On December 5th, the "2025 Geely Automotive Metal Forming Industry Chain Innovation Development Forum," hosted by the Geely Automotive Stamping Association, was successfully held at Geely Automobile's Yuyao Plant in Zhejiang. Centered around the theme "Geely Chain Collaboration, Intelligent Manufacturing for the Future," the forum brought together technical, procurement, and manufacturing leaders from various Geely plants along with core suppliers to explore cutting-edge technologies and collaborative innovation in the field of metal forming.

As an invited premium supplier, Penta Laser’s spokesperson, Mr. Li Yinhua, delivered a keynote technical presentation titled "Applications of Penta Laser's 3D Cutting Machines in the High-Strength Steel Body Lightweight Industry." The presentation highlighted Penta Laser's leading technology and application achievements in 3D laser cutting for high-strength steel and aluminum alloy automotive body components.

Specialized Insights: Addressing Pain Points in Lightweight Manufacturing

In the presentation, Penta Laser pointed out that with the rapid development of the new energy vehicle industry and the deepening trend toward vehicle lightweighting, the use of high-strength steel (1500-2000 MPa) hot-formed components in critical automotive safety structures is becoming increasingly widespread. However, traditional stamping and trimming molds face significant challenges when processing these high-strength materials, including high mold costs, long lead times, slow iteration, and insufficient flexibility. These limitations make it difficult to adapt to the market demand for rapid model updates and multi-variant production.

Driven by the pursuit of higher efficiency and greater flexibility, 3D five-axis laser cutting technology has emerged as a key enabler, offering broad application potential to address these industry challenges.

Against this backdrop, the need for more flexible and efficient processing methods has become a pressing industry requirement. This has created favorable conditions for the widespread adoption of 3D five-axis laser cutting technology and laid the groundwork for subsequent technical solutions.

Technology Application: Laser Empowering the 'Steel Skeleton'

Penta Laser further elaborated in the report that with the widespread application of ultra-high-strength steel hot-formed components (with strengths up to 2000 MPa), traditional stamping processes face immense challenges. Penta Laser’s 3D five-axis laser cutting technology, with its advantages of "no molds required, non-contact processing, high precision, and high flexibility," is becoming a critical process solution to address these industry pain points.

01 Processing Hot-Formed Components: An Industry-Standard Process

With minimal heat-affected zones and no workpiece deformation, 3D laser cutting serves as an excellent replacement for traditional trimming and punching molds. It significantly enhances the efficiency of new vehicle prototype development and has become the preferred process for leading automotive manufacturers in processing hot-formed components.

02  Integrated Door Ring Cutting: Enabling Structural Weight Reduction by 20%

For integrated door rings with strengths as high as 1500 MPa, Penta Laser offers specialized 3D cutting solutions that achieve higher cutting precision and edge quality while meeting the demands of complex contour processing. This approach has garnered significant attention from mainstream automakers.

03 Battery Trays and New Material Components

In application scenarios involving new materials such as new energy vehicle chassis, battery trays, and aluminum alloy frames, 3D laser cutting also demonstrates its advantages in high flexibility and consistency.

04 Cross-Industry Adaptability

Beyond automotive manufacturing, Penta Laser’s 3D five-axis technology has also matured in fields such as mold manufacturing, engineering machinery, and the processing of various other complex three-dimensional curved components, showcasing strong potential for cross-industry expansion.
