Product sticks to the mold during sintering

PTFE sticks to the mold when sintered in the mold. This problem is relatively common in sintering molding production and needs to be comprehensively analyzed and solved from multiple aspects of material, process, and equipment.

(1) Mold aspect: The rough mold surface provides mechanical interlocking; the mold structure or state directly affects the flow and molding of the material in the cavity. (2) Mold aspect: PTFE locally penetrates into the micropores of the mold surface at high temperature; the mold structure or state directly affects the flow and molding of the material in the cavity. (3) Process factor: Lack of demolding isolation measures; this factor affects the '2079851475616104453 and final quality of the product.

(1) Material selection: Use aluminum foil or PTFE release film to isolate the product from the mold, establish material selection evaluation standards, and determine the optimal plan through comparative tests. (2) Formulation adjustment: Chrome-plate and polish the mold surface to reduce roughness, adjust gradually and verify the effect to ensure that other performance indicators of the product are not affected. (3) Implementation measure: Adopt free sintering (not relying on the mold)., formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (4) Preventive measure: Establish a sound process control standard and quality inspection system, and regularly review process data for continuous optimization.

This problem needs to be comprehensively analyzed from multiple dimensions of material, process, equipment, and operation, and solved by systematically optimizing process parameters and the quality control system.
