A, stainless steel shell

Stainless steel casing has the following features:

1. Lightweight and durable, able to withstand high temperature and high pressure.

2. Stainless, corrosion-resistant and heat-resistant, meeting the cooking requirements.

3. The price is relatively high.

Production process:

Stainless steel shell is mainly made of die casting and stamping.

Pressure casting:

1. Make the mold.

2. Fill the mold with filling material and control the pressure to make the part present the required shape.

3. Cooling and curing, and taking out the parts.

Stamping:

1.

2. Put the stainless steel plate in the middle of the mold.

3. Press the stainless steel plate into the required shape with pressure.

Second, the plastic shell.

The plastic shell has the following characteristics:

1. Light weight, easy to carry and low cost.

2. High temperature resistance, but average durability

3. Rich colors and beautiful appearance

Production process:

There are two main methods: injection molding and vacuum injection molding.

Injection molding: after the plastic is melted, it is injected into the mold with high pressure and taken out after the plastic is solidified.

Vacuum injection molding: on the basis of injection molding process, vacuum is introduced into the mold to dissolve bubbles in the melt and reduce pores in the product.
