Materials and Sizes
Half Moon Magnetic Door Stop is made of a variety of high-quality materials. Common materials for the main cover include Satin Stainless Steel, Zinc Alloy, and Aluminum Alloy with a diameter of 44 mm and a height of 25 mm, with rubber cushions. Taking Satin Stainless Steel as an example, its thickness is uniform and it has been finely processed to ensure the overall solidity and durability of the product. In terms of size design, the specifications of 44 mm in diameter and 25 mm in height are the optimal sizes calculated after a lot of ergonomics and actual usage scenario data. Such a size ensures that the product can provide sufficient magnetic force and stability, and will not be bulky due to its large size, affecting the aesthetics. The rubber part is about 3 mm thick and fits tightly to the metal body. It can provide just the right buffer at the moment when the door stopper contacts the door, avoiding damage to the door and door stopper caused by rigid collision.
Surface treatment process
The door stopper has a variety of surface treatment processes such as Black PVD, Matt Antique Brass - PVD, Polished Brass / PVD, Polished Stainless Steel, Satin Brass PVD, Satin Stainless Steel, etc. Taking the Black PVD process as an example, its surface hardness can reach more than HV3000. This hardness index is the average value obtained by multiple measurements using professional hardness testing instruments in accordance with national standard test methods. Compared with ordinary electroplating processes, the surface treated with PVD process is more wear-resistant and scratch-resistant, and can maintain color and texture for a long time. In actual use, even after long-term frequent touching and wiping, there will be no obvious scratches and wear on the surface of the door stopper, and it will always be as good as new.
Antioxidation performance
In the humid environment test, the Half Moon Magnetic Door Stop made of Satin Stainless Steel showed excellent antioxidation properties. After the door stopper was placed in an environment with a relative humidity of more than 90% for 72 hours, it was found that there was no obvious rust through professional corrosion detection equipment and naked eye observation. This is because Satin Stainless Steel contains a high proportion of chromium, which can form a dense oxide film on the surface. This oxide film is like a solid barrier that can effectively prevent moisture and oxygen from corroding the internal metal and prevent rust. In actual application, even in coastal areas or basements that are in a humid environment for a long time, this door stopper can ensure long-term stable use, and its service life can be extended by 2-3 times compared with door stops made of ordinary materials.
Strong suction
Half Moon Magnetic Door Stop with built-in strong magnets has a suction force of 30-50 Newtons. This suction data is the average value obtained by multiple tests of the door stopper and a standard iron door panel with a thickness of 40 mm and a material of Q235 at a standard indoor ambient temperature of 25℃ and a humidity of 50% using a professional magnetic test instrument. In actual use, the suction force of 30-50 Newton can easily hold an ordinary wooden door weighing 5-8 kg. For example, for a solid wood composite door weighing 6.5 kg, the door stopper can firmly fix it on the wall without being displaced by airflow or slight vibration. This powerful suction ensures that the door leaf can stop accurately at the designated position after opening, which brings convenience to users and avoids the potential safety hazards caused by the door swinging at will.
Silent buffer design
The silent buffer design of Half Moon Magnetic Door Stop is a highlight. The rubber buffer pad is not simply pasted, but is designed with a precisely calculated thickness and elasticity. Through the detection of professional impact testing equipment, when the door hits the door stopper at a normal speed, the rubber pad can instantly absorb more than 80% of the impact energy and reduce the collision noise to below 30 decibels. The noise level below 30 decibels is equivalent to the sound of a person breathing in a quiet room, which can almost achieve a silent effect. In contrast, the collision noise of traditional door stoppers without buffer design is usually around 50-60 decibels. The silent effect of this door stopper is equivalent to reducing the noise by about 25 decibels, creating a quiet and comfortable indoor environment for users.
Easy to install
The door stopper is very easy to install. It has 4 pre-positioned mounting holes on the back, with evenly distributed holes and a spacing of 30 mm × 30 mm. This design ensures the accuracy and stability of the installation. In the actual installation process, you only need to use an electric drill to drill a hole with a diameter of 4 mm and a depth of 25 mm on the wall, insert the plastic expansion tube, and then screw in the matching screws. The entire installation process does not exceed 10 minutes. Moreover, even users without professional installation experience can easily complete the installation according to the instructions. The installed door stopper is firm and stable, and can withstand the tension generated by frequent opening and closing of the door. After testing, after opening and closing the door 10,000 times continuously, the door stopper can still be firmly fixed on the wall without loosening or falling off.
Precise fit
Half Moon Magnetic Door Stop is suitable for common interior doors with a thickness of 35-45 mm. This fit range is determined by research and actual testing of a large number of door types on the market. After actual measurement and calculation, its semicircular arc fits the door edge at a rate of more than 95%. Whether it is a solid wood door, a composite door or a painted door, whether it is a smooth modern style door or a classical style door with carvings, the door stopper can fit tightly to ensure the magnetic attraction effect and buffering function. For example, when the solid wood composite door with a door thickness of 40 mm was tested, the gap between the door stopper and the door edge was only 0.5 mm, which was almost negligible, thus achieving perfect magnetic attraction and buffering effects.
Quality reliability
Half Moon Magnetic Door Stop has undergone rigorous quality testing and has reliable quality assurance. In the magnetic attraction and release cycle test, after more than 100,000 tests, there was no obvious attenuation of various performance indicators. After 1000 hours of continuous use at a temperature of -20℃ to 60℃, the material has no deformation, the magnetic force has not been significantly weakened, and the rubber has no aging and cracking. These test data are obtained through professional testing equipment and strict testing procedures. For example, in the magnetic attraction and release cycle test, automated testing equipment is used to simulate the frequent opening and closing actions of the door. After each test cycle, key indicators such as magnetic force and buffering effect are accurately measured to ensure that the product can still maintain good performance after long-term use. This makes its service life 3-5 years longer than that of ordinary door stoppers, providing users with long-term and stable use guarantees.

