What are the specific production requirements for the vacuum extraction process of stainless steel insulated cups?

The vacuum extraction process of stainless steel insulated cups is one of the key steps in manufacturing high-performance insulated cups. Creating a low-pressure environment between the inner and outer walls of the insulated cup through vacuum extraction reduces heat conduction and transmission, thereby enhancing insulation. The following are the general production requirements for the vacuum extraction process of stainless steel insulated cups:

Material Selection: High-quality stainless steel materials, typically food-grade 304 stainless steel, need to be chosen for the manufacturing of insulated cups to ensure product safety and durability.

Inner Liner and Outer Shell Assembly: Insulated cups typically consist of an inner liner and an outer shell. Before the vacuum extraction process, strict assembly of the inner liner and outer shell is necessary to ensure excellent sealing performance.

Vacuum Pump Equipment: Specialized vacuum pump equipment is required for the vacuum extraction process. Ensuring stable pump performance and achieving a sufficiently high vacuum level are essential for effective vacuum extraction.

Vacuum Level Control: During the vacuum extraction process, precise control of the vacuum level is crucial. Both excessively high and low vacuum levels can impact insulation performance. The appropriate vacuum level range needs to be determined based on product specifications and requirements.

Vacuum Sealing: After achieving a sufficient vacuum level, vacuum sealing is required to prevent leakage. The quality of vacuum sealing is crucial for the stability of insulation performance.

Cooling Treatment: Following vacuum extraction, the insulated cup needs to undergo cooling treatment to restore its temperature to normal ambient levels, further enhancing insulation.

Quality Inspection: After completing the vacuum extraction process, quality inspection of the insulated cup is necessary. This includes vacuum level testing, seal integrity checks, and more, to ensure that the product meets design and specification requirements.

Cleaning and Packaging: Finally, through rigorous cleaning and packaging, the stainless steel insulated cup is prepared for shipment in a clean and orderly state, ready for subsequent sales and use.

The vacuum extraction process is a critical step in manufacturing high-quality stainless steel insulated cups. Throughout the entire production process, stringent control of process parameters is essential to ensure quality at each stage, ultimately producing products with outstanding performance and insulation capabilities.
