Q:Many domestic hinges will find their door panels sag soon after they are used When the door is closed, the two door panels will even touch each other, resulting in failure to close the door What s the reason?
A:Firstly, it is related to the raw materials. If the quality of the steel used is too poor, the hardness will not be enough, making it easier to cause deformation and sagging. Secondly, whether the key parts of the hinge, such as the connecting piece, spring piece, rivet and U-shaped nail, have received heat treatment, or even if there is heat treatment, but if the equipment is too poor, the same problem will occur. The purpose of heat treatment is to change the internal structure of the steel through high temperature, so that the steel becomes harder and more ductile. Just like the kitchen knife used in our family, whether the kitchen knife is easy to use, in addition to the relationship with the material, is related with the master's control of the fire when quenching. Under the conditions of too high temperature and too brittle steel, it is easy to fracture。 But if the temperature is low, the hardness will not be enough. However, the heat treatment equipment adopted by UTA is controlled by imported computer, which are divided into three processes: quenching, oil cooling and tempering. Each process is subdivided into several different stages of temperature controls, and even the cooling oil is also imported, ensuring the strength of each hinge.
Q:Now many bathroom cabinets use 12mm PVC door panel Do you have a hinge suitable for this kind of door panel?
A:As the normal drilling depth of hinge cup is at least 11.5mm, it can't be used on such a thin door panel naturally. It is recommended to use the general hinge of U200 series. They belong to the small hinge of 26 cups, and the drilling depth of the hinge cup is only 9.5mm, which can be used on the 12mm door panel. For the small door panel of the bath cabinet, the small hinge can show its delicate bearing capacity.
Q:Now many solid wood cabinets often use 20 mm and 25 mm thick side plates Currently, the ordinary full-cover hinge is often unable to adjust to the required cover door Does UTA have such hinge that can solve this problem?
A:Yes, when the side plate is 20 mm thick, the full cover hinge of the general type and hydraulic type can cover up to 19.5 mm at most, which can fully meet the customer's demand of covering doors; while when the side plate is 25 mm thick, selecting the thick door hinge can solve this problem, but on the premise that the D value of drilling of the door plate hinge cup must be increased to 11 mm ~ 12 mm (normally, it is 4 ~ 5 mm).
Q:If the door seam is too large after installing the hinge, how to deal with it?
A:There are many reasons for door seam, of course, there are also many solutions. One is to adjust the adjustment screw above the hinge, so that the door seam will change accordingly, but this method will also change the size of the cover door. The other is to adjust the base screw behind the hinge, so as to adjust the door seam. At present, most hinges are open or closed adjustable base screws, which need to be adjusted and locked after loosening all screws on the door panel. Our company provides base screws for fine adjustment, which can solve the door seam without moving the door panel directly through adjusting the screw.
Q:Is there any difference between the hinge used for 16mm door panel and 18mm door panel?
A:In general, the hinge doesn't change much. Our company will provide bases with different heights according to the needs of different customers, so that we can achieve the door size required by customers. At present, our company has three kinds bases of different heights, namely, H = 0, h = 2, and h = 4. H = 0 is suitable for the cover door of more than 18mm, H = 2 is suitable for the cover door of 16mm. When you purchase the hinge, you shall consult for the appropriate base height.
Q:Why does some door panels fail to be closed after using domestic hydraulic hinges?
A:It is mainly caused by the oil pressure rod in the hinge. There are plastic pistons in the oil pressure rod, and the piston has two small holes. One is the distribution valve to change the direction of oil supply, and the other is the overflow valve to regulate the limited pressure of the system. If there is a small amount of residual impurities in the hole and the environment of hinge production is too messy, it will block the hole and cause jam;Another situation is that the oil quality of the oil bar itself is not good or it is easy to leak oil, which will cause the door panel to fail to close. Our production environment is qualified by ISO every year, and the control of the oil pressure bar itself is in line with international standards, so we can use our hinge in a safe manner.
Q:When purchasing hinges, should they be equipped with four-hole base or two-hole base?
A:In principle, there is no big difference, but the four-hole base is relatively more fixed because it can be locked with four wood screws. For two-hole base, unless the door panel is too heavy or too large, there will be basically no problem of fixation, and it will bring about a much better visual experience, which is also currently dominating the market in Europe and the United States. UTA can provide both for customers according to their needs ..
