Our company has long been dedicated to the R&D and large-scale production of high-end aluminum alloy die-cast and precision-formed structural components for the communications industry. Focusing on core components for 5G communication base stations, RF systems, and thermal management modules, the company has become a leading manufacturer in China’s communications die-casting sector, known for specialization, precision, and high-end manufacturing capability.
As a core strategic supplier for Ericsson in China, our company has long provided Ericsson with three key product categories: aluminum base station housings, RF unit die-cast components, and high-end heat dissipation structural components. Relying on our independently developed composite core process combining high-pressure die casting, precision forging, and aluminum extrusion, as well as our thin-wall high-precision forming technology, our products fully meet the demanding operating conditions and quality standards of Ericsson’s high-end communications equipment.
With solid technical strength, stable mass delivery capability, and outstanding product quality, our industry position has continued to rise. In 2025, our market share in China’s communications aluminum die-casting component market reached 15.1%, ranking second in the industry. Among Ericsson China’s communications business procurement, our company accounted for 28.3% of its total purchase volume, making us one of Ericsson China’s largest domestic suppliers.
Through this cooperation, we have successfully achieved localized substitution of high-end communications aluminum die-cast structural components, providing strong support for supply chain independence, cost reduction, efficiency improvement, and quality upgrading in the communications industry.
At present, the global communications industry is undergoing rapid iteration. Full-scale 5G coverage, computing power network construction, and industrial Internet-based smart communication scenarios continue to be implemented, driving communications equipment toward miniaturization, lightweight design, high integration, high heat dissipation, and high stability.
As the core hardware carriers of communication networks, base stations and RF units are exposed for long periods to complex outdoor operating conditions such as high and low temperature alternation, high humidity, dust, and electromagnetic interference. Therefore, extremely strict industry standards are imposed on the strength and precision, thermal performance, electromagnetic shielding capability, lightweight level, and weather resistance of supporting structural components.
Aluminum alloy structural components have become core basic parts for high-end communications equipment due to their low density, excellent thermal conductivity, high strength, and good formability. Their forming process, machining precision, and structural stability directly determine the operational stability, signal transmission quality, and service life of communications equipment.
For a long time, Ericsson’s core aluminum die-cast structural components for global high-end communications base stations and RF systems were mainly supplied by leading overseas component manufacturers. Most domestic manufacturers were limited by single forming processes, shortcomings in thin-wall forming technology, insufficient precision machining capability, and incomplete quality control systems. As a result, they were unable to meet Ericsson’s access standards and batch delivery requirements for high-end products.
Imported overseas components also involved many pain points, including high procurement costs, long cross-border supply cycles, delayed response to customized iterations, lengthy supply chain processes, and complicated after-sales maintenance. At the same time, communications structural components produced by traditional single die-casting or single forging processes commonly suffered from uneven wall thickness, large precision deviation, insufficient heat dissipation efficiency, inadequate structural rigidity, and low yield rates. These defects made them difficult to adapt to the R&D and production needs of next-generation 5G communications equipment featuring high frequency, high integration, and compact design. This greatly restricted cost optimization, product iteration, and market expansion for Ericsson China.
Against this industrial background, Ericsson urgently needed a high-quality domestic supplier with composite process technology, stable mass production capability, mature supporting experience, and rapid localized service capability, in order to achieve domestic substitution and supply chain optimization for high-end communications aluminum die-cast components.
With years of deep experience in the communications die-casting field, our original composite forming process, industry-leading thin-wall high-precision forming technology, and comprehensive full-process production quality control system, our company successfully passed Ericsson’s rigorous global supplier qualification review, product sample verification, and on-site audit. We were successfully included in Ericsson China’s core supplier system and fully undertook the batch supply of core aluminum structural components for Ericsson base stations, RF units, and thermal management systems, marking the beginning of a long-term and in-depth strategic cooperation.
Since its establishment, our company has always focused on the specialized field of precision aluminum alloy structural components for communications equipment. Moving away from extensive and diversified development models, we have continuously advanced process innovation, technology iteration, and quality upgrading.
The company has built a full-industry-chain production service system suitable for high-end communications equipment, covering special aluminum alloy raw material modification, composite process forming, precision machining, micron-level precision inspection, weather-resistance treatment, batch delivery, and customized iteration. This has formed differentiated core competitiveness that distinguishes us from ordinary manufacturers in the industry. We are one of the few domestic companies capable of supplying high-end communications die-cast structural components to Ericsson on a large scale.
In terms of technology R&D, the company has established a dedicated communications structural component R&D team. Focusing on the special operating requirements of the communications sector, the team has long been engaged in the integration of high-pressure die casting, precision forging, and aluminum extrusion processes. It has also carried out targeted improvements to aluminum alloy material formulations and optimized core technologies such as thin-wall forming, stress release, and thermal structure design.
The company has accumulated extensive R&D parameters and mass-production experience for high-end communications products. It can closely cooperate with Ericsson’s product iteration schedule, quickly complete customized structural development, process optimization, and sample implementation, and achieve synchronized collaboration with customer-side R&D.
