Filling machine is the core equipment in pharmaceutical production, and its performance directly affects the quality and production efficiency of drugs. In recent years, the global filling machine market has steadily grown, with a scale of 7.462 billion yuan in 2023 and expected to grow to 8.518 billion yuan in 2029. Although China's filling machine industry started late, through technology introduction and independent innovation, equipment performance continues to improve and domestic substitution accelerates. At present, filling machines are rapidly iterating towards intelligence, sterility, energy conservation, environmental protection, and customization.
The 66th (Spring 2025) China International Pharmaceutical Machinery Expo and the 2025 (Spring) China International Pharmaceutical Machinery Expo are about to grandly kick off, with numerous filling machine manufacturers gathering at the exhibition. Among them, Nantong Bolang Machinery Technology Co., Ltd. (hereinafter referred to as Bolang Machinery) will showcase its strength and style to the industry with its exquisite products and innovative technologies.

Adhere to quality with craftsmanship and build reputation with details
Bolang Machinery, formerly known as Nanhong Pharmaceutical Machinery Factory in Haimen City, Jiangsu Province, has been deeply involved in the fields of pharmaceutical machinery and food machinery for many years, accumulating a profound foundation and good reputation in the industry. The "Nanhong" brand has a profound influence in the national pharmaceutical industry. Its products are not only distributed throughout the country, but also exported to multiple countries and regions such as Asia, America, and Europe, becoming a trusted partner for many pharmaceutical, health product, and food enterprises.
The company has a professional and strong team with over 80 employees, including 9 engineering and technical personnel, including 1 senior engineer, 3 engineers, as well as 1 GMP certified process technician and 1 QS certified process technician. This talent allocation provides a solid guarantee for the company's product research and development, production and manufacturing, and quality control.
In terms of product quality control, Bolang Machinery has put in a lot of effort. The company strictly adheres to the Good Manufacturing Practice (GMP) and GB/T19000-ISO9000 "Quality Management and Quality" series standards, and has established a quality monitoring team composed of senior engineers, GMP process personnel, and technical leaders from various departments. The quality veto system is implemented to ensure that every product meets high standards.
In the material selection process, the company strives for excellence. For parts that come into contact with chemicals in various packaging equipment, engineering plastics, glass, or 316L stainless steel materials that have undergone physical and chemical testing are used, which are non-toxic, corrosion-resistant, and pollution-free. The quality assurance certificate, steel grade, and furnace number of stainless steel materials are strictly checked. The countertop and other surface components are also made of high-quality stainless steel materials such as 1Gr18Ni9Ti, which can prevent corrosion and rusting during the production process from the source.
In the process of whole machine production, the company not only formulates strict enterprise production standards, but also actively references national standards such as GB6168, GB5226, GBT13306, GB/T13384, as well as industry standards such as YY0056, YY0131, YY/T0076 to standardize products and ensure that they meet GMP requirements.
After the product production is completed, the company needs to conduct a series of strict inspections, including appearance quality, size, no-load test, sealing, temperature rise, electrical safety performance, load test, production capacity, power inspection, cleaning quality, high temperature sterilization quality, loading error, damage rate, capping qualification rate, capping quality, labeling qualification rate, labeling quality, bottle temperature, noise and other multiple items. Once non-conforming items are found, the technical team led by the chief engineer will immediately analyze, identify the root cause of the problem, and solve it in a timely manner until the product is inspected and qualified before leaving the factory. This relentless pursuit of quality has enabled the company's products to maintain strong competitiveness in the market.
double“wisdom”Sharp tools appear, empowering efficient production
At the 66th Pharmaceutical Opportunity, the company will showcase two heavyweight products. Among them, the oral liquid high-speed filling machine, as the filling host in the oral liquid production line, is full of highlights. This equipment is mainly used for filling, capping, and sealing straight tube bottles with 5-30ml easy to pull caps (or aluminum-plastic caps). It adopts screw feeding method, which ensures stable and reliable bottle delivery process, effectively avoiding bottle jamming and damage during transportation; The application of local tracking filling technology can accurately control the filling volume, which is not easy to produce foam, ensuring the filling accuracy and product quality; The electromagnetic oscillation cover feeding device greatly improves the coverage rate and reduces the complexity and errors of manual operation. This filling machine combines filling and sealing functions into one, with an avant-garde design concept and a compact and reasonable structure, which not only saves space but also improves production efficiency. Its production capacity can reach 80-100 bottles per minute, with a sealing rate of ≥ 99%. The power supply is a 380V, 50Hz three-phase four wire system with a power of only 1.3Kw, which not only achieves efficient production but also has energy-saving advantages.

Oral liquid high-speed filling machine
Another liquid filling production line exhibited should not be underestimated. This production line is suitable for quantitative filling of plastic bottles such as syrup, oral liquid, and paste. It mainly consists of automatic bottle feeding machine, automatic bottle sorting machine, air washing machine (optional), automatic filling machine, adhesive labeling machine, etc., realizing one-stop automated production from bottle conveying, cleaning, filling to labeling. Its production capacity is 5000-10000 bottles/hour, suitable for 50-500ml plastic bottles, with a filling accuracy controlled at 0-2%, an air consumption of 0.4m ³/min, a pressure of 0.4-0.5MPa, a power supply of 380v 50Hz three-phase four wire system, and a total line power of 6.5Kw. This production line not only has high production efficiency, but also can accurately control the filling volume to ensure consistency in product quality, while also having good energy-saving performance and stable operating status.

Full process service escort, jointly embarking on a new journey in the industry
It is worth mentioning that in addition to high-quality products and advanced technology, the company also places great emphasis on technical and after-sales services. At the time of product delivery, the company will provide detailed technical user manuals, vulnerable parts lists, operation guides, repair and maintenance manuals, and other technical materials to enable users to quickly familiarize themselves with and master the use of the equipment. At the same time, the company will dispatch professional technicians to conduct equipment debugging and guide users in operation and maintenance, ensuring that users can smoothly enter production.
In terms of after-sales service, the company promises a one-year warranty and lifetime service. No matter when or where the equipment malfunctions, the company guarantees to arrive at the site for maintenance within 24 hours in our province and 48 hours in other provinces, minimizing production losses for users to the greatest extent possible.
In addition, the company also provides corresponding GMP verification software materials to assist customers in ensuring that their equipment can pass GMP certification smoothly, truly solving problems for users.
At the upcoming 66th Pharmaceutical Opportunities, the company will showcase its high-quality products, exquisite technology, and attentive service at the N7-65 booth in the Formulation Machinery and Equipment Hall 2, providing customers with a stunning visual and technical experience. I believe that this exhibition is not only a good opportunity for the company to showcase itself, but also injects new vitality into the development of the pharmaceutical industry, promoting the industry to move towards higher quality and intelligence!
