What’s the pressed glass processing?
Pressed glass is a form of glass made by pressing molten glass into a mould using a plunger. The molten glass is placed into the mould and then pressed onto the base mould using a machine with a plunger to form the initial shape.
How to press the glass?
The molten glass is placed into the mould and then pressed onto the base mould using a machine with a plunger to form the initial shape.
It is then removed from the mould and placed in an annealing furnace to remove internal stresses and ensure safety, followed by post-processing such as edge grinding, beveling, sandblasting, painting, coating etc. …. Depending on the product and the customer’s requirements, these post-processing operations are followed by toughening if necessary.
How many sets of molds are required for the pressed glass process?
It is worth noting that at least 6 sets of moulds are needed to process a large order, as the temperature of the molten glass after pressing is very high and it is not easy to release it from the mould at this point. So it takes a little time to cool down and a little time to fully shape it and then allow it to be released from the mould, but at the same time, the line cannot be stopped so more grinders are needed to keep it running intact, which is why at least 6 sets of grinders are needed. When the last pressing is completed, the glass is ready to be taken out of the first glass from mold. This is a cycle that increases production efficiency and ensures that the glass is fully formed.
Where pressed glass is used？
Glass products are 100% recyclable, high temperature resistant and impact resistant, so they are used in a wide range of applications such as car lights, stage lights, garden lights, landscape lights, boat lights and explosion-proof lights.
