SEHY provides custom aluminum alloy castings with precision machining for industrial equipment and mechanical components. Combining the design flexibility of metal casting with the accuracy of CNC machining, these components can be manufactured to meet specific structural, dimensional, and assembly requirements.
Available in selected aluminum alloys such as A356, A380, and ADC12, the castings can be produced using suitable casting processes according to part geometry, material requirements, and production volume. Secondary machining, surface finishing, and inspection can also be arranged based on customer drawings and specifications.
From prototype development to repeat production orders, SEHY supports customized aluminum casting projects for manufacturers, equipment suppliers, and industrial component distributors.

Aluminum alloy casting is widely used to manufacture components with complex shapes, integrated structures, and varying wall sections. Compared with machining an entire component from solid aluminum material, casting can produce a near-net-shape blank, helping reduce material waste and the amount of subsequent machining required.
For components that require accurate mounting interfaces, threaded holes, bearing bores, or sealing surfaces, CNC machining provides the additional precision needed for assembly and functional performance.
SEHY combines aluminum casting and secondary machining to produce customized components according to customer requirements. The casting method, alloy grade, machining allowance, and finishing process are evaluated according to the part design and intended application.
Aluminum alloys offer a favorable strength-to-weight ratio and good thermal conductivity, making them suitable for many weight-sensitive mechanical and industrial applications. Depending on the selected alloy, casting process, and heat treatment, different mechanical and physical properties can be achieved.
Casting allows manufacturers to produce component geometries that may be difficult or costly to create entirely through conventional machining. Ribs, bosses, curved profiles, and integrated structural features can be incorporated into the casting design to meet functional and assembly requirements.
After casting, critical surfaces can undergo CNC milling, turning, drilling, and tapping. These operations help control mounting dimensions, bore sizes, threaded connections, and other functional features according to the approved technical drawing.
Different projects require different aluminum alloy properties and casting methods. SEHY offers selected alloy options, including A356, A380, and ADC12, with the manufacturing route determined by component geometry, mechanical requirements, and expected production volume.
Depending on the selected alloy and application, surface treatment options may include polishing, painting, powder coating, and anodizing. The appropriate finish is selected according to appearance, environmental exposure, and functional requirements.
Material selection directly affects the casting process, mechanical properties, machinability, and final component performance.
SEHY offers the following aluminum alloy options for customized casting projects:
Aluminum Alloy | Typical Characteristics | Common Casting Applications |
|---|---|---|
A356 | Good castability, mechanical properties, and heat-treatment potential | Structural castings, machinery components, and housings |
A380 | Good fluidity, castability, and general-purpose mechanical properties | Die-cast housings, brackets, and industrial components |
ADC12 | Good filling characteristics for relatively complex die-cast geometries | Electronic housings, equipment enclosures, and mechanical parts |
The appropriate alloy should be selected according to the component's working conditions, strength requirements, dimensional design, and production method. A356 is commonly associated with sand or permanent mold casting, while A380 and ADC12 are widely used in high-pressure die casting.
Exact alloy designations and applicable material standards should be confirmed before production.
The manufacturing process is planned around the component drawing and required finished dimensions. Depending on the project, the production workflow may include:
1. Drawing Review & Design Evaluation
Review 2D drawings, 3D models, or physical samples to understand the component structure, critical dimensions, material requirements, and machining needs.
2. Casting Process Selection
Evaluate the component geometry, alloy, production quantity, and dimensional requirements to determine a suitable casting method, such as sand casting or die casting.
3. Tooling & Mold Development
Prepare the required casting patterns or molds according to the approved component design. The tooling structure is considered together with casting shrinkage, draft angles, wall thickness, and machining allowance.
4. Aluminum Alloy Casting
Melt and pour the selected aluminum alloy using the agreed casting process to produce the required component blanks.
5. Secondary CNC Machining
Machine critical surfaces, mounting holes, bores, threaded connections, and other features that require closer dimensional control.
6. Surface Finishing & Quality Inspection
Complete the specified finishing operations and inspect the finished parts against the agreed technical drawings and quality requirements.

Every custom casting project starts with a different set of requirements. Some components need complex internal structures, while others require precise mounting interfaces, specific surface finishes, or particular mechanical properties.
SEHY works with customers to evaluate casting and machining requirements before production. Whether you need a new component developed from a 3D model or an existing casting reproduced from a physical sample, customized manufacturing solutions can be discussed according to your project.
To help us evaluate your aluminum casting project, please provide:
2D engineering drawings or 3D CAD files
Required aluminum alloy grade and material specifications
Component dimensions and estimated weight
Preferred casting process, if already specified
Critical machining dimensions and tolerance requirements
Surface treatment and inspection requirements
Prototype quantity or expected annual production volume

Common options listed for SEHY's custom casting service include A356, A380, and ADC12. Each alloy has different casting characteristics and mechanical properties. The appropriate material depends on the component design and intended application.
Sand casting uses a prepared sand mold and is suitable for various component sizes, complex geometries, and flexible production volumes. Die casting forces molten metal into a reusable metal mold under pressure, making it suitable for repeat production of components with relatively consistent dimensions and detailed shapes.
