As Ningbo Changfeng Mechanical Factory, established in 1990, we specialize in delivering high-quality precision investment casting services for steel and stainless steel CNC machined parts, leveraging our decades of expertise to meet global industrial demands. With an annual export value of US$10 million to US$50 million and a strong presence in markets including North America, South America, Eastern Europe, Southeast Asia, and beyond, we offer reliable solutions that ensure accuracy and durability for complex components. Our services focus on providing cost-effective manufacturing with a commitment to precision, helping clients reduce production time and enhance product performance. We pride ourselves on our extensive experience and customer-centric approach, making us a trusted partner for industries worldwide. At Ningbo Changfeng, we combine advanced technology with skilled craftsmanship to deliver parts that meet stringent specifications and exceed expectations.
Our precision investment casting services involve a meticulous process that starts with creating a wax pattern, coating it in ceramic, and then casting molten steel or stainless steel to produce near-net-shape parts. This is followed by CNC machining to achieve exact dimensions and surface finishes. Key features include:
- Material versatility: We work exclusively with high-grade steel and stainless steel, offering options like 304, 316, and carbon steel variants for superior corrosion resistance and strength.
- Advanced CNC machining: Post-casting machining ensures tight tolerances and complex geometries, with capabilities for milling, turning, and finishing.
- Custom design support: From prototype to mass production, we handle custom specifications, including unique shapes and sizes, to fit specific applications.
- Quality assurance: Each part undergoes rigorous inspection for dimensional accuracy and surface integrity, minimizing defects and ensuring consistency.
For detailed technical specifications, refer to the table below:
| Parameter | Specification |
| Material Options | Steel (e.g., AISI 1045), Stainless Steel (e.g., 304, 316) |
| Tolerance Range | ±0.1mm standard, customizable for tighter needs |
| Typical Size Capabilities | Up to 500mm in length/width, custom sizes available |
| Surface Finish | Ra 0.8-3.2μm, options for polishing or coating |
| Production Volume | Prototype to high-volume orders (e.g., 1000+ units) |
These services provide significant benefits for clients, such as reduced material waste through precise casting, lower overall costs due to efficient manufacturing, and faster time-to-market for critical components. By integrating investment casting with CNC machining, we eliminate secondary operations, enhancing part integrity for demanding environments like automotive engines or aerospace assemblies.
Backed by our 30+ years of manufacturing experience and a global footprint spanning North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europe, and other regions, Ningbo Changfeng Mechanical Factory offers unparalleled reliability and expertise. Our consistent export performance, with annual values between US$10 million and US$50 million, underscores our capacity to handle diverse international orders with timely delivery and consistent quality.
