Ramsey Products Helps a Glass Manufacturing Company Eliminate Problems with Container Defects

A leading glass manufacturing company of jars for food products was challenged by their customers to produce higher quality, blemish free containers. Faced with this new challenge, the bottle manufacturing company contacted Ramsey for assistance.

A leading glass manufacturing company of jars for food products was challenged by their customers to produce higher quality, blemish free containers. Specifically the customer wanted to reduce the size and number of small cracks, also called checks, which appeared on the bottom of jars during bottle production. Faced with this new challenge, the bottle manufacturing company contacted Ramsey for assistance.

Working with glass manufacturing personnel, Ramsey’s technical sales team was able to identify the source of the glass checking. During container production, red hot jars move from the mold to a dead plate and then to a glass conveying chain. The containers are very fragile during this stage of production and it is critical that the glass be transferred smoothly from the dead plate to the chain. After examining the actual glass conveyor, it was determined that the transfer of jars to the chain was not occurring as smoothly as it should, and cracks were developing during the transfer process.

In order to provide for better product transfer, and fewer cracks, Ramsey proposed that the conveying chain be replaced with a different style of chain. The original chain was an extended pitch, link and spacer, chain design that contained large openings, or gaps, in the chain surface, as a means for increasing air flow. In this application, where smooth product transfer was especially important, Ramsey recommended a Ramsey Ultralife ½” pitch, all link, conveyor chain. The recommended chain contained much smaller gaps in the chain surface, and was expected to provide better glassware support during the transfer process.

After installation of the new Ramsey conveying chain, the glass manufacturing company experienced an immediate improvement in container quality. The incidence of checks and bottom defects was significantly reduced and according to the final customer, "…container quality was the highest they had seen from any source."