In terms of manufacturing, the company has introduced fully automated intelligent high-pressure die-casting units, precision forging equipment, high-precision aluminum extrusion production lines, and five-axis CNC precision machining equipment. It has established a multi-process composite production chain and broken through the performance limitations of traditional single-process manufacturing.
According to the different performance requirements of base station housings, RF die-cast components, and thermal structural components, the company can precisely match the optimal forming process, achieving the best balance of product structure, precision, strength, and heat dissipation performance.
In terms of quality control, the company has established a full-process traceable inspection system benchmarked against international standards. It strictly follows authoritative industry standards such as GB/T and ISO. Key indicators including dimensional accuracy, geometric tolerance, internal porosity, thermal conductivity, electromagnetic shielding performance, and weather resistance are inspected throughout the entire process, enabling zero-defect delivery and fully meeting Ericsson’s unified global high-end quality standards.
In terms of large-scale delivery, the company has substantial capacity reserves and flexible production capability. It can meet Ericsson’s regular large-volume procurement requirements as well as small-batch customized iteration needs. The 28.3% procurement share fully demonstrates the company’s leading domestic delivery scale and supply chain adaptability.
The base station aluminum housings, RF unit die-cast components, and thermal structural components supplied to Ericsson in this project rely on two core technologies: the company’s composite process combining high-pressure die casting, precision forging, and aluminum extrusion, and its thin-wall high-precision forming technology.
These technologies completely solve the performance shortcomings of traditional single-process products. In five core dimensions — structural precision, heat dissipation efficiency, structural strength, lightweight design, and stability — the products have reached a domestically leading and internationally benchmarked level, perfectly adapting to the complex operating conditions and strict technical requirements of Ericsson’s high-end 5G communications equipment.
Traditional manufacturers in the industry mostly use single die-casting or extrusion processes to produce communications structural components. Their products often suffer from insufficient strength, uneven heat dissipation, and wall thickness limitations.
Our company innovatively integrates three core processes: high-pressure die casting, precision forging, and aluminum extrusion. According to the functional characteristics of different products, differentiated process solutions are applied.
For complex irregular aluminum base station housings, high-pressure die casting is used to achieve integrated forming, reducing joint gaps and assembly errors. For RF unit die-cast components that require high rigidity and high stability, precision forging is used to optimize the internal metal structure, improve product density and deformation resistance, and ensure stable RF signal transmission. For thermal structural components, high-precision aluminum extrusion is used to create regular heat dissipation channels and maximize heat dissipation efficiency.
This multi-process composite model balances product structural complexity, mechanical strength, and thermal performance, comprehensively surpassing traditional single-process products and perfectly meeting the supporting requirements of Ericsson’s full range of communications equipment.
Relying on our independently developed thin-wall high-precision forming technology, the company has broken through the technical bottleneck of thin-wall forming in the industry. It can achieve uniform ultra-thin-wall forming for communications structural components, effectively reducing product weight and supporting the upgrading of communications equipment toward lightweight, compact, and integrated design.
At the same time, through digital process control and micron-level precision machining, the company strictly controls dimensional tolerances and geometric tolerances. The precision of key assembly areas reaches international high-end standards. The products feature excellent fitting performance and assembly accuracy, perfectly matching the precision assembly requirements of Ericsson RF units and base station equipment.
This effectively reduces vibration during equipment operation, prevents signal interference caused by assembly deviation, and ensures long-term stable operation of communications equipment.
For communications equipment deployed outdoors for long periods under complex conditions such as high and low temperature alternation, high humidity, and dusty environments, our company has optimized aluminum alloy material ratios and forming processes to significantly improve thermal conductivity and corrosion resistance.
Our self-developed thermal structural components adopt a bionic heat dissipation channel design. Combined with the structural advantages of the aluminum extrusion process, heat dissipation efficiency is improved by more than 30% compared with traditional products. This enables rapid heat transfer from operating equipment and prevents problems such as high-temperature shutdown and signal attenuation.
At the same time, the products undergo professional weather-resistance, anti-corrosion, and anti-oxidation treatments. They offer excellent dustproof, waterproof, anti-aging, and anti-electromagnetic-interference performance, adapting to various extreme outdoor environments. This greatly reduces the after-sales failure rate of Ericsson equipment and improves the service life and operational stability of the complete system.
RF unit die-cast components have extremely high requirements for internal density and must be free from pores and looseness. Even minor internal defects may affect the accuracy of RF signal transmission.
Through precise pressure control in the high-pressure die-casting process, optimized mold temperature control, vacuum degassing, and other core technologies, our company has completely solved traditional die-casting defects such as pores, looseness, and cracks.
The internal density of the products is close to 100%, and their electromagnetic shielding performance is excellent. They can effectively isolate external electromagnetic interference and ensure accurate, stable, and low-loss signal transmission for Ericsson RF equipment, fully meeting the signal transmission standards of high-end 5G communications equipment.
