Corrosion of Mold Materials by Casting Material

The casting liquid reacts chemically with the mold, causing corrosion of the mold surface. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of materials, processes, and equipment.

(1) In terms of the mold: the mold material is not resistant to the chemical medium of the casting liquid (such as epoxy-amine systems corroding aluminum alloys), the mold structure or condition directly affects the flow and molding of the material in the cavity. (2) Process factors: failure of release agent protection, this factor affects the product's '2079851475616104453 and final quality. (3) In terms of materials: fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) In terms of the process: control deviations of key process parameters cause the '2079851475616104453 to deviate from optimal conditions. (5) In terms of equipment: equipment precision and maintenance status affect the stable execution of process parameters.

(1) Material selection: choose corrosion-resistant mold materials (such as chrome plating, stainless steel), establish material selection evaluation standards and determine the optimal plan through comparative tests. (2) Material selection: use a release agent with high chemical resistance, establish material selection evaluation standards and determine the optimal plan through comparative tests. (3) Equipment maintenance: check the integrity of the release agent before feeding., formulate a regular inspection and maintenance plan to ensure the equipment is in optimal working condition. (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.
