Zinc die casting is a widely used manufacturing process that ensures precision, durability, and efficiency in producing complex metal components. From sanitary and bathware fittings to automotive and architectural hardware, zinc die casting is the backbone of high-performance industrial applications.
At DST Tech, we specialise in high-quality zinc die casting solutions that meet the evolving needs of modern industries. Let’s dive into the step-by-step process of zinc die casting and understand why it’s the preferred choice for precision manufacturing.
Step-by-Step Process of Zinc Die Casting
1. Mold Design and Tooling
The first and most crucial step in zinc die casting is the design and fabrication of the mold (die). The mold is made from high-grade steel to withstand extreme pressure and temperature. The precision of the mold determines the accuracy of the final product.
DST Tech uses advanced CAD/CAM software to design molds that ensure superior surface finish and dimensional accuracy.
2. Melting and Injection of Zinc
Once the mold is ready, the zinc alloy is melted at high temperatures and injected into the mold under high pressure (usually 1,5000–25,000 psi). This ensures that the molten zinc fills every intricate detail of the mold, producing parts with exceptional strength and consistency.
DST Tech uses state-of-the-art die-casting machines that offer precise control over the injection process, reducing material waste and enhancing product quality.
3. Solidification and Ejection
As soon as the molten zinc enters the mold, it rapidly cools and solidifies into the desired shape. Once the part is set, the mold opens, and the component is ejected using ejector pins.
Our advanced cooling techniques at DST Tech ensure faster production cycles, allowing us to manufacture components with high efficiency and minimal defects.
4. Trimming and Removing Excess Material
After ejection, the component often has excess material or flash that needs to be removed. This is done through trimming, machining, or deburring, ensuring a smooth and polished final product.
Our automated trimming and finishing solutions at DST Tech guarantee consistent quality and precise detailing for every component we manufacture.
5. Surface Finishing and Coating
To enhance corrosion resistance, durability, and aesthetics, the zinc die-cast parts undergo various finishing processes such as:
✔ Electroplating (for chrome, nickel, or other coatings)
✔ Powder coating (for enhanced durability)
✔ Polishing and buffing (for a smooth finish)
At DST Tech, we offer customized surface finishing solutions tailored to different industries like automotive, bathware, and architectural hardware.
6. Quality Inspection and Testing
Before final delivery, every zinc die-cast component undergoes rigorous quality checks to ensure dimensional accuracy, mechanical strength, and surface finish consistency.
At DST Tech, we employ cutting-edge quality control measures, including:
✔ 3D scanning for dimensional accuracy
✔ Tensile strength and hardness testing
✔ Salt spray tests for corrosion resistance
This ensures that every product meets global industry standards before reaching the customer.
