We were approached by an Italian packaging equipment supplier who had observed consistent problems with the original metal coupling on their machines.
They were coping with harsh noise, growing maintenance costs and corrosion risk in a food processing environment when they were in production.
However, more importantly the coupling was not durable enough for continuous long run working and many overload scenarios often lead to a broken motor and Transmission line.
This time it was not just a replacement part. They required a more reliable solution for everyday manufacturing.
We designed a custom nylon coupling using PA66 GF30 engineering plastic which was available in China and machined through CNC, to replace the original metal component.
A typical example of where utilizing a custom nylon coupling will optimize performance while maintaining cost-effective packaging.
The new design aided compared to the metallic version:
The blue nylon material was also good for optical detection systems which are widely used in the food production lines.
Overload protection was a major requirement, however;
Due to potential partial or total malfunction under abnormal load conditions that could lead to an amplitude spike and damage the motor and transmission system, the coupling required controlled slip behavior.
Depending on the machine, we then changed the torque structure and adjusted it according to their setup of the customer, ensuring stable and predictable performance during operation.
CNC Machining
With CNC machining, we can easily control critical dimensions and ensure stable batch production.
Prior to mass production, we provided sample confirmation and inspection reports so that the customer could check dimensions and function.
Once approved, batch production was performed with an appropriate Q/C process in place to ensure consistent and repeatable results.
The custom nylon coupling fixed this issue, and here's how.
The customer then implemented the part into their standard equipment BOM for replicated production.
We can help with quick turnaround prototype and low volume batch production for custom nylon coupling, CNC machined coupling or PA66 GF30 parts working in packaging equipment or industrial automation systems.
Send drawings or existing samples along with pieces for manufacturability Check Before Production.
