• 1. Material: Hinges are available in various materials such as stainless steel, stainless iron, iron, zinc alloy, etc. Here, I recommend using "304 stainless steel" for hinges as it can ensure long-lasting use of cabinet doors. Currently, zinc alloy hinges have been phased out of the market due to material aging and brittleness. Although they are cheaper, their quality cannot be guaranteed, and rust can be troublesome. Moreover, replacing hinges is not only expensive in terms of labor costs but also time-consuming and labor-intensive.

Specifications: Hinge specifications are mainly divided into three types: straight arm, medium bend, and large bend. Observant individuals may notice that the connecting arm is crucial. The straight arm has no curvature, the medium bend has a moderate curvature, and the large bend has the greatest curvature.

材质：铰链材质有不锈钢，不锈铁，铁，锌合金等材质，建议大家选用“304不锈钢”，可以长久保持柜门的使用。目前，锌合金材料的铰链已退出市场，因为材料容易老化，脆化。虽然便宜，但是质量没法保证，生锈就很麻烦，更换铰链的人工费不仅贵，而且费时费力。

2. Function: Straight, medium, and large bend hinges can also be referred to as full overlay, half overlay, and no overlay hinges. The terms "overlay" in full overlay, half overlay, and no overlay refer to how much the cabinet door covers the cabinet stile. In the case of full overlay, it means that when the cabinet door is closed, it completely covers the stile. Half overlay means that the cabinet door only covers half of the stile, and this is usually used in the middle section of the cabinet where both the left and right sides have cabinet doors. Therefore, half overlay hinges are the most commonly used hinges in practical applications. The large bend or no overlay indicates that the cabinet door does not cover the stile, and this is usually used on the sides of the cabinet, such as a shoe cabinet.

功能：铰链规格主要分为三种，分别为直臂，中弯，大弯。细心的朋友可以发现，这个连接臂是关键，直臂没有任何的弯曲，中弯弯度适中，而大弯弯度是最大的。

直，中，大弯铰链又可被称为全盖，半盖，无盖铰链。全盖、半盖和无盖这些词语中的“盖”，指的是柜门盖住柜子立板的多少，如果是全盖，那么意味着柜门关闭后，完全盖住立板。半盖意味着柜门只盖住了立板的一半，这种通常用到柜子的中间部位，比如左右侧都是柜门，那么就需要半盖的铰链，这种铰链在实际应用当中也是使用量最大的。大弯也就是无盖，指的的是柜门不会盖住立板。这种通常也是用到柜子的两边，比如鞋柜

In addition, when selecting hinges, it is also important to consider whether they come with a damping mechanism. Hinges with a damping mechanism are better than ordinary hinges as they are smooth, silent, and beneficial to the cabinet, without startling others. As for the factor of detachable hinges, there is no need to deliberately dwell on it. Detachable hinges refer to the ability to separate the base from the hinge, and this feature is only for the convenience of installation and maintenance by professionals.

除此之外，选购铰链还要看是否带阻尼器。带阻尼器的铰链相比普通铰链带阻尼器的铰链更好些，柔顺无声，对柜体有好处，并且不会吓着他人。至于脱卸铰链这个因素到不用刻意的纠结，脱卸就是指的底座可以和铰链分开，而这一功能仅为了方便师傅安装以及维修。
