Things Wine Bottle Factories Should Consider When Producing Glass Bottles

As glass bottles continue to gain popularity as a packaging material, demand for them is increasing, and so are quality requirements. This requires wine bottle factories to constantly monitor production conditions. So, what should wine bottle factories pay attention to when producing glass bottles? Below, we will briefly discuss the important considerations wine bottle factories should take into account when producing glass bottles.

Inspecting molds. Before producing glass bottles, wine bottle factories must first inspect the molds. Since wine bottle factories often develop new molds based on customer-provided molds or drawings or sample bottles, they must communicate and negotiate with customers during mold development to finalize key dimensions that affect the final molding process. This ensures that the glass bottles produced by the wine bottle factory meet customer approval.

Perform first article inspection. When producing glass bottles, wine bottle factories must randomly inspect the first few products after the molds are loaded onto the machine and before they enter the annealing line. They focus on the mouth height, inner and outer diameters, correct and legible base engraving, and the correct bottle body design. After the bottles emerge from the annealing line, they undergo comprehensive inspections based on the drawings. Furthermore, they must also perform volume and weight measurements. If necessary, they can fill the bottles with water and physically assemble them with the customer-provided caps to verify proper fit and leaks. Furthermore, they must perform internal pressure, stress, and acid/alkalinity tests to ensure the bottles meet customer requirements.
