Deep analysis of knowledge in the stainless steel insulated cup industry (III): Implementation standards and quality control
In the stainless steel insulated cup industry, implementing standards and quality control are key links to ensure product quality and safety. As a professional manufacturer of stainless steel insulated cups, we deeply understand the importance of strictly implementing national standards and strengthening quality control for the development of our enterprise. Today, let's delve into the execution standards and quality control of stainless steel insulated cups together.

1, Execution standards
As a metal material and product that comes into contact with food, the implementation standards for stainless steel insulated cups are crucial. At present, the implementation standards for stainless steel insulated cups in China mainly include the following aspects:

Material standard: The body of the stainless steel insulated cup (including the inner liner and outer shell) shall comply with the standard of GB 4806.9 "National Food Safety Standard for Metal Materials and Products in Contact with Food". This standard puts forward strict requirements for the raw materials, sensory, physical and chemical indicators of stainless steel materials, ensuring the safety of metal materials and products used in food contact. At the same time, with the release and implementation of new standards, stricter requirements have been put forward for impurity element content and alloy element migration limits in metal substrates and metal coatings.
Product standards: The product standards for stainless steel insulated cups mainly include GB/T 29606-2013 "Stainless Steel Vacuum Cups" and GB/T 40355-2021 "Stainless Steel Vacuum Insulated Containers". These two standards specify in detail the material requirements, capacity, insulation effect, impact resistance, sealing and other key quality indicators of stainless steel vacuum cups (including bottles and pots). Among them, GB/T 40355-2021 further expands the scope of stainless steel vacuum containers based on GB/T 29606-2013, and adds requirements for cold insulation efficiency and rating standards for thermal insulation efficiency.
Accessory standard: The lid of a stainless steel insulated cup usually contains accessories such as plastic and sealing rings. These accessories must comply with the standards of GB 4806.7 "National Food Safety Standard for Plastic Materials and Products in Contact with Food" and GB 4806.11 "National Food Safety Standard for Rubber Materials and Products in Contact with Food". These standards impose strict requirements on the raw materials, sensory, physical and chemical indicators of plastic and rubber materials, ensuring the safety of plastic materials and products used in food contact and rubber materials and products.
2, Quality control
In the production process of stainless steel insulated cups, quality control is a key link to ensure product quality and safety. Our factory has taken the following measures in terms of quality control:

Raw material procurement: We strictly purchase raw materials in accordance with the requirements of the execution standards, ensuring that all raw materials meet national standards and food safety requirements. At the same time, we have established long-term and stable cooperative relationships with multiple high-quality suppliers to ensure stable supply and reliable quality of raw materials.
Production process control: In the production process, we adopt advanced production equipment and process technology to ensure the accuracy and consistency of the products. At the same time, we have established a strict production process control system to monitor and detect every production link in real time, promptly discovering and correcting problems in the production process.
Finished product inspection: Before leaving the factory, we will conduct strict inspection and testing on all products. The inspection includes aspects such as appearance quality, insulation effect, impact resistance, and sealing. Only products that have passed strict inspection and testing can be sold after leaving the factory.
After sales service: We have also established a comprehensive after-sales service system to provide consumers with high-quality after-sales service. If consumers encounter any problems or doubts during use, we will respond promptly and handle them properly to ensure that their rights are protected.
3, The Importance of Implementing Standards and Quality Control
Implementing standards and quality control are crucial for the stainless steel insulated cup industry. Firstly, implementing standards can ensure that the quality and safety of the product comply with
