Glass Making

1
Blend
Glass Packaging is produced from the use of natural raw materials.
% 65 Silica Sand
% 22 Soda
% 14 Dolomite
% 10 Limestone
% 8 Feldspar
% 1 Other auxiliary raw materials
Glass cullet
The blend is prepared by mixing the natural raw materials in the above-mentioned proportions with the help of mixers. The prepared blend is sent to the furnaces to be melted.

Furnace
Mixture and Glass Crumb mixture is raised up to 1550°C and melted in furnaces using natural gas and electricity, which consists of refractory structures, and the melted glass is cooled under control and sent to the Forming Machines at around 1200°C.

Shaping (NNPB process)
The molten glass coming from the furnace is given its final shape by using one of the BB (Blow-Blow), PB (Press-Blow), NNPB (Narrow Neck Pres-Blow) techniques in molds previously produced according to the bottle shape. Glass packaging coming out of the molds is transferred to the Annealing Furnace passing through the Hot Coating unit at 600°C.

Hot plating and Annealing Furnace

Hot coating process is applied to glass packages immediately after forming machines. The purpose of this process is to close the micro cracks in the bottles and to create a primer for the Cold Coating process that will be applied after the annealing furnace.

During forming, glass packages are loaded with undesirable tensions that reduce their strength as they cool suddenly and uncontrollably. Annealing furnaces are used in order to eliminate the resulting stresses (tension) by controlled cooling (annealing).

Cold Coating
Glass packages can be scratched by touching each other as they move along the lines. These scratches can have a negative effect on strength. In order to prevent these scratches, a water-based food-grade cold coating liquid is applied to the contact areas on the outer surface of the glass packages, which provides slipperiness.

Controls
We have three stages of control.

1- Glass packages with cold coating liquid are subjected to various controls and tests by sampling method (visual control, gauge control, pressure and impact control).

2- All of the products coming from the forming are passed through the latest technology defect separation machines for head, bottom, side surface, crack, mouth sealing and narrow neck control.

3- Samples are taken from the products that pass through the defect sorting machines, final visual controls are made by both online machines and operators, and they are sent to the packaging after the approval of the quality department.

The error is corrected by instant notification of the found errors to the forming area. At the same time, faulty glass packages are discarded and recycled in order to feed them back into the furnace.

Packaging
Glass packaging products approved by the Quality Control are packaged by packaging machines without human touch and delivered to the warehouse with the help of conveyors, ready for shipment.

Storage
Glass packaging products from production are protected and transported in our specially designed warehouses for safe delivery to our customers.
