However, the manufacturing process and materials behind it are rarely known. This article will reveal the manufacturing process and materials used in the production of ballpoint pens. II. The Manufacturing Process of Ballpoint Pens 1. Design Stage Before starting the manufacturing process, designers will conduct the design work. This stage involves the design of various parts such as the body, cap, tip, and so on, including their shapes, colors, and materials. Designers will consider user needs, aesthetics, and manufacturing feasibility. 2. Raw Material Preparation According to the design requirements, the corresponding raw materials are prepared. The main raw materials for ballpoint pens include plastic, metal, and ink. plastic is used to make the body and cap, metal for the tip and spring parts, and ink is the core of ballpoint pen writing. 3. Processing and Assembly The processing stage mainly includes cutting, grinding, injection molding, pressing, and other processes on raw materials. Then, the processed components are assembled to form a complete ballpoint pen. 4. Quality Control After assembly, a strict quality check is conducted to ensure that each pen meets quality standards. The inspection includes the smoothness of the tip, the color of the ink, the durability of the body, and so on. III. Exploring the Materials of Ballpoint Pens 1. plastic The body and cap of a ballpoint pen are mostly made of plastic. plastic is a desirable material for manufacturing ballpoint pens due to its lightweight, durability, and ease of processing. Common plastic materials include polyethylene, polypropylene, ABS, and so on.

2. Metal
