Starting Inquiry

What is Die Casting?

Die casting is a manufacturing process. In it, molten metal is injected into a mold at high pressure. This creates complex and precise metal parts. This method is efficient and low-cost. It makes many high-quality parts. Yonglihao Machinery offers two main types of die casting: hot chamber and cold chamber.

Cold chamber die casting Process

Cold chamber die casting

Cold chamber die casting is suitable for metals with higher melting points, such as aluminum and copper alloys. In this method, the molten metal is melted in a separate furnace and then manually scooped into the die casting chamber. This method is suitable for producing large, robust parts that require higher temperatures.

Materials Used in Die Casting

Die casting uses many metals. Each has unique properties to meet the needs of a specific use. The following metals are supported by Yonglihao Machinery.

Surface Finishes and Treatments

Yonglihao Machinery improves the performance and look of die-cast parts. They do this through many surface treatments and finishes. These treatments ensure that we make products that meet functional needs and have the looks our customers want. Below are some of the common options we offer:

Anodizing: we increase the corrosion resistance of aluminum parts by forming a protective oxide layer on their surface. This treatment also adds color to the metal, increasing its durability and aesthetics.

Powder Coating: We apply dry powder to the part’s surface. Then, we cure it at high temperatures. This creates a strong, even coating. It is more durable than traditional paint. Powder coating provides excellent resistance to corrosion, flaking, and fading.

Brushed Finish: By applying an abrasive brush to the metal surface, we can create a fine line texture. This treatment improves the metal’s look. It gives it a satin-like texture. It also hides fingerprints and small scratches. This makes it both beautiful and practical.

Electroplating: We deposit a thin layer of nickel or chromium on die-cast parts. This layer makes the surface harder and provides great corrosion resistance. It greatly extends the life and performance of the part.

Sandblasting: It blasts fine particles to make a matte finish. This removes imperfections and prepares the surface for more treatments.

Polishing: Friction brightens the metal. It improves its reflectivity. But, it doesn’t affect the part’s size.

Electrolytic Polishing: Removes minute surface burrs by electrochemical means, improving surface finish and corrosion resistance.

Chemical Oxidation: The process gives steel parts a thin coating of magnetic oxides. This coating lowers surface reflectivity and prevents minor corrosion.

Advantages of Custom Die Casting

High Precision and Accuracy: Custom die casting makes parts with tight tolerances. It also makes parts with complex designs. This ensures high precision and consistency. This is critical for parts that require precise dimensions and complex geometries.

Efficiency: Known for its high productivity, die casting is an efficient process for producing large quantities of parts quickly. This method also minimizes waste as excess material can be reused, making it more cost-effective.

Durability: Parts produced through die casting are robust and dimensionally stable. The process creates strong parts. The parts can handle many types of conditions and stresses.

Versatility: Custom die casting is used in many industries. These include automotive, aerospace, electronics, and medical devices. It also supports many materials and alloys. This allows for choosing the best solution for specific needs and performance.
