As a professional manufacturer & factory from China, Shilong Machinery supplies semi-automatic piston paste filling machines. This pneumatic piston metering type is widely adopted in the market. Driven by an air cylinder, the piston works together with a one-way rotary valve (3-way valve) to complete two cycles: material suction and discharging. Operators place containers manually, and a foot switch serves as the trigger signal to finish one-time quantitative filling.

Suitable for spout stand-up pouches filled with fluid and semi-fluid materials (sauce, laundry detergent, fruit juice, honey, paste, etc.). Compared with semi-automatic filling and manual filling, its advantages are analyzed from production, quality, operation & maintenance and cost dimensions.

Applicable: Flowmeter-type / Piston-type automatic liquid filling machines, for inaccurate filling caused by wrong filling parameters.

Seals on dual-head filling machines are mainly installed on filling pistons, valve seats and material cylinder inlets/outlets. They are reciprocating dynamic seals. Their core differences lie in five aspects: media resistance, temperature resistance, wear resistance, food compliance and cost.
