Have not actually used them to make rosin but tested them and found that they heat up quickly and maintain the temperature set point perfectly. This is a great buy.
Right out of the box and onto my press 👍. This is my first time pressing and I found these to be very easy to use. Definitely recommend with the pre press mold.
Only complaint I have is the control box I thought had magnets to hold it to the shop press when in use. It has nothing, not even rubber feet to prevent it from sliding off the top of the press
3x5 DIY Caged Rosin Press Kit - Build A 10-12 Ton Rosin Heat Press Machine for Personal Use
The caged press plates work great the four times I have used them. I built a frame out of boxed steel and C channel to hold the plates and a twelve ton Jack. I have pressed 2 gram pucks of last years flower, with a yield of a over .2 grams each time.
I am looking forward to using it on this years harvest in the coming weeks.
