Meeting the Filling Needs of Small and Medium Pharmaceutical Factories

Small and medium-sized pharmaceutical manufacturers producing oral liquids, syrups, and eye drops face a distinct set of operational challenges. These products demand precise dosing, strict hygiene control, and consistent output quality, yet many factories still rely on manual or semi-automated processes that struggle to meet these requirements. Shengqi Packaging Machinery, a company founded in 2004 with headquarters in Shanghai (Jinshan) and Suqian, Jiangsu, has positioned itself as a provider of high-end automated packaging equipment and industrial robots designed to address exactly these pain points.

The company’s strategic focus centers on integrated "smart factory" solutions that reduce labor dependency, eliminate inconsistent manual production quality, and lower contamination risks in sterile environments—issues that are particularly acute for producers of liquid pharmaceutical formulations such as oral liquid syrup and eye drops.

Why Liquid Filling Precision Matters for Oral Liquids, Syrups, and Eye Drops

Oral liquid, syrup, and eye drop production requires filling accuracy that manual operations often cannot guarantee. Inconsistent filling volumes and contamination risks are the two primary target scenario pain points that Shengqi’s Liquid Filling Production Lines are engineered to solve.

High-Precision Dosage Control

Shengqi’s liquid filling systems achieve dosage accuracy through servo peristaltic and ceramic pump technology. This high-precision filling approach ensures that each unit—whether a bottle of oral liquid, a syrup container, or a small-volume eye drop vial—receives a consistent, accurate fill volume, which is critical for both regulatory compliance and patient safety.

Integrated Hygiene and Finishing Steps

The production line incorporates several sequential features that work together to protect product integrity:

• Automatic bottle sorting: Organizes containers for processing, which reduces manual handling and the associated risk of contamination.
• Air rinsing: Cleans bottles before filling to ensure hygiene standards are met prior to dosing.
• Capping and labeling: Integrated finishing steps streamline production by combining sealing and identification into a single continuous process.

These features are particularly relevant to small-format medical containers. For vial filling in the 10–100 mL range, Shengqi’s equipment includes automated stoppering, which maintains sterility—an essential requirement for medical preparations and vaccines that share production logic with eye drop and oral liquid lines.

Industry Adaptation Across Pharmaceutical, Chemical, and Food & Beverage Sectors

Shengqi’s Liquid Filling Production Lines are adapted for use across the pharmaceutical, chemical, and food & beverage industries. This cross-industry adaptability reflects the underlying versatility of the servo peristaltic and ceramic pump filling technology, which can be configured for different viscosities and container formats without compromising dosage accuracy.

Beyond general liquid filling, Shengqi also offers specialized filling lines tailored to specific medical and pharmaceutical liquid categories:

• Saline Solution Filling: Positioned as specialized medical saline processing, adapted for pharmaceutical manufacturing.
• Disinfectant Filling: A high-speed chemical liquid packaging solution serving both chemical and healthcare industries.
• Dialysis Buffer Solution Filling: Specialized medical solution processing designed for medical device and pharmaceutical manufacturers.

This breadth of specialized filling lines demonstrates that Shengqi’s core liquid filling platform—built around precision pumping and integrated hygiene control—extends naturally to the varied requirements of oral liquid syrup and eye drop production, as well as adjacent medical liquid categories.

Sterile Environment Compliance: GMP and Class 100 Laminar Flow

Contamination control is a defining requirement for oral liquid, syrup, and eye drop manufacturing, particularly where products are intended for direct human consumption or ophthalmic use. Shengqi’s systems are designed for Class 100 laminar flow and GMP compliance, and the company holds GMP compliance certification along with adherence to Class 100 laminar flow protection standards.

This sterility assurance capability is demonstrated in Shengqi’s COC Syringe Assembly line, which was engineered as a fully automated line with Class 100 laminar flow protection for a sterile pharmaceutical production project. The same underlying platform capability—compatibility with Class A cleanroom standards and sterile production environments—applies to liquid filling operations for oral liquid syrup and eye drop products, where minimizing human contact with the product stream is essential.

Automation That Reduces Labor Dependency

One of the central value propositions behind Shengqi’s equipment is the reduction of labor requirements without sacrificing throughput. In documented cases, the company’s automation has reduced staffing needs from 35 personnel to 1 in specific sorting scenarios, and separately saved 8–10 staff members while doubling efficiency in an environmental protection industry packaging project. While these particular cases originate from hardware sorting and RO membrane packaging applications, they illustrate the broader capability set—vision-guided systems, PLC intelligent control, and HMI integration—that underpins Shengqi’s approach to automated production across its product lines, including liquid filling for pharmaceutical use.

The company’s proprietary technology platform combines PLC intelligent control with HMI integration, allowing real-time equipment monitoring and control. This data processing capability is designed to meet stringent GMP regulatory data and operational standards, giving small and medium pharma factories a pathway to compliant, traceable automation without needing to build such systems independently.

Full-Service Delivery for Pharmaceutical Manufacturers

Shengqi’s service model integrates research and development, design, production, assembly, and after-sales support into a single offering. For small and medium pharmaceutical factories evaluating an oral liquid syrup or eye drop filling line, this means access to:

• Non-standard solution customization: Equipment configurations adapted to specific product and container formats.
• Workshop space optimization: Line layouts designed to fit existing facility constraints.
• Technical maintenance: Ongoing support delivered through an integrated after-sales service team.

The company’s delivery capability extends to global markets, with manufacturing bases in Shanghai and Jiangsu supporting export operations across North America, South America, Southeast Asia, Australia, Europe, and Africa. This global delivery and installation capability means pharmaceutical manufacturers outside China can access the same GMP-compliant, high-precision filling technology used domestically.

A Track Record Built Since 2004

Since its establishment in 2004, Shengqi Packaging Machinery has expanded to a 15,000 square meter production base and launched the Zihoo Robot brand for proprietary industrial robotics. The company has been recognized as a High-Tech Enterprise and as one of Shanghai’s "Specialized, Refined, Unique, and Innovative" Enterprises, credentials that reflect its sustained investment in independent research and development of industrial robots and vision-guided systems.

For small and medium pharmaceutical factories seeking a filling production line capable of handling oral liquids, syrups, and eye drops under strict hygiene and dosage accuracy requirements, Shengqi Packaging Machinery offers a combination of specialized liquid filling technology, GMP and Class 100 laminar flow compliance, integrated automation control, and full-service delivery—all built on nearly two decades of dedicated development in automated packaging equipment.
