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 4.5″ (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 and rated to 430ºF/220ºC.

About the paper:
The papers are made with double sided silicone coated genuine vegetable parchment, FDA approved and cut to fit inside our pre-presses (2.5″ x 4.5″). They will keep material from sticking to the metal surfaces of the mold, speeding up processing and cleanup.

Helpful tools:
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.

Made in USA.
