We provide complete design and manufacturing of metal chassis, cabinets, and supporting installation and fixing structural components in various materials through CNC machining technology.
Chassis and its installation components
We provide CNC metal processing chassis, high-precision metal cutting process design, adopting an integrated structural framework and modular design concept, compatible with five axis linkage machining centers, turning and milling composite machine tools and other equipment. The main body is made of aluminum or aluminum alloy composite material, which has undergone aging treatment to eliminate internal stress and ensure long-term operational stability. It can be applied to fields such as aerospace, automotive manufacturing, and mold industry.
Parameter | Pure Aluminum (1A30) | Aluminum Alloy (6061-T6) |

Shielding effectiveness (dB) | 30-67 (fast drop in high frequency range) | Good (general EMI shielding) |
CNC cabinet processing and welding
We provide CNC sheet metal processing for cabinets made of various metal materials. Among them, the color coated zinc steel plate is formed with a zinc iron alloy layer through electroplating technology, which combines the mechanical strength of steel with the anti-corrosion properties of the zinc layer. Aluminum alloy, represented by models such as 6061-T6, has become the preferred choice for precision equipment casings due to its lightweight, high thermal conductivity, and excellent machinability. These two materials demonstrate differentiation advantages in CNC sheet metal processing: color coated zinc steel plates are more suitable for scenarios that require electromagnetic shielding or outdoor weather resistance, and their surface color coatings can provide additional protection; Aluminum alloy is processed with complex structures through CNC milling, with a tolerance accuracy of ± 0.1mm, meeting the dual requirements of heat dissipation and lightweight for industrial control equipment.

Weight | 1.5-3kg | Aluminum substrate+copper tube | |
Metal Substrate
We can provide copper or aluminum materials in various specifications and sizes as substrates for PCB or other modules that require fixing or heat dissipation. Its main technical feature is its ultra-high thermal conductivity, such as copper having a thermal conductivity coefficient of 398 W/(m · K); Excellent high-frequency performance, suitable for high-frequency circuits (such as 5G base stations and RF equipment), reducing signal loss; Matching the coefficient of thermal expansion, such as copper’s CTE (17 ppm/℃) being closer to silicon chips (3 ppm/℃), reduces thermal stress and improves reliability. Widely used in high-power density devices such as AI server GPUs, laser drivers, high-frequency switching power supplies, base station RF modules, microwave circuits, etc.
