Metal Detail Welding Line For Automotive Production

Our client is a domestic leader in applying automation to production.

Challenges and Requirements

Understanding their societal mission and commitment to green energy for environmental protection, our client made a bold decision: transitioning from gasoline vehicle production to electric vehicles. This was not only a challenging move but also required a comprehensive transformation in production processes, with the pressure to complete in a short time frame for the new product launch. The challenge was even more significant as the client is one of the pioneers in developing domestic electric vehicles. The lack of specialized documentation and production experience made the task more complex. In this journey, ETEK was a partner and a companion, ready to face difficulties with the client to realize shared goals and introduce innovative solutions at every development stage.

Pioneering Technology – Partnering with Clients

With over 20 years of experience in construction and development, we applied our extensive expertise, collaborating with leading global partners in the welding field. We delivered a solution that fully met the established requirements alongside our commitment to accompany our client closely. Additionally, we proactively proposed alternative solutions to cope with disruptions in the global supply chain, all aimed at our core goal: COST OPTIMIZATION – QUALITY ASSURANCE – TIMELY PROGRESS.

Core Technology Enabling Our Success in This Project:

  • Spot Welding Technology: We use specialized welding robots from ABB – a longstanding and reputable global brand. Our programming engineers worked closely with experts from ABB to set optimal welding parameters, ensuring each welding point achieved high precision and stability. The system also integrates cooling air technology, enhancing equipment performance and longevity.
  • Adhesive Application Technology: Robots equipped with modern adhesive application tools and cameras check positioning and adhesive lines to ensure absolute accuracy during operations. We also meticulously calculated the adhesive’s drying time to provide synchronization and efficiency across the entire production line.
  • End-of-Line (EOL) Testing Technology: The end-of-line inspection process includes visual inspection, leak testing, and product dimension measurement. This technology ensures that all products meet high-quality standards before leaving the factory.

Thanks to the synchronized application of these technologies, we delivered a comprehensive production solution, contributing to the project’s success.

Challenges During Implementation

The project was implemented amid the country’s complex and widespread COVID-19 pandemic. Pandemic prevention measures were prioritized, creating significant challenges for routine production activities. To ensure project timelines, we rapidly introduced a series of flexible solutions to adapt and maintain work efficiency. Besides the challenges posed by the pandemic, the supply of raw materials was also a significant factor affecting the project. Controlling the sanitation of raw materials played a crucial role, directly impacting the quality of the welds and the durability of the products after adhesive application. Strict standards in this control phase helped us maintain product quality despite numerous obstacles.

Achieved Success

We successfully developed an optimized metal welding and adhesive application solution, launching the production line in time to meet production demands. The line operates continuously and stably, effectively addressing the shortage of skilled welders during the COVID-19 pandemic. Mastering spot welding technology on metal products allowed us to comprehensively control the quality of welds and adhesive lines, ensuring sustainability, aesthetics, and high standards. This success not only demonstrated our team spirit and determination to overcome difficulties but also affirmed our capabilities in the eyes of our clients. This lays a solid foundation for future projects, opening up many sustainable cooperation and development opportunities.

Plans for the Future

After a period of operation, the automated line has demonstrated the superior benefits of this technology. The effectiveness in production not only reinforced the client’s confidence in the value of automation but also spurred them to plan quickly to expand this technology to other production stages. Additionally, the client is implementing plans to replicate similar lines for various product lines, maximizing the benefits of automation to enhance productivity, quality, and market competitiveness in an increasingly stringent market.
