In modern manufacturing, the appearance and functionality of electric scooters increasingly rely on their complex plastic shells. These shells are no longer simple covers but multifunctional components integrating structural support, aerodynamics, lighting installation, and even smart device interfaces. The quality of these shells, such as dimensional accuracy, seamless assembly, and surface finish, fundamentally depends on the "invisible hand" behind them—the injection molds. The precision and stability of these molds, in turn, hinge on the mold base (also known as the mold frame). As the skeleton of the entire mold, the mold base is composed of high-precision steel plates and standard components, and its manufacturing level directly determines the dimensional stability, part interchangeability, and overall load-bearing capacity of the final plastic product.

At this critical link in the precision manufacturing chain, Changhui Company has become a recognized "hidden champion" in the industry through its in-depth expertise in the mold base field. With over 40 years of experience, the company specializes in providing professional mold base solutions for various medium-to-large, high-precision plastic molds, die-casting molds, and cold-punching molds.

Changhui Company brings together over 100 experienced engineers and technical workers, forming a solid talent foundation. In terms of hardware, the company is equipped with more than 64 precision machining equipment, of which 35 advanced CNC machining centers constitute the core production capacity, ensuring efficiency and consistency throughout the entire process from rough to finish machining. To meet the needs of large or extremely high-precision mold bases, the company has dedicated large-scale and high-precision mold base production lines.

Dimensional accuracy is the lifeline of mold bases. Changhui Company can strictly control key dimensional tolerances within ±0.01mm to meet the requirements of ultra-high-precision applications such as gears and optical components. The company strictly adheres to the ISO9001 international quality management system, implementing rigorous management throughout each process: from cutting and blanking, rough and finish milling of planes and sides, to mold frame processing, deep hole/oblique hole drilling, and final fine edge grinding. The entire process is tightly controlled to ensure that every delivered mold base exhibits excellent dimensional stability and surface quality. The company is fully equipped with inspection facilities, including newly added imported coordinate measuring machines (CMMs) and other equipment, providing final verification for high precision.

To minimize customers' mold development cycles, Changhui Company maintains long-term inventories of large quantities of forged materials such as P20 and S50C. Additionally, the company offers a variety of mold steels, including high-quality domestic and imported grades like 2738, 718, NAK80, and H13, and provides corresponding material processing services, offering customers a one-stop solution for material selection and manufacturing. Its own raw material warehouse further shortens delivery times.

Changhui Company's mold base products are widely used in numerous industries such as automotive, home appliances, cosmetics, and stationery. Particularly in the manufacturing of molds for structurally complex plastic shells of electric scooters, its high-precision and high-stability mold bases lay the foundation for the superior quality of end products. The company was among the first in the domestic mold industry to obtain ISO9001 quality management system certification and enjoys a high reputation in the industry.

Changhui Company welcomes inquiries from mold manufacturers and partners in the automotive industry, and supports sample-based and drawing-based processing. It is committed to leveraging its professional mold base manufacturing capabilities to help customers create more competitive end products.
