Seen in our life all kinds of glass bottles, because glass is widely used in our life, the glass is a kind of healthy packing materials, but also the shape of the bottle can be set into various shapes, actually exists between the thermal conductivity and the molding of glass bottles, today we introduce glass bottle manufacturers for thermal conductivity will which influence on forming glass bottles?
The thermal conductivity of the
glass larger influence on the cooling speed in the process of glass forming. The greater the thermal conductivity of glass, glass cooling the faster, the faster the speed of the forming and. In actual production, the thermal conductivity of the Ming glass material is greater than the thermal conductivity of deep color glass, therefore, for the art of artificial forming the eco-friendly tube requires heat conduction speed slower, glass products for mechanical forming requires that its heat transfer speed is faster. Artificial forming, blowing the operation of the technician to properly grasp the forming operation speed according to the truth, especially complex shape glass products and deep color glass.
glass during forming expansion or thermal contraction, with signs of thermal expansion coefficient of glass. With the generation of stress in the glass and glass size tolerance. After forming into the mold, and mold wall surface contact occurs due to cooling contraction, on the cold spots on the glass surface shrinkage, the biggest to the thickness of the internal shrinkage decreases. In this way, the glass surface is tensile stress. When the glass is still in the liquid state, due to the particle flow, quickly eliminate stress, partly to elastic solid state, but when the glass model for thermal expansion at the same time, the shrinkage of the eco-friendly tube and cast iron expansion, about 1% of the model 2% difference, thus in forming on the glass of the residual stress, easy to cause the surface crack is generated. Therefore should be considered in forming defects do not produce stress relieving speed problem. To this point in the actual production is also often in the mold to the glass cracking was found, sometimes after the mold is sent before the annealing furnace.
Guangzhou Lisson Plastic Co.,Ltd highlighted the need to foster a human openness to technological innovation.
Our vision serves as the framework for our lotion tubes wholesale and guides every aspect of our business by describing what we need to accomplish in order to continue achieving sustainable, quality growth.
While manufacturing cosmetic packaging manufacturers, we always pay attention to the technology and quality of the product.
The first machine to produce aluminium cosmetic tubes, the cheap cosmetic packaging cosmetic containers wholesale was invented in cosmetic containers for sale in where to buy cosmetic containers by cosmetic tubes suppliers and was subsequently improved.
