SGGZ-8 Two-Head Oral Liquid Filling & Capping Machine
Product Overview
Product Overview
The SGGZ-8 Two-Head Oral Liquid Filling & Capping Machine is a fully automatic oral liquid filling machine designed for filling and screw capping pharmaceutical liquids, healthcare products, nutraceuticals, and other low- to medium-viscosity formulations. Suitable for containers ranging from 20 ml to 500 ml, the machine combines precision liquid dosing with reliable cap tightening in a compact, production-ready solution.
Engineered with a 316L stainless steel piston filling system, PLC control, and a patented four-knife magnetic torque capping mechanism, this automatic bottle filling and capping machine delivers stable filling accuracy, consistent sealing quality, and dependable performance during continuous operation. The intelligent no-bottle-no-filling function helps minimize product waste, while the user-friendly touchscreen simplifies production adjustments for different bottle sizes and filling volumes.
Designed for pharmaceutical manufacturers seeking efficient, GMP-oriented packaging equipment, the SGGZ-8 can also be integrated with bottle unscramblers, washing machines, sterilization tunnels, inspection systems, labeling machines, and cartoning equipment to create a complete oral solution filling line.
How It Works
The production process begins with bottles entering the machine through an automatic infeed system, where they are accurately positioned for filling. Once detected by the sensors, the PLC activates the 316L stainless steel piston pump, delivering precise volumetric filling without dripping or product loss. If no bottle is detected, the machine automatically suspends filling to prevent unnecessary waste.
After filling, bottles are transferred to the capping station where caps are automatically fed and positioned. The patented four-knife magnetic torque mechanism applies consistent tightening force, producing secure, uniform screw caps while protecting bottles and closures from excessive torque. Finished products are then discharged for labeling, inspection, or downstream packaging, allowing the machine to operate seamlessly within a fully automated pharmaceutical packaging line.
Key Features
High-Precision Filling for Pharmaceutical Liquids
The filling system utilizes a precision 316L stainless steel piston pump, making it suitable for oral solutions, syrups, herbal extracts, vitamin liquids, and other pharmaceutical formulations. The hygienic wetted parts are easy to clean and designed to support GMP production environments. With a filling accuracy of ≤±2%, manufacturers can maintain consistent product quality while reducing liquid waste during continuous production.
Reliable Magnetic Torque Capping Technology
Unlike conventional screw capping systems, the SGGZ-8 adopts a patented four-knife magnetic torque design that delivers stable tightening force for both metal and plastic screw caps. The result is smooth sealing, attractive cap threads, and a capping success rate of 99% or higher, helping reduce packaging defects and improving production consistency.
Intelligent PLC Control for Easy Operation
The machine is equipped with an industrial PLC control system and an intuitive touchscreen interface, allowing operators to quickly adjust filling volumes, monitor production status, and modify operating parameters without complex mechanical adjustments. This intelligent control system shortens changeover time and improves production efficiency when different bottle specifications are processed.
Hygienic Design for GMP Manufacturing
Every product-contact component is manufactured from pharmaceutical-grade stainless steel to ensure excellent corrosion resistance and easy cleaning. The machine features a compact, enclosed structure that simplifies routine maintenance while supporting hygienic production practices commonly required by pharmaceutical and nutraceutical manufacturers.
Flexible Bottle Compatibility
Supporting bottle capacities from 20 ml to 500 ml, the machine accommodates glass bottles and compatible plastic containers fitted with metal or plastic threaded caps. This flexibility enables manufacturers to package multiple product formats on a single production platform while minimizing equipment investment.
Easy Integration into Complete Packaging Lines
The SGGZ-8 is designed as a standalone liquid filling machine or as part of a fully automated production line. It can be integrated with bottle unscramblers, bottle washing machines, tunnel sterilizers, visual inspection systems, labeling machines, inkjet printers, and cartoning machines, providing manufacturers with a scalable packaging solution that can grow alongside production requirements.

Selection Guide
The SGGZ-8 is an excellent choice for manufacturers seeking a balance between production efficiency, filling precision, and investment cost. With an output of 30–100 bottles per minute, it is particularly suitable for small- to medium-scale pharmaceutical production, nutraceutical manufacturing, and contract packaging operations that require frequent product changeovers.
Its compatibility with multiple bottle sizes allows a single machine to package different oral liquids, reducing the need for additional production equipment. Companies planning future expansion can also integrate the SGGZ-8 into a complete automated packaging line without replacing their existing filling system, making it a practical long-term investment.
