Investment casting involves the following sequence of operations.
The drawing is provided by the customer, based on which we evaluate the feasibility of manufacturing the component through the investment casting process. Once the design is approved, we proceed with the production of aluminum or mild steel (MS) tooling.
Once the drawing is provided by the customer, a 3D model is prepared incorporating dimensional and shrinkage allowances, which is then shared with the customer for approval
Once the design is approved, we proceed with the production of aluminum or mild steel (MS) tooling / Die.
Once the die is received, wax is injected to produce patterns as per the order. These patterns are then cleaned and repaired, if necessary, before proceeding to the assembly stage.
Assembly of wax patterns is carried out according to the technical data sheet, forming a complete pattern tree for further processing
The wax assembly is successively coated with high-grade ceramic slurry and refractory materials to develop a durable ceramic shell.
Dewaxing is carried out using either a steam autoclave or a flash fire furnace to eliminate the wax from the ceramic shell.
The ceramic mold is preheated in a shell backing furnace at approximately 1000°C (1832°F). Molten metal, heated to around 1500°C to 1600°C—depending on the metal type—is then poured into the mold cavity using a ladle.
Once the cast shells have cooled, ceramic removal is performed through mechanical vibration. Castings are separated from the runner system using cut-off machines, followed by gate grinding with abrasive tools and finishing operations using ceramic pneumatic tools for a clean and precise surface.
Heat treatment is carried out in metal to enhance the mechanical properties of metal alloys—such as corrosion resistance, abrasion resistance, and hardness—through controlled heating, holding, and cooling processes
The dimensions of the casting are measured using a variety of calibrated instruments to ensure that the produced component conforms to the customer-provided drawing.
The castings are then transferred to the machining stage, where they are machined as per customer requirements using various setups, fixtures, jigs, and tools.
Final inspection is carried out as per the machining drawing provided by the customer to ensure all specifications are met.
The final dispatch of goods is conducted in accordance with the dispatch notes received from the customer.
We Manufacture INVESTMENT CASTING know as Lost Wax / Micro Fusion / Feinguss Casting in Ferrous & Non-Ferrous Cast Metals.
