Machinery Parts, as an important part of mechanical equipment, has many advantages and wide applications. First of all, mechanical parts are usually made of high-strength materials with wear resistance and corrosion resistance, and can operate stably for a long time in various harsh environments. Secondly, the manufacturing process and design of mechanical parts have been precisely optimized to achieve high precision and stability, ensuring efficient operation and long-term reliability of mechanical equipment.
Mechanical parts are widely used in various mechanical equipment and industrial fields. In the manufacturing industry, mechanical parts are used to manufacture various machine tools, production lines and automation equipment, including gears, bearings, transmission devices, etc. In the automotive industry, mechanical parts are used to manufacture engines, transmission systems, braking systems and chassis parts, ensuring the performance and safety of the vehicle. In the aerospace field, mechanical parts are of critical importance for manufacturing aerospace components such as aircraft, missiles and satellites.

Ningbo Hansheng Machinery Parts Co., Ltd. (Ningbo Yifei Machinery Parts Co., Ltd.) is a Machinery Casting Parts manufacturer and supplier based in Ningbo, China. Founded in 2003, we operate a 5,000 m² factory with ISO 9001:2000 quality assurance. Our core capability is producing custom ferrous and non-ferrous castings—via investment casting, sand casting, die casting, and forging—for machinery applications ranging from pump housings and valve bodies to gearbox components and excavator bucket teeth.
We serve OEMs and engineering firms in construction hardware, automotive, engineering machinery, medical equipment, printing, textile, conveying systems, and marine hardware. Most of our output is exported to the United States, United Kingdom, Germany, France, and Spain.
We supply cast and machined parts in four primary process families. Each is selected based on part geometry, production volume, alloy, and required mechanical properties.
| Process | Typical Part Weight | Alloy Examples | Common Applications |
|---|---|---|---|
| Investment Casting (lost wax) | 0.25 – 100 kg | 304, 316, 17-4PH, carbon steel, alloy steel | Valve bodies, pump impellers, medical components, aerospace brackets |
| Sand Casting | 0.5 kg – several tons | Gray iron, ductile iron, carbon steel, stainless steel | Machine bases, gearboxes, pump housings, heavy equipment frames |
| Die Casting | Up to ~10 kg | Aluminum, zinc, magnesium alloys | Automotive housings, electrical enclosures, precision brackets |
| Forging | 0.1 – 50 kg | Carbon steel, alloy steel, stainless steel, brass, aluminum | Gears, shafts, connecting rods, trencher teeth |
We cast and machine parts from a broad range of alloys. Our standard material list includes:
Dimensional tolerances can reach ±0.05 mm for investment castings, with surface finishes down to Ra 6.3 μm. For sand castings, tolerances are adjusted per part size and design complexity. We accept drawings in PDF, AutoCAD, SolidWorks, and ProE formats.
Our quality system follows ISO 9001:2008. Each production lot undergoes strict material inspection and dimensional control. We maintain traceability from raw material to finished part. Key in-house equipment includes wax injection machines, CNC machining centers, and heat treatment furnaces. We also coordinate secondary operations such as polishing, anodizing, galvanizing, chrome plating, and powder coating.
For projects requiring mechanical testing, we can provide tensile, hardness, and impact reports. Pressure-containing components receive hydrostatic or pneumatic testing per your specification.
Our machinery casting parts are designed for:
We treat each part as a custom project. Our engineers review the working point, material requirements, production volume, and target cost to recommend the most suitable process. For example, investment casting is preferred for complex geometries with thin walls and fine surface finish; sand casting is chosen for large, heavy parts; die casting suits high-volume aluminum or zinc components; forging is specified when maximum strength and grain flow are required.
We support OEM orders and can produce parts from your drawing, sample, or design concept. For multi-component assemblies, we can supply fully machined and finished parts ready for direct assembly.
To prepare a firm quotation and process recommendation, we need the following project data:
Send your inquiry to master@nbyifei.com or call +86-574-88067800. We typically respond within 24 hours with a preliminary process recommendation and pricing.
Q: What is the typical lead time for a custom machinery casting part?
A: Lead time depends on complexity and quantity. For investment casting with existing tooling, we can ship samples in 3–5 weeks. Sand casting and forging lead times are similar. Tooling fabrication adds 2–4 weeks. We confirm the schedule in our quotation.
Q: Can you handle both small prototype runs and high-volume production?
A: Yes. We support low-volume prototypes (10–100 pieces) for validation and scale up to annual volumes of 10,000–100,000 pieces. Our flexible production setup allows us to adjust batch sizes efficiently.
Q: What quality documentation do you provide with shipments?
A: Standard documentation includes material test certificates, dimensional inspection reports, and a certificate of conformance. Additional NDT reports (MPI, X-ray, pressure test) can be arranged per your specification.
Q: Do you offer machining and surface finishing in-house?
A: We perform CNC machining, heat treatment, and polishing in our factory. For specialized coatings such as anodizing, galvanizing, or powder coating, we coordinate with approved partner shops under our quality control.
Q: How do you ensure dimensional accuracy for complex castings?
A: We use precision wax injection dies for investment casting and CNC-machined patterns for sand casting. First-article inspection is performed on every new tool. During production, we conduct in-process dimensional checks and final 100% inspection on critical features.
Our portfolio also includes NEXT: Investment Casting Process for Machined Parts By Customized Casting Service, NEXT: Investment Casting Stainless Steel Machine Part, Custom Machine Part by Investment Casting Process Factory for applications with different operating ranges, interfaces or integration requirements.
