Reduce supplier count from 3 to 1. | | **Self-Locking by Design** | Worm gear mechanism inherently holds position without power. Fail-safe by physics, not software. | | **Automotive-Grade Quality** | IATF 16949 certified production. PPAP/APQP documentation available for automotive programs. | | **Fast Prototyping** | Custom actuator samples in 1-2 weeks. CAD models in 24 hours. | | **20-Year Factory** | Established manufacturing with consistent quality across production years. Your multi-year program is safe. | | **Cost Advantage** | Complete actuator assembly at $12 FOB vs. $15-25 from competitors. 30-60% below Western suppliers. | --- ## Frequently Asked Questions **Q: Can you provide a complete actuator assembly, not just the motor?** A: Yes. Our ASM-01 assembly includes N20 worm motor + IP67 micro switch + housing + automotive connector, 100% tested, at $12.00 FOB (1K+). This is our recommended solution — one supplier, one quality system. **Q: Does the worm gear really stay locked without power?** A: Yes. The worm gear geometry provides inherent self-locking — the output gear cannot back-drive the worm. This is a mechanical property, not dependent on electronics, making it ideal for safety-critical charging applications. **Q: What automotive documentation do you provide?** A: For IATF 16949 programs, we provide PPAP Level 3 documentation, including: dimensional reports, material certifications, process FMEA, control plan, capability studies (Cpk), and IMDS data. **Q: Can you customize the locking travel distance?** A: Yes. We customize the output shaft, cam profile, and limit switch position to match your required locking travel. Standard configurations support 5-15mm linear travel. **Q: What about EMI/EMC compliance?** A: DC brushed motors generate electrical noise. We offer ferrite-suppressed configurations for sensitive applications. For ultra-low EMI, we recommend our BLDC-based actuator options. **Q: What's the lead time for production orders?** A: Standard configurations: 2-3 weeks for 1K units. Custom assemblies: 4-6 weeks for first production run. We maintain safety stock for repeat customers. **Q: Do you support the Chinese GB/T market?** A: Yes. Our factory is in China and our actuators are fully compliant with GB/T 20234.1/.2/.3 standards. We supply motors to several Chinese EV charger manufacturers. --- ## Ready to Power Your Charging Gun?
