Semi-automatic filling machine, as the name suggests, is a semi-automatic type of filling machine. Unlike fully automatic filling machines, the main function of a semi-automatic filling machine is filling, with fewer additional functions. It does not come with auxiliary equipment such as conveyors, cap sorters, capping machines, coding machines, case packers, or case sealers like fully automatic filling machines do.

Semi-automatic filling machines also come in many classifications. Based on the filling principle, they can be divided into volumetric metering type, mass metering type, and volumetric-mass type. According to the number of filling heads, they can be categorized as single-head, double-head, or multi-head. They are widely used for quantitative liquid packaging and filling in industries such as edible oil, lubricating oil, wineries, chemical, and paint.

Semi-automatic filling machines adopt new microelectronic technology and advanced liquid flow metering control technology, integrating mechanical, electrical, pneumatic, and liquid flow metering technologies, as well as computer communication control technology. They feature a simple structure, stable performance, easy operation, convenient installation and debugging, high metering accuracy, and strong anti-interference capability. They are widely used for quantitative liquid packaging and filling in industries such as edible oil, lubricating oil, wineries, chemical, and paint.

Semi-automatic filling machines employ a unique real-time temperature tracking technology that tracks the temperature of the measured medium over a wide range, achieving real-time compensation for medium density. This completely avoids the impact of medium temperature changes on filling accuracy, ensuring high-precision automatic liquid filling. This is different from filling (packaging) equipment produced by other domestic manufacturers, which use volumetric metering methods, mostly selecting piston or rotary displacement flow meters. Their metering methods are outdated, with low metering accuracy, and they fundamentally cannot address the issue of the volume of the filled liquid changing with temperature, far from meeting the requirements of high-precision quantitative filling.
