Prepare the raw materials such as pen barrels, refills, and tips. The pen barrels are usually made of plastic or metal materials, while the refills are mainly composed of ink and tips. 2. Pen barrel processing: Cutting, injection molding, grinding and other processes are performed on the prepared pen barrel materials to ensure that the length, diameter, and other dimensions meet the requirements. 3. Pen tip processing: The processing of pen tips is a key part of the ballpoint pen production process, including casting, grinding, and assembly steps. It is necessary to control the composition and temperature of the metal during casting to ensure the hardness and wear resistance of the pen tip. During the grinding process, it is necessary to ensure that the track for the ball to run is smooth for smooth writing. 4. Refill production: The refill is the "ink" part of the ballpoint pen, mainly composed of ink and tip. The formula of ink is one of the key technologies in the production process of ballpoint pen, which directly affects the writing effect and durability. It is necessary to strictly control the viscosity, color, and fluidity of the ink during production. The processing of the tip needs to ensure its close cooperation with the ball to ensure smooth writing. 5. Assembly and quality inspection: The processed pen tips, refills, and pen barrels are assembled to form a complete ballpoint pen. Then strict quality inspections are conducted, including appearance checks and writing tests to ensure that the product meets quality standards. Key points in production process: 1. Material selection: Choosing suitable raw materials is the foundation for ensuring the quality of ballpoint pens. 2. Processing accuracy: The processing accuracy of each process directly affects the performance and lifespan of the product. 3. Ink formula: The formula of ink is a core technology in the production process of ballpoint pens, which requires strict control of the viscosity, color, and fluidity of the ink. 4. Quality inspection: Strict quality inspection is the key to ensuring product quality, and each process needs to be strictly controlled. Through this analysis, we hope to provide a better understanding of the production process of ballpoint pens and help improve product quality
