Investment Casting of Stainless Steel Frying Pans

Stainless steel frying pan, sometimes called stainless steel skillet, is the common cookware used in kitchen during our daily life. Frying pans have flat bottoms, flared sides, a shallow depth, and no lids. These features make them the perfect choice for shallow frying, flipping food, stirring, high-heat searing, or grilling meat at high temperatures.

Usually, frying pans are made of cast iron and cast stainless steel for their different qualities and properties. Cast iron pans are used because although they do not conduct heat very evenly, they do retain it quite well, making them useful for searing meats and vegetables. Nowadays, most frying pans are now made from cast stainless steel. Stainless steel frying pans are the best for browning ingredients-and since they’re usually uncoated, unlike nonstick varieties, they are more durable and resistant to slip-ups in the kitchen. Most importantly, stainless steel is a non-reactive metal-unlike cast iron-and won’t introduce a “tinny” flavor profile into a dish that’s highly acidic. For a thin profile of stainless steel frying pans, you can better control temperatures compared to cast iron ones.

Investment casting is a good manufacturing process to make stainless steel frying pans, due to its precision, simplicity, and versatility.

In the process of investment casting stainless steel frying pans, a wax pattern is designed around which to create a mold. The wax pattern has the same dimensions as the frying pans needed. Once the wax pattern is ready, it is then coated in a ceramic slurry that’s made to withstand high heat. From there, the internal pattern is burned out of the hardened ceramic slurry mold. If this process is done incorrectly, the mold will be useless as it will create defects in the parts.

The molten stainless steel is then poured into the ceramic mold, sometimes at temperatures exceeding 3000 degrees Celsius, and allowed to cool and harden. While some molds are gravity-fed, others must be moved or vented to allow for thinner or more complex designs.

When the stainless steel is solidified and hardened, the ceramic mold will be removed, and the sprue gate is cut to achieve net shape parts. Finally, shot blast the frying pans and inspect them for delivery.
