Preparation of raw materials The manufacturing process of a ballpoint pen starts with the preparation of raw materials. The main raw materials include the pen barrel, refill, ink, and decorative accessories, etc. These raw materials need to be subject to strict quality testing and screening to ensure the quality of the finished product. II. Cutting and processing Next, according to design requirements, the raw materials are cut and processed. This includes cutting, bending, and drilling of the pen barrel, as well as the production of the refill. For plastic pen barrels, this usually involves injection molding; for metal pen barrels, mechanical cutting and polishing processes are required. III. Assembly and fitting After completing the cutting and processing of raw materials, the next step is assembly and fitting. This includes inserting the refill into the pen barrel, installing accessories such as clip and cap, and filling the ink into the refill. This step requires precise operation and quality control to ensure smooth writing and aesthetics of the ballpoint pen. IV. Quality inspection After assembly, the ballpoint pen needs to be inspected for quality. This step mainly involves checking the writing performance and appearance quality of the ballpoint pen. This includes checking the writing smoothness of the refill, the color and drying time of the ink, as well as any scratches or color differences on the appearance of the pen barrel. Only ballpoint pens that pass quality inspection can be considered as qualified products. V. Packaging and finished product
