The present invention relates to the field of polymer materials technology, specifically concerning a method for enhancing the crystallization temperature of polyamide. The method for increasing the crystallization temperature of polyamide comprises the following steps: adding nucleating agent in proportion to a polyamide aqueous salt system for polymerization, extrusion, cooling, drying, and pelletizing; or adding nucleating agent and polyamide in proportion to a twin-screw extruder for melting, extrusion, cooling, drying, and pelletizing. By adding a special nucleating agent, the present invention increases the crystallization temperature and crystallization rate of polyamide. This shortens the molding cycle, improves production efficiency, enhances crystal structure, boosts the mechanical and optical properties of the product, increases the heat deflection temperature, improves dimensional stability, and reduces post-shrinkage.
