AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory in Longgang District, Shenzhen. It holds ISO 9001:2015 certification and reports documented procedures for R&D audits, supplier service capability, corrective and preventive actions, finished-product inspection, and complaint handling. R&D evidence includes two years of total engineer experience, 3D design services, SDK availability, ODM/OEM services, and new product development within the past year. Production operates across two lines, with 6–10 quality-control staff and stated annual output of 200,000 wireless controllers and 400,000 wireless remote controls. The supplier supports broad customization, exports to multiple global regions, and has 14 years of export experience. It lacks overseas warehouses, showrooms, agents, and branches. Customer evidence is limited to examples involving yacht turning and vehicle tailboard lifting, plus participation in exhibitions.

Supplier typeThe supplier is explicitly classified as a factory in the manufacturing industry, located in Longgang District, Shenzhen. This supports direct manufacturing status rather than a purely trading or service-provider profile.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. This is explicit evidence of a recognized quality-management-system certification, although no additional certifications are provided.

After-Sales capabilityR&D engineers are responsible for technical support during production and after-sales service, while the supplier reports documented complaint-handling procedures and records. This supports a defined after-sales process, though response performance or service coverage is not quantified.

R&D capabilityThe supplier reports new product development within the past year, available R&D audit documentation, 3D software design services, SDK availability, ODM services, OEM services for popular brands, and two years of total R&D engineer experience. These facts indicate active product-development capability, although the scale of the R&D organization is limited in the provided data.

Production capacityThe supplier operates two production lines, has 6–10 quality-control staff, and reports annual output of 200,000 wireless controllers and 400,000 wireless remote controls. It also uses standardized finished-product inspection instructions, quality assurance, and raw-material traceability, providing explicit evidence of organized production and quality control.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization, supported by 3D design services and ODM/OEM capabilities. This indicates broad customization coverage across both development and manufacturing services.

Client casesThe supplier cites customer applications involving RF technology for yacht turning and vehicle tailboard lifting, and reports attending seven exhibitions in different countries and regions over the past three years, including a Shenzhen Catering Expo. These provide some application and market-engagement evidence, but the slices do not identify customer names, project outcomes, or independently verifiable case details.

Product Q&A

Q:How long distance of your remote controls?

The distance has been marked on the product page. According to our testing standards, the distance of KRG series is among 30m-300m and KLR series is among 1,000m-31,000m.

Q:Is the antenna important? Can I remove the antenna?

Antenna is used to transmit/receive radio signal. It is very important for every RF product. The distance will be much shorter if the external antenna is removed, coz the power of radio can't be sent out. The circuit even may burn out especially for high power transmitters.

Q:Why all your products work at 433.92MHz/315MHz/868MHz? Can I have different frequency?

The frequency band is controlled by the governments. But the governments open some frequency bands for ISM(Industrial Scientific Medical) using which are license-free. We can make the product with special frequency for you if the frequency is license-free or you've got the license already.

Q:How long is the battery life?

Battery life depends on 3 factors which are power consumption, battery capacity, and pressing times. Normally, the battery of KRG series can last over 1 year if short pressing 5 times every day.

Q:What is coding type? What coding type do you have?

The code is the information included in the signal. We mainly have 2 coding types for ASK/OOK products which are Learning code(1527) and Rolling code(HCS301/300). We use our private coding type for FSK, LoRa and paging system.
