Out of stock


These custom pre-presses are sized to fit our 2″ 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 brick to fit inside the bag. This tool will not only save you time, but will help you achieve more uniform results!

Dimensions: 1.5″ x 3.5″ (2″ deep)

These dimensions are the size of the inside of the mold. If you make the bricks 1/2″ or thinner, they will fit perfectly inside the 2″ bags. For best results, we recommend between 15-30g of material.

Recommended bag size: 2″ x 4.5″

About the bags:
The bags are 2″ x 4.5″, inside-out stitching, dye-free, food-grade and rated to 430ºF/220ºC (375ºF is maximum recommended)..

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 (1.5″ x 3.25″). 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.
