What is Encapsulated Base?

Encapsulated base is a type of base in cookware. It is composed of two layers of stainless steel sandwiched between a layer of metal.

What is the Function of Encapsulated Base?

The first is aesthetics. Cookware with this type of base gives it a heavy, solid feel. This feeling will make the end consumer feel that the product is durable, thereby creating a desire to buy it.

The second is compatibility. Cookware with this kind of bottom can be used not only on gas stoves, but also on induction cooktops. Gas stoves and induction cooktops are necessities in modern kitchens, and they have given rise to a variety of cooking methods. Using cookware that is compatible with both gas and induction cooktops means saving money and effort, while also meeting different cooking needs.

Is Encapsulated Base Common?

In actual manufacturing, high-end pots are generally made of aluminum, and the thickness of the aluminum sheets ranges from 2.0mm to 8.0mm; aluminum sheets with a thickness of 4.0mm and below are generally brazed and heated at high temperatures to melt the aluminum sheets into a suitable state. , then cool, the pot body, aluminum sheet, and bottom sheet will stick together.

If the aluminum sheet exceeds 4.0MM, a priming machine must be used for priming; otherwise the aluminum flake is too thick and will not melt easily, affecting the quality of the pot bottom. Generally, priming uses an instantaneous pressure of 1500 tons to 2500 tons to remove the aluminum from the bottom of the pot. The sheet and the bottom sheet are tightly bonded together.

In the mid-range pot market, consumers want the pot to be thick and cheap; therefore, iron sheets are clamped at the bottom of the pot during production; the density of iron sheets is about three times that of aluminum sheets, and iron sheets of the same thickness are heavier than aluminum sheets. 3 times, and the price of iron is much cheaper than that of aluminum.

Is Stainless Steel Cookware with Aluminum Encapsulated Base Safe?

Before answering this question, we need to understand what is aluminum encapsulated base. As mentioned earlier, aluminum encapsulated base is a base that two layers of stainless steel sandwich a layer of aluminum.Aluminum has excellent thermal conductivity, but is soft and easily scratched. Stainless steel acts as a protective layer, is durable, can withstand high temperatures and corrosion, and does not react with food. Therefore, it is very safe to use.

Other Types of Encapsulated Base

Factories also usually manufacture copper encapsulated base, which is composed of two layers of stainless steel sandwiched between a layer of copper. Copper has strong thermal conductivity. Stainless steel serves as the outer layer, providing it with protection. However, the copper encapsulated base is not compatible with induction cookers, and it needs to be polished to maintain its appearance. Therefore, consider copper encapsulated base cookware carefully before purchasing.

In addition to copper encapsulated base and aluminum encapsulated base, there is also stainless steel encapsulated base. It replaces the aluminum/copper in the middle with iron. Stainless steel encapsulated base cookware will be heavier, cheaper and popular in the mid-range cookware market.

What Type of Encapsulated Base Should I Purchase?

This question needs to be combined with target market analysis. If the target market prefers mid-range cookware, we recommend that you purchase stainless steel encapsulated base cookware from the factory. If your target market prefers high-end cookware, it is recommended that you purchase aluminum encapsulated base cookware. Budget is also an important dimension to consider. Decide the quantity to purchase based on your budget.

Encapsulated base cookware, featuring two layers of stainless steel surrounding a central layer of metal, combines aesthetic appeal and practical compatibility for gas stoves and induction cooktops. In high-end pots, aluminum undergoes a meticulous manufacturing process, while mid-range options may utilize cost-effective iron sheets. Stainless steel cookware with an aluminum encapsulated base is considered safe due to the protective properties of stainless steel. Copper and stainless steel encapsulated bases offer alternative choices, with copper requiring careful consideration for its incompatibility with induction cookers. The decision on the type of encapsulated base to purchase should align with a targeted market analysis, balancing factors such as weight, cost, and durability, with budget considerations influencing the quantity to acquire.
