How is the TPU eye protector inflatable massage airbag produced by high-frequency heat bonding?
The high-frequency heat-sealing production process of the TPU eye protector inflatable massage airbag is a precision manufacturing process involving multiple links. The following are the main steps of the process:
Ⅰ. Design stage
Designers need to make creative ideas and structural designs according to customer needs and uses. Factors that need to be considered in the design stage include the size, shape, inflation pressure, material selection, and safety of the airbag. At the same time, designers also need to make hand-drawn sketches and preliminary three-dimensional modeling to provide accurate reference for subsequent processing and production.
Ⅱ. Material selection
TPU (thermoplastic polyurethane) is a highly elastic and weather-resistant material with good wear resistance, oil resistance, and tear resistance. When selecting TPU materials, it is necessary to consider the product's use environment and life requirements to ensure that the airbag maintains excellent performance and durability during use. In addition, TPU materials are also environmentally friendly and degradable, which conforms to modern green consumption concepts.
Ⅲ. Mold making
According to the requirements of the design drawings, the mold maker begins to make the mold. The mold is a key factor in determining the shape and quality of the product, so its accuracy and stability need to be guaranteed. Mold making usually uses CNC machine tools for precision processing to ensure the smoothness of the mold surface and the accuracy of the size. After completing the initial mold, it is necessary to conduct a trial mold, pressure test and air tightness test on the mold to ensure that the mold can meet production requirements.
Ⅳ. High-frequency heat sealing production
High-frequency heat sealing is a key step in the production of TPU eye protector inflatable massage airbags. The following is the specific process of high-frequency heat sealing production:
1.Equipment preparation: Use a high-frequency heat sealing machine or a high-frequency welding heat sealing and melting high-frequency machine. These devices use the principle of high-frequency electromagnetic field to make the internal molecules of TPU material vibrate rapidly and generate heat through high-frequency oscillation, thereby achieving rapid fusion and sealing of the material.
2.Material cutting: Accurately cut TPU material according to mold size.
3.Placing material: Place the cut TPU material on the workbench of the high-frequency heat sealing machine to ensure that the interface is aligned and fully contacted.
4.High-frequency oscillation and heating: The high-frequency generator inside the equipment generates high-frequency current, which is input into the mold through a specific conduction system to form a high-frequency electromagnetic field. Under the action of the high-frequency electromagnetic field, the internal molecules of the TPU material vibrate rapidly and rub against each other, generating heat, causing the material to quickly heat up to the melting point.
5.Fusion sealing: Under the pressure and temperature control of the mold, the TPU material heated to the melting point quickly fuses and solidifies to form a solid fusion layer or seal.
Ⅴ. Quality inspection and finished product delivery
After completing the high-frequency heat-sealing production, the product needs to be quality inspected. Quality inspection is a key step to ensure product quality, including appearance inspection, size inspection, performance inspection and other aspects. Appearance inspection mainly checks whether the product surface is smooth and flawless; size inspection is to accurately measure the various dimensions of the product to ensure that it meets the design requirements; performance inspection is to test the functions of the product, such as inflation pressure, durability, etc. Only products that pass the quality inspection can be identified as qualified products and allowed to be shipped.
The high-frequency heat-sealing production process of TPU eye protector inflatable massage airbags is a precision manufacturing process involving multiple links such as design, material selection, mold making, high-frequency heat-sealing production and quality inspection. Through this process, TPU eye protector inflatable massage airbags with high strength airtightness and good comfort can be produced.
