Ningbo JEC Shaft Manufacturing Co., Ltd. (formerly known as NINGBO JIECHENG AXLE TRADE CO., LTD.) is a leading supplier specializing in the precision machining of a wide range of shafts, including those used in the automotive industry. Founded in 1989 in Ningbo, Zhejiang Province, China, the company has undergone nearly 40 years of steady development. We currently employ over 200 staff members, including a dedicated technical team of more than 20 engineers.
With total fixed assets of RMB 240 million and a factory spanning over 20,000 square meters, we boast an annual production capacity exceeding 60 million precision-machined parts. Equipped with advanced domestic and international shaft machining equipment and precision testing instruments, our production technology ranks at the forefront of the domestic industry.
Our customer base spans both China and international markets, including the UK, USA, Mexico, Japan, and the Czech Republic. As a trusted throttle shaft supplier to the Portugal market, we are committed to delivering precision, reliability, and innovation.
Committed to development and innovation, we invest significant resources annually in new product R&D and technical upgrades. We have developed and successfully mass-produced a variety of shaft products, including welded shafts, gear shafts, servo motor shafts, wiper shafts, knurled shafts, and milling-edge shafts. Our portfolio also features new energy product lines such as electronic adjustment columns, ONE-BOX brake motor shafts, and E-bike powertrain motor shafts.
Portugal has emerged as a strategically important hub for precision mechanical components in Southern Europe. With a growing automotive sector anchored by the Setúbal and Palmela industrial zones — home to major OEM production facilities — and a rapidly expanding renewable energy and automation market, demand for high-quality throttle shafts and motor shafts has surged significantly in recent years. Portugal's membership in the EU also enables frictionless access to broader European supply chains, making it an ideal gateway for precision component procurement.
Portugal's Setúbal Peninsula hosts one of Europe's key automotive clusters. Throttle shafts are critical components in both combustion and hybrid vehicle throttle bodies, with local OEM and Tier-1 suppliers continuously seeking precision-machined parts that meet IATF 16949 standards.
Portugal has committed to carbon neutrality by 2050. The surge in EV adoption and wind/solar energy infrastructure has driven demand for high-precision motor shafts used in electric drivetrains, generators, and pump systems across the country's green energy projects.
Portuguese manufacturers are rapidly adopting Industry 4.0 technologies. CNC machining centers, robotic assembly lines, and servo-driven automation equipment all rely on precision servo motor shafts and splined shafts — areas where JEC excels with decades of expertise.
Portugal's agriculture and water infrastructure sectors use industrial pump motors extensively. Our high-performance pump motor shafts and welded shafts are engineered for the durability and corrosion resistance demanded by Portugal's irrigation and water treatment systems.
With Portugal's growing construction and smart building sector — especially in Lisbon and Porto — fan coil unit shafts for HVAC systems are in high demand. Our custom fan coil unit shafts deliver quiet, efficient performance for both commercial and residential applications.
Portugal's ongoing investment in rail modernization and urban transit systems creates sustained demand for precision motor shafts in traction motors and auxiliary systems. Our rail-grade shaft solutions meet the stringent reliability requirements of public transportation networks.
The Portuguese government's aggressive EV adoption targets are reshaping the automotive supply chain. Throttle shaft manufacturers must evolve to supply precision components for electric motor systems, including E-bike powertrain shafts and ONE-BOX brake motor hollow shafts that meet the demands of next-generation vehicles.
Friction welding technology produces shafts with superior joint strength and minimal material waste — ideal for Portugal's sustainability-focused industrial policy. JEC's friction welded shafts are increasingly specified by Portuguese engineers for pump, motor, and heavy-duty machinery applications.
Post-pandemic supply chain disruptions have prompted Portuguese manufacturers to diversify their supplier base. Partnering with a certified, high-capacity manufacturer like JEC — with proven export logistics to Europe — provides Portuguese buyers with supply security, competitive pricing, and consistent quality.
Portugal's Industry 4.0 roadmap encourages factories to adopt smart sensors, CNC automation, and data-driven quality control. JEC's manufacturing digitalization capabilities — recognized at Ningbo Level II — align perfectly with Portuguese buyers seeking partners who can integrate into digital supply chain ecosystems.
EU environmental regulations demand that component suppliers maintain ISO 14001 environmental management certification. JEC's certified green factory status and commitment to eco-friendly production processes make it an ideal long-term partner for Portuguese companies navigating strict EU compliance requirements.
Portuguese OEMs and Tier-1 suppliers increasingly require custom-engineered shaft solutions with rapid prototyping and flexible batch sizes. JEC's dedicated R&D team of 20+ engineers and its 60-million-parts annual capacity enable fast turnaround on bespoke throttle shaft designs tailored to specific Portuguese market requirements.
Decades of exporting to the UK, USA, Japan, Czech Republic and beyond. We understand EU compliance, documentation, and logistics requirements for the Portugal market.
Our 20+ engineer R&D team delivers bespoke throttle shaft designs. From prototype to mass production, we tailor every specification to your exact requirements.
Our automotive-grade quality management system ensures every shaft meets the precision tolerances demanded by Portuguese OEMs and Tier-1 automotive suppliers.
ISO 14001 certified and recognized as a Green Factory. Our eco-conscious manufacturing aligns with Portugal's EU environmental compliance obligations.
