Introduction In daily life and study, pen refills are undoubtedly one of the most commonly used stationery items. From simple pencil leads to high-tech electronic pen refills, they all play an important role. So, how does a pen refill go from raw materials to a tool in our hands? Next, we will take you into the magical world of pen refills, providing a comprehensive analysis from manufacturing to use. II. Manufacturing Process of Pen Refills 1. Raw Material Preparation: The manufacturing of pen refills starts with the preparation of various raw materials such as graphite, clay, polymers, etc. These raw materials are carefully selected and processed to meet specific manufacturing requirements. 2. Mixing and Stirring: The selected raw materials are mixed in a certain proportion and then uniformly stirred using a mixer to ensure that the various ingredients are fully fused. 3. Extrusion and Molding: The mixed material is extruded through an extruder to form pen refills of a certain shape and size. This step requires strict control of temperature and pressure to ensure the quality of the pen refill. 4. Drying and Curing: The extruded pen refills need to be dried and cured to make their shape and performance more stable. This step usually requires certain temperature and humidity conditions. 5. Quality Check and Packaging: After completing the drying and curing process, the pen refills need to be inspected for quality. Qualified pen refills will be packaged and ready for sale in the market. III. Use Process of Pen Refills 1. Purchasing and Unpacking: After purchasing pen refills, consumers need to take them out of the packaging. At this time, the tip of the pen refill is usually wrapped in a protective film that needs to be torn off for use. 2. Writing and Drawing: After tearing off the protective film, the pen refill can be used for writing or drawing. In this process, we need to master appropriate force and angle to ensure smooth writing and drawing effect. 3. Maintenance and Replacement: As the time of use increases, the pen refill will gradually wear out. At this time, we need to maintain or replace the pen refill with a new one to maintain smooth writing and drawing effect. IV. Conclusion

From manufacturing to use, the world of pen refills is full
