The Machining & Casting Applications
CNC aluminum profiles, featuring lightweight and high rigidity, serve as the core material for automation equipment frames. Typical applications include frames of automated production lines, robotic arm bases, and conveyor guide rail brackets. Through CNC high-precision cutting and drilling, they can accurately match the assembly holes of equipment, reducing subsequent debugging costs. Meanwhile, the corrosion resistance of aluminum profiles enables them to adapt to oily and dusty workshop environments, resisting deformation during long-term use and extending the service life of equipment.
Focusing on the demands for thermal conductivity and structural protection, CNC aluminum profiles are widely used in outer casings and internal supports of electronic devices. Representative products cover server chassis casings, heat dissipation chambers of new energy inverters, and borders of industrial control screens. CNC processing allows for the creation of complex heat dissipation grooves and buckle structures, which not only ensure the heat dissipation efficiency of electronic components but also protect internal circuits through one-piece molded casings, preventing interference from moisture and dust and adapting to various indoor and outdoor usage environments.
Driven by the demand for lightweight and energy-saving, CNC aluminum profiles have become a key material for new energy transportation equipment. Examples include battery pack casings of new energy vehicles—CNC milling is used to create sealing grooves and mounting holes, ensuring water and dust resistance for batteries—frames of electric motorcycles, and interior skeletons of rail transit carriages. The special-shaped cross-sections formed by CNC processing can accommodate the installation of seats and armrests, while reducing the overall weight of the carriage and lowering track load.
Aligning with the needs of consumer products for thin and light design and appearance texture, CNC aluminum profiles are applied to structural components of high-end consumer electronics and smart home devices. For instance, heat dissipation module brackets of laptops—CNC precision processing achieves ultra-thin wall structures with a thickness controllable at 1-2mm, adapting to the thin and light design of the device—casings of smart door locks, where CNC wire drawing and anodizing processes create a fine metallic texture while providing scratch-resistant and corrosion-resistant properties, and body frames of home projectors. Their lightweight design facilitates easy movement, and high-precision processing ensures the coaxiality of the lens and the body, improving projection image quality.
The Machining & Casting Advantages
For medium-to-large batch orders, this series delivers “low-cost blank forming paired with high-efficiency finishing”. Casting facilitates the rapid production of high-volume blanks, minimizing material waste. Meanwhile, standardized machining workflows shorten the per-unit processing cycle, further enhancing production efficiency.
Casting enables one-piece product formation, eliminating weak points like welds and splice joints—these are prone to fatigue cracking under long-term loads. Additionally, subsequent precision machining optimizes surface roughness (Ra ≤ 0.8μm), ensuring a tight fit between mating parts and thereby reducing the risk of wear and leakage.
It supports a diverse range of metal materials and enables customization of material performance based on application scenarios. For products demanding high strength, ductile iron or alloy steel is used for casting, combined with heat treatment and precision grinding processes—boosting hardness to HRC 50-60. For applications requiring lightweight and corrosion-resistant characteristics, aluminum alloy or stainless steel casting is adopted, paired with surface processing and anodizing/passivation treatments to improve rust protection. This versatility meets the material needs of industries including automotive, aerospace, marine, and industrial equipment.
Metal enclosures act as intrinsic heat sinks and provide robust electromagnetic interference (EMI)/radio frequency interference (RFI) shielding. This ensures the stable and reliable operation of electronic devices housed within.
