Foreign Matter/Impurity Incorporation

Unwanted solid particles, fibers, and other foreign matter appear inside or on the surface of the product. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) Process factors: impurities mixed into the raw materials, this factor affects the product's '2079851475616104453 and final quality. (2) In terms of operation management: poor cleanliness of the operating environment, human factors cause deviations in process parameter execution. (3) In terms of the mold: incomplete cleaning inside the mold, the mold structure or condition directly affects the flow and molding of the material in the cavity.

(1) Material selection: sieve or filter raw materials before use, establish material selection evaluation standards and determine the optimal plan through comparative tests. (2) Implementation measures: keep the operating area clean and dust-free, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Material selection: thoroughly clean the mold cavity before each use., establish material selection evaluation standards and determine the optimal plan through comparative tests. (4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of materials, processes, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
