Hello! I have been researching on this page for a couple of weeks now and each time I am closer to know what I want to do with the information of this community. I will make a compression machine and I have seen some different ways to use the molds: #1. The one Dave shows in his videos: heat the oven, put the plastic in the mold and use the press built into the machine. #2. Another technique I have seen is to heat the plastic in the open mold, then take out the mold and use a press to mold the piece. #3. And the other is to heat the plastic in a tray and pour the half melted plastic to a mold outside and exert pressure with a machine. While the first 2 methods are made with metal molds, in the last I have seen a video (https://vimeo.com/josecamachopd/pplastic) where they make MDF molds. I wanted to know, according to your experience, the pros and cons of these different types of finishes. I suppose that in the technique #3 the molds are more economical, and in addition, you can heat the plastic in a conventional oven (not the PP machine). What can you tell me about these techniques, in terms of finished products and production times or something else. Thank you!
