The difference between regulated and molded bottles

- Jul 09, 2018-

1. The method is different. The control bottle is firstly drawn into a glass tube, and then the bottle is made into a bottle in a vertical rotary machine using a glass tube. The molded bottle is made into a bottle by using borax or quartz sand in a kiln row machine. The control bottle does not use the mold, only two sets of mold wheels are used, and the mold bottle needs a complete set of molds;

2. The appearance is different. The appearance of the control bottle looks brighter, the transparency is better, and the molded bottle is rougher.

3. Material: The control bottle is generally low borosilicate in the country. It can also make high borosilicate and medium borosilicate. The molded bottle is soda lime glass, because the material is inferior to the control bottle in the acid resistance. Control bottles are better lyophilized, while molded bottles cannot be lyophilized.
