This service is designed to meet the specific needs of our customers, ensuring that every component conforms to the exact specifications required for optimal performance.


In addition to offering high-quality aluminum die casting services, we prioritize casting design reviews in close collaboration with our customers before mold production begins. This proactive approach ensures that the molds are precisely designed and developed, improving the overall casting process and reducing the likelihood of defects.


Furthermore, we provide a comprehensive range of customized services to address the unique needs of our clients. These services include polishing, grinding, hand finishing, drilling, tapping, and CNC machining (encompassing both turning and milling). Our experienced team is proficient in applying various surface treatments and coatings, which enhance the strength, appearance, and performance of the castings, adding significant value for our customers.

Once aluminum die castings are produced, they typically undergo a range of CNC machining processes to meet the final specifications, including precise dimensional accuracy, surface finish, and enhanced functionality. These machining steps are essential to ensure that the castings comply with both customer requirements and industry standards, particularly when the parts are intended for high-precision applications. CNC machining is employed for a variety of operations, such as precision processing, surface treatment, threading, hole drilling, marking, and more. The most common CNC machining operations used in post-casting include:

Precision Machining

After the casting process, parts may have rough surfaces or irregular shapes that do not meet the required specifications. CNC milling, turning, or cutting operations are employed to remove excess material and refine these imperfections. This process ensures that the casting meets the exact geometric requirements, including precise dimensions, smooth edges, and accurate angles. CNC machines can handle complex geometries, making it possible to produce parts with tight tolerances that would be difficult to achieve manually.

Surface Treatment

Surface treatment is essential to improve both the aesthetic and functional properties of the casting. CNC machining is used to perform surface finishing operations such as polishing, grinding, and deburring.

Polishing: CNC polishing removes fine surface imperfections, giving the casting a smooth, glossy finish. This is particularly important for parts that require a high-quality visual appearance, such as automotive or consumer electronics components.

Grinding: CNC grinding is used to achieve fine surface finishes and tight dimensional tolerances. It is particularly effective for parts requiring smooth surfaces or specific geometries, such as flat surfaces or holes.

Deburring: CNC deburring removes sharp edges and burrs that may have formed during the casting process, ensuring the parts are safe to handle and fit for assembly.

Drilling

Drilling operations are crucial when the castings need to be assembled with other components. CNC drilling is used to create precise holes for bolts, fasteners, or pins that will be used in the assembly of larger products. This operation is highly precise, and CNC machines can be programmed to drill multiple sizes and depths, ensuring consistent hole quality across many parts. Additionally, CNC drilling can be combined with other operations like tapping or counterboring, depending on the specific requirements.

Threading

When aluminum die castings need to accept screws, bolts, or other fasteners, CNC threading is used to create internal or external threads. CNC lathes or mills can precisely cut threads to ensure the correct fit for fasteners. This process is crucial for parts that require secure mechanical connections, such as automotive components, industrial machinery, or electrical housings. CNC threading is highly accurate, ensuring that the threads are uniform and capable of withstanding stress without stripping or breaking.

Engraving or Marking

Engraving and marking are often necessary to add identifying features to the casting, such as logos, serial numbers, part numbers, or manufacturing dates. CNC engraving machines are used to create precise text, patterns, and logos on the surface of the casting. This process is especially important for traceability, branding, or compliance with industry standards. For example, serial numbers may be engraved to ensure that each part can be individually identified and tracked throughout its lifecycle.

Surface Treatment

Surface Treatment Services

Once the aluminum die castings are completed, additional surface treatments play a crucial role in improving both the functional properties and aesthetics of the parts. Beyond the precision achieved through CNC machining, processes such as powder coating and anodizing are commonly employed to ensure the aluminum castings meet both performance and visual standards.

Surface Treatment


Powder Coating: Powder coating is a widely used surface treatment for aluminum die castings, particularly when enhanced durability and a visually appealing finish are required. The process begins with thorough surface preparation, including cleaning and degreasing, to remove any contaminants such as oil, dirt, or oxidation. The part is then sprayed with a fine powder made of resins and pigments, which adheres to the surface electrostatically. The coated part is subsequently baked in an oven at high temperatures to cure the powder, creating a hard, durable, and smooth finish. This treatment significantly improves the wear resistance of the casting, making it more resistant to scratching, fading, and weathering. Additionally, powder coating allows for a wide variety of color options, enhancing the aesthetic quality of the parts.


Anodizing: Since aluminum is highly susceptible to oxidation when exposed to air, anodizing is a commonly used process to enhance the material’s corrosion resistance and surface durability. Anodizing is an electrochemical process that transforms the aluminum surface into a durable oxide layer, which is thicker and more corrosion-resistant than the natural oxide layer that forms on untreated aluminum. The anodized layer not only protects the casting from corrosion but also improves its resistance to wear and abrasion. The anodized surface can be dyed to achieve various colors, adding aesthetic value to the part. In addition to improving performance, anodizing provides a sleek, glossy appearance, making it a popular choice for applications in harsh environments such as marine components, automotive parts, and industrial equipment.


Additional Surface Treatments: Other surface treatments may also be used depending on the application requirements, including:

  • Electroplating: In some cases, aluminum die castings are electroplated with metals like zinc, chrome, or nickel to enhance their appearance and provide additional corrosion resistance.
  • Polishing and Buffing: These processes involve mechanical abrasion to smooth the surface and create a high-gloss finish. They are commonly used for decorative components or products requiring a shiny, mirror-like surface.
  • Laser Etching or Marking: For traceability or branding purposes, laser etching can be used to create precise markings, such as serial numbers, logos, or text, directly on the surface of the aluminum casting.


Each of these surface treatments can be tailored to specific performance, durability, and aesthetic requirements, ensuring that the final product meets both functional needs and customer expectations.
