• Tolerance for investment casting

  2024 / 03 / 28

  Investment Casting Tolerances means the dimension range that can be meet by investment casting. There are a variety of investment casting processes, such as lost wax casting, lost foam casting and solica sol casting. Each casting process has its own casting forming ways and is suitable for different types of products. Tolerances may be affected by a number of factors. Such as die temperature, wax or plastic temperature, injection pressure, mold or shell composition, back up sand, firing temperature, rate of cooling, position of the part on the “tree”, and heat treat temperature all bear directly on tolerances required in the investment casting industry. Althought there is a tolerance standard in investment casting industry, it may still vary from foundry to foundry, as some may be specialized in thin wall small parts, and others could be more professional in larger parts. Also the equipments may also has a certain effect on the casting tolerances.

• Precision casting is also known as investment casting lost wax casting

  Precision casting is also known as investment casting lost wax casting. Compared with other casting methods and parts forming methods, investment casting has the following characteristics: The casting dimension precision is high, the surface roughness value is fine, the casting dimension precision can reach 4-6, the surface roughness can reach 0.4 to 3.2μm, can greatly reduce the machining allowance of the casting, and can realize the no-margin manufacturing, reduce the production cost. To sum up, precision casting has the advantages of small investment scale, large production capacity, low production cost, simple process for complex products and quick investment. Thus, it is in a favorable position in the competition with other technologies and production methods and has a bright future.
