Frequently Asked Questions
Q1: What products can this piston filling capping line handle?
A1: The line is built for viscous liquids and pastes—soy sauce, dish detergent, ketchup, oyster sauce, chili sauce, jam, shampoo, and liquid soap. The piston metering system handles viscosities from thin dressings to thick pastes without foaming or dripping. For products with large particles (chili flakes, herbs, fruit chunks), we use large-diameter filling nozzles to prevent clogging and ensure smooth product flow.
Q2: How customizable is the nozzle count and filling speed?
A2: The line is fully configurable: 2 to 12 filling heads depending on your target throughput, with speeds from 600 to 3,500 bottles per hour. Tank capacity starts at 200L and scales up. We design the exact layout—number of heads, conveyor length, capping station type—based on your bottle size, fill volume, and daily production target.
Q3: Can the filling and capping modules work independently or only as one line?
A3: Both. The line operates as an integrated filling + capping system with shared conveyor and synchronized PLC control. But each module (filler, capper) can also run standalone or integrate with existing equipment in your factory. The conveyor speed and timing are independently adjustable per station.
