At Huahang Precision Manufacturing, we provide end-to-end manufacturing solutions—from precision machining and surface treatment to intelligent inspection—for industries such as medical, aerospace, and automotive. By integrating our core capabilities, we help clients achieve higher reliability, shorter lead times, and better cost control.

1. CNC Precision Machining (96 Multi-Axis Machines)

l Accuracy to ±5μm, eliminating human error for critical applications like medical devices and aerospace components.

l 5-axis simultaneous machining enables complex geometries (e.g., engine blades, medical joints) in one setup, reducing repositioning errors by over 90%.

l Broad material expertise including stainless steel, titanium, and aluminum alloys, with optimized strategies to control thermal deformation.

2. NC Machining & Digital Production

l Rapid changeover (e.g., 30 minutes for automotive parts lines) through G-code programming.

l Integrated equipment data enables tool-life monitoring and dynamic capacity allocation. CAM simulation cuts programming validation from 8 hours to under 1 hour.

l Full-process traceability of key parameters (speed/feed/depth) compliant with ISO9001 standards.

3. MIM (Metal Injection Molding) Process

l Complete in-house workflow: injection molding, debinding, sintering, shaping, and surface finishing (blasting/polishing).

l Material versatility: 316L, 17-4PH, F75, TC4, ideal for high-volume complex small parts.

4. PVD Vacuum Coating & AOI Automated Inspection

l PVD coating technology is an environmentally friendly surface treatment method capable of producing truly micron-level coatings without pollution. It can deposit various single-metal films (such as titanium-aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN, ZrN, CrN, TiAlN), carbide films (TiC, TiCN), and oxide films (TiO, SiO, etc.).

l PVD coating can currently produce film colors including deep yellow, light golden yellow, coffee, bronze, gray, black, light black, and iridescent. By controlling relevant parameters during the coating process, the resulting color can be adjusted. After coating, specialized instruments can be used to inspect and quantify the color to ensure it meets requirements.

l PVD coating exhibits high hardness, high wear resistance (low friction coefficient), excellent corrosion resistance, and chemical stability. The film layer has a longer lifespan and significantly enhances the aesthetic appeal of workpieces.

l AOI systems (HD industrial cameras, laser scanners) ensure defect-free delivery with automated optical inspection.

l Full-process control: From raw material to finished part, reducing supply-chain risks.

l Deep technical expertise: Specialized in complex structures, challenging materials, and micron-level tolerances.

l Quality assurance: Digital production logs provide complete traceability for every component.
