Durability
Zinc is a durable material that can withstand wear and tear, making it an ideal choice for door handles. Zinc door handles are resistant to rust, corrosion, and fading, ensuring that they last for many years.
Design flexibility
Zinc is a versatile material that can be molded into a variety of shapes and designs, allowing for a wide range of customization options. This means that zinc door handles can be tailored to match the style and aesthetic of any home or building.
Easy maintenance
Zinc door handles are easy to maintain and clean. They can be wiped down with a damp cloth or cleaned with mild soap and water, making them a practical and low-maintenance option for door hardware.
Affordability
Zinc is a cost-effective material that is less expensive than other metals such as brass or stainless steel. This makes zinc door handles an affordable option for homeowners and builders looking for high-quality door hardware at a reasonable price.
Environmental friendliness
Zinc is a recyclable material that can be reused to create new products, making it an eco-friendly choice for door handles. Zinc door handles can be recycled at the end of their useful life, reducing waste and environmental impact.
Zinc Door Handle Production Process
Material preparation
Generally, the melting point of zinc alloy is between 419-420°C. During the heating process, other elements may need to be added to improve the properties of the alloy, such as magnesium or silicon, etc.
Mold design and preheating
The mold is made of steel and needs to be specially designed according to the product design. Before die casting, the mold need preheat to a certain temperature. That’s to ensure rapid solidification and reduce defects when the metal is injected.
Mold material selection
Tool steel or special alloy steel is usually used to ensure the wear resistance and heat resistance of the mold.
Mold structure design
This including pouring system, cooling system, and ejector structure. The design of the pouring system should ensure that the molten metal can evenly fill the mold, avoiding defects such as porosity and shrinkage. The cooling system is used to control the temperature of the mold, ensuring rapid solidification of the molten metal in the mold and reducing thermal stress.
Pin design
Pin is used to eject molded parts, and its shape and size should be optimized according to the specific structure of the door handle to ensure the quality of the workpiece during the ejection process.
Preheating process
Preheating is an essential step in the zinc alloy die-casting process. It aims to increase the mold temperature, reduce the temperature difference between the molten metal and the mold. Thereby reducing thermal stress and improving the quality of castings.
Injection
The molten zinc alloy is injected into the mold cavity at high pressure and speed. This process usually complete within a few seconds, for example, the cycle time of the hot chamber die casting process can be as short as a few seconds.
Cooling and solidification
In the mold cavity, the zinc alloy cools rapidly and solidifies. To ensure the integrity and quality of the casting, the mold needs to apply a certain clamping force to prevent deformation during the injection process.
The Effect of Cooling Rate on Solidification Structure
The cooling rate has a significant impact on the solidification structure of zinc alloys. We can see as the cooling rate increases, the solidification structure of the alloy will refine, so improving its mechanical properties.
Process control of cooling and solidification
In the manufacturing process of zinc alloy door handles, precise control of cooling and solidification is required.
Ake out
When the casting is completely solidified, the mold opens and the ejection mechanism ejects the product from the mold. This step requires good control of the thickness of the die casting to avoid quality problems caused by uneven thickness.
Post-processing
The zinc alloy door handle after die casting may need further surface treatment or machining to meet the accuracy and appearance requirements of the final product.
Electroplate
Electroplating is a crucial step in the post-treatment of zinc alloy door handles.
Spray painting and powder coating
Spray painting and powder coating are common surface treatment methods used to give zinc alloy door handles rich colors and good weather resistance.
Polishing and Grinding
Polishing and grinding are key steps in improving the surface smoothness and aesthetics of zinc alloy door handles.
Assembly and packaging
The post-treatment of zinc alloy door handles also includes assembly and packaging steps.
》Strong mechanical properties and abrasion resistance at normal temperature.
》The stability required for melting is not high, melting at 385°C, it can be easily die-casted into shape.
》The proportion is large.
》Powerful casting function, capable of die-casting various complex shapes and thin-walled precise and accurate devices according to different needs. The surface of the casting is smooth and layered.
》Able to perform easy surface treatment such as electroplating, spraying, painting and other operations.
》There is no need for iron absorption during melting and die-casting operations, and sticking is not easy to appear.
