Dongguan Sinbo Precision, an Outstanding Model in Aluminum - Magnesium Alloy Parts Processing

Case of Aluminum - Magnesium Alloy Parts Processing by Dongguan Sinbo Precision

In the precision manufacturing industry, aluminum - magnesium alloys have become the material of choice for many high - end products due to their excellent properties, such as low density, high strength, and good corrosion resistance. Dongguan Sinbo Precision, as a leader in the industry, has demonstrated outstanding technical strength and rich experience in the processing of aluminum - magnesium alloy parts, successfully creating high - quality customized part solutions for multiple industries.

1. Case of Complex Aviation Parts Processing

The aviation industry has extremely strict requirements for the precision and quality of parts. Sinbo Precision once undertook a project to manufacture key aluminum - magnesium alloy parts for a new aircraft engine. The part has a complex structure, with numerous thin - walled sections, deep holes, and irregular curved surfaces. The dimensional accuracy requirement reaches ±0.005mm, and the surface roughness needs to be controlled below Ra0.4μm.

Facing these challenges, Sinbo Precision formed a special team composed of senior engineers and technical experts. In the processing technology planning, the team adopted advanced five - axis 联动 CNC machining technology. Through precise programming, the tool can move flexibly in a complex space, ensuring precise processing of all parts of the part. For the thin - walled parts, a special cutting parameter optimization strategy was used to effectively avoid part deformation caused by excessive cutting force while ensuring processing efficiency. In the deep - hole processing, customized high - precision deep - hole drills were used, combined with a high - pressure cooling system, which not only improved the chip removal efficiency but also ensured the smoothness and straightness of the hole wall.

In addition, to ensure the corrosion resistance and fatigue strength of the parts, Sinbo Precision carried out surface strengthening processes such as anodizing and aging treatment on the processed parts. After strict quality inspection, the final delivered parts exceeded the customer's expectations in all performance indicators, helping the customer's new engine successfully pass the rigorous flight test and winning a good reputation in the aviation market.

2. Case of High - End Electronic Equipment Parts Processing

With the development of electronic equipment towards miniaturization, lightweight, and high - performance, the requirements for the precision and integration of internal parts are getting higher and higher. Sinbo Precision cooperated with a well - known electronics brand to manufacture aluminum - magnesium alloy casings and internal structural parts for its new tablet computer. The customer required that the casing not only be lightweight and sturdy but also have excellent heat dissipation performance and electromagnetic shielding effect. The internal structural parts need to achieve high - precision assembly to ensure the stable operation of electronic components.

Sinbo Precision used self - developed precision molds and advanced die - casting processes to successfully manufacture aluminum - magnesium alloy casing blanks with thin walls and extremely high dimensional accuracy. In the subsequent processing, through precision CNC milling and grinding processes, the surface flatness and assembly dimensions of the casing were finely controlled, with the flatness error of the casing less than ±0.01mm and the assembly gap controlled within ±0.02mm. To improve heat dissipation performance, a special heat - sink fin structure was designed and processed on the surface of the casing. By optimizing the shape and layout of the fins, the heat - dissipation area was effectively increased, and the heat - dissipation efficiency was improved. For the electromagnetic shielding requirement, surface treatment technologies such as electroless nickel plating were used to endow the casing with good electromagnetic shielding ability without affecting the appearance and mechanical properties.

For the internal structural parts, Sinbo Precision used micro - processing technology to achieve high - precision processing of small holes and fine structures. Through a strict quality control system, from the inspection of raw materials to the real - time monitoring of each processing process and then to the comprehensive inspection of finished products, the quality stability and reliability of the internal structural parts were ensured. The final delivered products helped the customer's tablet computer stand out in the market with its lightweight, high - performance, and good heat - dissipation and electromagnetic shielding performance, and the sales volume increased significantly.

3. Strict Quality Control and Continuous Innovation

Sinbo Precision deeply understands that quality is the lifeblood of the enterprise. In the process of aluminum - magnesium alloy parts processing, a complete and strict quality control system has been established. The company is equipped with advanced testing equipment, such as high - precision coordinate measuring machines, electron microscopes, and spectrometers, to comprehensively and accurately detect the composition of raw materials, the dimensional accuracy of parts, surface quality, and micro - structure. Each batch of products has to go through multiple strict quality inspection procedures. Only when all indicators meet or exceed customer requirements and industry standards will the products be released.

At the same time, Sinbo Precision always adheres to technological innovation and continuously invests resources in research and development and process improvement. The company has established long - term cooperative relationships with many well - known universities and scientific research institutions to jointly carry out cutting - edge technology research and talent cultivation. By continuously introducing new technologies and processes, such as laser processing and additive manufacturing, and organically combining them with traditional processing technologies, the processing precision, efficiency, and quality of aluminum - magnesium alloy parts are continuously improved to meet the increasingly diverse and personalized needs of customers.

With its outstanding performance in the field of aluminum - magnesium alloy parts processing, Dongguan Sinbo Precision has won the trust and long - term cooperation of many domestic and foreign customers and has become an important force promoting the wide application of aluminum - magnesium alloys in the field of precision manufacturing.
