Zinc Die Casting Services for Precision & Durability
About Zinc Die Casting
What Is Zinc Die Casting?
Zinc die casting is a metal forming process in which liquid zinc alloy is injected into a reusable steel mold under high temperature and pressure, and then cooled and solidified into a casting of a specific shape. This process is often used to produce metal parts with complex shapes and high precision, and has high production efficiency and economy.For enterprises, it is an important bridge connecting high quality and high efficiency.
Zinc's unique advantages
Low-Temp Advantage
Zinc alloys melt at relatively low temperatures (~380–420 °C), which reduces furnace energy consumption and tooling wear, leading to lower production costs and a smaller carbon footprint
Superior Fluidity
The molten zinc alloy has excellent fluidity and can fill complex and thin-walled mold structures, achieving high-precision molding of small features and sharp angles.
Recyclability
Zinc is a 100% recyclable metal material; waste can be directly smelted and reused, which is in line with the concept of green manufacturing.
Good Corrosion Resistance
Zinc itself has a sacrificial anode protection function. After alloying, its tolerance to moisture, heat and chemical media is significantly improved, extending the service life of parts.
Superior Fluidity
The material cost is moderate, the mold and equipment life is long, and the production cycle is fast; all in all, the unit cost is advantageous in both small and medium batch and large batch production.
Excellent Surface Finish
The casting surface is smooth and burr-free, which is particularly suitable for subsequent surface treatments such as electroplating, spraying and powder coating, reducing processing steps.
Key Benefits of Zinc Die Casting
High Dimensional Accuracy
The casting dimensional error can be controlled within ±0.05 mm, meeting strict tolerance requirements. The mold has a long repetitive life and high batch consistency.
Superior Surface Finish
The casting surface is smooth and flash-free, which is convenient for direct。electroplating, spraying or powder coating
Excellent Mechanical Properties
Strength and spirit, good impact resistance
Good fatigue resistance, suitable for dynamic wheelchair environment
Design Flexibility
Can integrate multiple functions such as threads, buckles, inserts, etc.
Reduce overall assembly costs and simplify product structure
Cost-Effectiveness
The alloy material is moderately priced, the melting temperature is low, and the energy consumption is less. The molds and equipment are wear-resistant and the amortization cost is low.
Eco-Friendly & Recyclable
100% of waste can be recycled and remelted.In line with green manufacturing and circular economy
Zinc Die Casting Process Overview
Our engineers will fully communicate with you to understand product requirements, use 2D/3D CAD software for modeling, and optimize the design through DFM. Then use advanced equipment such as high-speed CNC, spark machines and wire cutting to accurately process the mold to ensure that every detail meets the requirements of the drawings.
In the medium-temperature furnace, we strictly monitor the melting temperature and chemical composition of the zinc alloy to ensure that the melt is pure and stable. The molten metal is then quickly injected into the mold to effectively fill the complex structure and ensure a very high one-time molding success rate.
The melt is cooled evenly in the mold, and it usually takes only a few seconds to a dozen seconds to form. The mold opens automatically, and the ejector or robotic arm quickly removes the casting, reducing human contact and protecting the product surface intact.
We use a combination of vibration grinding and manual finishing to easily remove burrs and ensure a smooth surface. According to your needs, we provide polishing, electroplating, spraying or powder coating, with a variety of visual and functional effects to choose from.
Each casting will be inspected by CMM three-dimensional coordinates and manual visual inspection for both size and appearance. After passing the inspection, we will sort, buffer and pack according to the customized packaging plan to ensure safe delivery.

FAQs about Zinc Die Casting
Is die-cast zinc safe to use?
Die-cast zinc has a wide range of uses. The surface treatment of zinc is very suitable for a variety of surface treatments, such as painting, powder coating or electroplating. Die-cast zinc is non-toxic and is ideal for items that come into contact with food or beverages. Zinc alloy die castings are safe under normal use. However, during the production process, there are still some safety precautions that need to be paid attention to to ensure safety.
Can zinc be die cast?
Yes, zinc can be used for die casting. Zinc alloys are very suitable for die casting due to their good fluidity and casting properties, as well as their relatively low melting point, especially for manufacturing complex shaped, thin-walled precision parts.
Will die-cast zinc rust?
Die-cast zinc does not usually rust. When zinc is exposed to air, a protective layer of zinc oxide forms on the surface, which prevents further corrosion and rust.
