Stainless steel cookware is a durable and beautiful cookware. But there are various qualities of stainless steel cookware available in the market. What is the quality of a cookware related to? If you are a brand owner or distributor, you need to have an in-depth understanding of the quality of your products.
This article will introduce the quality-related details of the cookware manufacturing process.

There are two main aspects related to the quality of stainless steel cookware, namely materials and production processes.

Which material is best to choose first?

To ensure the quality of stainless steel pots, you must first choose materials, and first choose high-quality stainless steel materials. High-quality stainless steel pots generally use 304 or 316 stainless steel as raw materials.
Stainless steel is a metal material with excellent corrosion resistance, aesthetics and heat resistance.
It is alloyed with steel, chromium, nickel and other elements. Steel is the main component of stainless steel, chromium is the main anti-corrosion element of stainless steel, and nickel helps improve the corrosion resistance and strength of stainless steel.
The chemical composition of 304 stainless steel contains 18% chromium and 8% nickel, which gives it good oxidation resistance and corrosion resistance.
The chemical composition of 316 stainless steel contains 16%-18% chromium, 10%-14% nickel and 2%-3% molybdenum. Due to the addition of molybdenum, 316 has better corrosion resistance than 304 stainless steel superior.
Generally, 304 is used to make pots and pans, while 316 is used in the food industry, medical industry, watch industry, etc. In terms of price and cost, 304 is more suitable. Unless the customer has special requirements for the product, generally choosing 304 can achieve good quality requirements.

Production process details include those

The manufacturing process of stainless steel pots is a complex and delicate process. This includes cutting, stamping, polishing, welding, surface treatment and quality inspection. Each link needs to be strictly controlled to ensure that the stainless steel pot produced has good corrosion resistance, wear resistance and thermal conductivity. Next, let’s take a look at what aspects we should pay attention to in each link.

1.Cutting

The first choice is to carry out fine cutting according to the plate and avoid the scratched parts of the plate to ensure that the material can be used to its maximum extent. This is an important step in controlling costs.

2. Stamping

The stamping die is processed by wire cutting, so wire cutting marks will be caused on the edge of the embryo body after stamping. Need to be removed after polishing the edges
. The detail that needs attention here is to check whether the embryo body has defects. If there are defects, they need to be picked out to prevent the embryo body from flowing to the next step.

3. Bending

Use a press brake to process the product to the required bending degree. This process will basically not cause defects. However, due to the elasticity of the material itself, there will be an error in the degree of bending between products, which is about 4-5mm. Adjust during boxing to unify the error.

4.Welding

Welding is an indispensable process step in the production of stainless steel pots. Through welding, various components can be connected to form a complete pot product. During the welding process, attention needs to be paid to selecting appropriate welding methods and welding materials to ensure the strength and quality of the welded joints.

5. Polishing

Before polishing, the edge must be ground to remove the line cutting marks on the edge of the product and achieve the required smoothness.
The polishing should be sufficient to smooth out the unevenness and small gaps. If it is not smooth, polish it again.

6. Cleaning and disinfection

After the stainless steel tableware is made, it needs to be cleaned and disinfected. Place the product in a 100-degree sink containing cleaning solution for 10-15 minutes, remove and drain. Cleaning can remove stains and residues on the surface of tableware and keep the tableware hygienic and beautiful. Disinfection is to kill bacteria and viruses on the surface of tableware and ensure food safety.

7. Packaging and quality inspection

The final step is to package and inspect the finished stainless steel pots. Packaging is to protect the pot from damage and facilitate transportation and sale. Quality inspection is to check whether the quality and appearance of the pots meet the requirements and ensure that the products leaving the factory meet the standards. Packaging and quality inspection work require strict implementation of relevant standards and requirements to ensure product quality and safety.

The stainless steel pot production process includes raw material preparation, cutting, stamping, bending, welding, polishing, cleaning and disinfection, packaging and quality inspection. Each link has its specific process requirements and operating steps. Only by strictly following the process can we produce high-quality stainless steel pot products.
