Look at the weight of the material.
The quality of the hinge is poor, and the cabinet door will be prone to be leaned forward and closed after a long time, loosening and sagging. Almost all major brands of cabinet hardware use cold-rolled steel, which is formed by one-step stamping, with a thick feel and smooth surface. Moreover, due to the thick surface coating, it is not easy to rust, is strong and durable, and has strong load-bearing capacity. Inferior hinges are generally made of thin iron sheet welding, which has almost no resilience. If it takes a long time, it will lose its elasticity and cause the door to close. Lax, even cracking.
