Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for mass production?
A: For standard sizes, lead time is 4–6 weeks after order confirmation. Custom designs may require 6–8 weeks for tooling and sampling. -
Q: Can the rotor be used in high-temperature applications?
A: Yes, the PA/PPS material withstands continuous operation up to 150°C, with short-term peaks up to 180°C. -
Q: Do you provide samples for testing?
A: Yes, we offer sample pieces upon request. A nominal fee may apply, which is refundable with bulk orders. -
Q: What magnetic strength options are available?
A: We can supply NdFeB magnets from grade N35 to N52 (or equivalent). The rotor’s magnetic field can be customized to your required Gauss or Br value. -
Q: Is the rotor compatible with automated assembly systems?
A: Absolutely. The ±0.02mm tolerance ensures precise fit in pick-and-place robots and press-fit operations. -
Q: How do you ensure the ±0.02mm tolerance during mass production?
A: We use precision mold inserts with hardness HRC58-62, combined with automated injection molding machines and in-line dimensional measurement via laser sensors. SPC data is collected for every batch. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ for standard rotors is 5,000 pieces. For custom designs, MOQ may be 10,000 pieces depending on tooling complexity. -
Q: Do you offer packaging options for export?
A: Yes, we provide anti-static, shock-proof packaging suitable for sea or air freight. Custom labeling and barcoding are available.
