TOPS is A One-Stop Solution for Zinc Die-Casting
What is Zinc Die Casting?
Zinc die casting is a technique of direct injection of molten zinc alloy into a die or mold to produce close tolerance fine metal parts. This manufacturing process is suitable for making sharply defined components of high strength and good surface finish. Among all the conventional die-casting materials, Zinc has been found to qualify fully for the die-casting process. It has a low melting point, high flowability, and sound mechanical properties.
Types of Zinc Die Casting
Hot Chamber Die Casting
- Here the molten zinc is maintained in a chamber that is directly in contact with the die cavity. A plunger system throws the molten metal into the die.
- It is very effective for metals with low melting points like zinc, it is faster than the other methods of welding.
- Common alloys: Zamak 3, Zamak 5, and Zamak 7 Zinc die casting alloys.
Cold Chamber Die Casting
- The molten zinc is cast into a separate cold chamber, and then it is injected into the die.
- This method is used less in zinc but is useful in alloys that require high melting points or in parts that are thick-walled.
- Common alloys: ZA-8, ZA-12, and ZA-27.
Gravity Die Casting (Permanent Mold Casting)
- In gravity casting, the molten zinc is allowed to flow to the die cavity by force of gravity.
- It is preferred for applications where high strength and density are required, but the part complexity is not very high and the precision as offered in pressure die casting cannot be obtained.
Centrifugal Die Casting
- This technique ejects the molten zinc through the centrifugal force into the mold cavities.
- For the combined sections of rotary parts like pipes and bushings, it is especially valuable in achieving dense uniformity.
Why Choose Zinc Die Casting?
Here are some of the important facts about why you must choose Zinc die-casting services from TOPS Precision:
- Exceptional Precision: Zinc die casting is characterized by high accuracy and ability to produce small features on the component, it is thus suitable for complex components.
- Superior Surface Finish: Zinc die castings exhibit fine, high-quality shining surfaces, which can be used in most cases without further polishing.
- Cost-Effective for High Volume: A high nonappreciation value and a low melting point make Zinc optimum and cheap for mass production cutting down energy costs and cycle times.
- High Durability and Strength: Die-cast alloys of zinc have good strength and are therefore suitable when manufacturing tough parts that are likely to be subjected to much stress.
- Environmentally Friendly: Zinc is easily recyclable and the environmental impact of zinc die-casting percentage is furthermore low therefore it is a better option for manufacturing.
Different Zinc Die Casting Alloys: Properties and Applications
At TOP Precision, we have a variety of zinc die-casting alloys to suit various industrial necessities. Every type of alloy has a characteristic that recommends it for use in a particular application – structural parts that require high strength, coatings that must resist corrosion, and so forth. This table also shows the prominent characteristics of widely employed zinc die-casting alloys, guaranteeing that our customers are given the best possible material for their projects.
Alloy | Properties | Applications |
Zamak 2 | Highest strength, suitable for gravity casting | Replaces bushings; wear-resistant parts |
Zamak 3 | Balanced strength and castability | Standard for general-purpose die-casting |
Zamak 5 | Stronger and harder than Zamak 3 | Widely used in Europe, durable applications |
Zamak 7 | High purity, improved fluidity, and finish | Precision components, aesthetic finishes |
ZA8 | Higher aluminum, hot-chamber compatible | High-strength parts needing hot-chamber casting |
ZA12 | Hard, strong, corrosion-resistant | Automotive and heavy-duty parts |
ZA27 | High aluminum, strong, wear-resistant | High-load parts like gears, automotive components |
Zamak 8 | Stability at high temp/pressure | Parts for high-temp/high-pressure environments |
ACuZinc5 | Very strong, moderate corrosion resistance | Automotive and industrial, high-load capacity |
ZL27 | Good machinability and corrosion resistance | Machined parts like gears |
