Investment casting is a metallic developing process in which a wax or plastic design is covered with special clay materials. Once the clay is solidified its inner geometry requires the structure of the casting. The wax is added out after reducing and then melted steel is added into the hole where the wax design was. After solidification of steel within the clay pattern, the steel is damaged out. Investment casting can also be known as missing wax process. This strategy was first used over 550 years back and origins can be tracked back to ancient Egypt and China. Some of the elements made by this techniques are cameras, jewellery, dental accessories, ratchets, equipment elements, gears, turbine blades and other elements of complicated geometry.
• Many sophisticated forms with many cuts can be cast.
• A very soothing surface can be obtained without any parting line.
• Dimensional accuracy is better than in any other type of casting.
• Preplanned shapes can be easily made from certainly unimaginable parts.
• The die-casting technique can be replaced by this technique so that to remove short runs.
• There is no need of draft angle
Disadvantages of Investment casting
• Investment casting is expensive.
• It is mainly restricted to small casting and cause some problems where cores are required.
• It is difficult to build casting having holes smaller than 1.6mm and the having depth less than 1.5 times of diameters.
• The production cycle time of Investment castings is very long as compared to other casting processes.
• Investment casting of high-volume manufacturing seems practically infeasible, because of its high price and long production cycle times.
Investment casting manufacturers
Investment casting manufacturers India have the hi-tech, latest equipment's and machinery to meet the requirements of the latest market trend and are capable of casting almost all types casting materials related to investment casting. Investment casting manufacturers manufacture precision casting material by lost wax process. One of the key points in using investment casting process is that it can produce engineering components and parts that are very close to the final shape of the product i.e. products with excellent finish and accurate dimensions (in microns).
Investment casting manufacturer can make any complex shapes irrespective of material construction. Their production unit has the facilities to provide the fine details like splines, serrations, and holes. They are even capable of reproducing letters and logos accurately. Manufacturers believe in providing materials according to the specification and requirements with the best quality and competitive prices. Every manufacturer works on investment casting as per international standards which define some norms of the production.
Goals of Investment casting manufacturer
According to the market statistics, the use of investment casting is rapidly increasing. Due to large market needs manufacturers has set the goals for their production units to perform better in the market. Some of these are:
• Development of long term business relations with the customers.
• Delivery of end-products in time.
• Superior quality in various standards of investment casting.
• Planning and developing the samples for approval.
• Engineers and technicians are seamlessly trained in order to maintain efficiency and workmanship
