In 2025, AMAN supplied a 3-station injection blow molding (IBM) machine to a pharmaceutical-packaging manufacturer in Bangladesh, for 10–30 ml HDPE and PP eye-drop, dropper and medicine bottles.
Small pharma bottles leave no room for error: the neck and thread must seal repeatably down to fractions of a millimetre, and on containers this small any flash is a visible defect. That is why the process here is IBM, not extrusion: the preform is injection-moulded onto a core rod — so the neck and thread are formed by injection to tight tolerance — then blown to final shape and stripped at the eject station. No pinch-off means no weld seam and no flash to trim.
AMAN set up the 3-station cycle for the 10–30 ml range and validated neck dimensions and bottle consistency on production-representative HDPE/PP before shipment. The machine was installed and commissioned on site, then handed over with operator training and after-sales support.
