Hi, How are you?? i have a projecT in my university on the production of recycled LDPE tables, but i have had problems with the final result because the table comes out with many bubbles of internal airs and i need that the result is free of these.
Does anyone have any idea how to eliminate them?
Have a nice day!!
Do you have any pictures of your set up?
1. Apply more pressure while it is still at full temp.
2. Shred or cut up your plastic in smaller pieces before melting and melt in small layers, pressing down hard as you add in the next layer.
I’ve see videos where people actually “pop” bubbles but in my experience you’d have to get your plastic way beyond melting temp to be able to do that and it seems like it would burn long before then?
