Adhesive dispensing station

Case Study 2—Process Development and Validation of an Adhesive Dispensing Station... 

There are three factors related to the set-up of the adhesive dispensing station that may impact the final bond strength. They are as follows ... 

Figure 4 D5max method. Steps (1) Worker loads magnets to automatic feeder/adhesive dispenser also brings motor cans to second worker station. (2) Second worker applies activator to can housing with a semiautomatic dispenser. (3) Second worker then places can over magnets that have been previously placed into fixtures robotically. (4) Turntable cycles, engaging fixture pressure mechanism. (5) Bonded parts are automatically off-loaded to continue in production.

Epoxies, however, are not always the best adhesive for bonding small engineering plastic components as the dispensing of the two-part versions can be problematic (see Section 8.1) and they are relatively slow to cure compared to most adhesive technologies (although the cure speed can be accelerated by heat). Some hardeners can be toxic and have a high odour and so this can cause health and safety issues in the workplace or at the dispensing station.
