    • A method for improving performance of a cup lid (100) and a cup lid (100) manufactured by the method are disclosed. The method includes: manufacturing a TPU handle (109) with mounting holes (113), a stainless steel outer cover (105), a stainless steel top plate (106), a PP plastic inner ring (104) with mounting snap positions (112), a PP plastic main body cover (101), a PP plastic honeycomb (103), a stainless steel vacuum piece (102), a silicone ring (107), and a sealing ring (108); setting connecting positions on the PP plastic main body cover (101), using bridge connectors (110) to guide through the mounting snap positions (112), the connecting positions (111) and the mounting holes (113); pressing the TPU handle (109), the stainless steel outer cover (105) and the PP plastic inner ring (104) against the PP plastic main body cover (101) using the bridge connectors (110), so that a middle part of the bridge connector (110) is restricted by a bottom end of the connecting position (111) and a top end of the mounting snap position (112) to limit the position of the PP plastic inner ring (104). The product adopts a manufacturing process with mechanical snaps, the stainless steel vacuum piece (102) inside is formed through an injection molding process, thus the texture and durability of the product are ensured. The handle is made of TPU material, and its texture, strength and the steel pins demonstrate the texture of the product, as well as improve product quality.
