Gray iron castings use lost foam and resin sand casting processes, equipped with large gas tempering kilns, manual aging, and quenching to release internal stress, thereby improving the accuracy of the castings after processing. During the finishing process of the bed body, the machine tool experiences heating of the spindle due to prolonged cutting, which causes thermal deformation and affects the ultimate processing accuracy. For high-precision machine tools and large machine tools, processing errors caused by thermal deformation account for about 40-70%. Since thermal deformation can only be improved and cannot be eliminated, under the condition of a fixed machine tool, it is generally only possible to stabilize the machine tool temperature by controlling the cutting conditions, thus avoiding the impact of temperature changes on processing accuracy.

Gray cast iron and ductile cast iron are two of the most commonly used materials in the manufacturing industry. While they may look similar, there are significant differences between the two. In this article, we will explore the difference of gray cast iron and ductile cast iron.

A stainless steel motorcycle engine cylinder block is a vital component of the engine that houses the cylinders where the combustion process takes place. It is made from stainless steel, a durable and corrosion-resistant metal known for its strength and heat resistance.

From the perspective of various defects of stainless steel, as well as the causes of these defects, there are many factors that can affect the defects of castings, and the process control of each link will affect the final casting quality. Combined with the casting defects encountered in the past production practice, steel casting manufacturers can strictly control the quality from the following three aspects.

After auditing 37 foundries across North America, I've identified three critical gaps in traditional gray iron casting processes - all of which Supreme's advanced foundry solutions address through cutting-edge metallurgical control.

The method of formulating the model, modeling and core making of large-scale cast steel: the solid wood type is used as the solid wood type of the operating side frame. The wood surface layer is combined with steel, wood and soil to achieve the forming of the inner core box of the frame, meet the shape requirements, and save wood and time. Both the medium sand and the core material in the casting process are very important. In order to make the quality of the frame meet the requirements, the resin is used as the mold and core sand. It can not only ensure the quality requirements of sand mold and sand core, but also improve productivity.
