Makes Process More Reliable

AOD, India makes ophthalmic devices. The ophthalmic incision knife that they make has a SS blade that needs to be bonded on to PC handle. AOD was using a 2 Part epoxy for this process however it was time consuming and depended largely on operator skill. Customer wanted to increase production to 1.2 million units / annum and the process time with a 2-k epoxy was a constraint. Using a 2-k epoxy involved mixing both parts and was time consuming. The mixed epoxy also had limitations on pot life and resulted in wastages of mixed epoxy

Withstands Autoclave Sterilization

Bio-Rad Medisys, India manufactures Urological & Gynecology catheters. Bio-Rad required to bond a variety cannulae (SS, PU & PVC) to hubs (ABS, Nylon & PVC). In some cases with a radial clearance of 0.2mm. They tried a competitive cyanoacrylate but it could not withstand autoclaving* process and de-bonded.

Clear Bond Line Enhances Component Aesthetics

Kasturi Machine Builders is a manufacturer of special purpose machines in India. Kasturi also assembles oil filters made of polycarbonate fo their machines. They were using a competitive cyanoacrylate to bond lower and upper casing parts of the filter – however, the casing was stress cracking and causing leaks. The cracked casings needed to be replaced - adding to their costs. Also the blooming caused by cyanoacrylate affected the aesthetic appearance of the transparent casing.

Strengthens Assembly, Prevents Moisture Ingress

Train bogie wheels are assembled utilising a heavy interference fit of 0.001” per inch of axle diameter, (typically 0.009” for a 9” diameter shaft). In addition, press-on tonnage of between 65-110 tonnes must be achieved and documented to ensure optimal assembly strength.
This can be an extremely difficult task, and the consequences of poor assembly can be expensive or even catastrophic. Therefore if metal pick-up occurs during assembly, the components will be scrapped, and if the tonnage is not achieved within specification, the wheel and axle must be separated and re-matched.
