New technologies

Equipment and technology of high-temperature isothermal molding of products from glass and glass ceramics

The technology is based on the use of the unconventional moulding equipment - HEAT EXCHANGER with LIQUID-METAL heat-transfer agent which works on the principle of evaporation-condensation systems. The moulding equipment provides:

• adequate thermal conductivity of the moulding components
• isothermal distribution of temperatures over their surfaces which does not depend on the geometrical shape
• intense controlled abstraction of heat from the moulding surfaces

New approaches can be used in press moulds, moulds for centrifugal moulding and sagging, blowing moulds and other equipment.

THIS TECHNOLOGY AND EQUIPMENT were used at ORPE "Technologiya" for the automated production of kitchen utensils from heat resistant glass, thin panels for household electric stoves. The technology and equipment HAVE UNDERGONE TESTS in the production lines of a number of Russian and foreign firms. They were used in the manufacture of car and aircraft head lamp glasses, explosion-safe protective caps, kitchen utensils from PYREX glass.

ADVANTAGES:

• total absence of waviness on the surfaces of moulded articles and hence the improvement of lighting and aesthetic parameters
• reduction in the article wall thickness and hence a 15-30% reduction in the article weight
• increase of the equipment service life by a factor of 1.5-2 as compared to the conventional equipment
• possibility of abandonment of costly metals and alloys which are used in conventional moulding equipment
• increase in production line productivity

The development is protected by the International Patent Application PCT/RU 94/00132 and Czech Patent N285701.

METHODS OF PRODUCTION of WALLS AND COVERS FOR THE ELECTRIC GRILLS

METHODS OF PRODUCTION of WALLS AND COVERS FOR THE ELECTRIC GRILLS from thermally polished glass based on free sagging on a travelling oven of the whirligig type and forced sagging in a batch furnace of the cap type with the supply of vacuum into the mold. The process of cover holing is combined with the process of sagging at the expense of preliminary machining and chemical treatment of blanks.
