Frequently Asked Questions

From sourcing premium raw materials to the final inspection, we ensure every detail meets our high standards before it reaches you.

How do we ensure my design is ready for reliable manufacturing?

Upload your CAD files for instant, automated DFM feedback on geometry and tolerances. For complex projects, our engineers provide a detailed manual review within 24 hours, offering actionable insights on materials and design to ensure a flawless production run.

Hanstar are certified to ISO9001, IATF16949, AS9100D, and ISO13485, ensuring our quality management system meets international standards across industrial, automotive, aerospace, and medical sectors.

We provide instant online quotes for standard manufacturing services. Simply upload your 2D or 3D files and select your preferred process, material, finish, and quantity. If your project is more complex, a dedicated engineer will reach out within one business day to review your requirements and prepare a customized proposal.

We accommodate design changes whenever possible. Minor adjustments during prototyping are typically seamless, while changes during mass production may impact costs and lead times. Our team will provide a full impact assessment to ensure minimal disruption.

For prototyping and low-volume orders, we offer no MOQ so you can order as few as one part. For injection molding and large-scale production, MOQ depends on the tooling and process—our team will provide a detailed breakdown during quoting.
