This type of finger spring product, from the perspective of installation methods, is most commonly available in two types: adhesive and clip-on. The adhesive type typically uses PSA pressure-sensitive adhesive as the bonding agent, offering high bonding and shear strength, as well as transferability. Moreover, the adhesive finger spring is more space-saving in structure, requiring no additional installation components, making it suitable for applications in narrow spaces. The image in Figure 1 shows a special type within the EMS finger spring series, the folding finger spring. The structural diagram reveals that the bottom of this type of spring extends a sharp-angled folding structure, which serves two purposes: first, it enhances the compression elasticity of the spring, allowing it to withstand greater compressive stress; second, it protects the finger structure of the spring, preventing damage from repeated compression and impact. Products with this structural feature are particularly suitable for various applications involving frequently opened and closed shielding doors and covers. When selecting, it is recommended to reserve a compression range of 20% to 60%. Specific size parameters can be referenced in the model size table in Figure 2, selecting the appropriate product based on your needs.
