FAQ
Zinc Die Casting Frequently Asked Questions
What is zinc die casting?
Zinc die casting is a high-pressure casting process used to produce small and complex metal components with fine features, smooth surfaces and repeatable dimensions.
What are Zamak alloys?
Zamak alloys are zinc-based die casting materials commonly used for precision components, hardware, connector parts and appearance-focused parts.
What is the difference between Zamak 3 and Zamak 5?
Zamak 3 is often selected for general zinc die casting with good dimensional stability. Zamak 5 is selected when higher mechanical strength is required.
Why choose zinc instead of aluminum?
Zinc is often preferred for smaller parts requiring fine details, thin features, smooth surfaces and stable repeat production. Aluminum is usually preferred for lightweight larger housings and thermal components.
Can zinc die cast parts be plated?
Yes. Zinc die cast parts are often selected for plating, polishing, painting and other appearance or functional finishing routes.
What tolerance can zinc die casting achieve?
Tolerance depends on geometry, tool design, feature location and post-processing requirements. FSD reviews dimensional requirements before quotation.
Can CNC machining be added?
Yes. CNC post-machining can be added for critical holes, threads, datum surfaces and assembly interfaces when required.
What files are required?
Please provide 2D drawings, 3D CAD files, Zamak or material requirements, quantity, surface finish expectations, tolerance requirements and application information.
