WJ-LEAN Technology Co., Ltd. is a manufacturer focusing on lean production automation and its technical solutions. The company is headquartered in Dongguan, Guangdong Province, with a global market layout and comprehensive service agencies in many countries around the world.
The products are widely used in mechanical frame structure and connection of various parts, industrial assembly lines and conveyor belts, small motor equipment and non-standard electromechanical equipment, industrial inspection and testing and safety protection equipment. Including electronics, auto parts assembly lines, home appliances, chemicals, furniture advertising, medical food, cleaning equipment and other fields. By 2020, WJ-LEAN has provided more than a thousand products to the world.
Every component is manufactured to exact tolerances, ensuring seamless integration with Singapore's high-standard industrial environments.
Comprehensive service agencies across multiple countries ensure fast delivery and after-sales support for Singapore clients.
Fully configurable flow rack and lean pipe systems tailored to the specific workflows and space requirements of Singapore factories and warehouses.
From MB aluminum profiles to linear modules, workbench systems and elevator platforms — a full ecosystem for lean automation.
Singapore is one of Southeast Asia's most advanced manufacturing and logistics hubs, where efficiency, precision, and lean principles are not just goals — they are operational imperatives.
Singapore's manufacturing sector contributes approximately 20–21% of GDP, encompassing electronics, precision engineering, biomedical manufacturing, aerospace, and specialty chemicals. With over SGD 100 billion in annual output, the sector demands highly efficient intralogistics infrastructure. Flow rack systems play a pivotal role in assembly line management, component staging, and FIFO inventory control across Jurong Island industrial estates, Woodlands industrial parks, and Tuas mega-port industrial zones.
As the world's second-busiest container port and a global air freight hub, Singapore handles enormous volumes of goods daily. Third-party logistics (3PL) providers, distribution centres, and fulfillment hubs in areas such as Pandan Loop, Kallang and Airport Logistics Park of Singapore (ALPS) rely on dynamic storage solutions. Gravity-fed flow racks and lean pipe racking systems optimise pick-and-pack operations, reduce travel time for warehouse staff, and support Singapore's stringent health, safety, and efficiency standards.
Under Singapore's Smart Industry Readiness Index (SIRI) and the Advanced Manufacturing Training Programme, local enterprises are rapidly adopting Industry 4.0 technologies. Flow rack systems with modular lean pipe components integrate seamlessly with automated guided vehicles (AGVs), robotic picking arms, and digital warehouse management systems. The adaptable, tool-free assembly of WJ-LEAN systems makes them ideal for Singapore's agile manufacturing environment, where rapid reconfiguration to accommodate new product lines is a competitive necessity.
Several powerful macro-trends are accelerating the adoption of flow rack and lean pipe racking systems across Singapore's industrial base.
Singapore's pharmaceutical, food manufacturing, and electronics sectors operate under strict first-in, first-out (FIFO) regulatory requirements. Gravity-fed flow racks inherently enforce FIFO rotation, minimising spoilage, expiry risks, and component errors. As Singapore aligns with GMP and ISO standards, lean pipe flow rack adoption has surged across cleanroom environments, semiconductor fab support areas, and food production lines in Senoko and Tuas Food Zones.
Post-pandemic supply chain restructuring has driven many multinationals to establish or expand Singapore operations as a regional supply chain hub. Companies are investing in flexible warehouse infrastructure that can quickly adapt to changing product mixes. Modular lean pipe racking from WJ-LEAN enables rapid reconfiguration without tools or specialist labour, making it the preferred choice for Singapore's dynamic supply chain operations at logistics parks in Changi South and Ubi.
Singapore's Green Plan 2030 and Enterprise Sustainability Programme encourage businesses to reduce material waste and energy consumption. Flow rack systems made from recyclable aluminum and lean pipe materials align with Singapore's circular economy goals. The durability and reusability of WJ-LEAN components mean significantly lower total cost of ownership and reduced environmental footprint — a key purchasing consideration for ESG-conscious Singapore enterprises and MNCs.
Singapore's e-commerce sector has grown dramatically, with major platforms expanding fulfilment centre capacity across Jurong, Tampines, and Toa Payoh logistics hubs. High SKU variety and rapid order fulfilment demand optimised picking systems. Flow racks provide ergonomic, gravity-assisted picking that reduces picker fatigue and fulfilment errors. Karakuri-inspired systems with aluminium roller tracks are increasingly being deployed in Singapore's high-velocity omnichannel warehouses to meet next-day and same-day delivery commitments.

The journey of WJ-LEAN from a single idea to a global lean production leader.
In 2005, Wu Jun, who had long heard that Japan had advanced production technology, came to a Japanese company in Dongguan to study manufacturing. When he came to this company again in 2008, he found that a production line of the Japanese company at that time only took 2 days from assembly to use.
Since then, I have a bold idea to introduce this advanced production line into China and carry it forward, and continuously improve the material technology. Later, in order to attract business, he simply sold all the spare parts of this lean production to the world. Five years later, his "Wu Jun" brand spare parts have been sold all over the world. In order to make local customers more satisfied, he personally released the market and communicated with many customers around the world in depth.
But due to external accent problems, locals always call "Wu Jun" a pronunciation similar to "weijie", and the Weijie brand was born. In 2020, the company's brand will be upgraded and its name will be officially changed to "WJ-lean".
We use highly adjustable mechanisms and actuators as well as other necessary solutions to deliver fully functional products. The company has all industry product systems, including but not limited to MB industrial aluminum profile assembly system, lean production system, linear module system, workbench system and small elevator platform system. Provide advanced solutions for lean production automation, ergonomics and future intelligent manufacturing.
