According to the engineer, stainless steel is stronger than steel nickel plated material and iron nickel plated chromium material in hardness, but inferior to steel nickel plated material in toughness. The choice of purchase should be based on the situation. Compared with the two, iron nickel plated chromium hinges are also very common in the current market, and the price is relatively low, but consumers should be reminded that kitchen appliances such as cabinets are always in a humid environment, Therefore, iron hinges are prone to rust. Even if other metals are plated on the iron surface, iron hinges will still rust if there is a problem with electroplating, affecting the normal use of the hinge and even the service life of the hinge.
Although the hinge is small, there are many problems
The problem caused by the hinge * * The intuitive performance is to cause the cabinet door to droop. The reporter learned from the Beijing Construction Hardware Plumbing Product Quality Supervision and Inspection Station that there are three main reasons for cabinet door sagging, * * the hinge itself is not up to standard. Hinges in the inspection station are often subject to professional tests in terms of vertical static load, horizontal static load, operating force, durability, subsidence, corrosion resistance, etc. If the tested products are unqualified, it is often easy to break the hinge in use, resulting in falling off, and deformation in use, resulting in poor closing. In the purchase process of consumers, businesses often do not show such testing reports.
The second reason is that the material quality of the door leaf and frame is not up to the standard, which makes the hinge easy to fall off. However, the staff of the inspection station told the reporter that the problem in this area * * is that it causes the deformation of the door body, and then affects the normal use of the hinge. The third is the installation problem. Ordinary professional installers rarely have installation problems. If they install by themselves or the installers are not skilled, they will have deviation during installation, resulting in inaccurate hinge installation position, which will not only lead to problems such as cabinet door sagging, but also affect the hinge itself.
In addition to the above three reasons, the reporter learned from the Beijing Wood Furniture Quality Supervision and Inspection Station that in addition to the material and installation problems, there are also some factors that can cause problems with the hinge, such as the spring in the hinge. The staff of the inspection station told the reporter that the current national standard for hinges in China only provides * * low standards for the overall performance of the product, such as being able to open tens of thousands of times, while there is no provision for parts beyond the national standard, such as the performance of springs
