AI-Powered supplier vetting

SummarySuzhou Engin Medical Technology Co., Ltd. is identified as a trading company and limited company with five employees, no affiliated group, and a valid import/export license. It offers microscope accessories and aspheric lenses, with ISO 9001 and GMP management-system certifications, five production lines, and stated output and staffing data. The supplier supports flexible, minor, full, design-based, and sample-based customization, but reports no new products during the past year, no ODM service, and no SDK. Service lead times are within 15 working days in both peak and off-seasons. Overseas support is limited: no overseas agents, branches, warehouse, showroom, or stated overseas-service countries. Service governance is weakly documented, with no written supplier-service assessment or corrective/preventive-action procedures. Financial records are indicated for 2022–2024, but no financial results are provided. No customer cases or named brand OEM experience are evidenced.

Supplier typeThe supplier is explicitly classified as a trading company and a limited company, with five employees and no affiliated company group. Its stated scope includes licensed goods and technology import/export activities, and it holds a valid import/export license.

CertificationsThe supplier reports ISO 9001 and GMP certifications, providing explicit evidence of recognized quality and manufacturing-management systems. The slices do not provide certificate numbers, scope, or validity dates, so the assessment is limited to the stated certifications.

After-Sales capabilityLead times are stated as within 15 working days in both peak and off-season, and acceptable service quotation/payment terms are specified. However, the supplier has no in-stock capacity, overseas warehouse, showroom, overseas agents or branches, and lists zero countries with overseas services; service assessment and corrective/preventive-action procedures also lack written records.

R&D capabilityThe supplier reports no new products during the past year, no ODM service, and no available SDK. Although customization is offered, these explicit limitations indicate insufficient evidence of active product innovation or software-development capability.

Production capacityThe supplier states that it operates five production lines, has an annual output range, and can achieve lead times within 15 working days in both seasons. However, it reports no in-stock capacity, while outsourcing procedures and manufacturing-capacity contracts have unknown status; overall production capability is therefore supported but not fully verifiable.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, full customization, and customization from designs or samples. This directly supports a broad customization capability, although no capacity limits or completed project evidence are provided.

Product Q&A

Q:What is a handheld auto refractometer?

A handheld auto refractometer is a portable, battery-operated ophthalmic device used to measure a patient's refractive error (sphere, cylinder, axis) and provide an objective eye prescription. It is designed for use in optometry clinics, optical shops, hospitals, and mobile screening programs. Unlike traditional tabletop models, our handheld version allows testing at the patient's bedside or in community outreach settings.

Q:How does an auto refractometer work?

The device projects an infrared light beam into the patient's eye and analyzes the light reflection from the retina. Advanced algorithms calculate the eye's refractive power and corneal curvature. The patient simply looks into the device - no eye drops, no contact, and no discomfort.

Q:Is the device easy to operate?

Yes. The device features a large 7-inch color touchscreen with an intuitive, user-friendly interface. Operators can complete a full measurement cycle in under 2 minutes with minimal training.

Q:Does it have a built-in printer?

Yes. Our handheld auto refractometer includes an integrated thermal printer that delivers instant, clear printouts of all measurement results. Printouts can be given directly to patients for prescription documentation or attached to medical records.

Q:Can it connect to a computer or EMR system?

Yes. The device supports Bluetooth and Wi-Fi connectivity, allowing seamless data transfer to computers, EMR systems, or mobile devices. This eliminates manual data entry and reduces errors.
