Density stratification rings appear in centrifugal casting (annual ring patterns)

Concentric ring-shaped density difference textures appear in the product cross-section. Density differences are evident between different parts of the product, affecting the overall performance consistency of the product.

(1) Process factor: Intermittent feeding leads to poor bonding at multiple filling interfaces, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: The centrifuge speed fluctuates periodically, This factor affects the '2079851475616104453 and final quality of the product. (3) Process aspect: Uneven pressure transmission or insufficient holding pressure causes densification differences among parts. (4) Material aspect: Filler sedimentation or composition segregation causes local density abnormalities. (5) Operation aspect: Uneven feeding or improper filling sequence.

(1) Formulation optimization: Adopt continuous or one-time addition, Determine the optimal addition amount through small-batch tests, and verify the effect on the overall performance of the product. (2) Implementation measure: Ensure the centrifuge drive system runs at a stable speed., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (3) Process optimization: Increase the preforming pressure and maintain sufficient holding time to ensure uniform compaction of all parts. (4) Operation improvement: Optimize the feeding method to ensure uniform filling, and use vibration-assisted feeding if necessary. (5) Preventive measure: Establish a raw material batch inspection system, regularly sample product density and mechanical properties, and establish quality trend analysis.

The essence of uneven density is inconsistent distribution or densification of the material during the '2079851475616104453; it is necessary to optimize the feeding method and pressure transmission.
