These custom pre-presses are sized to fit our 3″ screen bags. This mold is a simple yet effective method of quickly condensing your material for easy insertion into the bags before pressing. You will get a perfectly sized slab to fit inside the bag. This tool will not only save you time, but will help you achieve more uniform results!
Dimensions: 2.5″ x 2.5″ (2″ deep)
These dimensions are the size of the inside of the mold. The thickness of the brick you can make depends on the amount of material added, but you have 2 inches of depth to work with. Bricks that are 1/2″ or thinner will fit inside the 3″ bags.
Recommended bag size: 3″ x 6″
About the bags:
Our bags are 3″ x 6″, inside-out stitching. Dye-Free, Food Grade nylon rated to 430ºF (375º is maximum recommended).
To aid in compression, pick up a 1 ton arbor press or a 600 lb. clamp. Pro Tip: Hold the compression for about a minute. Time will help solidify the brick, making it less likely to re-expand when pressure is released.
