<p>A method of manufacturing a TV product of glass, such as a TV screen or a TV cone, in which method a blob of a viscous glass is introduced at a high temperature into a mould, whereafter a plunger is pressed with a required pressure into the viscous glass to obtain the desired shape of the product, after which the product is cooled to room temperature. In the manufacture, the plunger remains in contact with the product until the product is dimensionally stable, which is obtained by choosing the ratio between the time period during which the plunger is in contact with the product and the time period during which the product remains in the mould to be greater than 0.5 and smaller than 1.</p> |
