How do we stop Sticky moulds ?
Anyone in the forum know what we should be using to stop the plastic sticking to our moulds. we’ve been using a silicon based release agent that doesn’t quite do the job.
I’m not sure which technique or type of plastic you use.
However the plastic that mainly sticks is HDPE, you could try to use another type like PP (quite similar). Also if you inject or press hot plastic in a cold mold it doesn’t stick to it. Most of the times it happens when you heat up the plastic together with the mold (compression machine) potentially you could see if there is another way to get your plastic into the mold or switching techniquesToggle replies
