A basic introduction to Investment Casting

My country began to apply investment casting to industrial production in the 1950s and 1960s. Since then, this advanced casting process has been greatly developed and has been widely used in aviation, automobiles, machine tools, ships, internal combustion engines, gas turbines, telecommunication equipment, weapons, medical equipment and cutting tools, and other manufacturing industries. The production of gold, silver, platinum, and other metal jewelry and other metal arts and crafts, and other decorations often adopts the investment casting industry. It is required that the casting blank not only has good reproducibility for artistic modeling, but also requires easy sand cleaning after casting, and the surface of the casting is required, quality is smooth. For this reason, the casting material must not only have a certain mechanical strength but also have good casting formability, collapsibility, and crack resistance. At present, investment casting in the prior art mainly adopts multi-layer shell casting, and there is also a small amount of investment casting plaster casting. A new related product that has also emerged in recent years is Investment Casting Die Casting with Zinc/Aluminum. So what is investment casting? What kind of characteristics does it have and what parts does it apply to? Let's take a look.

What is Investment Casting?

Investment Casting is an industrial process used to create metal parts whose details are difficult or impossible to achieve with other casting methods. Investment Casting uses a model that is destroyed during the process to invest in the finished product. The process is the oldest casting process used by mankind, investment casting is one of the most basic metal forming techniques, it is a multi-step process that provides fine details at a reasonable cost.

Features of Investment Casting

Investment Casting has many features. The first is that there are many types of casting, especially high-temperature alloy castings. Production by investment casting process can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual knife lines after machining. Secondly, investment castings have high dimensional accuracy. And the surface finish of the investment mold is relatively high. The shell is made of high temperature-resistant special binder and refractory paint made of refractory material, which is painted and hung on the investment mold, and the inner surface of the cavity that is in direct contact with the molten metal has high smoothness. Finally, it can save a lot of machine tool equipment and processing time, and greatly save metal raw materials, and there is no limit to the production batch, which can be produced from single piece to batch. These characteristics make it widely used in industry. In recent years, the newly developed Investment Casting Die Casting with Zinc/Aluminum has also been widely used because it is becoming more and more environmentally friendly.

Applicable Parts for Investment Casting

Investment Casting is mainly used for casting various batches of cast steel and small complex precision castings of high melting point alloys, especially suitable for casting artworks and precision mechanical parts. Use batches of high melting point alloy precision castings, mass-produced small parts with complex shapes that are difficult to machine. Such as blades, impellers, guides, guide wheels and automobiles, tractors, pneumatic tools, small parts on machine tools, and handicrafts such as steam turbines, gas turbines, water turbine engines, etc.
