Customize FAQ

  • Can DADESIN make design drawings?

    We provide suggestions to improve drawings, but do not provide design service. We accept 3D CAD files in STL, STEP or IGES format, 2D drawings with reference dimensions in AI/CAD/PDF/JPG format. We must receive complete manufacturing information as part of this technical documentation.

  • Is DADESIN a real factory?

    YES, DADESIN established since 2006, we now have production sites with a total area of more than 86,000 square feet. Welcome to visit us, we will pick up you at the airport or from your hotel.

  • Will my designs be kept confidential?

    DADESIN has a strict confidentiality system and confidentiality software, all the drawings cannot be opened by anyone without authorization; NDA can be signed to ensure the safety of your designs.

  • How can you guarantee the delivery time?

    DADESIN owns 200+ sets of processing machines and 150+ skillful staff to ensure your order on schedule.

  • How does Star Rapid ensure the quality of my parts?

    --Once your order is confirmed, we will perform a full Design for Manufacturing (DFM) review to point out any issues that our engineers feel may affect the quality of your parts.
    --All incoming materials are inspected and verified with a suite of testing equipment.
    --Final inspection reports before shipment.
    --We have the ability to share inspection data with you in real-time so we can work together to address any quality issues you may have during production.

Representative Customer Case Display

EV Motor Housing

  • Services:CNC milling, polishing
  • Material:Aluminum 6061
  • Quantity:20

The Product

The motor housing is a critical component of the electric vehicle. It must be strong enough to withstand the high torque and heat generated by the motor, while still being lightweight enough to not add too much to the overall weight of the vehicle.

Material Inspection

As we do with all of our projects, we double-checked that the incoming raw material marked as “AL 6061” was exactly that.

CNC Milling

This part was machined from aluminum alloy 7075 using 5-axis CNC milling. The part was designed as a form prototype, which allowed us to quickly iterate on styling, fit and function. We then used our extensive experience with low volume production runs in order to optimize tooling and make sure each part would be as cost-effective as possible for our client.
