The raw materials of the pen refill mainly include graphite, binder, pigment, and other additives. Graphite is the main raw material of the pen refill, which provides the color and texture for writing. The binder is used to firmly bind the graphite and other components together, making the pen refill have good writing performance. In addition, the addition of pigments and additives can improve the color, lubricity, and durability of the pen refill. III. Production Process 1. Raw Material Preparation: Firstly, mix the selected raw materials in a certain proportion, through grinding, screening and other processes to obtain the raw material powder that meets the production requirements. 2. Mixing and Stirring: Put the raw material powder, binder, and other additives into a mixer for sufficient mixing and stirring to evenly distribute each component. 3. Extrusion and Molding: The mixed raw materials are extruded into a certain shape of pen refill through an extruder, then dried and cured to give the pen refill a certain hardness and strength. 4. Cutting and Assembly: The cured pen refill is cut and polished, then assembled with a pen tip to form a complete pen refill product. IV. Related Knowledge 1. Types of Pen Refills: There are many types of pen refills according to different purposes and market demands, such as ballpoint pen refills, gel pen refills, and pencil leads. 2. Improvement of Production Technology: With the development of technology, production technology continues to improve, which enhances the writing performance and durability of the pen refill. For example, optimizing the raw material formula and improving production equipment can improve the lubricity and water resistance of the pen refill. 3. Environmental Protection and Sustainable Development: In the production process, many manufacturers focus on environmental protection and sustainable development, using environmentally friendly materials and processes to reduce pollution and energy consumption during production. At the same time, recycling used pen refills has become an environmental trend.
