Rosineer 1.5" x 1.5" Square Pre-Press Mold



Rosin pressing tips

Rosineer Pre-Press Mold improves yield and reduces chances of filter bag blowouts by compacting your flowers into a 1.5"x1.5" square wafer / puck.  Similarly to our rectangular pre-press mold,  the square one consists of three parts, which are also made of food-grade anodized aluminum. 

Puck dimensions
 1.3 x 1.3 inch / 33 x 33 mm
Press dimensions when assembled, L x H x W
 1.5 x 1.5 x 2.3 inch / 40 x 40 x 60 mm
 Anodized aluminum, food-grade
Rosin pressing tips

What is rosin and how it is produced?

Rosin is a concentrated extract of cannabis plant which is produced by applying heat and pressure to the plant parts (usually flowers or hash and kief) to squeeze out a translucent, sappy substance.

What do I need to start making rosin?
You need a rosin press, a parchment paper sheet, a collection tool, and your precursor. Additional items that you may want to use when pressing rosin are filter bags, pre-press molds, non-stick mats, etc.

How do I make rosin?

Prepare your plant material. Make sure it is kept at the optimal 62% humidity.

Place the plant in a folded parchment paper sheet.

Turn on your press machine and set your desired temperature and timer.

When the press plates reach the right temperature, place the parchment paper with your plant material on the bottom plate and operate the machine according.

When done, remove the parchment paper, get rid of the pressed plant parts, and gather rosin using your collection tool.

What are the recommended press settings?
For Cold Pressing: 160°F - 190°F, for 1 to 5 minutes or longer. Cold pressing produces terpene-rich rosin but with a sacrifice in yield.
For Hot Pressing: 190°F - 225°F, for 40 seconds to 3 minutes. The hotter you press, the higher yield you’ll get, but the high temperature causes a drop in rosin quality.
Flowers can be pressed at 190°F - 225°F for 30 - 180 seconds.
Refined precursors such as hash, kief, dry sift are usually pressed at 165°F - 195°F for 60 - 130 seconds.

What filter bags should I use?
We carry three mesh sizes: 25, 100, and 160 microns. 25 micron bags are best used with fine grain materials such as kief, bubble hash, and dry sift. 100 micron bags give the best filtration and highest quality output for flower rosin, but you may see some reduction in yield. 160 micron filters are usually the optimal type of bags for flowers; they result in good yield and quality rosin.

Questions & Answers

Have a Question?

Ask a Question
  • How long does it take to press

    You are going to use the mold to compact, remove extra air between flower particles, make it of equal thickness, and to prepare for pressing. I'd say it would take you less than a minute to perform this task.

  • Can this be used to press Kief info hash?

    Yes, you may press kief or hash with this pre-press.

  • Will the 1.5 inch pre-press square too large to use with the Presso ? Will it squeeze out the sides of the plates ? Would the 30mm be a better choice?

    The internal size or puck size of 1.5"x1.5" square mold is 1.3"x1.3", so it fits PRESSO. The 30mm cylinder one also works with PRESSO.

  • How much flour can you put in the prepress at a time

    It can pre-press about 7 - 20 grams depending on how thick you need for the puck.
