Crafting a Perfect Pressure Cooker Body: A Step-by-Step Guide

Step 1: Deep Drawing

The process begins with deep drawing, where a flat sheet of metal is transformed into a hollow shape. This is achieved by using a punch to force the metal into a die, gradually forming the basic cylindrical shape of the pressure cooker body.

Step 2: Deep Drawing-Thinning

Following the initial deep drawing, the thinning process takes place. This step involves further drawing out the metal to ensure uniform thickness throughout the pressure cooker body. This is crucial for maintaining the structural integrity and consistent performance of the cooker.

Step 3: Cutting and Shrinking

After achieving the desired thickness, the excess metal is trimmed off through cutting. Shrinking is then employed to refine the shape and dimensions of the pressure cooker body, ensuring it meets the precise specifications required.

Step 4: Outer Polishing

The outer surface of the pressure cooker body is polished to achieve a smooth and attractive finish. This not only enhances the aesthetic appeal but also helps in removing any surface imperfections that may have occurred during the previous steps.

Step 5: Inner Sanding

Inner sanding is performed to smooth out the interior surface of the pressure cooker. This step is essential for ensuring that the inner surface is free from rough edges and imperfections, which could affect the cooker's performance and safety.

Step 6: Handle Hole Punching

Next, precise holes are punched into the pressure cooker body for the handles. This step requires accuracy to ensure that the handles are securely attached and properly aligned, providing a safe and ergonomic grip for the user.

Step 7: Handle Riveting

Finally, the handles are riveted onto the pressure cooker body. This involves securely fastening the handles using rivets, ensuring they are firmly attached and capable of withstanding the pressure and heat during cooking.

Each of these steps is critical in the production of a high-quality pressure cooker body, combining precision engineering with skilled craftsmanship to create a durable and reliable kitchen appliance.
