What Is Zinc Die Casting?

Zinc Die Casting is Fun and Good!

Do you want to know about zinc die casting? It is a way to make metal parts. We will tell you all about it!

What is Zinc Die Casting?

Zinc die casting is when we take hot zinc and put it in a steel mold. The zinc gets hard. Then we take out the part.

Here is how it works:

1. We melt zinc alloys like ZAMAK 3 or ZAMAK 5
2. We push the hot zinc into steel dies with a lot of push
3. The zinc gets cold fast
4. We take out the new part

Zinc is good to use because:

• It flows well when hot
• It gets hot at only 385°C
• It does not rust
• It can be used over and over

People who make these parts must follow a rule called ASTM B86. This makes sure all parts are good.

Why Zinc Die Casting is Good

Zinc die casting can make:

• Very thin walls (less than 0.5mm)
• Parts with lots of bumps and holes
• Parts that look smooth and nice

It also helps save money! Here’s why:

• It is 30-50% faster than using aluminum
• The tools last for 1 million or more uses
• You can use old zinc parts to make new ones (95% can be used again)
• Parts are strong but not too heavy
• Parts can block noise from phones and computers
• You can put other metals on top like gold or silver and they stick well

One company that makes says zinc is best for parts that need to be very exact.

Things You Can Make with Zinc Die Casting

You can make lots of cool things with zinc die casting:

Car Parts

• Door handles
• Parts that help cars change speed
• Parts that feel when it’s hot or cold

Phone and Computer Parts

• Cases and covers
• Parts that help connect wires

Plane Parts

• Light parts that don’t rust

Home Things

• Water taps
• Locks
• Pretty parts for your home

Zinc vs Aluminum Casting: Which is Better?

Let’s see how zinc and aluminum are different:

Zinc is faster to make parts with. Aluminum is good for parts that need to be very light.

Some Hard Things About Zinc Die Casting

Zinc die casting is great but it has some problems too:

• It can’t be too hot (not more than 120°C)
• Some shapes are hard to make
• You might need to do more work on the part after it’s made

A company that does custom metal machining can help fix these problems.

New Things in Zinc Die Casting

Zinc die casting is getting better all the time:

• Robots help make parts now
• Companies try not to hurt the earth when they make parts
• New computer programs help make better molds

If you want precision cnc machining, companies that do zinc die casting can help.

Final Thoughts on Zinc Die Casting

Zinc die casting is great for making parts that:

• Need to be very exact
• Need to be made fast
• Need to not cost too much
• Need to be made many times

If you want to make good parts, work with good companies that know about die machining.

ZAMAK alloys like ZAMAK 3 and ZAMAK 5 are the most used metals for zinc die casting. They help make strong parts that last a long time.

Tool longevity is a big plus with zinc die casting. The tools can make over 1 million parts before they wear out!

Automotive components like door handles are often made with zinc die casting because they look nice and work well.

EMI shielding is another good thing about zinc die casting. It helps keep bad signals away from important parts in phones and computers.

So if you need parts that are made just right, think about zinc die casting. It’s fast, good, and not too costly!
