Frequently Asked Questions

FAQ

Quick Answers for Your Decision
We manufacture motor casings and pulleys in a wide range of materials to match your application needs: aluminum alloy (ADC12, A380), cast iron (HT250, QT500), and stainless steel (304, 316). For special requirements, we also offer brass and alloy steel options. Material selection is guided by factors like heat dissipation, corrosion resistance, weight, and cost — our engineering team will recommend the optimal grade for your specific usage.
Our standard MOQ for custom-made pulleys and impellers is 500 pieces for first production runs. However, we fully support sample orders (as low as 5–10 pieces) for qualification testing and prototyping. For high-volume production orders (10,000+ units), we offer competitive volume discounts and priority lead times. Please contact us with your drawings — we'll provide a tailored quotation.
We are IATF 16949 and ISO 9001 certified, with a comprehensive in-house quality control system. Every batch undergoes:
  • Dimensional inspection – using CMM (Coordinate Measuring Machines) with ±0.01mm accuracy.
  • Dynamic balancing – meeting G6.3 or higher standard to minimize vibration.
  • Material composition analysis – via spectrometer to verify alloy grades.
  • Hardness and tensile testing – to guarantee mechanical properties.
We provide full traceability from raw material to finished part, and every shipment includes inspection reports upon request.
Yes – we are a dedicated OEM/ODM manufacturer. We accept 2D drawings (PDF, DWG) and 3D models (STEP, IGES, SolidWorks). Our engineering team reviews each design for manufacturability and suggests cost-saving optimizations without compromising quality. We also offer reverse engineering services if you have sample parts but no formal drawings. Just send your requirements, and we'll handle the rest.
For custom orders, our average lead time is 15–25 days after drawing approval and material preparation. For standard stock items, we can ship within 7–10 days. We work with reliable freight forwarders and offer flexible shipping options: FOB Ningbo/Shanghai, CIF, or DDP (door-to-door) based on your preference. Expedited shipping is available for urgent requirements.
