As early as the initial stage of the high-speed rail industry, Mingdun Glass was given a heavy responsibility. As a research unit for the front windshield and window glass of high-speed EMU designated by the former Ministry of Railways, Mingdun's R&D team is racing against time and wrestling with difficult problems. From the extreme cold of minus 40℃ to the exposure above 70℃ on the surface, from the impact of bird impact at 380 km/h to the long-term erosion of sand and gravel, every harsh index is a technical battle that must be won. Mingdun has successfully broken through a series of core technical barriers, such as high strength, high toughness, high light transmission, light weight and electric heating defrosting and defogging. Its products not only meet the extreme requirements of high-speed trains for safety, but also reach the international advanced level in terms of comfort indicators such as sound insulation, heat insulation and ultraviolet resistance.
Crossing the track: the core technology empowers multiple fields
Deeply cultivating the deep "internal strength" accumulated by rail transit safety for decades has given Mingdun Glass the confidence and strength to expand into a wider field. The company is keen to successfully transfer the cutting-edge technology of special glass to two key areas: public safety and green energy.
In the field of public safety, Ming shield glass has built a series of "invisible solid defense lines". For banks, prisons, embassies and other places with extreme safety requirements, bulletproof glass and bulletproof shielding glass developed by Mingdun caneffectively resist the impact of gun shooting and violence; Its high-performance fireproof glass has won valuable time for personnel evacuation and property protection. These products integrate safety and architectural aesthetics, silently guarding social peace.
At the same time, Mingdun Glass actively responded to the national new energy strategy and turned its attention to green travel and clean energy. On the premise of ensuring safety, the company has further optimized the lightweight design of the front windshield and side window glass developed for new energy bus vehicles, helping the vehicles to improve their cruising range. In the field of solar facilities, the special glass module provided by Mingdun has high light transmittance, high strength and excellent weather resistance, which significantly improves the efficiency and long-term reliability of photovoltaic power generation system.
From following to leading, from singleness to pluralism, the development track of Mingdun Glass is a vivid epitome of independent innovation and continuous breakthrough of high-end manufacturing industry in China. Nowadays, Ming-dun glass is silently supporting the speed, safety and sustainable development of the country with its solid and transparent "guardian", whether on the speeding train, in important security places or in the green energy matrix.

In addition to the excellent air pressure self-balancing function, this innovative product of Ming dun also integrates an efficient electric heating system, which constitutes a double protection system for the window of plateau trains. The electric heating device is integrated into the metal frame of the air pressure balance system in a plug-in way, and is connected with the train power supply system through external wires. Its role is crucial. In the cold and humid environment on the plateau, even if the air pressure is balanced, water vapor condensation may still occur in the glass hollow layer due to temperature difference or trace air exchange, which may lead to fogging or frosting of the glass and affect the visual field. The integrated electric heating device can be started as required to gently heat and disperse the moisture entering the glass or existing on the surface of the cavity, so as to ensure the drying of air in the hollow layer and the lasting permeability of the windo
The technical core of self-balanced electric heating insulating glass of Ming dun is embodied in its precision-designed integrated system of molecular sieve and metal frame. The system is not a simple opening, but a complex and reliable functional module. On the inside of the glass, a circle of molecular sieve device is firmly combined with the edge of the glass through high-performance sealant to ensure the reliability of sealing. The metal frame it carries is the essence of the design: the "glass inlet" on the inner side accurately aligns with the hollow layer and is the sensing and adjusting port of the internal air pressure; The "air inlet" on the outside faces the cabin environment and is a channel for introducing external pressure. They are communicated through the internal cavity of the frame, forming a closed-loop pressure exchange path. It is this seemingly small but vital structure that realizes the air matriculation and pressure balance between the interior of the insulating
The air in plateau area is thin, and the air pressure is significantly lower than that in plain area. The window of ordinary train may become a potential danger source due to the pressure difference between inside and outside during operation. The self-balancing electrically heated insulating glass newly developed by Ming dun Company is born to cope with this harsh environment. Its revolutionary design is to make the insulating glass have the ability of "spontaneous breathing and dynamic balance". The controllable conduction between the hollow layer inside the glass and the external environment is realized through the molecular sieve device bonded to the inside of the glass and its special structure frame. When the altitude of the train rises, the external air pressure decreases, and the relatively high air pressure in the glass cavity can "exhale" some air through this channel; On the contrary, when the altitude decreases, it can "inhale" air, and always maintain the dynamic balance o
With the rapid development of rail transit today, the technical challenges brought by the special environment of the plateau can not be ignored. Ming dun Company has successfully developed a breakthrough "self-balanced electrically heated insulating glass" for the potential safety hazard of train windows caused by the drastic change of plateau air pressure, which provides an innovative technical path to solve the pain points in this industry. This product skillfully integrates a circle of molecular sieve device around the inner side of traditional insulating glass, which is firmly bonded to the glass substrate through external sealant. Its core lies in the specially designed metal frame: the inside is provided with a "glass inlet" communicating with the glass hollow layer, and the outside is provided with an "air inlet" communicating with the external environment, thus constructing a controllable and stable air pressure balance channel between the glass cavity and the external atmosphe
