I. Design Stage Design is the first step in the manufacturing process, determining the performance, shape, and function of the product. For pencils, design mainly involves the shape, color, and material of the pencil barrel, as well as the hardness and color of the lead. Designers meticulously design pencils based on market demand and user habits. They not only consider the aesthetic appearance of the pencil but also ensure its practicality and comfort. II. Manufacturing Stage 1. Raw Material Preparation: The main raw materials for pencils are wood, leads, and paints. The wood needs to be sorted, cut, and dried to ensure its quality and stability. The lead is produced through mixing graphite and clay under high temperature and pressure. 2. Barrel Processing: The processed wood is cut, polished, and spliced to form the pencil barrel. In this process, technicians precisely control the size and shape of each pencil barrel to meet design requirements. 3. Lead Production: The production of leads is a critical step in pencil manufacturing. Graphite and clay are mixed in a certain proportion and placed in a specialized mold, which is then processed under high temperature and pressure to form the lead. This process requires precise control of the proportion of graphite and clay, as well as processing temperature and pressure, to ensure the hardness and color of the lead. 4. Assembly and Coloring: The finished barrels and leads are assembled, followed by coloring treatment for the barrels. In this process, technicians precisely control the thickness and uniformity of the coating to ensure the aesthetic and practicality of the pencil. III. Quality Inspection Completed pencils need to undergo quality inspection, including checking the appearance, size, lead hardness, color, and other indicators to ensure they meet design and manufacturing requirements. Any unqualified products will be eliminated and re-manufactured. IV. Packaging and Sales Pencils that pass quality inspection are packaged and sold in various markets. Packaging not only protects and displays the product but also increases its added value. Finally, these pencils are delivered to consumers through various channels, providing convenience for their studies, work, and daily lives.
