PP Random Copolymer Moulding Issues: Thin wall container

Hi, I am trying to mold thin wall container with PP random copolymer (for clarity) but I see waves in my finished item. I have checked and tried almost everything.
mold cooling, cooling timing, increase injection pressure, change material but seems that waves are not going away.

Also, random copolymer is soft, what can I mix to increase strength of finished product little bit without compromising clarity?

Try changing screw RPM or augmenting injection speed. Another thing you should check is your temperature profiles, since you work with thin wall I assume your cycle it’s really fast and the resin stays less than 5 mins in the barrel so you can increase your middle and front temperatures a little without degrading the PP

This happened to me in the past with clarified PP but solved it augmenting screw RPM’s (120-150)and augmenting injection speed to 300mm/s.

Sadly I can’t advice you about your last question, since we inject thin wall containers with IML the label adds strength and rigidity to the container.
