The Benefits of Vacuum in Bottle Production

Depending on the applied IS technology, vacuum can be relevant or absent. Many hollow glass plants world-wide still run without the support of vacuum, as additional form of energy to improve the moulding process. Still, starting from a certain complexity of the glass container like for higher ‘esthetical´ quality standards as required for high end perfume bottles, sophisticated engravings or for changing wall thickness, vacuum does strongly influence the moulding process. Besides reduced rejection rate, also moulding speed is improved. Different vacuum pump solutions and practical examples will be explained by Pneumofore, the world-wide leader of vacuum systems for glass works.

The example of the Gerresheimer factory in Mumenmier, Belgium states productivity increase of 6 % since the implementation of vacuum on their is machines. Provided vacuum is present, Pneumofore does engineer a dedicated
solution for the long-term, durable and efficient design of the vacuum system. The frequent mistake of considering purchasing price only without analysis of additional costs can generate unpleasant surprises down the way.
