  2. Zinc 5: Balanced combination of strength, ductility, and castability, suitable for a wide range of applications.
  3. Zinc 7: High-strength alloy with good corrosion resistance, often used for parts requiring high mechanical strength.
  1. Magnesium AZ91D: Good balance of strength, ductility, and corrosion resistance, often used for automotive parts and hand tools.
  2. Magnesium AM60B: High-strength alloy with good castability and machinability, often used for automotive and aerospace components.

Sheet Metal Fabrication Finishes

Sheet Metal parts often require surface finishes to enhance their appearance, functionality, and durability. The type of surface finish applied depends on the end application of the part and the desired characteristics.


Durable and corrosion-resistant, anodizing forms a protective coating on the surface of aluminum and titanium components, increasing their corrosion and wear resistance and can be colored for a variety of decorative effects.

Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.

Powder Coating

Powder coating is a surface treatment process that involves applying dry powder to materials such as metal or plastic, then heating to fuse the powder particles and create a smooth, durable coating. The process can be used to apply a variety of colors, textures and finishes to the surface of the material.

Powder Coating


The electroplating process involves several steps, including cleaning and preparing the substrate surface, coating it with a conductive material, immersing the substrate in an electrolyte solution, and applying an electrical current to deposit metal ions onto the substrate surface. The resulting metal layer can be polished, textured or colored to achieve a variety of finishes.

Involves smoothing and shining the surface of a material such as metal, plastic or glass to improve its appearance, texture and reflectivity. The process involves the use of abrasive materials, such as polishing compounds or diamond grit, to remove small imperfections and scratches from the surface of the material, resulting in a smooth and shiny finish.

What is Die Casting?

Pressure casting is a metal casting method that involves using high pressure to inject molten metal into a precisely made mold, where it quickly cools and solidifies to form a part or semi-finished product with certain strength and shape. This method is suitable for producing a large number of identical or similar metal parts, such as automotive components, electronic components, toys, etc.

The pressure casting process typically includes the following steps:

  1. Preparing the furnace to melt the metal.
  2. Pouring the molten metal into the hopper of the pressure casting machine.
  3. Starting the pressure casting machine to inject the metal into the mold at high pressure.
  4. Cooling the metal to allow it to solidify into the desired shape.
  5. Opening the mold to remove the cast part.

Pressure-cast parts are highly valued for their high dimensional accuracy, smooth surface finish, and high production efficiency, making them widely used in various industrial fields.

What is metal casting?

Metal casting is a manufacturing process that involves using high pressure to inject molten metal into a precisely made mold, where it quickly cools and solidifies to form a part or semi-finished product.

What are the types of metal casting?

There are mainly three types of metal casting: sand casting, investment casting, and die casting. Each type has its own specific features and applications.

What is the process of metal casting?

The process of metal casting generally involves designing models, preparing molds, melting metals, pouring them into molds, cooling and solidifying them, and finally taking them out of molds.

What are the precautions for metal casting?

When performing metal casting, it is crucial to control factors such as the temperature of the metal and the speed of pouring, and to follow safety procedures to prevent burns and other accidents.

How is the cost of metal casting calculated?

The cost of metal casting usually includes the costs of raw materials, mold construction, energy consumption, labor, and post-processing. The exact cost will vary depending on factors like the size and complexity of the casting, as well as the volume of production.

What are the advantages and disadvantages of metal casting?

The advantages of metal casting include the ability to produce intricate shapes and precise dimensions, high material utilization rates, and suitability for mass production. However, the disadvantages include higher costs, particularly for mold construction, and the possibility of defects such as gas pores and inclusions in the castings.

How to choose the appropriate casting method?

Choosing the right casting method depends on factors such as the requirements for the casting, production volume, material properties, and budget. For example, for low-volume, complex-shaped parts, investment casting might be preferable due to its relatively lower tooling costs compared to die casting. For high-volume, simple-shaped parts, die casting could be a more cost-effective option.
