At the Topband Vietnam base, witness the power of advanced manufacturing.

In 2024, Topband Group (002139.sz, hereinafter referred to as "Topband") achieved a daily output value of 3.73 million yuan in its Vietnam base, with a daily production capacity of up to 100000 pieces at full capacity, ranking first in Topband overseas base production capacity and becoming an important growth pole in the company's global manufacturing system.

This outstanding achievement not only reflects the steady increase in production capacity of the Vietnamese base under mature operation, but also marks the deep landing of Topband "global manufacturing" strategy overseas, which will further promote the Vietnamese base to become a benchmark for Topband to build overseas "new quality productivity" manufacturing.

Vietnam is located on the Indochina Peninsula, adjacent to the South China Sea to the east and China, and is an important hub connecting the Asia Pacific and global markets. The continuously improving infrastructure, stable business environment, export convenience brought by multilateral free trade agreements such as RCEP and CPTPP, coupled with highly competitive young labor reserves and exchange rate advantages, make it an important recipient of China's orderly transfer of production capacity. In this favorable environment, Topband Vietnam Base undertakes the key mission of expanding the company's production capacity allocation and enhancing global delivery capabilities. The base continues the mature experience of Chinese manufacturing in technology, management, quality and other aspects, while combining with the cost advantage of Vietnamese manufacturing, significantly amplifying production capacity benefits, and will help create a "high-quality+high cost-effectiveness" intelligent manufacturing highland for global customers, enhancing the company's global comprehensive competitiveness.

The efficient output of the Vietnam base is not only attributed to the layout strategy of "relying on China and serving the world", but also to Topband consistent adherence to Chinese standards and continuous improvement of its manufacturing and operation system. Under the condition of relatively lacking local manufacturing capacity, strict intelligent, standardized, and lean full process management is implemented to efficiently coordinate all aspects from incoming materials, production, quality control to operation and maintenance, providing solid support for the release of overall factory capacity and operational efficiency.

China's same origin manufacturing capability empowers efficient production capacity

Digital intelligent manufacturing: In the past three years, Vietnamese factories have built a highly automated and digital modern manufacturing system from "0" to "1". At present, the factory is equipped with 20 automated production lines, and the MES system covers nearly 30 production lines. The digital kanban can update the material status in real time and automatically warn of abnormalities, achieving full process visibility, controllability, and traceability from raw materials to finished products. Based on intelligent production systems, the manufacturing quality of Vietnamese factories has achieved comprehensive compliance with Chinese standards.

Quality assurance: The Vietnamese factory continues to import advanced manufacturing and testing equipment that is the same origin as the Chinese headquarters, including 3D AOI systems, vacuum reflow soldering, selective wave soldering, ROS automatic optical screening systems, and three-dimensional measurement equipment (CMM), effectively ensuring the manufacturing quality of key processes such as mounting, welding, and testing. All quality inspection data can be uploaded, analyzed, and traced in real time, forming a quality loop and ensuring a stable yield rate of over 99.8% for the entire production line. At the same time, in order to strengthen quality assurance, the factory has set up two standardized laboratories and established a complete system covering factory testing and sampling, ensuring that every product is delivered to high standards. The full process quality management of the factory covers four major links: IQC, IPQC, FQC, and OQC, and has passed international management system certifications such as ISO 9001, ISO 14001, IATF 16949, truly achieving "consistent quality no matter where it is produced".

Process iteration: On the basis of inheriting Chinese manufacturing standards, the Vietnamese factory continuously promotes local optimization and process iteration. For example, by innovating furnace fixtures to increase UPH from 300 to 480 and introducing automatic dispensing equipment, product consistency has been greatly improved. This continuous optimization capability is a concrete manifestation of Tuobang's systematic manufacturing power, and it is also an important support for us to steadily output high-quality products worldwide.

Flexible manufacturing, creating differentiated delivery capabilities

Flexible manufacturing is another major advantage of the Vietnamese base. The factory adopts a small production line and diversified production line design, with the ability to conduct small-scale trial production and quickly introduce new products, supporting a closed-loop process from ordering to delivery within 30 days. The PMC system supports flexible scheduling and fast switching, accurately responding to customers' high-frequency and small batch customization needs, and building differentiated delivery capabilities for global customers. In addition, the Vietnamese base has a mature manufacturing transfer mechanism that supports the smooth introduction of trial production and mass production products, as well as the switching between multiple factories, including the orderly migration from Chinese factories to overseas bases such as Vietnam. Combining internal and external audits to ensure that processes are free from violations and standards do not deviate, achieving efficient replication and robust relay.

Lean operations support long-term and efficient growth
The base carries out multidimensional improvements around "lean+efficiency", establishes a lean production team to continuously explore improvement opportunities, and promotes process optimization and efficiency improvement; The cost reduction team focuses on optimizing the cost structure, strengthening equipment operation and maintenance management in conjunction with TPM (Total Productive Maintenance), and comprehensively enhancing the stability, predictability, and continuous improvement capabilities of the production site.

The Vietnamese base always puts customer satisfaction at the core, establishes a rapid response team, handles customer feedback and complaints in a timely manner, and strictly controls the processing time. Through a closed-loop management mechanism, regular risk analysis and inspection of the implementation of countermeasures are carried out to ensure the effective closure of improvement measures. With stable quality and agile response, the factory has been awarded the title of "Top 1 Supplier" by top customers for five consecutive years, winning high trust and recognition from global customers.

The Vietnam base plans to add approximately 75000 square meters of factory space, which is expected to be officially completed and put into operation before March next year. After production, the annual output value is expected to reach 4 billion yuan, further consolidating the company's manufacturing advantages and industry influence in Southeast Asia.

As the core node of Topband global manufacturing network, the goal of the Vietnam base is to build a regional benchmark factory that integrates cost advantages, efficient quality, and global delivery. In the future, the Vietnam base will continue to deepen its collaborative capabilities with the Chinese headquarters and global customers, further enhance automation ratios, deepen digital operations, optimize local supply chain support, and provide customers with manufacturing services that are more cost-effective, of higher quality, and more responsive. Topband will continue to take China as its root and Vietnam as its bridgehead, exporting high-quality manufacturing capabilities to the world and firmly becoming a trusted intelligent manufacturing partner for global customers.
