Steel casting refers to the parts formed after steel is melted and poured into a specific casting shape and then cooled and solidified. Cast steel parts usually refers to carbon steel and low alloy steel castings, it has high strength, high toughness and good weld ability. But part of the cast steel parts in the processing and use of the process, sometimes encounter the problem of paint, this time we should be how to solve it?

Precision casting pickling is generally the casting is immersed in an acidic solution, through a chemical reaction to remove a variety of oxidized substances on the surface of the steel and corrosion of the process. Pickling done well, the next passivation process will be much simpler.

Laser cutting process has the advantages of fast cutting speed, good cutting quality and non-contact cutting, which is widely used in various industrial fields, but also has the disadvantages such as large investment. Laser cutting has been popularised to cut and process different materials such as medium and thin plates, which are widely used in various industries such as aerospace, ships and automobiles.

Powder metallurgy is a manufacturing process that produces precision and highly accurate parts by pressing powdered metals and alloys into a rigid die under extreme pressure. The key to the accuracy and success of powder metallurgy is the sintering process that heats parts to bond the powder particle.

Besides creating near-net shapes, powder metallurgy also allows for designing intricate parts, and it offers good dimensional precision. It provides a high degree of part-to-part uniformity, boosting overall product quality.

A chief advantage of powder metallurgy is that it can be considered a green manufacturing technology. As mentioned earlier, it produces little scrap and consumes less energy. The process also creates less air and liquid pollution and less solid waste compared to foundries.

Cleaning up after production in the foundry is crucial, and safety matters need to be kept in mind and prepared for. This includes checking tools, placing castings smoothly, avoiding the use of human body parts in contact with the tools, and placing sand boxes neatly. Only by doing a good job of cleaning can we ensure the quality and productivity of our products.

Forging is a manufacturing process involving the shaping of a metal through hammering, pressing, or rolling. These compressive forces are delivered with a hammer or die. Forging is often categorized according to the temperature at which it is performed—cold, warm, or hot forging.

High pressure die casting (HPDC) is a manufacturing process used to produce metal parts with high precision and excellent surface finish. 

Gray cast iron and ductile iron are both casting parts processing materials, are heavily used in the production of casting parts, but also the current market is the most widely used two casting materials. Many people for gray iron and ductile iron are very strange, that when these two casting materials together, and what will happen to the spark?

Electrolytic polishing and electroplating are two common surface treatment techniques that both involve electrochemical reactions. However, they differ in their effects and treatment processes.

Castings can range in size from a few grams (for example, watch case) to several tones (marine diesel engines), shape complexity from simple (manhole cover) to intricate (6-cylinder engine block) and order size one-off (paper mill crusher) to mass production (automobile pistons).
