Investment casting has a high cost. The cost of raw materials for investment casting is high.
The cost of special wax materials, high-purity silica sol/ethyl silicate hydrolyzate and other materials is 3-5 times that of ordinary casting. In addition, the process of investment casting is complicated and the production cycle is long. The production cycle of a single piece usually takes 1-2 weeks, which is much higher than sand casting. These factors have led to the high cost of investment casting.
Reasons for high cost
High cost of raw materials: The cost of special wax materials, high-purity silica sol/ethyl silicate hydrolyzate and other materials used in investment casting is high, usually 3-5 times that of ordinary casting.
Complex process: Investment casting requires multiple precision processes such as wax mold making, multi-layer ceramic shell making, dewaxing, high-temperature sintering, metal pouring, etc., with a long production cycle, and a single piece production cycle usually takes 1-2 weeks.
High equipment and technical requirements: Investment casting requires the use of high-precision equipment and advanced technology, which increases the cost.
Impact of high cost
High cost may affect the widespread application of investment casting, especially in large-scale production, other more economical casting methods may be chosen due to cost issues. However, investment casting has obvious advantages in the production of small batches and high-precision parts, and can provide higher dimensional accuracy and surface roughness, which is suitable for the production of castings with complex shapes.
