Company & Manufacturing
Is E-Lins a manufacturer or a trading company?

E-Lins Technology is a manufacturer, not a trading company. Our hardware is designed in-house, manufactured at our own facility in Shenzhen, and backed by our own engineering team. We have been designing and manufacturing industrial cellular devices since 1999. We do not resell third-party products under our brand.
Where are E-Lins products designed and manufactured?

All E-Lins products are designed and manufactured in Shenzhen, China. Our R&D, hardware engineering, firmware development, production, and quality assurance teams are all located at our Shenzhen facility. We do not outsource manufacturing to third parties.
How long has E-Lins been in business?
+
E-Lins Technology was founded in 1999 — making us one of the longest-established industrial cellular connectivity manufacturers in China. We have been designing M2M and IoT connectivity hardware for 27 Years, predating the widespread use of the term "Industrial IoT."
What quality certifications does E-Lins hold?

OEM / ODM
What is the minimum order quantity for OEM/ODM?
+
The minimum order quantity for OEM/ODM customization is
50 units. This applies to firmware customization, custom branding, and hardware modifications. For standard off-the-shelf products, there is no minimum order quantity — you can order as few as 1 unit via our
online store.
What can be customized under the OEM/ODM program?
+
Our OEM/ODM program covers: custom firmware (white-label web UI, custom APN presets, feature lockdown, OTA update server), custom branding (logo, color scheme, boot screen, product label, packaging), hardware modifications (enclosure design, antenna configuration, connector customization), and certification support for custom SKUs. We also sign full NDA agreements from the first inquiry.
What is the typical lead time for OEM orders?
+
Typical lead time for OEM orders is 6–8 weeks from order confirmation and deposit receipt. This includes firmware customization, branding, production, QA testing, and shipment preparation. Lead times for hardware design modifications may be longer — contact our OEM team for a precise timeline based on your requirements.
