay coils and solenoid coils used in low-voltage electrical appliances. Wire range expansion customization is available upon request.
Q6: Can new employees master operation quickly without professional electrical knowledge?
A: The touchscreen adopts graphical operation interface, all parameters can be set visually. General workers can complete independent operation after 20 minutes of training, no PLC programming experience is required.
Q7: Does the closed-loop tension system effectively solve wire break problems during winding?
A: Real-time tension feedback adjustment avoids wire stretching, scratching or snapping especially when winding fine wires. The wire break rate is greatly reduced compared with ordinary tension structures, lowering defective coil rate.
Q8: Can you customize multi-station structure to boost output of contactor coils?
A: Yes. Based on customer daily output requirements, we can upgrade to double-station or four-station simultaneous winding structure to double production capacity while keeping original winding precision unchanged.
Q9: What after-sales support will be provided after purchasing the winding machine?
A: We supply on-site installation & commissioning, free worker operation training, 7×24 hours remote technical support, and global supply of modular spare parts to minimize maintenance downtime.
Q10: Can the machine power supply voltage be customized for overseas factories?
A: Standard voltage is AC220V / 380V, and we can customize 415V three-phase voltage for European factories, 220V single-phase version for Southeast Asian factories to match local power grid standards.
Q11: Do you offer free winding testing before customers place orders?
A: Free sample winding service is available. Customers can send coil bobbins, wire samples or coil technical drawings, we will complete winding test in our factory and send finished coils plus operation video for confirmation.
Q12: How can I obtain the official quotation and complete equipment catalog?
A: Send your contactor coil specifications, wire diameter and daily production capacity demand via WhatsApp or windingpro.com official website, our technical sales team will send factory price list and catalog within one working day.
