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.

Mingdun fire retardant laminated bulletproof explosion-proof glass to deal with sudden fire hazards
Mingdun fire retardant laminated bulletproof explosion-proof glass to deal with sudden fire hazards In view of the industrial pain point of the closed space of rail transit carriages, which is caused by the rapid melting and fragmentation of ordinary glass in case of fire, the rapid spread of open flames and high-temperature smoke, Mingdun developed a special laminated bulletproof and explosion-proof glass with high temperature resistance and flame retardancy, which was pressed by a flame-retardant adhesive layer and high-strength fireproof glass. Key words: high temperature resistance, buffering and fire prevention, emergency protection, and rail transit fire prevention.
Mingdun heat insulation laminated bulletproof explosion-proof glass balanced carriage temperature control In view of the industry pain point of high-speed rail exposed to strong light during the day, heat poured into the car through the window, air conditioning load surged, ordinary laminated glass could not block infrared heat energy, and the sweltering energy consumption in the car increased, Mingdun was equipped with a heat insulation functional laminated film to create a special heat insulation laminated bulletproof explosion-proof glass for high-speed rail. The heat insulation special laminated layer blocks the infrared radiation of sunlight, reduces the heat penetration through the window, stabilizes the internal temperature of the carriage, and reduces the energy consumption of train air conditioning. Key words: temperature control, rubber clamping, energy saving, safety and heat insulation.
Mingdun silent laminated bulletproof explosion-proof glass to create a quiet ride space
Mingdun silent laminated bulletproof explosion-proof glass to create a quiet ride space In view of the wheel-rail noise, wind noise and tunnel echo caused by high-speed running of high-speed rail, the poor sound insulation effect of ordinary single-layer/ordinary laminated glass, the noise in the car affecting passengers' rest and drivers' concentration on driving, Mingdun developed a special laminated bulletproof and explosion-proof glass with damping and sound insulation, which was combined with a multi-layer protective substrate to form. Key words: sound insulation and noise reduction, cushioning and shock absorption, silent riding and explosion protection.
Special laminated bulletproof and explosion-proof glass for Mingdun high-speed railway to build a safety line for high-speed travel In view of the industrial pain points of the high-speed rail window, such as broken glass fragments scattered and scratched by the impact of gravel and birds, weak single-layer glass protection, and the whole piece falling off after impact, Mingdun deeply cultivated the core technology of composite laminated glass to create laminated bulletproof and explosion-proof glass for rail transit. The product adopts multiple high-strength glass substrates with high-toughness PVB explosion-proof interlayer, which is bonded and cured at high pressure and constant temperature, and the adhesive layer is closely attached to the glass without delamination and hollowing. Key words: multi-layer laminated rubber, fragment locking, integrated molding, rail crossing safety base.
