Bom dia. quero entra em contato com a equipe de produção que ultilizam a maquina Vacuum Forming, para esclarecer duvidas ao corte poz moldado.... qual tipo de maquinario e ultilizado para esse tipo de acabamento... estarei aguardando meu e-mail " juniorsulino@hotmail.com"
I have found that more vacuum and vacuum holes around the base of my parts work fine to get rid of webbing. Also looked like the material was quite thick. I have a different setup where I have my molds drilled with 0.7mm holes through the mold to a pocket on the underside of the mold. The mold sits over a vacuum hole in the bed where I have a vacuum line attached. I only get vacuum where I need it. I mold parts up to 2 1/2' X 1 1/2' with 1/8" to 1/4" HDPE and around a 4" draw with no trouble.
@domeafava I agree. On this pull, I had the molds on small washers to act as risers so that the holes underneath would do some work, which they did but the webbing still occured. I think maybe the molds were just too close together. Also, the plastic I used on this one was only .030" I believe so it heated really fast!
@Psychlist1972 Haha, yeah it was pretty boring for the first 20 minutes! :P Waiting on the heater was the longest part. Luckily I just edited (most) of that out!
Rounding the corners of things as much as you can I think will help. Sharp corners seem to be the most troublesome spots. Also, I think the plastic got way too soft here, and that will making the webbing worse. If it does happen, then yes, you'll just have to heat and try another sheet.
