Changhui Mold Manufacturing Co., Ltd.
—Core Supplier of Precision Car Filter Housing Mold Bases
In the automotive parts manufacturing sector, the precision, sealing performance, and strength of a filter housing directly impact engine reliability and vehicle performance. As a specialized manufacturer of mold bases (mold frames), Changhui leverages advanced equipment, stringent processes, and extensive material reserves to provide the automotive industry with high‑precision, high‑stability filter housing mold base solutions, ensuring that the final product fully meets rigorous industry standards in dimensional accuracy, surface finish, and durability.
Core Strengths: Technical Equipment & Process Assurance
- Professional Team & Core Production CapacityThe company employs over 100 experienced engineers and skilled technicians, equipped with more than 64 precision machining units. Among these, 35 advanced CNC machining centers form the core manufacturing matrix, ensuring efficient, consistent processing from rough to finish machining, and providing reliable assurance for achieving high‑precision tolerances within ±0.01 mm.
- Full‑Process Controlled Precision ManufacturingStrictly following the ISO 9001 quality management system, every step—from cutting, rough milling, chamfering, and deep‑hole drilling to fine surface milling, side finishing, mold frame grinding, and more—is monitored with rigorous inspection checkpoints. We recognize that the mold base is the “skeleton” of the entire mold; its accuracy directly determines the dimensional stability and sealing performance of the final product. Therefore, precision control runs through the entire process, ensuring flatness, parallelism, and hole‑position accuracy fully comply with design specifications.
- Material Reserves & Rapid ResponseOur in‑house raw material warehouse maintains a long‑term stock of large quantities of forged materials such as P20 and S50C, and can also supply high‑quality domestic and imported mold steels like 2738, 718, and NAK80. This ample inventory system significantly reduces lead times for material procurement and pretreatment. Combined with efficient internal production scheduling, it helps customers gain valuable time in project timelines, especially suitable for the fast‑paced response demands of the automotive industry.
- Equipment Capability Covering Diverse NeedsWe are equipped not only with high‑precision machining tools for precision mold bases, but also with large‑scale mold base production equipment, enabling us to undertake the manufacturing of medium‑ to large‑sized filter housing mold bases. This allows us to meet diverse requirements, from small precision components to large housing molds.
Focus Area: Car Filter Housing Mold Bases
Filter housings typically demand high sealing‑surface accuracy, stable assembly dimensions, and good pressure resistance. Mold bases manufactured by Changhui ensure that the mold can produce housings with:
- Dimensional Precision: Critical mounting holes, sealing steps, and other key features can be consistently held within ±0.01 mm tolerance, ensuring part interchangeability and assembly sealing.
- Structural Stability: High‑rigidity plate design and precision guide systems ensure the mold base remains deformation‑ and shift‑free during long‑term injection molding, extending mold service life.
- Fast Delivery: Integrated supply from material to machining shortens mold base manufacturing cycles, helping customers accelerate overall mold delivery.
