The casting process for producing cast steel parts is advantageous due to its wide range of material applications, allowing for the manufacture of various precision cast steel parts, as well as castings from aluminum alloys, ferroalloys, and copper alloys. For brittle alloys with poor plasticity, such as ordinary cast iron, casting is the only viable forming process. Cast steel parts possess a certain dimensional accuracy, generally exceeding that of ordinary forgings and welded parts. Furthermore, the production cost of cast steel parts is low, offering good overall economic performance, and its energy and material consumption and production costs are unmatched by other metal forming methods. Cast steel has a high melting point…
The development of silica sol precision casting in China is relatively recent. The manufacturing process requires high precision, necessitating a deeper understanding of the process in both theory and practice, and continuous improvement of fundamental professional knowledge. Silica sol precision casting enriches practical experience, streamlining the entire precision casting production process and producing higher-quality products. During the filling process, the foam model needs to be liquefied and decomposed, generating many small-molecule gases and foam ash. These substances…
China's foundry industry has always been an important, fundamental, and irreplaceable sector of the national economy, boasting advantages such as relatively low costs and wide process adaptability. my country is a major foundry nation, ranking first in the world in terms of annual casting output, number of employees, and enterprises. With the increasing trend of economic globalization and the continuous development of the market economy, the demand for and reliance on various standards in casting-related processes, production, and management are growing. In my country, many problems remain to be solved in achieving large-scale production of aluminum alloy castings and meeting the requirements of automotive lightweighting: First, automotive requirements for aluminum castings are shifting towards thinner walls, more complex shapes…
316 and 304 stainless steel castings are widely used in applications requiring corrosion resistance. They are used in all fields, from construction and medical to food processing equipment. Stainless steel castings are ideal for use in environments with high hygiene requirements. Firstly, they do not react with corrosive acids. Secondly, surgical instruments and tableware made of stainless steel are easy to clean and sterilize. Another reason for using stainless steel is that it does not require powder coating to resist corrosion and can maintain its aesthetic appeal. Of course, although they are called stainless steel castings, wear and corrosion are only a matter of time…
Stainless steel casting is a casting process with little or no cutting. It is an excellent technology in the casting industry with a wide range of applications, suitable for casting various types and alloys. Simply put, the stainless steel casting process uses fusible materials to create a fusible model, which is then coated with several layers of a special refractory coating. After melting and drying to form a monolithic shell, the model is melted away from the shell using hot water or steam. Stainless steel casting offers high dimensional accuracy. The investment casting process is complex, meaning many factors directly affect the dimensional accuracy of the castings. The shell is heated…
Stainless steel is a familiar material to many, and it offers numerous advantages compared to other materials. In fact, stainless steel castings have very high requirements in both design and mold making. Although some products may seem easy to cast, they still have strict requirements regarding processability. So, what are the process requirements for stainless steel castings? Below is an introduction. 1. The parting surface must be flat. The parting surface of stainless steel castings must be flat to minimize the presence of burrs and flash. Some factories, in order to reduce the workload of casting, will…
With years of experience in various projects, Haijin Precision Casting understands and complies with international material specifications, including but not limited to ASTM, AISI, ANSI, AS, BS, DIN, EN, JIS, KS, ISO, etc.
The Necessity of Quality Inspection for Large and Medium-Sized Stainless Steel Castings: In recent years, the rapid development of the casting industry has led to the problem of inconsistent product quality. However, if we manufacture a product and sell it immediately without considering its quality, the product's quality is insufficient, and customers will feel uneasy using it. This principle also applies to large and medium-sized stainless steel castings. It's not necessary to investigate the reasons for defects in large and medium-sized stainless steel castings or complete the process during manufacturing; the goal is to continuously improve product quality to enhance overall usability. Of course, this involves continuously improving the specific characteristics of the product based on its actual usability…
This standard is based on the casting surface roughness comparison sample block specified in (GB/T 15056-2017) to inspect the casting surface roughness plating, and serves as a reference for casting process and selection of casting surface roughness.
