Liquid filling and sealing machine is a highly integrated automatic production equipment that integrates liquid metering, precise filling, packaging forming, heat sealing, and cutting functions, realizing the unmanned automatic operation of the entire process from liquid material input to finished product output, and is a core device in the automatic packaging production line of liquid products in cosmetics, food, medicine, and daily chemical industries, especially suitable for the mass production of small package liquid products such as sachets and small bags. Discus (Shenzhen) Technology Co., Ltd., with profound technical accumulation in the field of filling and packaging equipment and in-depth research on the market demand of liquid product packaging, has developed a series of liquid filling and sealing machines with high efficiency, high precision, and strong adaptability, which have the characteristics of structure stabilization, complete degassing, and density fixed, ensuring the stable and uniform quality of the filled and sealed products. The equipment adopts an advanced PLC control system and a high-precision servo drive system, which can realize the precise control of each link of the filling and sealing process, with a filling volume error controlled within ±0.5ml and a sealing position error controlled within ±0.1mm, meeting the strict quality requirements of high-end liquid product packaging. The liquid filling and sealing machine is equipped with a high-performance liquid metering pump and a multi-channel filling head, which can realize the simultaneous filling of multiple packages, with a production capacity of up to 600 packages per minute, greatly improving the production efficiency of the production line, and the filling head is designed with anti-dripping and anti-foaming functions, avoiding liquid waste and packaging pollution. The equipment can adapt to various packaging materials such as PE film, aluminum-plastic composite film, and non-woven fabric, and can realize the packaging of different bag types and specifications by replacing different forming molds, heat sealing heads, and cutting knives, including small sachets of 5ml-20ml for single use and large bags of 500ml-1000ml for family use, meeting the diverse packaging needs of liquid products such as shampoo, facial toner, edible oil, and medical liquid. The heat sealing part of the equipment adopts a high-frequency heat sealing technology and a constant temperature control system, which can realize the uniform heating and firm sealing of the packaging, and the sealing temperature and pressure can be steplessly adjusted according to the characteristics of the packaging materials, avoiding the problems of incomplete sealing and packaging rupture caused by improper temperature and pressure. All parts of the machine in contact with liquid are made of food-grade 304 stainless steel, which meets the hygiene and safety requirements of food, cosmetic, and pharmaceutical production, and the whole machine is designed with a closed structure to prevent dust and impurities from entering the production process, ensuring the purity of the liquid products. The liquid filling and sealing machine is equipped with a complete set of automatic detection and protection systems, including material shortage detection, film shortage detection, sealing failure detection, and overload protection, which can automatically stop the machine and give an alarm when an abnormality occurs, avoiding product waste and equipment damage, and the equipment is also equipped with an automatic counting function, which can accurately count the output of finished products, facilitating the enterprise's production management. In practical application, the liquid filling and sealing machine is widely used in large and medium-sized daily chemical enterprises, food processing enterprises, and pharmaceutical enterprises, especially in the Southeast Asian, South Asian, and African markets where small package liquid products are in high demand. A Thai customer who visited the company in July 2024 adopted the equipment for the production line of small sachet shampoo and facial toner, realizing the automatic filling and sealing of small package products, with a production capacity of 400 sachets per minute, and the product qualification rate reached 99.9%, which greatly improved the enterprise's market competitiveness. The company can customize the liquid filling and sealing machine according to the specific product characteristics, packaging requirements, and production scale of customers, and provide professional technical guidance, equipment debugging, and after-sales maintenance services to ensure the stable and efficient operation of the equipment. With advanced technology, reliable quality, and strong customization capabilities, the liquid filling and sealing machine of Discus (Shenzhen) Technology Co., Ltd. has become an important equipment for enterprises to realize the mass production and intelligent packaging of liquid products.
