The general process of casting production is to make molds, melt raw materials, pour, cool, clean, and finishing to finish products. Many casting processes are derived from this process. This answer briefly summarizes this content. Kindly search for other content on the website to fully understand it.

The general process for making sand casting molds is to make two upper and lower sandboxes, make a casting pattern, mix sand and binder, fill it into the sandbox with the pattern and vibrate it, take out the pattern, put it in the sand core and close the box. The method or whether to remove the pattern needs to be determined according to the casting process. For example, the pattern of investment casting is taken out through high-temperature evaporation, while the pattern of lost foam casting does not need to be taken out. We will introduce it in more detail below.

Our foundry is equipped to offer a diverse range of high-quality casting processes. We specialize in sand casting, which allows us to create a wide variety of metal parts with complex geometries. Whether it's for small-scale prototypes or large-volume production runs, our sand casting process ensures consistent results.

We also excel in die casting. This process is ideal for producing precision parts with smooth surfaces and tight tolerances. Using state-of-the-art die-casting machines, we can handle different types of metals, particularly aluminum and zinc alloys, for applications in the automotive, electronics, and consumer goods industries.

In addition, we provide investment casting services. This is the go-to process when creating intricate and detailed components. Our investment casting team has extensive experience in producing parts for the aerospace, jewelry, and medical device industries, where precision and surface finish are of utmost importance. With our comprehensive range of casting processes, we can meet the unique needs of every customer, regardless of the project's size or complexity.

Castings and forgings are significantly different in production, materials, workpiece shape, internal structure, mechanical properties, applications, etc. Here only a relatively simple comparison is made between them. Kindly contact us if you have a workpiece and you are not sure which process is more suitable for production.

To ensure dimensional accuracy, proper mold design is essential. The mold should be designed with allowances for shrinkage, as most metals shrink as they cool and solidify. Using high-quality mold materials that can withstand the heat and pressure of the casting process without deforming is also crucial. In die-casting, the precision of the die itself plays a major role. Regular calibration and maintenance of the casting equipment, such as pouring systems and injection units in die-casting, are necessary to ensure consistent and accurate operation. Additionally, post-casting machining operations can be used to further refine the dimensions of the part to the required tolerances.

Aluminum is extremely popular. It has a low density, good corrosion resistance, and high thermal conductivity, making it suitable for a wide range of applications, from aircraft parts to cookware. Iron, especially cast iron, is another commonly cast metal. It has excellent castability and high compressive strength and is often used in engine blocks, pipes, and machinery parts. Copper and its alloys, such as brass and bronze, are also widely cast. They offer good electrical and thermal conductivity as well as attractive aesthetic properties, which is why they are used in electrical components, decorative items, and musical instruments.
