Die Casting Process

Our die casting process exemplifies precision and efficiency, guaranteeing the highest quality results for your project.

die casting process

Beginning with meticulous mold design and preparation, we utilize advanced technology to create molds tailored to your specifications. Molten aluminum is then injected into the mold under high pressure, ensuring intricate details and consistent part dimensions. Rapid cooling solidifies the aluminum, forming a durable and precise component.

Once the die-casting process is complete, the parts can be further finished using CNC machining. In addition, surface treatments are often employed to ensure tighter critical functional tolerances are adhered to. We provide shot-blasting, texturing, plating, and painting.

We deliver superior parts with fast turnaround times, meeting your project deadlines without compromise. 

Types of Die Casting

Hot Chamber Die Casting

Hot chamber die casting, also known as gooseneck casting, is a method suitable for zinc, magnesium, and other low-melting-point alloys. In this process, the molten metal is contained within a furnace and pumped into the die cavity using a hydraulically operated piston.

The die casting machine’s chamber is connected directly to the die cavity, allowing for a continuous cycle of injection, cooling, and ejection. This process is ideal for high-volume production runs due to its fast cycle times and minimal downtime for metal preparation.

Cold Chamber Die Casting

Cold chamber die casting is preferred for casting metals with high melting points, such as aluminum and copper alloys. This method prevents direct contact between the molten metal and the injection system, reducing wear and prolonging tool life.

Cold chamber die casting offers greater flexibility in casting larger and more complex parts, making it suitable for a wide range of applications across various industries. 

Die Casting Tooling Design

Die casting tooling design is a critical aspect of the manufacturing process, influencing the quality and efficiency of the final product. 

From initial concept to final production, we meticulously consider factors such as part geometry, draft angles, gate placement, and cooling channels to optimize tooling performance.

With a focus on durability and longevity, our tooling designs undergo thorough testing and validation to guarantee consistent and reliable results.
