In the 1990s, the rapid heating of the electronics manufacturing industry became the darling of this era. In order to reduce product loss and end the embarrassing situation between employees and the company, large electronics companies successively adopted metal detection security doors and hand-held metal detectors as management. Employee behavior, reducing the loss of product edge. So the Metal Detector has its new role - product security. After the 9.11 incident, counter-terrorism became an important issue for the international community. The bombings and terror campaigns have made terrorists the targets that countries’ security agencies have vowed to crack down on. At this time, the international community's awareness of 'security precautions' was also mentioned to a new height. Affected by the 9.11 incident, the deployment of security work strengthened by all walks of life was affected by this, and the application fields of metal detectors also successfully penetrated into other industries.

The metal detection security door was born in 1960. In the industrial era, the first metal detectors were also mainly used in industrial and mining industries. They are effective tools for checking the purity of minerals and improving their efficiency. With the development of society, criminal cases have risen. In 1970, the metal detector was introduced into a new application field - security inspection, which is the prototype of the metal detection security door that we use today. Its appearance means that human awareness of security has entered a new era.

The emergence of a product has led to the development of an industry, and security inspection, which is both strange and familiar, has begun to enter the market. More than 50 years have passed, metal detectors have undergone several generations of detection technology changes, from the initial signal simulation technology to continuous wave technology to the digital pulse technology used today, the simple principle of magnetic field cutting of metal detectors was introduced into a variety of science and technology Achievements. Whether it is sensitivity, resolution, detection accuracy or work performance has a qualitative leap. The application area has also extended to many industries with the improvement of product quality.

In the 1970s, with the rapid development of the aviation industry, the occurrence of hijackings and dangerous incidents have gradually increased the importance of aviation and airport security. Therefore, metal detecting and security doors in many airport facilities play an important role in the investigation of prohibited items. Also in the 1970s, due to the emergence of metal detection security gates in airport security inspections, metal detection security gates were required to be used in large-scale games (such as the Olympic Games, Asian Games, National Games) exhibitions and the security of important government departments. Less security inspection equipment.

Since the 1980s, prison violence has been on a linear upward trend. How to effectively prevent and prevent violence as early as possible has become a top priority in prison management. While relying on police officers to strengthen management of prisoners, metal detection security doors are again It has become a must-have security inspection device for prison management agencies in the United States, Britain, Belgium, and other developed countries, forming an average of one metal per 300 prisoners.

Detection security doors are used for security inspections; at the same time, hand-held and portable metal detectors have achieved considerable development.
