First, the technological content of pen refills is mainly reflected in their material science and manufacturing processes. Modern pen refills mostly use polymer materials, which have excellent physical and chemical stability, ensuring the durability and smooth writing of the refill. Additionally, the manufacturing process involves precise mechanical processing and electronic control technology to ensure product accuracy and consistency. Secondly, the manufacturing process of pen refills includes the following steps: 1. Material preparation: The first step in the manufacture of pen refills is to prepare the required polymer materials and other auxiliary materials. These materials need to be rigorously screened and inspected to ensure their quality and performance meet the required standards.

2. Mixing and injection molding: The processed materials are mixed in a certain proportion and then injected into the initial shape of the pen refill through an injection molding machine. This process requires precise control of temperature and pressure to ensure the accuracy of pen refill size and shape. 3. Processing and assembly: The injected pen refill needs further processing and assembly, including trimming, grinding, and assembling the pen tip to complete the initial finished product of the pen refill. 4. Quality inspection: The processed and assembled pen refills need to undergo rigorous quality inspections, including inspecting the appearance, size, and writing performance of the pen refill to ensure they meet quality standards. 5. Packaging and shipping: The pen refills that pass quality inspections will be packaged as finished products and shipped for sale. 这就是笔芯的科技与制造过程的揭秘。每一个精致的笔芯背后，都蕴含着科技的力量和匠人的智慧。
