Insufficient tensile strength

The tensile strength of the product is significantly lower than that of normal sintered parts. The decline in mechanical properties is usually discovered only during the service or inspection stage of the product, and is concealed. This defect significantly reduces the mechanical properties and service life of the product, and may cause early failure of the product in service.

(1) Raw material characteristic aspect: Insufficient sintering results in no effective connection formed between particles; the physical characteristics of the powder directly affect the preforming and sintering quality. (2) Material stability aspect: Over-sintering causes degradation of polymer molecular chains; molecular chain breakage causes irreversible decline in material performance. (3) Process factor: The molecular weight of the raw material is relatively low; this factor affects the '2079851475616104453 and final quality of the product.

(1) Implementation measure: Ensure sufficient sintering temperature and time, formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (2) Implementation measure: Avoid the sintering temperature exceeding the standard, formulate specific operation plans in combination with actual production conditions, and verify the implementation effect. (3) Material selection: Select powder raw materials with suitable molecular weight., establish material selection evaluation standards, and determine the optimal plan through comparative tests. (4) Preventive measure: Establish a raw material batch inspection system, regularly sample and test product density and mechanical properties, and establish quality trend analysis.

The core cause of insufficient mechanical properties is insufficient material bonding or degradation, and the sintering/curing process needs to be optimized and the raw material quality controlled.
