Stainless steel, a crucial material in daily kitchenware, is widely utilized for its durability and corrosion resistance. The Chinagama factory possesses advanced processing techniques for stainless steel and is eager to share the manufacturing process with prospective buyers. This knowledge can facilitate a smoother OEM & ODM production, providing a better understanding of product characteristics.
We'll illustrate the production process using the example of a stainless steel oil pot body. However, before delving into the specifics, let's first explore the material properties of stainless steel.
Stainless Steel Material Properties
Advantages:
1. Corrosion Resistance: Stainless steel withstands corrosion, maintaining stability in appearance and performance even in humid environments.
2. High Strength: Stainless steel's high strength allows for the manufacturing of various structures and components, providing excellent resistance to compression, tension, and bending.
3. Ease of Processing: Stainless steel's plasticity and weldability facilitate diverse processing and shaping, creating products in various shapes and sizes.
4. Hygienic Safety: Stainless steel is non-toxic, does not release harmful substances, and complies with hygiene standards, making it widely used in food processing and medical equipment.
5. High-Temperature Resistance: Stainless steel performs well in high-temperature environments without deformation or loss of performance.
Disadvantages:
1. Cost: Stainless steel manufacturing costs are relatively high, resulting in higher product prices, which may not be suitable for low-cost projects.
2. Susceptible to Scratching: Despite its hardness, stainless steel can still be scratched by sharp objects, affecting its appearance and requiring regular maintenance.
3. Heavy Weight: Stainless steel has a high density, making it relatively heavy and limiting its use in certain applications.
4. Poor Thermal Conductivity: Stainless steel has relatively poor thermal conductivity, which may be less suitable for applications requiring rapid heat dissipation.
304 Stainless Steel
Among the various types of stainless steel, kitchenware factories commonly use 304 stainless steel, also known as 18-8 stainless steel, with 18-20% Cr and 8-10.5% Ni. Its high nickel-chromium alloy content imparts excellent corrosion resistance, making it widely applied in the food industry.
Production Process of Stainless Steel
Raw Material Preparation:
Stainless steel sheets are the primary raw material. Unrolling these sheets provides the basic material for oil cruet production.
Shaping:
Through processes like stamping and cutting, stainless steel sheets are transformed into specific shapes and sizes, determining the overall dimensions and structure of the product. Modern machines and automation ensure efficient and precise operations.
Forming:
The stainless steel sheets undergo deep drawing and pressing to shape them into vessels with round sides and bottoms, using advanced machinery.
Heat Treatment:
The formed bodies undergo heat treatment to enhance strength, hardness, and deformation resistance. This typically involves heating to specific temperatures followed by rapid cooling to modify the crystalline structure.
Inner Surface Treatment:
The inner surface undergoes precise grinding to remove burrs and defects, ensuring a smooth and uniform interior. This not only improves product quality but also reduces friction resistance during use, making the kettle easier to clean.
Polishing:
A polishing step follows, providing a smooth and shiny surface, further reducing roughness and enhancing the product's visual appeal.
Coloring (if required):
Depending on the product specifications, coloring may be applied to perfect and meet consumer demands.
By understanding this comprehensive production process, kitchenware procurement professionals can make informed decisions and collaborate effectively with manufacturers like Chinagama for high-quality stainless steel products.
