On 20 May 2025, Huawei's latest release of the world's largest folding screen computer - HUAWEI MateBook Fold Extraordinary Master triggered heated discussions in the industry. (hereinafter referred to as ‘Jin Cheng Precision’), with its leading technology in the field of aluminium alloy die casting and precision machining, summarized the key structural components that can provide Huawei with support advantages, showing the breakthrough strength of the domestic supply chain in the field of high-end manufacturing. High degree of compatibility between technical advantages and Huawei's needs 1. High-end aluminium alloy die-casting process: the market share of aluminium alloy thin-walled parts manufacturing ranks first in China, and it has accumulated rich experience in the field of communication and automotive parts. We have introduced world-class die-casting equipment, including a die-casting machine with a clamping force of 4,000 tonnes, which, combined with vacuum die-casting and mould temperature control technology, can produce ultra-thin die-castings with a thickness as low as 0.8mm, meeting the stringent requirements of lightweight and structural strength for folding screen equipment. 2. Precision Machining and Surface Treatment Capability: With more than 600 CNC machining centres and automated spraying and plating production lines, we can complete high-precision machining and nano-scale surface treatment to ensure the flatness and scratch-resistant performance of the shell. For example, through the self-developed spraying process, the surface reflectivity of the product can be reduced to less than 2%, which perfectly matches the anti-glare requirements of folding screen computers. Innovative Material and Structure Design 1. Balancing lightweight and toughness Huawei requires that the structural components of the middle frame should take into account the ultra-thin design (the unfolded thickness is only 7.3mm) and impact resistance. Jin Cheng Precision was able to use aerospace-grade aluminium alloy materials, combined with optimized topology design, to reduce the weight of the case by 30% while increasing the flexural strength to twice that of traditional materials. Integration moulding of complex structural parts For the high-precision needs of the hinge area of the folding screen, Jincheng Precision can apply metal injection moulding (MIM) technology to control the tolerance within 0.01mm, ensuring the smoothness and durability of the hinge opening and closing. In addition, the zirconium-based liquid metal material developed is three times stronger than traditional steel, providing reliable support for the ultra-thin fuselage. Technical response speed and joint R&D capability are the key to cooperation. Jin Cheng Precision takes only 6 weeks from sample delivery to mass production, which is 40% shorter than the industry's average cycle time, and can help maintain the market debut advantage. In the context of global competition for folding screen devices, JC Precision will become the industry benchmark, transforming from ‘scale advantage’ to ‘quality innovation’, and promoting China's high-end precision manufacturing to new heights.
