Our facility is located in the newly upgraded Yinggong Fengqi Industrial Park in Yinzhou, Ningbo — a benchmark redevelopment zone planned and operated by state-owned Yinggong Group. The park features modern high-rise industrial buildings, integrated production and office spaces, and an ecosystem focused on intelligent manufacturing, digital technology, medical devices, and high-end equipment.
ABOUT OUR FACTORY AND SCALE
Ningbo Anjie Electronic Technology Co. Ltd. (AJE Electronic Technology) is a full-service electronics engineering and manufacturing company based in Ningbo, China, specializing in OEM/ODM product development for global brands and innovators.
We provide end-to-end solutions to bring your product ideas to life — from concept development, industrial design, and electronic engineering to rapid prototyping, certification support (CE, FCC, RoHS), and scalable mass production.
Our core capabilities include PCBA design and manufacturing (SMT & THT), embedded firmware development, injection mold design and plastic molding, structural and mechanical engineering, and complete box-build assembly. By integrating hardware, software, and manufacturing under one roof, we significantly reduce development time, cost, and supply chain complexity.
With ISO-certified production management systems, advanced testing and quality control processes, and strong supply chain integration, we ensure consistent product reliability and compliance for international markets across Europe, North America, and beyond.
Whether you are a startup developing a new electronic device or an established brand scaling production, AJE serves as your trusted electronics contract manufacturing partner in China, delivering high-quality, production-ready solutions with speed and precision.
HOW WE WORK
From Idea to Production
A clear development pathway from concept definition and engineering to prototyping, tooling, pilot production and scalable manufacturing.
Selected feedback from clients who worked with our engineering and manufacturing teams from concept to production.
Client feedback received during functional testing and engineering verification of the latest prototype revision.
Client feedback during internal review of revised quotation, tooling costs and estimated production pricing.
Initial client feedback after receiving and reviewing the first working prototype.
Client feedback after reviewing an updated prototype and assessing improvements in assembly, finish and overall product direction.
Client feedback after reviewing updated CAD files and the latest structural design revisions.
Learn how AJE supports brands, startups and product companies with electronics engineering, prototyping, PCBA, injection molding, assembly and scalable mass production in China.
AJE Electronic Technology, formally Ningbo Anjie Electronic Technology Co. Ltd., is an electronics engineering and manufacturing company based in Ningbo, China. We help brands, startups and product companies develop custom electronic products from early concepts to production-ready designs and scalable mass production.
Our capabilities include product definition, industrial design, mechanical engineering, schematic and PCB design, embedded firmware development, PCBA manufacturing, prototyping, testing, injection molding, complete product assembly, packaging and global delivery.
Yes. AJE provides end-to-end electronic product development and manufacturing services, supporting projects from product definition and engineering feasibility through industrial design, electronics, firmware, mechanical engineering, prototyping, tooling, injection molding, PCBA manufacturing, final assembly, testing and mass production.
Because engineering and manufacturing are integrated within one team, product decisions can be evaluated for manufacturability, cost, reliability and scalability early in the development process, reducing unnecessary handoffs and redesign risks later.
Yes. You do not need to have finished engineering files before contacting AJE. We can begin with an early concept, reference product, functional requirements, sketches or preliminary specifications.
During the product definition and engineering feasibility stage, our team can help clarify use cases, technical requirements, product architecture, component strategy, structural requirements, target cost and manufacturing constraints before significant investment is made in tooling or production.
AJE develops and manufactures custom electronic and electromechanical products across applications including pet and animal care, automotive electronics, smart home and IoT devices, medical and wellness products, industrial equipment, environmental monitoring, security and access control, consumer electronics and small home appliances.
Our experience covers technologies such as Bluetooth, Wi-Fi, NB-IoT, RFID, biometric modules, sensors, displays, power electronics, embedded control systems and connected IoT products.
Yes. AJE provides integrated electronics development covering schematic design, multi-layer PCB layout, component selection, MCU and wireless module integration, embedded firmware development, hardware-software debugging, programming, functional testing and PCBA manufacturing.
Our manufacturing capabilities support prototype builds, EVT, DVT and PVT stages, as well as stable volume production using SMT, DIP and mixed-technology assembly processes.
Yes. AJE can integrate industrial design, mechanical and structural engineering, electronics, firmware, mold development, injection molding, PCBA manufacturing and final product assembly within a single development program.
Mechanical designs are developed with production requirements in mind, including material behavior, tolerance stack-up, assembly efficiency, heat dissipation, mechanical strength, tooling complexity and mold life. This helps products transition more smoothly from prototype validation into scalable manufacturing.
Development time depends on product complexity, technical requirements and the starting point of the project. As a general reference, AJE typically estimates approximately 6–10 weeks from concept to prototype for projects involving industrial design, mechanical development, electronics engineering and functional prototype validation.
Simple projects may move faster, while products involving complex wireless systems, custom firmware, multiple prototype iterations or extensive testing may require additional time.
Yes. AJE supports electronic products throughout the development and manufacturing lifecycle, including engineering prototypes, EVT/DVT/PVT builds, small-batch validation, production ramp-up and stable mass production.
Our PCBA manufacturing, injection molding, assembly and testing operations are structured to support the transition from early validation to repeatable production, with quality checks and functional testing integrated throughout the manufacturing process.
Yes. AJE supports functional testing, electrical verification, environmental and reliability testing, aging and burn-in testing, and EMC pre-compliance evaluation based on project requirements.
For products intended for international markets, AJE can also support preparation for certifications and regulatory requirements such as CE, FCC and RoHS. Final certification requirements depend on the product type, target country, wireless technologies and applicable regulations.
AJE combines product engineering and manufacturing within one integrated team. This allows electronics, firmware, mechanical design, tooling, PCBA, injection molding, assembly and testing decisions to be coordinated from the beginning rather than handled by separate suppliers at different stages.
For clients, this can mean fewer handoffs, clearer technical responsibility, faster engineering decisions and earlier identification of risks related to manufacturability, tooling, cost, testing and production scalability.
