The telescopic folding clothes drying rack adopts a multi-material composite structure, which aims to integrate the advantages of different materials to meet diverse performance requirements, but this process also faces many process challenges.
First of all, common multi-material combinations include metal and plastic. Metal parts such as aluminum alloy or stainless steel have high strength, good load-bearing capacity and durability, and can be used as the main frame of the clothes drying rack to ensure that it will not be easily deformed or damaged when bearing the weight of clothes.
Plastic materials are often used for some non-load-bearing parts, such as the hooks of the clothes drying rack and the protective covers at the joints. Plastics have the characteristics of light weight, good insulation and low processing cost. Its application at the joints can reduce the friction and wear between metals, play a buffering and protective role, and also reduce the overall weight, making it easier to operate and move. This material combination achieves the complementary performance of strength and lightness.
However, the multi-material composite structure brings a series of process difficulties. In the material connection process, the connection method of metal and plastic needs to be carefully designed.
For example, when using adhesives for connection, it is necessary to ensure that the adhesive has good adhesion to both materials and can maintain the stability of the connection under different environmental conditions (such as humidity and high temperature). If a mechanical connection method is used, such as screw fixing, the difference in thermal expansion coefficients between metal and plastic must be considered to avoid loose connections or stress concentration due to temperature changes, which will affect the structural integrity of the clothes drying rack.
In addition, the surface treatment process also faces challenges. The metal part may need to be anodized, painted, etc. to enhance rust resistance and aesthetics, while the plastic part may need to be surface modified after injection molding, such as frosting and polishing. In composite structures, it is necessary to ensure that these surface treatment processes do not affect each other, and that the surface coatings or treatment layers of different materials can work together to maintain good performance, such as weather resistance and wear resistance, during long-term use.
Finally, during the manufacturing process, the complexity of mold design and manufacturing increases. Because multiple materials are involved, the mold needs to consider the molding process requirements of different materials, such as the coordination and connection between metal stamping and bending molds and plastic injection molds. At the same time, during the assembly process, it is necessary to ensure the precise assembly of parts made of different materials to ensure the dimensional accuracy and normal function of the entire telescopic folding clothes drying rack, which puts higher requirements on the refined management of the production process and quality control.
