How to make a water bottle in the factory?

1. Raw material selection: the cornerstone of quality

The quality of water glasses starts with the selection of raw materials. We strictly screen raw materials such as food-grade plastics and stainless steel that meet national standards to ensure that they are non-toxic, harmless, odorless, and have good heat resistance, corrosion resistance and mechanical strength. For example, plastic water cups use environmentally friendly materials such as polypropylene (PP) or polycarbonate (PC). These materials are not only lightweight and durable, but also recyclable and in line with environmental protection concepts.

2. Production technology: meticulous craftsmanship

1. Plastic water cup production

The production process of plastic water cups includes injection molding, blow molding, printing and other links. First, the raw materials are heated and melted by an injection molding machine and injected into the mold to form the prototype of the cup body and lid. The cup body is then blown into the desired shape through a blow molding process while ensuring uniform wall thickness and smooth appearance. Finally, advanced printing technology is used to print exquisite patterns and text on the cup body and lid to enhance the product's appearance appeal.

2. Production of stainless steel water cups

The production of stainless steel water cups involves multiple processes such as shearing, stamping, welding, and polishing. First, the stainless steel plate is cut to the required size, and then the shape of the cup body and cup lid is punched out by a punching machine. Then, laser welding or argon arc welding technology is used to weld the cup body and lid together to ensure sealing and durability. Finally, through polishing treatment, the surface of the water cup is made as smooth as a mirror, improving the product quality.

3. Quality control: the guardian of strict control

We know that quality is the lifeline of an enterprise, so we have established a complete quality control system. From the entry of raw materials to the delivery of finished products, strict quality inspection points are set up for every process. For example, during the production process of plastic water cups, we will test the wall thickness, transparency, sealing and other indicators of the cup body; stainless steel water cups need to test their corrosion resistance, pressure resistance, sealing and other properties; only products that pass all testing points can enter the next process or finally leave the factory.

4. Environmental protection and innovation: practitioners of sustainable development

We always regard environmental protection and innovation as the core driving force for corporate development. During the production process, we use advanced environmental protection technology and equipment to reduce the emission of waste gas, waste water and waste residue to achieve green production. At the same time, we continue to develop new products and new technologies to meet the increasingly diverse needs of consumers. For example, we have launched water cup products with multiple functions such as heat preservation, cold preservation, and leakage prevention, as well as environmentally friendly water cups made of degradable materials to provide consumers with a more convenient and environmentally friendly use experience.

5. Professional manufacturing, quality assurance

From raw material selection to production technology, to quality control and environmental innovation, we always adhere to the concept of professional manufacturing and are committed to creating high-quality, safe and reliable water cup products. We believe that only through strict quality control and continuous technological innovation can we win the trust of consumers and market recognition. In the future, we will continue to work hard to provide consumers with more high-quality, environmentally friendly water cup products and create a better life together.
