Die casting is not inherently "hard" as a process, but it is complex and requires technical expertise, specialized equipment, and significant upfront investment. Whether it’s considered "hard" depends on the context—designing, setting up, or operating the process. Here’s a breakdown:

Why Die Casting Can Be Considered Hard:

1.Complex Setup: 

Mold Design and Fabrication: Creating the steel molds (dies) is challenging, requiring precision engineering to ensure accurate part geometry and durability. Designing molds involves CAD software, material science knowledge, and accounting for factors like shrinkage or thermal expansion. Mold-making can take weeks and cost $10,000–$100,000+.

Equipment: Die casting uses high-pressure machinery (hot-chamber or cold-chamber systems), which requires skilled setup and maintenance to operate safely and efficiently.

2.Technical Expertise: 

Operators need knowledge of metallurgy, temperature control (e.g., zinc melts at ~420°C), and pressure settings to avoid defects like porosity or incomplete fills.

Troubleshooting issues like flash, warping, or surface imperfections requires experience and process optimization.

3.Material Handling: 

Working with molten metals (e.g., zinc, as you’ve asked about) involves safety risks, such as handling high temperatures and potential exposure to fumes or chemicals used in coatings or lubricants.

4.Initial Costs: 

The high upfront cost of molds and equipment can be a barrier, making die casting "hard" for small-scale or low-budget projects.

Why Die Casting Can Be Considered Easy:

1.Automation and Efficiency: 

Once set up, die casting is highly automated, producing parts quickly (seconds per cycle) with minimal labor. This makes it efficient for high-volume production, like automotive or consumer electronics components.

2.Repeatability:

 After the mold is made and the process is optimized, producing consistent, high-quality parts is straightforward, requiring less manual intervention than processes like machining or forging.

3.Minimal Post-Processing:

 Die-cast parts, especially zinc, often need little finishing (e.g., trimming excess flash), simplifying the workflow compared to subtractive methods.

Conclusion:

Die casting isn’t "hard" once the infrastructure and expertise are in place, but it’s complex and resource-intensive to set up and optimize, particularly for high-quality output. For zinc specifically, it’s relatively easier among die-casting metals due to its lower melting point and good flow properties.
