Excessive Product Hardness/Excessive Brittleness

The product hardness is excessive and lacks toughness, with poor impact resistance. The decline in mechanical properties is usually only discovered during the product's service or inspection stage, and is hidden. This defect significantly reduces the mechanical properties and service life of the product and may cause early failure of the product in service.

(1) In terms of formula control: excessive amount of curing agent causes too high a crosslink density, component ratios deviating from design values lead to abnormal chemical reactions or physical states. (2) Process factors: lack of toughening components in the formula, this factor affects the product's '2079851475616104453 and final quality. (3) Process factors: excessive post-curing, this factor affects the product's '2079851475616104453 and final quality.

(1) Process control: precisely control the curing agent metering to reduce excess, establish an online monitoring mechanism, set upper and lower parameter limits, and implement alarm management. (2) Formula optimization: add toughening agents or flexible resin modification, determine the optimal addition amount through small-batch tests and verify its impact on the comprehensive performance of the product. (3) Design optimization: optimize the post-curing temperature and time., combine process simulation analysis or trial mold verification to continuously iterate and improve the design plan. (4) Preventive measures: establish a complete process control standard and quality inspection system, and regularly review process data for continuous optimization.

The core reason for insufficient mechanical properties is inadequate material bonding or degradation; the sintering/curing process needs to be optimized and raw material quality controlled.
