The role of glass wall thickness in production

There are a lot of glass bottle production enterprises in order to reduce the production cost, reduce the wall thickness of gram to cut glass bottles, however, by reducing the container weight to increase revenue is not an easy thing to do. Not blindly relieve container weight. Many lightweight project the reason for failure is no preparation before put into production or to inadequate preparation. To ensure the lightweight the success of the project, be sure to follow the right steps and methods of

l first and most important, must carry on the design and analysis. The advantage is:
1) The bottle is simulated and analyzed the critical stress points
2) Modify the bottle shape make the internal pressure, vertical pressure and impact load stress caused by minimizing the
3) Set thickness of glass bottles of vertical distribution patterns, determine the key measure to eliminate and control position and set up the products
4) limit Before to make new mould and put into production the new design can be repeated experiment
l second, to make new mould or modify the original mold to fully implement the new bottle design
in the process of production, the outer surface of the mold can control the bottle and ensure the uniform appearance of the bottle. But on the inner surface of the bottle, there is no way to control. In the past, in the production of heavy bottles, wall thickness is not need to pay attention to. But as the bottle weight, optimize the distribution of glass material becomes crucial. Monitoring material distribution of the glass container, therefore, set containers ideal thickness of base line and the key points are the thickness control becomes very important. Third,
l in the process of production, must be the container wall thickness monitoring. This is because the more strict to the requirement of production process. The bottom of the bottle - the root - - This area is very critical for pressure vessel performance. Due to internal pressure stress concentration in this area, in the event of a collision damage easily, so must keep enough wall thickness in this area. In this part, glass material plays a limited role, can reduce the inflation caused by internal pressure stress effect. The bottle - standing wave area - - This area is from the bottle clamping and collision Angle is very important. In using blow molding of the most obvious on the bottle, because standing wave is a remarkable characteristics, and there is no way to avoid it. We hope that this area of the glass but the thinnest thickness reaches a certain minimum requirements necessary to maintain enough of impact strength. The contact point & ndash; These also affect the bottle clamping and impact the performance of the key areas. Unless there is enough wall thickness under impact load, or collision stress will make the container damage.


thickness measurement and monitoring instrument is on the wall thickness distribution in the production management and control must be carried out on the wall thickness measurement. In front of the wall thickness measurement system developed online, this is both time-consuming and glass made by artificial sampling and wall thickness measurements. This situation limits the development of lightweight. In the AGR online thickness measurement system ( OLT） Available after 100% online thickness measurement and the bottle wall thickness distribution of active management possible. So you can in maintaining the bottle design performance under the premise of further reduce redundant material to effectively reduce the weight of the bottle.
