The sealing of drug packaging is one of the key factors affecting drug quality. With the increasingly strict regulation of the pharmaceutical industry, leak detection machines play an increasingly important role in the pharmaceutical industry. They not only ensure the quality and safety of drugs, improve production efficiency, and ensure the sealing of drug packaging, but also have traceability and data analysis functions, which comply with regulatory requirements. Therefore, pharmaceutical manufacturers are increasingly emphasizing the application of leak detection machines to ensure the stability and reliability of product quality, which also brings new opportunities to the leak detection machine industry.
From November 17th to 19th, 2024, the 65th (Autumn 2024) National Pharmaceutical Machinery Expo and the 2024 (Autumn) China International Pharmaceutical Machinery Expo (hereinafter referred to as the "Pharmaceutical Machinery Exhibition") were held at the Xiamen International Expo Center. Many leak detection machine manufacturers used the platform to showcase and promote their products. Among them, Haimen Jinjing Pharmaceutical Machinery Co., Ltd. (hereinafter referred to as Jinjing Pharmaceutical Machinery), which specializes in providing leak detection verification for the sealing of sterile drug packaging containers, also showcased heavyweight equipment such as ampoule leak detection machines and BFS blowing, filling, sealing and continuous discharge electronic leak detection machines at the Formulation Machinery Hall 2, booth number 10-94.

According to the data, the main products of Jinjing Pharmaceutical Machinery are online detection instruments such as infrared high-temperature radiation thermometers and intelligent digital display regulators. The products are widely used in industries such as metallurgy, steel, ceramics, non-ferrous metals, machinery, pharmaceuticals, and medical care, with users all over the country and have been exported to foreign markets.
In the field of ampoule leak detection, Jinjing Pharmaceutical Machinery occupies a place. The ampoule leak detection equipment produced by the company mainly includes HDA glass ampoule leak detection machine, HDP plastic ampoule leak detection machine, and HDI high-voltage electronic microporous leak detection machine. Among them, the HDA glass ampoule electronic micro hole leak detector is mainly used for leak detection of small water needles in 1ml, 2ml, 5ml, and 10ml glass ampoules, while the HDP electronic micro hole leak detector and HDI high-voltage electronic micro hole leak detector are mainly used for leak detection of individual plastic ampoules. The leak detection speed of the HDS soft bag electronic leak detector is 4500 bags/hour (conventional soft bags) and 1000 bags (dialysis soft bags), and the inspection electrode can be adjusted according to the requirements of the customer's inspection site.
Compared with some electronic micro hole leak detection machines on the market, the electronic micro hole leak detection machine produced by Jinjing Pharmaceutical Machinery does not pose a risk of secondary contamination in drug leak detection because it does not use dye or other liquids, and has higher leak detection accuracy. In addition, electronic micro hole leak detection machines have high safety. Due to the low electrical energy applied to the product and the short time, there are no side effects on the internal solution of the product. They can be used for leak detection of biological products such as vaccines and blood products. According to the different high voltage values that the drug packaging container can withstand, setting different high voltage values can also achieve non-destructive leak detection of the container. At present, this type of equipment can also adapt to various drug packaging containers, such as blow sealed plastic ampoules, glass ampoules, large infusion plastic bottles, large infusion soft bags, etc.
The electronic leak detection machine for BFS blow sealing and continuous discharge products is another device that uses an electronic leak detection machine. The BFS blow sealing and continuous discharge products are cut by the sealing machine and output into the automatic feeding machine of the leak detection machine. The products are automatically divided and transported to the inspection conveyor belt for processing. Then, they are immediately checked alternately through CH1, CH2, and CH3 high-voltage electrodes. Unqualified products are automatically removed by the removal device, and qualified products are discharged and sent to the next process. This device has advantages such as non-destructive online leak detection, the ability to install multiple high-voltage electrodes, high measurement data accuracy and good reproducibility, easy change of specifications and dimensions, and convenient cleaning and maintenance. It can be widely used in industries such as medicine.

Product Display
At the exhibition, the above-mentioned products exhibited by the company attracted the attention and consultation of many on-site visitors. Jinjing Pharmaceutical Machinery stated that in recent years, with the increasing attention to pharmaceutical and food safety, the company has invested a large amount of funds in the research and development of a series of high-frequency and high-voltage electronic micro hole leak detection machines, mainly used for leak sealing inspection of sterile liquid preparations in the pharmaceutical industry. The series of products include: HDI type high-voltage pinhole leak detection machine for 20ml oral liquid, HDS-2 type large infusion soft bag leak detection machine, HDR-1 type large infusion plastic bottle leak detection machine, HDB-2 type BFS series ampoule leak detection machine, HDA type glass ampoule electronic leak detection machine, HDS type non PVC co extruded film infusion soft bag fully automatic leak detection machine, and HDP type BFS infusion plastic bottle electronic leak detection machine. These devices will further meet the leak detection needs of the pharmaceutical packaging industry and assist in the high-quality development of the pharmaceutical industry.
It is worth mentioning that in August 2015, the company also participated as a review unit in the evaluation of the national pharmaceutical machinery industry standard "JB/T20170-2016 Injection Electronic Leak Detection Machine" by the Ministry of Industry and Information Technology. This not only reflects the company's strength and status, but also promotes technological innovation and development, enhances the company's image and brand value, strengthens industry exchanges and cooperation, and provides strong support for the sustainable development of the enterprise.
