Engineering Inquiry

Request an EMI Shielding Quote

Send Ruishuo your EMI shield structure, drawing revision, material, quantity and validation requirements. Request a quote or discuss a manufacturing review.

Tell us about the part and the project stage

Describe the structure, material, quantities and the engineering question you need resolved. An undecided requirement can be marked for review—for example, a single-body shield versus a removable lid, or a choice of material and finish.

Submit the project brief using this form. Send drawings separately to chinarswj@shieldingcover.com, using the same company, project or part reference so the files can be matched to your inquiry. For confidential designs, discuss the NDA and information scope first.

Send your project requirements

Email drawings separately using the same project reference. Files are not uploaded through this form.

Samples are charged: standard samples 3–5 days; expedited sampling 48 hours; tooling and sample production 7–10 days. Volume production and delivery are reviewed separately.

By submitting, you agree that Ruishuo may use these details to respond to your project inquiry. Read our inquiry privacy information.
