The rapid advancement of the new energy vehicle industry drives the component manufacturing sector to upgrade towards higher precision, lighter weight and larger production scale. To keep pace with industrial trends, Nanjing Langjin Intelligent Manufacturing Co., Ltd. focuses on core products including steering parts and lightweight structural components for new energy vehicles. The company has increased investment in R&D and high-end equipment, and built a digital production system that enables full-process data collection and intelligent scheduling for die-casting. Its equipment automation rate exceeds 90%, effectively resolving longstanding issues such as unstable precision and low efficiency in traditional manufacturing. This has greatly improved product yield and delivery capacity, consolidating its core position in the new energy supply chain.

The company has increased investment in R&D and high-end equipment, and built a digital production system that enables full-process data collection and intelligent scheduling for die-casting. Its equipment automation rate exceeds 90%, effectively resolving longstanding issues such as unstable precision and low efficiency in traditional manufacturing. This has greatly improved product yield and delivery capacity, consolidating its core position in the new energy supply chain.
Langjin’s major breakthrough in integrated die-casting and full-process smart production is largely attributed to nine sets of CATO A8 5-axis horizontal cradle machining centers deployed in four batches. Serving as the core equipment for its steering column production lines, these machines lay a solid hardware foundation for intelligent manufacturing upgrading. The CATO A8 5-axis horizontal cradle model is perfectly suited for machining precision and complex workpieces such as aluminum alloy steering housings and chassis structural parts for new energy vehicles. Featuring high rigidity, high precision and excellent dynamic response, it connects the entire intelligent production chain from die-casting to precision machining. The equipment has completely eliminated the production capacity and technical bottlenecks of the company’s traditional production, helping Langjin join the ranks of high-end intelligent manufacturers in the new energy sector.
Xu Xin, Technical Director of Langjin, commented: "CATO 5-axis machines are the optimal solution for new energy steering parts, and they fit local mass production rhythms better than German-made equipment." According to Director Xu, conventional general-purpose machine tools show obvious drawbacks in mass production. Their mechanical transmission structures are prone to backlash and wear, with the 3-axis repeat positioning accuracy only reaching ±0.02 mm, which fails to meet the micron-level tolerance requirements of new energy components. In addition, slow cutting speed and complicated working procedures lead to long production cycles and restricted output. Such equipment also suffers from insufficient rigidity and frequent malfunctions, with an overall equipment utilization rate below 80%, making it unfit for high-volume, high-precision continuous production of new energy parts.
Since adopting the CATO A8 model, the company has achieved an all-round improvement in production capacity. Equipped with a backlash-free direct drive structure, the machine delivers a 3-axis repeat positioning accuracy of ±0.006 mm, and the angular positioning accuracy of A/B axes remains stable at 6 arcseconds. No precision degradation occurs even after long-term mass production, ensuring consistent machining quality.In terms of efficiency, the rapid traverse speed of the three axes reaches 90 m/min with a maximum acceleration of 1G. It allows multi-surface machining in a single clamping setup, cutting the processing time per workpiece from the original 20 minutes to less than 5 minutes and bringing a substantial increase in output.Built with a high-rigidity machine bed and direct drive motors, the equipment boasts outstanding vibration resistance and fewer wearing parts. It supports 24-hour unattended operation and lifts the equipment utilization rate to over 95%, fully complying with the requirements for fast delivery and large-scale mass production in the local new energy industry.
When it comes to after-sales service, CATO stands out with strong localized support. It addresses the common pain points of imported German equipment, including slow service response, high maintenance costs, long lead time for spare parts and production downtime losses. With 24-hour rapid response, dedicated technical support and timely spare parts supply, CATO helps customers cut maintenance costs, avoid production halts and safeguard large-scale intelligent mass production.
The new energy vehicle industry continues to evolve toward integration, lightweight design and intellectualization. High-end machine tools, known as the mother of industry, serve as the core support for manufacturers to break technical barriers and achieve upgrading. The in-depth cooperation between Langjin and CATO A8 precision machining centers, backed by the large-scale deployment of premium 5-axis equipment, has not only helped the customer realize intelligent manufacturing transformation, improve quality and efficiency, and build a benchmark for new energy component production, but also fully proven the reliable performance of domestic high-end machine tools adapted to local mass production scenarios.