Daily cleaning
Regular cleaning of the surface of the Half Moon Magnetic Door Stop is key to maintaining its appearance and performance. It is recommended to wipe the surface of the door stopper with a soft dry cloth every week to remove stains such as dust and fingerprints. For Satin Stainless Steel surfaces, use a neutral detergent mixed with warm water in a ratio of 1:10, wet a soft cloth and gently wipe it, then wipe it dry with a dry cloth. This cleaning method can effectively remove stains on the surface of the door stopper while preventing the surface from being corroded by detergent residue. After actual testing, the surface gloss of the door stopper cleaned in this way can be maintained at more than 95% of the initial state, and there will be no scratches or discoloration caused by improper cleaning. During the cleaning process, avoid using rough cleaning tools or strong acid and alkaline cleaners to avoid damaging the surface treatment layer of the door stopper. Long-term adherence to the correct cleaning method can extend the service life of the door stopper and keep it as new.
Magnetic force detection and maintenance
In order to ensure the normal use of the Half Moon Magnetic Door Stop, it is necessary to conduct a simple test of the magnetism once a month. The door stopper can be adsorbed on a standard test iron plate of known weight, and the pulling force can be gradually increased using professional tensile testing equipment, and the suction and removal force can be recorded. If the magnetic force is found to drop by more than 10%, it may be that the magnet is aged due to external impact or long-term use. At this time, it is necessary to contact the manufacturer in time to repair or replace the magnet parts. In actual operation, a hotel found that the magnetic force of some door stoppers dropped by about 8% through magnetic force detection after using the door stopper for one year. After timely replacement of the magnet, the magnetic force recovered to 98% of the initial state. This shows that regular magnetic force detection can effectively prevent problems such as the door being unable to dock normally due to insufficient magnetic force, avoid safety accidents, and ensure the stable operation of the door stopper.
Buffer rubber pad maintenance
The rubber buffer pad is an important component for the Half Moon Magnetic Door Stop to achieve the silent buffer function. The wear of the rubber buffer pad should be carefully checked every quarter. If scratches with a depth of more than 1 mm or a wear area of more than 20% are found on the rubber surface, the buffer rubber pad needs to be replaced in time. When replacing, a rubber pad of the same material and thickness as the original should be selected to ensure that the buffering effect and silent performance are not affected. When using special rubber glue to stick, the surface of the door stopper and the rubber pad must be cleaned first, and then put into use after drying for 24 hours. During regular inspections, it was found that the rubber pads of some door stoppers were seriously worn. After timely replacement, the collision noise of the door was reduced by about 20 decibels, effectively improving the quietness of the office environment. Therefore, regular inspection and replacement of the buffer rubber pads are essential to maintain the quiet performance of the door stop.
Screw tightening inspection
The tightness of the installation screws of the Half Moon Magnetic Door Stop should be checked once every six months. If the screws are found to be loose, tighten them with a matching wrench to a torque of 1.5 - 2 Nm. This torque range is calculated accurately to ensure the tightness of the screws without damaging the screws or the wall due to over-tightening. For rusty screws, the rust should be cleaned with a wire brush first, then anti-rust grease should be applied and reinstalled. During regular inspections of classroom door stoppers, a school found that some screws were loose due to long-term use. After tightening them in time, the stability of the door stop was restored. If the loose screw problem is not dealt with in time, it may cause the door stopper to shift, affecting the adsorption accuracy and stability, and then causing problems such as the door cannot be closed normally or the magnetic force is weakened, which brings inconvenience to daily use.
Environmental adaptability maintenance
During the period of season change and large changes in temperature and humidity, special attention should be paid to the use environment of Half Moon Magnetic Door Stop. The humidity around the door stopper should be controlled at 30% - 70% as much as possible, and the temperature should be kept at 5 - 40℃. You can use a dehumidifier or humidifier to adjust the indoor humidity, and use air conditioning or heating to adjust the temperature. For example, in the rainy season, a family used a dehumidifier to control the indoor humidity at about 60%, effectively preventing the door stopper rubber pad from swelling and deforming due to excessive humidity, and avoiding the phenomenon of magnetic force weakening due to humid environment. When heating in winter, control the indoor temperature not to exceed 25℃ to prevent metal parts from aging rapidly due to excessive temperature. Through reasonable environmental adjustment, it can ensure that the door stopper can operate stably in different seasons and extend its service life.
Professional maintenance consultation
When you encounter a fault that cannot be solved by yourself, such as abnormal heating of the magnet, abnormal noise inside the door stopper, etc., you should contact a professional maintenance personnel in time. When contacting for maintenance, you need to provide detailed information such as the product model, purchase date, and fault phenomenon. For example, the door stopper of a commercial store had a phenomenon of heating the magnet and weakening the adsorption force. The store staff recorded the time and frequency of the fault in detail, as well as other accompanying symptoms, and provided this information to the manufacturer. Based on this information, the manufacturer quickly and accurately determined that it might be a fault in the internal magnetic circuit, and sent professional maintenance personnel with appropriate maintenance tools and accessories to provide door-to-door service, solving the problem in a timely manner. Disassembling the door stopper by yourself may cause product damage and loss of warranty service. Therefore, when encountering complex faults, seeking professional maintenance is the best choice to ensure that the door stopper returns to normal use.
