When you manufacture a glass container you must use a myriad of mould equipment. Where these articles unite, seams occur within the container. If the seam fails to meet the specified standards, manufacturers will reject the container. Therefore, it's vital that you examine your mould gear. This is the only way to reduce the likelihood of seams

Neckring parting line

Firstly, you need to look at the neck ring parting line and the blank mould. Where these two join together, there is a seam. This is known as the blank seam. It is essential that this is strong and without flaw.

Blank moulds come in two parts. When you use them they start by closing around the neck ring. Afterwards, they accept the hot gob of glass. Where the two segments of the blank mould connect, there's a seam. It could manifest on the container as a wavy line.


The baffle is also important here. It lies on top of the blank during counterblow. This is the point where the parison forms. There can be a terrible match between the baffle and blank mould. If there is, it's possible to find a seam or baffle mark on the bottom of the container.

At Penico Gauges we have the honour to distribute our blank mould gauges and other products to locations all over the world. More than 40 countries have found a use for the merchandise. This just shows how good we are at making these tools.
