- Why Use Tape?
- There are many reasons why tapes are replacing traditional fixing methods. Among these is the strong and reliable bond that tapes provide and their additional functionality such as sealing, shielding, insulating and cushioning. In addition to these benefits, joining with tape offers greater design options, product quality and enhanced manufacturing efficiencies.
- Why Customise Tape?
- A customised adhesive component offers a number of benefits to designers and engineers. Product designs can be streamlined with invisible joins and product manufacture is made simple with a convenient and easy to handle component. Adhesive parts can be designed with application aids, or for use in automated assembly processes.
- Tape vs Traditional Fixings
- Tape is replacing traditional fixing methods across many applications. Here we compare the benefits of using a tape in place of traditional fixing methods.
