More Details
Inner pots are commonly fabricated from aluminum for fast thermal response, light weight, and low cost.
Deep drawing is used to form cup-shaped or cylindrical cavities, typically in 2–3 stages to achieve uniform wall thickness and depth for appliances like rice cookers.
Spinning is applied for prototypes or small batches, providing smooth surfaces and high precision but with lower efficiency.
The interior surface is coated with food-safe non-stick layers such as PTFE or ceramic.
Ventilated metal frames and mounting brackets are produced using stamping and bending.
Punching and blanking operations create arrays of circular, elongated, or shaped holes for ventilation, assembly, and alignment.
Bending operations form flanges and structural edges to enable secure assembly and integration with other components.

FAQs
Q1: Why use deep drawing for inner pots?
Deep drawing efficiently forms deep, axis-symmetric cavities with uniform wall thickness suitable for cooking vessels.
Q2: What are the advantages of spinning?
Spinning produces high-precision, smooth-surfaced components ideal for prototypes or small-batch runs.
Q3: How are vent holes and frames manufactured?
High-speed stamping and bending create precise vent, mounting, and alignment features efficiently.
Q4: Are non-stick coatings applied in prototypes?
Yes. Food-grade coatings such as PTFE or ceramic are applied to replicate final product performance.