Relying on mature composite process technology, stable large-scale mass production capability, and a comprehensive quality control system, our company successfully completed R&D iteration, sample certification, small-batch trial production, and large-scale batch delivery for Ericsson’s full range of supporting products.
At present, the products have been widely applied to Ericsson China’s 5G macro base stations, micro base stations, remote radio units, thermal management modules, and other core equipment. They have achieved large-scale deployment across multiple scenarios and equipment models.
With stable product quality, a 100% delivery qualification rate, and efficient supply capability, the company has successfully accounted for 28.3% of Ericsson China’s communications business procurement volume, becoming one of Ericsson’s largest core domestic suppliers. The cooperation results have been highly recognized by Ericsson’s global procurement center and technical R&D team.
During the long-term implementation of the project, our company fully leveraged the core advantages of local manufacturing enterprises: fast response speed, strong customization capability, and short service chain. We closely cooperated with Ericsson China’s 5G network construction and equipment iteration schedule, and rapidly responded to various needs such as product process optimization, structural upgrading, customized development, and urgent batch delivery.
This completely solved the previous industry pain points Ericsson faced when relying on overseas suppliers, including long supply cycles, slow iteration response, delayed after-sales maintenance, and high communication costs.
At the same time, localized large-scale mass production significantly reduced Ericsson’s component procurement costs, logistics costs, and supply chain management costs. It shortened equipment production and delivery cycles, helped Ericsson quickly capture opportunities in China’s new 5G infrastructure market, and effectively enhanced its core competitiveness in the Chinese communications market.
In addition, with solid product strength, the company ranked second in China’s communications aluminum die-casting component industry in 2025 with a market share of 15.1%. It has become a benchmark enterprise in China’s communications die-casting sector, with market recognition and industry influence continuing to lead among domestic peers.
The in-depth strategic cooperation with Ericsson is a landmark achievement in the localization and substitution of high-end communications aluminum die-cast structural components in China. It has high industry demonstration value and strategic industrial significance.
Previously, the core forming technologies and high-end mass production market for aluminum die-cast structural components used in Ericsson’s high-end base stations and RF units were long monopolized by leading overseas companies. Most domestic enterprises were limited by shortcomings in composite processes, insufficient thin-wall high-precision forming technology, and quality control systems that did not meet international standards. As a result, they were unable to enter the international high-end communications equipment supply chain. The field long faced industry pain points such as bottlenecks in high-end products and heavy dependence on imported supply chains.
Through long-term technological dedication, our company has successfully broken through a series of core technical bottlenecks, including multi-process composite forming, thin-wall high-precision forming, high-density defect-free die casting, and high-efficiency heat dissipation structure optimization.
The communications aluminum die-cast structural components independently developed and produced by our company fully match and even surpass imported overseas products in core indicators such as precision, strength, heat dissipation, stability, and weather resistance. This has completely broken the long-standing monopoly of overseas brands in the high-end communications die-casting field.
The 28.3% procurement share in Ericsson China, 15.1% industry market share, and second-place industry ranking fully demonstrate our company’s technical strength and large-scale supporting capability. These achievements mark that domestically produced high-end aluminum die-cast components for communications equipment now officially possess the mass-production and supporting capability to benchmark against international first-tier brands.
The successful implementation of this localized substitution not only helps Ericsson significantly optimize its supply chain system, reduce dependence on overseas imports, improve the autonomy and risk resistance of its China supply chain, reduce equipment production costs, and support its expansion into lower-tier domestic markets; it also greatly boosts confidence in localization across China’s communications component industry.
This project fills the technical gap in China’s high-end communications composite die-cast structural components and provides a mature reference model for similar domestic enterprises to overcome technical barriers and enter international high-end communications supply chains. It effectively promotes the upgrading of China’s communications aluminum alloy die-casting industry toward high-end, precision, and integrated development.
The Ericsson high-end communications aluminum die-cast structural component supply project is a core achievement of our company’s long-term focus on the precision communications die-casting field and its commitment to technological innovation and process iteration. It is also a typical successful case of high-end localization and substitution of domestic communications core components, breaking overseas technological monopolies and fully demonstrating the hard-core technical strength and supply chain value of local manufacturing enterprises.
In the future, our company will continue to focus on the core field of high-end aluminum alloy structural components for communications equipment. We will further increase R&D investment in composite process iteration, precision forming technology, and the application of new materials. We will continuously optimize product performance in lightweight design, high precision, high heat dissipation, and strong weather resistance, while further improving large-scale mass production capability, flexible customization capability, and rapid delivery service capability.
At the same time, we will continue to deepen our global strategic cooperation with Ericsson. Closely following the industrial layout of global 5G evolution, computing power networks, and 6G pre-research, we will continue to expand the supporting product categories and cooperation scale for high-end communications structural components. We will fully support the high-quality development of Ericsson’s global business and continuously empower the high-end, independent, and international upgrading of China’s communications component industry.
