1. Production process

　　Diabetic PU foam insoles adopt advanced manufacturing technology to ensure the comfort and functionality of the insoles. The following is a detailed introduction to the production process:

　　Material preparation: Use high-quality PU (polyurethane) foam material, which has excellent elasticity and wear resistance and is suitable for making diabetic insoles. Make sure the materials are free of impurities, odor-free, and meet hygienic standards.

　　Mold design and production: Design appropriate insole molds based on the characteristics and needs of diabetic patients’ feet. The mold should accurately reflect the shape and curves of the foot to ensure a fit and support for the insole.

　　Foam molding: Put the PU foam material into the mold, and through a specific foaming process, the material expands in the mold and fills the entire space. During this process, foaming temperature, pressure and time need to be precisely controlled to ensure that the density and elasticity of the insole are optimal.

　　Demolding and trimming: After the insole is completely solidified in the mold, perform the demoulding operation. Perform necessary trimming and polishing of the demoulded insoles to ensure that the surface is smooth and flawless.

　　Post-processing and packaging: Clean, disinfect and other post-processing of insoles to ensure that they meet hygienic standards. Finally, it is packaged for storage and shipping.

　　2. Finished product process

　　From raw materials to final products, diabetic PU foam insoles go through a series of processes to ensure that their quality and performance are at their best. The following is an introduction to the finished product process:

　　Quality inspection: Strict quality inspection is carried out on the formed insoles, including appearance inspection, dimensional measurement, elasticity test, etc., to ensure that they meet the design requirements and quality standards.

　　Functional testing: Conduct functional testing on insoles, such as support performance testing, cushioning performance testing, etc., to evaluate their effectiveness in actual use.

　　Comfort evaluation: Invite diabetic patients to try on the shoes and evaluate the comfort, fit and other indicators of the insoles in order to continuously optimize product design.

　　Labeling and packaging: Mark qualified insoles, including product name, specifications, production date and other information. It is then packaged to ensure protection from damage during transportation and storage.

　　3. Product advantages

　　Compared with traditional insoles, diabetic PU foam insoles have the following significant advantages:

　　Excellent support performance: PU foam material has excellent elasticity and support performance, and can adapt according to the shape and pressure distribution of the foot, providing personalized support and comfort.

　　Buffering and shock-absorbing effect: PU foam insoles can effectively absorb and disperse the impact of walking, reduce vibration and fatigue on the feet, and help protect foot health.

　　Breathable and comfortable: The insole material has good breathability, which can keep feet dry, reduce bacterial growth, and reduce the risk of infection.

　　Durable and easy to maintain: PU foam material is wear-resistant and durable, and can maintain its shape and performance for a long time. At the same time, the insole is easy to clean and maintain, making it convenient for patients to use daily.

　　In summary, diabetic PU foam insoles have become an ideal choice for diabetic patients due to their excellent support performance, cushioning and shock-absorbing effect, breathable comfort, durability and easy maintenance. During use, patients should correctly use and maintain the insoles according to the product instructions to ensure their best use.
