What is the Difference Between Precision Investment Casting and Ordinary Casting?
1. What is the difference between precision investment casting and ordinary casting?
The precision investment casting is to pour liquid metal into a casting model with the same shape as the parts. After the casting is cooled, our precision investment casting products can be formed. Casting methods include sand casting, special casting, precision investment casting, V method casting, and precision investment casting belongs to special casting. Parts cast in this way do not require processing, or can be used with a small amount of processing.
Ordinary casting belongs to the scope of forging casting, and die casting is a casting method using pressure casting. The liquid metal is filled into the casting mold at a high speed under high pressure. Let it solidify under pressure. In ordinary casting, many raw materials are applied with external force and deform in a solidified state. In general, precision investment casting and ordinary casting are two different casting methods, but precision investment castings manufacturers have higher requirements and better precision.
2. What is the development prospect of precision investment casting?
The precision investment casting is a special casting method compared to the traditional casting process. The precision investment casting can obtain relatively accurate shape and high casting accuracy. In addition, the product is precise, complex, and close to the shape of the part. It can be used directly without processing or with little processing. The products obtained by precision investment casting are precise and complex, close to the shape of the part, and can be used directly without processing or with little processing. It is a near net shape technology and an excellent process technology in the foundry industry. Its application is very wide. It is not only suitable for casting of various types and alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods.
Even complex, high-temperature resistant, and difficult-to-process castings that are difficult to cast by other casting methods can be cast by precision investment casting. At present, the precision investment casting forming process in the world is developing rapidly and is widely used. From the current situation, the future development trend of this technology is that casting products are getting closer and closer to parts and components. Traditional precision castings are only used as blanks and are no longer adapted to the rapidly changing market.
The complexity and quality of parts and components are getting higher and higher, research and development methods are getting stronger and stronger, professional collaboration is beginning to emerge, and the application of CAD, CAM, and CAE has become the main technology for parts and products development. From the analysis of the current development situation, the application of precision investment casting technology is very wide, and its development prospects in the future are quite broad.
