Lost Wax Investment Casting is Used in Medical and Pharmaceutical Industries
Lost wax investment casting is a process of making simple to complex objects from various metals such as gold, silver, brass or bronze by casting the original model or pattern. It is one of the oldest known metal-forming techniques, dating back 6,000 years, but it is still widely used in the production of jewelry, dentistry and art. Its industrial form and investment casting are common methods of making precision metal parts in engineering and manufacturing.
Ⅰ. The lost wax investment casting is used in the medical industry and pharmaceutical industry
One of the applications of lost wax investment casting in medical industry is to manufacture medical implants. Castings must meet strictly standards and be manufactured in accordance with regulatory specifications. Products produced by lost wax investment casting have excellent density and mechanical properties. Several proliferation processes are used to ensure the longevity of the implant and eliminate porosity and other fatigue factors. Other products in the medical industry include surgical tools such as tweezers. The lost wax investment casting is the preferred method for manufacturing medical devices because the parts do not require mechanical processing and are easy to sterilize.
As in the medical industry, products in the pharmaceutical industry must be able to undergo a sterilization process. Parts and instruments are made of high quality stainless steel, with corrosion resistance, high temperature resistance, meet the health requirements. One of the main features of lost wax casting China of pharmaceutical tools, and the reason for its use, is that the parts have a smooth surface that does not easily collect bacteria.
Ⅱ. The lost wax investment casting is used in power industry and tool industry
The power industry increasingly needs to improve its methods and use durable components. Components must withstand wear, erosion, cavitation, fatigue and corrosion at extremely high temperatures. To manufacture components that meet the harsh conditions of the electric power industry, manufacturers of lost wax components use cobalt, nickel, and stainless steel to meet the needs of electric power industry applications. Parts need to be finely machined and coated using a variety of processes to avoid wear problems.
The lost wax investment casting for the tool industry uses steel alloys with excellent tensile strength, hardness and elasticity, which make tool parts durable and able to withstand impact and increased mechanical loads. The lost wax investment casting was chosen for its ability to reconstruct complex geometry without the need for a post-casting process, which is further supported by the dimensional accuracy of the final product.
