The glass sector is one of the industrial fields that provides input to many sectors such as automotive, construction, white goods, food, beverage, pharmaceutical, cosmetics and tourism with its products and has a very important position for our national economy with the employment, production and export it provides. Energy use is also intense in the glass industry, which requires high fixed capital investment. Economies of scale create the necessity of working with high capacity. The fact that glass production is based on smelting (melting) technology requires that glass furnaces are constantly in operation and production is uninterrupted. This need for uninterrupted production makes the glass industry a sensitive sector that needs to be observed. The stages of glass production are as follows;
First, the blend is prepared by mixing the natural raw materials with the help of mixers. The prepared blend is sent to the furnaces to be melted.
Mixture and Glass Crumb mixture is raised up to 1550°C and melted in furnaces using D.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)
Molten glass from the furnace; The glass is given its final shape by using one of the BB (Blow-Blow), PB (Press-Blow), NNPB (Narrow Neck Press-Blow) techniques in molds previously produced according to the bottle shape. The glass packaging coming out of the molds is transferred to the Annealing Furnace passing through the Hot Coating Unit at 600°C.
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 stresses 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 process).
Am 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.
We have three stages of control.
1- Glass packages to which cold coating liquid has been applied 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 detection machines, final visual checks are made by both the online machines and the 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 shaping area. At the same time, faulty glass packages are discarded and recycled in order to feed them back into the furnace.
Glass packaging products approved by the Quality Control are packed by packaging machines without human touch and delivered to the warehouse with the help of conveyors, ready for shipment.
Glass packaging products from production are protected and transported in our specially designed warehouses for safe delivery to our customers.
