What should be noted in the standard operation of vacuuming process for stainless steel insulated cups?

Stainless steel insulated cups are a common type of drink container, and their excellent insulation performance often comes from the vacuuming process. Here are the standard operating procedures and related precautions for vacuuming stainless steel insulated cups.

1. Preparation: Clean the stainless steel insulated cup and ensure that the sealing ring and all components are intact.

2. Heating treatment: Place the stainless steel insulated cup in a preheating chamber for heating treatment, and it is generally recommended to heat it to around 60℃.

3. Vacuuming: Put the heated stainless steel insulated cup into the vacuum pump and connect it to the vacuum pump and the cup body through a pipeline. Open the air exhaust valve to start vacuuming until the desired vacuum degree is reached.

4. Inflation: After completing the vacuuming process, inflation needs to be carried out quickly. This step can be performed by directly introducing gas or first injecting inert gas and then introducing air.

5. Quality check: Check the appearance of the stainless steel insulated cup after vacuuming to ensure that the sealing and vacuum degree meet the requirements.

It should be noted that during the vacuuming process of stainless steel insulated cups, the following points should be paid attention to:

1. The cleanliness and dryness of the environment need to be ensured during the air extraction process to avoid the influence of pollution and moisture on the vacuum degree.

2. The temperature needs to be controlled during the heating process to prevent damage or deformation to the stainless steel insulated cup itself.

3. After inflation, it is necessary to conduct testing to ensure that the vacuum degree and sealing meet the requirements before use.

4. Pay attention to safety issues, such as the vacuum pump cannot run continuously for a long time and equipment needs to be checked regularly to ensure normal operation.

In summary, the vacuuming process for stainless steel insulated cups is an important production process that needs to strictly follow the standard operating procedures and pay attention to relevant operation specifications and safety issues. Only in this way can the stainless steel insulated cup have excellent insulation performance and reliable quality for use.
