This project was developed for a U.S.-owned factory in Iran in the health supplement industry. The customer needed an automatic milk powder filling machine solution for metal tins and cans, with a strong focus on filling accuracy, production stability, food safety control, and reduced product waste.
eixpack provided a customized automatic filling line based on the customer’s milk powder characteristics. The system includes UV can sterilization, raw material metal detection, dual servo auger weighing filling, automatic spoon dropping, capping, and cleaning support. The project target was to achieve 500g filling accuracy within ±0.5% while improving automation from can sterilization to final capping and sealing.
For similar powder packaging applications, customers can also explore eixpack’s powder filling machine solution or general filling machine product range.
The customer’s previous filling process could not maintain stable filling accuracy. For 500g milk powder cans, inaccurate filling may lead to overfilling, product giveaway, underweight risk, and inconsistent customer experience.
Unstable packaging efficiency made it difficult for the customer to plan output, labor allocation, and delivery schedules. For contract manufacturers and brand manufacturers, unstable production can directly affect order fulfillment reliability.
Milk powder is a high-value powder product. Product loss during filling, dust generation, and inaccurate dosing can increase long-term packaging costs and reduce production profitability.
The customer required a more automated line covering can sterilization, filling, spoon dropping, capping, and sealing-related operations. Higher automation helps reduce manual handling, improve hygiene control, and make production more consistent.
For milk powder and health supplement products, food safety is a critical requirement. The customer needed metal detection to help reduce contamination risk and strengthen quality control before final packaging.
The main goal of this project was to build a fully automatic milk powder filling machine line for metal tins and cans. The customer expected the system to improve 500g filling accuracy to ±0.5%, increase production efficiency, reduce product waste, and support automated operation from can sterilization to final capping and sealing.
Another important goal was to improve food safety control by adding raw material metal detection and reducing unnecessary manual contact during the production process.
eixpack provided a customized milk powder filling machine solution for metal tins and cans. The system was designed around the customer’s product characteristics: powder form, moisture sensitivity, caking risk, and the need for quantitative filling accuracy.
The line includes UV can sterilization before filling. This module helps improve hygiene control before the product enters the container, making it suitable for milk powder, health supplement powders, and other powder products with high cleanliness requirements.
A raw material metal detection module is included to help identify potential metal contamination before the product reaches the filling stage. This supports food safety control and reduces quality risks in the final packaged product.
The filling section uses dual servo auger weighing filling with large and small dosing units. The large auger supports fast main filling, while the smaller dosing unit supports fine adjustment. This structure helps balance filling speed and accuracy, especially for 500g milk powder cans requiring ±0.5% target accuracy.
The automatic spoon dropping module reduces manual placement and helps improve production consistency. For milk powder packaging, this function is useful when a measuring spoon needs to be inserted into each tin or can.
The capping machine supports automatic cap placement and closing after filling and spoon dropping. This helps reduce manual handling, improve packaging consistency, and support continuous production.
The cleaning system combines air shower and sweeping functions to help remove powder residue around the container and line area. This is important for milk powder applications because powder dust can affect cleanliness, machine stability, and package appearance.
This solution works because it is designed around the real production challenges of milk powder packaging. Milk powder requires controlled filling, hygienic handling, stable dosing, and protection from unnecessary contamination risks. The system addresses these needs by combining UV can sterilization, metal detection, servo auger weighing filling, automatic spoon dropping, capping, and cleaning support.
For contract manufacturers, brand manufacturers, food manufacturers, powder product manufacturers, and sports nutrition brands, this type of automatic filling solution helps improve production consistency, reduce labor dependence, and prepare the production line for future expansion.
For this customized milk powder filling machine project, eixpack can provide full technical support from early requirement analysis to final project delivery. Our service process can include requirement analysis, packaging sample evaluation, machine selection, line layout design, installation preparation, commissioning support, operator training, maintenance guidance, spare parts support, and future automation upgrade planning.
For this type of automatic powder filling line, eixpack technical engineers can visit the customer’s factory for on-site installation, commissioning, testing, and operator training. During the on-site service, our engineers help check machine installation conditions, adjust the filling system, test line coordination, verify key functions, and train the customer’s operators on machine operation, daily maintenance, cleaning procedures, troubleshooting, and production safety.
Because milk powder is moisture-sensitive and prone to caking, correct installation, parameter adjustment, and operator training are especially important. On-site commissioning helps ensure that the UV can sterilization, raw material metal detection, dual servo auger weighing filling, automatic spoon dropping, capping machine, and cleaning system work together as a stable production line.
After installation and training, eixpack can continue to provide remote or on-site technical support according to customer requirements. Spare parts support, maintenance guidance, and future automation upgrade recommendations can also be provided to help the customer maintain stable long-term production.
The automatic milk powder filling line helped us improve filling consistency and reduce the pressure on manual operation. The system design matched our production requirements, especially the dual servo auger filling structure and integrated metal detection. eixpack also provided responsive technical support during project communication and line preparation.”
