In the precision plastic mold industry, USB housing molds demand exceptionally high requirements for the manufacturing quality of mold bases due to their compact structure and stringent dimensional accuracy. As the foundational support structure of USB housing molds, the precision, strength, and thermal stability of the mold base directly determine the final product’s molding quality, production efficiency, and mold lifespan.
High-Precision Manufacturing to Meet the Stringent Demands of Miniature Plastic Parts
USB housings are small, precision plastic components. Their mold bases require extremely high dimensional accuracy, structural rigidity, and fit tolerances. Leveraging its advanced CNC machining centers and high-precision inspection systems, Changhui Company ensures that key fit dimensions of mold bases are consistently controlled within a tolerance level of ±0.01mm, meeting the core requirements of USB housing molds for high surface finish, flash-free edges, and precise assembly.
Through full-process precision control—from material cutting, rough milling, fine milling, deep-hole drilling to final fine grinding—every step adheres to the ISO9001 quality management standard. This ensures the flatness, parallelism, and hole position accuracy of the mold base fully meet the production conditions for precision injection molding, laying a solid foundation for the batch production and consistency of USB housings.
Professional Materials and Processes to Ensure Mold Longevity and Stability
USB housing molds typically endure long-term, high-frequency injection cycles, demanding high wear resistance, fatigue resistance, and thermal stability from the mold base. Changhui Company maintains a long-term inventory of high-quality mold steels such as P20, 718, S136, and NAK80. The most suitable material can be selected based on customer needs to ensure the mold base resists deformation and wear under prolonged high-temperature and high-pressure conditions.
The company’s advanced equipment, including deep-hole drilling machines, large horizontal machining centers, and CMMs, enables efficient processing of key structures such as complex cooling channels, precision guide holes, and ejection systems. This significantly enhances the cooling efficiency and ejection stability of USB housing molds, shortens the injection cycle, and improves production efficiency.
One-Stop Mold Base Solutions, Supporting Customization and Fast Delivery
Whether for standard USB housing mold bases or non-standard ones featuring complex structures, multi-layer sliders, or special hot runner interfaces, Changhui Company can provide customized development and manufacturing based on customer-provided 3D drawings or physical samples. With its own raw material warehouse and multiple high-precision production lines, the company can significantly shorten lead times and flexibly meet customer requirements for trial production and mass production schedules.
