What would be the maximum amount of molted plastic you could push into a mould with the injection machine, without the quality of the product deteriorating? Could you fill up a mould in multiple pushes, allowing for products that need more plastic? I am thinking about products that are 10x10x10cm (not solid, for example a lampshade). Of course there’s also the compression machine, but I wonder if it’s more efficient (time needed, energy consumption) compared to injection when using one mould. Of course you could put multiple moulds in the compression oven, but that will cost more. Is there also some kind of maximum weight you can screw underneath the injection machine (mould+plastic)?
