Batch-to-Batch Quality Fluctuation Caused by Large Temperature Differences in the Curing Oven

The curing degree of products at different positions in the same batch is inconsistent. This problem directly affects the mechanical properties and surface quality of the product, and in severe cases leads to the scrapping of the entire batch of products.

(1) Process factors: uneven hot air circulation in the curing oven, this factor affects the product's '2079851475616104453 and final quality. (2) In terms of temperature parameters: temperature dead zones exist in the oven, temperature deviation directly affects the physicochemical state of the material and the reaction progress. (3) In terms of density distribution: excessive loading density hinders heat transfer, density differences reflect uneven densification in various parts of the product.

(1) Design optimization: optimize the hot air circulation system of the curing oven, combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (2) Implementation measures: regularly perform oven temperature distribution calibration, formulate a specific operation plan based on actual production conditions and verify the implementation effect. (3) Implementation measures: arrange products reasonably to avoid dense stacking., formulate a specific operation plan based on actual production conditions and verify the implementation effect. (4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

The core of the poor curing problem is that the chemical reaction conditions are not met, and the formula ratio and curing process parameters need to be precisely controlled.
