In traditional perception, wheel hub manufacturing is often associated with heavy casting equipment and high-temperature forging scenes. However, with the advancement of automotive lightweight trends, the injection molding process is demonstrating unique value in the manufacturing of specific wheel hubs.

The precision of the mold base (also known as the mold frame) is a core indicator for measuring mold manufacturing standards, directly affecting the dimensional stability, interchangeability, sealing, and load-bearing capacity of the final product. The mold base serves as the skeleton of the entire mold set, consisting of steel plates and components.

By integrating advanced processing and inspection equipment, we can efficiently complete the entire workflow from rough machining to precision machining, meeting customers' stringent requirements for product accuracy, surface finish, and delivery timelines, thereby casting exceptional quality.

Changhui Company's Professional Team: Possesses over 100 experienced engineers and technical workers.

Advanced Manufacturing: Equipped with more than 64 precision machining equipment, including 35 advanced CNC machining centers that form our core production capacity, ensuring machining accuracy and consistency.

We have our own raw material warehouse to shorten delivery times, and we possess high-precision production and large-scale mold base manufacturing equipment, capable of meeting diverse product requirements for large or precision mold bases.

Dimensional Accuracy: The degree of conformity between the actual machined dimensions and the design dimensions, typically controlled by dimensional tolerances. In high-precision scenarios (such as gears, optical components), tolerances can be controlled within ±0.01 mm.

The company specializes in producing various medium to large-sized, high-precision plastic molds, die-casting molds, and cold stamping molds' professional mold bases. It adopts industry-leading processing techniques and is fully equipped with inspection facilities. New additions include imported coordinate measuring machines, horizontal machining centers, and large mold base production lines, as well as new high-precision mold base production lines. Products cater to various industries such as automotive, home appliances, cosmetics, stationery, etc., for medium to large-sized precision mold bases. The company was among the first in the domestic mold industry to pass the ISO9001-2000 quality management system certification and enjoys a high reputation within the industry.

Production strictly adheres to the ISO9001 international quality management system, with rigorous management throughout every process. From material cutting, rough milling of planes and sides, six-sided chamfering, rough cavity machining, precision plane milling, precision side edging, deep hole/mold cavity/angled hole machining, to template precision edging and grinding, the entire process ensures high precision and quality.

The company maintains long-term inventories of large quantities of forged materials such as P20, S50C, etc., significantly shortening customers' mold cycles. It also provides various high-quality domestic and imported mold steels like 2738, 718, NAK80, and to meet customer needs, offers processing services for mold materials such as S50C, P20, 718, 2738, H13, etc.

In the mold base sector, Changhui Company, with over 40 years of deep industry experience, is becoming an "invisible champion" in this niche field through its profound expertise in mold bases.
