High wear rate (insufficiently sintered)

PTFE seals or wear-resistant parts wear too quickly in use. 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) Temperature parameter aspect: Insufficient sintering temperature or time; temperature deviations directly affect the physical and chemical state of the material and the reaction process. (2) Raw material characteristic aspect: Insufficient fusion between particles; the physical characteristics of the powder directly affect the preforming and sintering quality. (3) Process factor: Excessively large porosity; this factor affects the '2079851475616104453 and final quality of the product.

(1) Design optimization: Optimize the sintering process to ensure full fusion of particles, combine process simulation analysis or trial mold verification, and continuously iteratively improve the design plan. (2) Formulation adjustment: Reduce the porosity to the minimum, adjust gradually and verify the effect to ensure that other performance indicators of the product are not affected. (3) Equipment maintenance: Check the molecular weight and particle size distribution of the raw material., formulate regular inspection and maintenance plans to ensure the equipment is in the best working condition. (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.
