Dalian castings, as an important component manufacturing process, have great market demand and development potential. Only by continuously improving production technology, optimizing product quality, and meeting market demand can castings play a more important role in industrial production. The future development of castings requires joint efforts from all parties to promote the progress and innovation of casting technology and promote the healthy development of the casting industry.
It can produce parts with complex shapes, especially suitable for blanks with complex inner cavities, such as radiators. Widely applicable, almost all commonly used industrial metal materials can be used for casting, and the weight of castings can range from a few grams to hundreds of tons. The source of raw materials is abundant and the price is relatively low, such as scrap steel, scrap parts, and chips, which can all be used as raw materials. The shape and size of castings are usually close to the final product, thus reducing the amount of cutting work in the later stage and belonging to the category of few and no cutting work.
What are the details to pay attention to in the production of castings in Dalian?
Material selection: First, it is necessary to choose materials suitable for casting, including metals, alloys, or other materials. The choice of materials will directly affect the quality and performance of the final product.
Design and mold making: The design and mold making of castings are also crucial. Reasonable design can ensure the functionality and quality of the product, while precise mold making can ensure the accuracy and surface quality of the product.
Pouring process: Pouring process is one of the key links in the entire casting process. Attention should be paid to the control of parameters such as pouring temperature, pouring speed, and pouring pressure to ensure that the castings can fully fill the mold and avoid porosity and inclusions.
Cooling and solidification: Special attention should also be paid to the cooling and solidification process of castings. A reasonable cooling and curing process can ensure that the product has a good organizational structure and mechanical properties.
Surface treatment: Surface treatment of castings is also a very important part. Different surface treatment methods can add different functions and appearance effects to products, such as painting, sandblasting, electroplating, etc.
Quality inspection: Strict quality inspection is also required during the production process of castings. By testing the process, we can ensure that the product meets customer requirements and standards, and improve the quality and reliability of the product.
There are many types of castings, including cast iron, cast steel, aluminum alloy castings, copper alloy castings, etc. The quality and performance of castings depend on factors such as the selection of raw materials, process control, and mold design. Therefore, strict quality control is required in the production process of castings to ensure that the products meet the standard requirements.
The application of castings is very extensive, accounting for 40% to 70% in the field of agricultural machinery, and 70% to 80% in the machine tool industry. In addition, in the field of automobile manufacturing, castings such as engine cylinder blocks, cylinder heads, crankshafts, etc. are produced through casting processes. In the petrochemical industry, various valve bodies, pump bodies, etc. are often made of castings. For example, large valve body castings are used to manufacture large valves, which need to withstand certain operating pressures and fluid impacts, and require high sealing and wear resistance.
