Zamak 3 is the most common alloy used in the industry. There are other alloys like Zamak 2, Zamak 5, and ZA-8 available to fit a variety of applications.
What is the most common alloy used in Zinc die casting?
What is the estimated tool life of a die-cast tool for Zinc?
We estimate approximately 1MM shots before a tool requires replacement. This can vary depending on the complexity of the tool and casting.
What finishes can be applied to a Zinc die casting?
Zinc is one of the most flexible cast alloys to finish. Options include plating (decorative & functional), painting (wet & powder) & E-coat.
Can Zinc castings be anodized?
Anodizing on Zinc alloys is not recommended as it provides an inconsistent surface finish.
How do I reduce porosity in my Zinc die castings?
Work with the Cast Products engineering team at the time of product development. We use the latest Flow Simulation software (Magmasoft) to develop the most efficient material flow within the tool.
Can you weld Zinc die castings?
No. Zinc alloys cannot be welded as the heat destroys the casting.
Do Zinc alloys provide conductivity and shielding properties?
Yes. Zinc is highly conductive and often used in applications requiring EMI or RF shielding.
How is flash removed from a Zinc casting?
Flash can be removed from a Zinc casting through thermal deburr, vibratory deburr, and shot blasting.
Does Zinc die cast parts require a trimming operation?
In most cases, secondary trim operations can be avoided. At Cast Products, we focus on flash free casting which eliminates the need for trimming.
How thin of a wall can you allow in a Zinc casting?
The flow properties of the common cast alloys provide the ability to cast thin walls. Thickness is dependent on part design so please contact our Zinc casting Engineering team to discuss.
What is the melting temperature of Zamak alloy?
The melting point of Zamak Zinc Alloys is 787 degrees Fahrenheit.
Are Zinc alloys environmentally friendly?
Yes. Zinc is a naturally occurring element and is easily recyclable. Because of its low melting temperature, Zinc processing uses less energy than other die-cast alloys.
How do I choose the right Zinc alloy for my application?

How long have Cast Products been in business?
We were founded in 1966 and continue to provide top quality Zinc die casting and tooling.
Do Cast Products recycle?
Yes. At Cast Products, we recycle our gates, runners, and overflows.
What size of parts can Cast Products produce?
Our part range is from a few grams to over a pound.
Is there a volume requirement to quote?
Cast Products is a high-volume die caster with volumes from several thousand to millions of parts annually.
Do you build your own tools?
Yes. We have an internal tool shop where most of our tools are built.
Can you support transfer tools?
This is discussed on a case-by-case basis. A transfer will be dependent on tool size, type, and condition. Please contact us to review.
What secondary operations can CPI provide?
We can provide drill, tap, and mechanical assembly.
Can you provide prototypes?
CPI has options for prototypes depending on our customer’s requirements. We can provide 3D printed plastic prototypes, spin, and investment components, or build single cavity tools for low volume and functional review.
What alloys do Cast Products offer?
We provide a variety of Zinc Alloys, including Zamak 2, Zamak 3, Zamak 5, ZA-8
Does Cast Products ship outside the USA?
We currently ship to Mexico, Canada, and the USA.
