Embodiment Construction
[0037] The invention provides a hot-melt bonding process with stable and reliable process, short time and high final bonding quality.
[0038] The structural features and advantages of the present invention will be described in detail below by taking the application of this process to bond a metal ring on the shell of a mobile phone as an example.
[0039] The invention relates to a hot-melt bonding hot-pressing process, which is to heat the thermoplastic polymer film material of the fiber-reinforced structure without hardening treatment as an adhesive film to a molten state, and in this state, the adhesive film serves as a connecting link with the adhesive film. The two parts to be bonded are welded, and when cooled to normal temperature, the adhesive film in the molten state solidifies and hardens, and is firmly bonded to the parts to be bonded, thereby forming a connection between the two parts to be bonded. Such as figure 1 , figure 2 Shown, the present invention mainly...
