Case Demonstration of Sinbo Precision Mechanical's Powder Metallurgy Production Capacity
In the field of powder metallurgy production, Sinbo Precision Mechanical has always demonstrated strong production capabilities with excellent technology and innovative processes. The following actual cases comprehensively present the company's extraordinary strength in powder metallurgy production.
Efficient Production of Complex - structured Parts
Project Requirements
A high - end machinery manufacturing enterprise required a batch of parts with complex structures and extremely high precision requirements. Traditional manufacturing processes were difficult to meet the dual demands of complex shapes and high performance. Sinbo Precision Mechanical, with its profound accumulation in the field of powder metallurgy, undertook this project.
Production Process
- Powder Preparation Stage: Sinbo Precision Mechanical adopted an advanced process combining atomization and reduction to precisely control the particle size and composition of metal powders. For example, for the key iron - based alloy powders in this project, by optimizing atomization parameters, the particle size distribution of the powders was ensured to be uniform, with an average particle size of less than 50 microns, laying a solid foundation for subsequent forming. At the same time, the impurity content in the powder was strictly controlled to ensure a purity of over 99.9%, greatly improving the stability and reliability of the material.
- Implementation of Forming Process: For the complex structures of the parts, a combination of precision die pressing and powder injection molding technologies was comprehensively used. During precision die pressing, high - precision molds were used, and the pressing pressure was precisely controlled at 800MPa to ensure that the basic shape and dimensional accuracy of the parts were controlled within ±0.05mm. For some parts with fine internal structures, powder injection molding was used. By optimizing injection process parameters, such as controlling the injection temperature at 180°C and the injection pressure at 150MPa, the accurate replication of complex structures was successfully achieved, and the molding yield rate was as high as 98%.
- Guarantee of Sintering Process: An advanced process combining vacuum sintering and liquid - phase sintering was adopted. In the vacuum sintering stage, the sintering temperature was raised to 1200°C to effectively remove gases and impurities between powder particles and promote atomic diffusion between particles. During the subsequent liquid - phase sintering process, the amount of liquid phase generated and the sintering time were precisely controlled. Maintaining at 1350°C for 2 hours, the material was fully densified. The density of the final product reached over 98% of the theoretical density, significantly improving the strength and hardness of the parts.
Project Results
Sinbo Precision Mechanical successfully delivered high - quality complex - structured parts, and the product performance fully met the strict requirements of the customer. In practical applications, these parts demonstrated excellent wear resistance and stability, greatly extending the service life of the equipment and receiving high praise from the customer. This project not only demonstrated the company's strong ability in the powder metallurgy production of complex - structured parts but also further consolidated Sinbo Precision Mechanical's leading position in the industry.
Stable Supply of a Large Number of High - performance Parts
Project Background
A well - known automotive manufacturing enterprise planned to expand its production scale and urgently needed a stable supply of a large number of high - performance automotive engine parts, with extremely high requirements for the strength, wear resistance, and consistency of the parts. Sinbo Precision Mechanical won the cooperation opportunity for this project with its mature powder metallurgy production system.
Production Measures
- Large - scale Powder Preparation: To meet the needs of large - scale production, Sinbo Precision Mechanical optimized the powder preparation process and introduced an automated production line. When preparing copper - based alloy powders, through the automated control system, the atomization gas pressure and flow rate were precisely adjusted to ensure that the particle size and composition of each batch of powder were highly consistent. The daily powder output could reach 5 tons, and the quality stability was controlled within a very small range, providing a reliable raw material guarantee for large - scale production.
- Optimization of Forming Process: In the forming process, multi - station precision die pressing and automated powder injection molding equipment were used. The multi - station mold could simultaneously press multiple parts, greatly improving production efficiency. At the same time, through a real - time monitoring and feedback system, parameters such as pressing pressure and injection speed were dynamically adjusted to ensure the forming accuracy and quality of each part. During large - scale production, the dimensional deviation of the parts was controlled within ±0.03mm, and the forming efficiency was increased by 30% compared with the traditional process.
- Innovation in Sintering Process: A continuous vacuum sintering furnace and an efficient liquid - phase sintering process were developed for the characteristics of large - scale production. The continuous vacuum sintering furnace achieved continuous sintering of parts, improving production efficiency while ensuring the uniformity and stability of the sintering temperature. During the liquid - phase sintering process, by optimizing the sintering curve, the sintering cycle was shortened from the original 8 hours per furnace to 6 hours, and the product quality was not affected, ensuring the consistency and stability of product performance under large - scale production.
Project Results
Sinbo Precision Mechanical successfully achieved the stable supply of a large number of high - performance automotive engine parts, with a monthly delivery volume of over 100,000 pieces. The products performed excellently in automotive engines, effectively improving the power performance and fuel economy of the engines, and were recognized and trusted by the automotive manufacturing enterprise in the long term. This cooperation fully demonstrated Sinbo Precision Mechanical's outstanding ability in large - scale powder metallurgy production and set a model for efficient and stable production in the industry.
Through the above two typical cases, the comprehensive advantages of Sinbo Precision Mechanical in powder metallurgy production capacity are clearly demonstrated. Whether it is the fine manufacturing of complex - structured parts or the stable supply of a large number of high - performance parts, the company can rely on advanced technologies and processes to provide customers with high - quality and efficient solutions.
