Precision Small Casting Solutions for OEM Applications
Small castings are widely used in industries requiring lightweight, high-precision, and geometrically complex metal components. At HDC, we manufacture custom small castings using investment casting and die casting processes, supporting a wide range of materials, tolerances, and finishing requirements.
From miniature mechanical parts and pump components to hardware fittings and electronic housings, we help OEM customers produce reliable small metal components with consistent quality and scalable production.
Our engineering team supports projects from prototyping to mass production, including tooling development, CNC machining, surface finishing, heat treatment, inspection, and assembly.
Our Casting Process
Moulage d'investissement
When it comes to complex geometries and material flexibility, investment casting is our recommended choice for small castings.
- ±0.1 mm as cast tolerance
- 1.5 mm min wall thickness
- Multiple materials compatible
Moulage sous pression
Die casting is valued for its high efficiency in producing components with rich details, especially for small parts that are hard to CNC.
- Over 10, 000 pieces daily production
- 1 mm min wall thickness
- High consistency across batches

Process Selection Guide
Choosing the right casting process depends on part geometry, material requirements, production volume, surface finish expectations, and cost targets.
At HDC, we help OEM customers select the most suitable manufacturing method for small metal components based on their application and production goals.
Choose Investment Casting When:
- Your part has complex geometries
- Multiple alloy options are required
- Mechanical strength is important
- You need stainless steel or steel components
- Production volume is relatively low or medium
- Fine details and smooth surfaces are needed
Choose Die Casting When:
- High-volume production is required
- Lightweight aluminum or zinc parts are preferred
- Thin walls and tight repeatability are important
- Unit cost optimization is critical
- Fast production cycles are needed

FAQ
What is considered a small casting?
Small castings typically refer to compact metal components with relatively low weight and dimensions, often requiring high precision and fine details.
Which process is better for small castings, investment casting or die casting?
Investment casting is better for complex geometries and multiple alloy options, while die casting is more suitable for high-volume aluminum or zinc parts.
What tolerances can you achieve?
Tolerance capability depends on material, geometry, and process. CNC machining can be added for tighter tolerances.
Can you manufacture custom OEM small castings?
Yes. We manufacture fully custom small castings according to drawings, samples, or specifications.
Do you provide machining and finishing?
Yes. We offer complete secondary operations including CNC machining, polishing, coating, plating, and assembly.
