Production Process Succeeds in Both Glass Strength and Heat Resistance

If strength had been the only problem, simply increasing the thickness of the glass could resolve the problem of implosion. But there was also the matter of heat generated. It is scientific fact that thinner glass endures better when hot water is poured over it than thick glass. During the production process, CRT monitors are exposed to a wide range of temperatures from room temperature to 450°C. Thick glass is most dangerous when there is such a varied change in temperature. Should the CRT implode during production due to this factor, tremendous damage would result. This is where Mitsubishi Electric's precise computerized simulation technology was of importancet to correct any hazards. It was used to devise a design and manufacturing process that made it possible to produce glass with a 14mm thickness instead of 28mm to reduce the chance of heat related implosions, while at the same time keeping it strong enough to resist pressures related implosions.
