High precision Powder metallurgy technology can achieve very high dimensional accuracy and surface finish, directly producing components close to the final shape, reducing subsequent processing procedures, improving production efficiency, and also ensuring the consistency and interchangeability of components. For example, components such as elevator guide rails and traction wheels can precisely control their size and shape through powder metallurgy technology. Ensure the operational accuracy and stability of the elevator.
High material utilization rate: In the powder metallurgy process, the material loss is very small, and almost all powder raw materials can be transformed into finished components. Compared with traditional cutting processing methods, the material utilization rate can be significantly increased, reducing production costs.
Complex-shaped components can be manufactured: This process can produce components with complex shapes that are difficult to achieve through traditional forging or mechanical processing methods, such as elevator parts with complex inner cavities and irregular cross-sections. This provides greater flexibility in the design of elevator components and can meet the special requirements of different elevator models and functions.
Excellent mechanical properties: After proper heat treatment and post-processing, powder metallurgy components can achieve excellent mechanical properties, such as high strength, high hardness, wear resistance and corrosion resistance, etc. For instance, elevator braking components manufactured by powder metallurgy can withstand high loads and frequent braking operations, ensuring the safe and reliable operation of the elevator.
Self-lubricating performance: By adding an appropriate amount of solid lubricants (such as graphite, etc.) to the powder, powder metallurgy components can be made to have self-lubricating performance, reducing friction and wear during operation, lowering noise, improving the comfort of elevator operation, and also reducing the reliance on the lubrication system and maintenance costs.
High cost-effectiveness: Although the mold cost of powder metallurgy is relatively high, in large-scale production, due to the reduction of subsequent processing procedures, high material utilization rate and high production efficiency, the production cost of individual components is reduced, making it have good cost-effectiveness.
