The diagram shows a method of shaping glass containers.
The diagram shows steps of making glass containers.
Overall, the major steps of shaping glasses, include setting the right temperatures and pressing the product after which, quality inception is done by specialist.
First off, the pieces of raw glass materials are heated in furnace in 105 degreesC. After, the heated material is pressed in mould to give shape to molten glass. The product then is pressed to another mould but to a thick-walled container. The process follows by leaving the glass to be cooled by the air.
One of the crucial stages involves heating in kiln, where maintaining the temperature 482 degrees is crucial for the next step. Once the product is heated enough, it anneals for 1 hour by 25 degrees. The last steps involve quality inspection. If glass does not have any defects or quality issues, it can be packed and ready for sell. In case if glass is broken or not suitable for use, it goes to waste.
