Aluminum die casting, also known as HPDC, is a versatile manufacturing process that transforms molten aluminum into intricate, high-quality metal parts. This process involves injecting liquid aluminum under high pressure into reusable metal dies (molds). At ABC Vietnam, we collaborate with certified partners in Vietnam to offer top-tier aluminum die casting services. We aim to provide durable, precision-engineered components that meet the demands of industries such as automotive, medical, electronics, and renewable energy. We have established a trusted relationship with customers in the USA, Australia, and Europe. Our operational motto focuses on delivering quality products, maintaining clear communication, and offering competitive prices.
Our Aluminum Die Casting Process
Die casting is one of the best ways to turn raw aluminum into finished goods. This process aims to cut down on material waste and production time, which makes it a smart choice for making large quantities of products without breaking the bank.
Design and Engineering
The process begins with the design and construction of a precise metal die, typically made from hardened steel. Our team of experienced engineers collaborates closely with clients to understand their specific requirements and develop optimized die designs. We utilize advanced CAD/CAM software to ensure precision and manufacturability.
Melting and Injecting
Aluminum, which is light and conducts heat well, gets heated until it melts. Once it’s liquid, the aluminum gets pushed into the die with a lot of force usually between 1,500 and 25,000 psi. This high pressure makes sure the melted aluminum goes into every part of the mold catching even the tiniest details of the design.
Cooling and Solidification
Once the molten aluminum fills the die, the part cools and solidifies. Because aluminum cools quickly, the cycle time for each part is relatively short, allowing for high production rates. As the metal hardens, it shapes itself to match the inside of the mold.
Ejection of the Part
After solidification, the die opens, and with the use of ejector pins, the newly formed part is ejected. The die closes again, and the process repeats for the next part. This high-speed cycle is one of the key advantages of aluminum die casting, allowing for large-scale production with consistent quality.
Post Processing Techniques
After the die casting process, components may require post-processing to enhance their performance and aesthetic qualities. Here are some common techniques:
- Deburring: This process removes sharp edges and excess material. Deburring can be done manually or with machines such as tumbler deburring systems.
- Polishing: To achieve a smooth surface finish, parts can be mechanically polished by hand or using tumbling machines.
Surface Finishing Possibilities
We offer the following surface finishing processes:
- Electrophoretic Deposition (ED) Coating: Provides a uniform, corrosion-resistant finish.
- Chrome Plating: This creates a bright, decorative surface with enhanced wear resistance.
- Nickel Plating: Offers a lustrous finish with excellent corrosion protection.
- Anodizing: This creates a hard, protective oxide layer with customizable colors.
- Chromating: Enhances corrosion resistance and provides a base for paint adhesion.
- Sand Blasting: Achieves a textured surface or prepares the part for further finishing.
- Powder Coating: Creates a durable, protective finish with a wide range of colors and textures.
These finishing techniques ensure that the products meet the quality expectations.
Applications of Die Casted Products
Moreover, the die-casted products we manufacture with our certified partners in Vietnam find their use in a diverse range of fields, including:
