“Glass is alive”, this is the conception and perception of every glass craftsman. In the series of “Glass life”. Let us start from glass forming in this part.
Glass forming is a process that transforms molten state glass into fixed geometry state. This process is the result of complex combination of many different properties actions, among them, mechanical and thermal actions are most significant. The process of forming can be divided into two stages, i.e. modeling stage and shaping stage. Modeling stage defines the shape, shaping stage solidifies it. These two stages both are related to the glass viscosity, because molten glass can have any desired viscosity, the glass material has different forming methods. It can be divided into the following types roughly:
Pressing method: inject molten glass into a given model, place die ring, press the plunger chip, then form products .
Blowing method: blow molten glass in a model through blowing tube or blowing head. This method is divided into manual blowing and mechanical blowing.
Pulling method: blow molten glass in a model through blowing tube or in mechanical equipment, cooling, then pull according to the requirements.
Calendering method: calender molten glass into forming products through rollers or roller plates.
Casting method: inject molten glass into a mold to forming products after annealing and cooling.
Float forming: this is a special method to form flat glass, molten glass flows into a tin tank, and a flat can be formed on the surface of molten tin
The main glass forming techniques are as follows:
we can blow spherical, circular, square, six-prism glass shell products according to the customer’s requirements
