Track every bottle design, parison setting and pallet back to its resin lot.

Hollow containers hide faults. Thin walls are the usual culprit. A bottle with a thin shoulder looks fine on the line and then splits in a filler’s warehouse, weeks after the shift that made it ended. The record that explains it, such as parison programme, resin lot or cooling time, is rarely near the pallet.

Management software for blow moulding companies keeps those settings with the production run, the test result and the delivery note, so one search opens the whole history of a pallet. Send us one bottle design and we will trace it from enquiry to pallet. The first search then shows where your trail goes cold.

A filler, a lubricant blender or a dairy sends a container specification giving nominal volume, neck finish, target weight and a drop or top-load requirement. You quote from container weight, cavities per mould, expected cycles per hour and the cost of HDPE or PET resin and colour masterbatch, with regrind share added to the sheet. A new mould means a design sign-off and a trial. Both are recorded.

On the floor, an extrusion blow machine or a stretch blow machine is set up for the mould. Flash is trimmed and fed to the grinder as regrind. Operators weigh bottles, check wall thickness with an ultrasonic gauge and run leak tests at set intervals through the shift. Bottles are counted into cartons or bagged onto pallets, with a layer count and a pallet label on each.
