How to control the size and shape accuracy of the pen mold?

The size and shape accuracy control of pen molds is a key link to ensure the manufacturing quality of pen products. Here are some of the main ways to control the size and shape accuracy of pen molds:

1. High-precision processing equipment: using advanced CNC machining centers and EDM machine tools and other equipment, which can accurately control the cutting parameters and processing paths to ensure the machining accuracy of mold parts.

2. High-quality mold materials: Choosing mold materials with high strength, high wear resistance and good thermal stability, such as high-quality alloy steel or cemented carbide, can reduce the size and shape errors caused by deformation or wear during the use of the mold.

3. Strict quality inspection: In the process of mold processing, strict quality inspection is implemented, including size measurement, shape inspection, etc., to ensure that each step of processing meets the design requirements. At the same time, the finished mold is comprehensively tested to ensure that the overall accuracy of the mold meets the requirements.

4. Reasonable mold structure design: In the mold design stage, fully consider the shape, size and process requirements of the product, and reasonably design the cavity, gate, cooling system and other structures of the mold to reduce the processing difficulty and error accumulation.

To sum up, a variety of measures need to be taken to control the size and shape accuracy of the pen mold during the mold processing process. Mold design, material selection, CNC machining, precision grinding, heat treatment, inspection and measurement, and quality management all need to be fully considered and implemented. Through reasonable control measures and effective quality management, the dimensional and shape accuracy of the mold can be ensured, and the quality and dimensional stability of injection molded products can be improved.
