Pressure Die Casting

Custom Casting Solutions

Custom die casting services offer manufacturers the ability to produce complex, high-quality metal parts tailored to specific requirements. These services typically focus on two main types of die casting: hot chamber and cold chamber casting, both capable of producing parts with intricate geometries. Custom die casting is particularly advantageous for creating durable components from materials such as aluminum, brass, and zinc, often at lower costs and with faster turnaround times compared to other manufacturing methods.

Key benefits of custom die casting services include:

Custom die casting services are ideal for industries requiring complex, precision-engineered components, such as automotive, aerospace, and electronics, where high-quality, cost-effective production is essential.

Die casting is a widely used manufacturing process that injects molten metal into molds to create precise, high-quality components for various industries. With methods like high-pressure and low-pressure casting, diverse applications in sectors such as automotive and aerospace, and the use of metals like aluminum, zinc, and magnesium, die casting offers tailored solutions for complex geometries, material properties, and production needs, making it a versatile choice for custom and large-scale manufacturing.

High-Pressure vs Low-Pressure Casting

High-pressure and low-pressure die casting are two distinct methods used in manufacturing metal parts, each with unique characteristics:

High-pressure die casting uses pressures of 700 to 2500 bar, allowing for rapid production of thin-walled parts with excellent surface finish and dimensional accuracy. It's ideal for high-volume production of complex, detailed components, particularly in soft alloys like aluminum and zinc.

Low-pressure die casting operates at 0.7 to 1.5 bar, resulting in slower, more controlled filling. This method is better suited for larger parts (up to 150 kg) and produces components with higher strength and less porosity. It's more cost-effective for lower volume production and allows for heat treatment of parts.

While high-pressure die casting offers faster cycle times and smoother surfaces, low-pressure die casting provides better material properties and is more suitable for thicker-walled parts. The choice between these methods depends on factors such as part size, complexity, production volume, and required material properties.

Tooling Design for Complex Geometries

Tooling design for complex geometries in die casting requires careful consideration of part features and mold construction. Multi-slide tooling, which uses four perpendicular slides, enables the production of intricate and accurate castings, particularly for small zinc components. For more complex parts, designers must account for undercuts, which can prevent die separation and cast ejection. Solutions include designing parting lines around undercuts or using dies with multiple components beyond just the core and cavity. Advanced computer-aided design (CAD) software with mold flow simulations helps optimize tooling for complex geometries, allowing designers to analyze fluid movement and correct errors before production. This approach ensures that intricate details are accurately reproduced in the final product while maintaining efficient manufacturing processes.

Manufacturing Process Comparison

Die casting and CNC squeeze casting are two distinct manufacturing processes, each with unique advantages and applications. Here's a comparison of their key characteristics:

Die casting excels in high-volume production of complex parts with excellent surface finish, while CNC squeeze casting offers superior strength and is better suited for producing high-strength components with specific requirements. The choice between these methods depends on factors such as production volume, part complexity, and desired material properties.
