Hello, we have encountered an issue with our plastic closures becoming brittle during the production process. Despite conditioning them for 48 hours at 30 degrees Celsius, we are still facing this problem. We are exploring potential solutions to maintain the elasticity of the closures, including the use of UV lights. However, after conducting research, it seems that the closures cool down and become brittle within 2 hours. If anyone has any ideas on how to address this issue, please let us know. Thank you.
Ajay: Can you confirm if these plastic enclosures cool down within 2 hours? Are they manipulated after 48 hours of cooling, or do they need to wait for 48 hours before manipulation? Additionally, please specify the operations being carried out on the enclosures. Are these operations conducted at a temperature of 30C? Furthermore, can you provide details on the type of plastic used for the enclosures? Lastly, when were they first identified as brittle? Was there a modification in the process that led to this change, or have they always been prone to brittleness during this process? Have there been any improvements in throughput or changes in tooling? Sincerely, Howard howard@motordiagnostics.com
Hello, there appears to be an issue with the turquoise closures we've been using during promotions. I've noticed that the color may be affecting the performance of the closures. To address this, I have raised the temperature in the conditioning store to 30 degrees Celsius and am closely monitoring the situation. The closures are being transferred from the hopper to the capper to seal the bottles, using the same tools which have recently shown signs of brittleness. Kind regards, Ajay.

I'm wondering if your issue might be related to the rate at which the plastic is cooling down post-molding? Rapid cooling sometimes results in micro-stresses that can make the plastic brittle. If you haven't tried it yet, perhaps consider a slower cooling process or the use of annealing process to help relax the internal stresses. Also, certain additives can increase plastic's resistance to brittleness. It might be worth exploring these avenues before investing too heavily in UV treatments, which might not address the root cause of your issue.
Hi, it seems you're experiencing a common issue with the plastic manufacturing process. One approach could be adjusting the cooling rate post-extrusion — the rate at which they're cooled could be contributing to their brittleness. A too-rapid cooling process can cause the plastic to turn brittle. It might also be worthwhile examining the composition of your plastic material itself. Certain additives or fillers can help enhance the flexibility of the plastic. As for the UV lights, in my experience, they are more effectively used for disinfection or for curing certain coatings, not necessarily for affecting the physical properties of the plastics. Hope this helps!

Answer: 1. Why are my plastic closures becoming brittle during the production process? - Plastic closures can become brittle due to factors such as inadequate conditioning, cooling too quickly, or exposure to certain environmental conditions.
Answer: - It is recommended to condition plastic closures for a sufficient duration at the appropriate temperature to maintain their elasticity.
Answer: - While UV lights may have some benefits, it is essential to consider other factors such as cooling rate and environmental conditions to effectively prevent plastic closures from becoming brittle.
