Colored glass tubing is very common in the industry and in our lives, and it is the most cost-effective product, and many people enjoy the convenience that colored glass tubing provides. But are you familiar with the process of colored glass tubing?

After the batching material is fed into the feeding opening of the furnace by a feeding machine, it is melted in the furnace. The whole furnace is divided into two parts: a melting pool and a clarifying pool. The middle part is separated by a bridge wall with a flow hole. The batch is first melted in a melting tank. The bottom of the melting tank is provided with a discharge hole to allow the dirty material and the striped glass liquid deposited at the bottom of the tank to flow out. After the clarification, the glass liquid flows into the channel. The function of the channel is to adjust the glass liquid temperature to the dropping temperature needed for the molding to ensure the glass viscosity during the molding.

Glass molding from the use of production tools to be divided into manual, semi-mechanical, and mechanized methods of three categories. In these three categories, the production method can be divided into blowing method, drawing method, pressing method, and blowing-pressing method four categories.The colored glass tubingis then annealed to reduce the thermal stress created during the molding process. The glass is heated in an annealing furnace to a temperature slightly above the strain point and cooled at a rate until room temperature. The temperature distribution of each point in the annealing furnace is set according to the technological requirements. The inlet temperature is higher, then gradually increases, and then slowly decreases until the allowable temperature is reached.
