10 Best Pre Press Molds For Rosin Pressing

10 Best Pre Press Molds For Rosin Pressing
Rosin Press

What is a pre-press mold used for in relation to rosin pressing? 

A pre-press mold will enable you to compact any flower or kief, to make it easy to press more rosin in very little time. It helps to reduce blowouts while improving your yields. A pre-press mold is significant for rosin lovers when it comes to time and yield. When you use a pre-press mold, you can compress loose materials and, therefore, make them shaped perfectly in a ‘puck’ that fits easily in your rosin bag. You can also use the clamp or arbor press for better pressure. 

In relation to rosin pressing, a pre-press mold makes it possible to get most of the oil out through pressing, which is ideal for rosin enthusiasts hoping to rake in some profits through rosin pressing.

A pre-press mold also makes it possible to press your rosin at just the right pressure; this is because applying too much pressure can destroy your rosin. Therefore, although it still requires pressure, a pre-press mold makes it possible to provide just enough effort to get the best results.

As there are different kinds of pre-press molds to choose from for rosin pressing, you can press any flower type or kief, no matter the texture. Also, in addition to improving yield, using a pre-press mold means that you can limit the chances of any filter bag blowouts. This is because your flowers are compacted inside a very small puck. 

How to use a pre-press mold

The pre-press molds’ usage appears to be pretty easy for most people, and even first-time users. Depending on the size of the prep-press you are using, all you need to do is simply fill up your mold to the upper edge. Most users get excellent results when they use around 3 to 4 grams while using press molds. You can also fill the same amount each time, and add a little hand pressure to produce a perfect rosin coin at the end. 

One rule of thumb is that if you use low-quality flowers, you will end up with low-quality rosin – no matter the pressing time, pressure, or temperature you use. On the other hand, if you use high-quality flowers or input material, you will produce high-quality outputs – all things being equal. When using a pre-press mold, it is also essential to work under the right temperatures, whether pressing flowers or kief. 

As stated before, the process of using a pre-press mold is quite simple. When using a pre-press mold, you first begin the process by wrapping your pre-press mold’s inner areas with parchment paper. Once done, you can start picking your flower using just the bottom piece in your pre-press mold.

Once you have a pack of flowers, you can then position the Pre Press’s top piece inside the Mold. When you have all the pieces put together, use your press to pressure down the top part of the pre-press mold. Doing this will mold the flower into place. When you complete everything, continue by pushing through the pre-press mold to get the pressed flower out along with the bottom piece.

 

Is this a form of solventless pressing? 

Rosin is considered a solventless process. This means that it relies solely on heat and pressure to squeeze the produce and terpenes from the material source against what many people regard as the chemical (solvent) process used to produce rosin. Therefore, this makes press molds for rosin pressing also a form of solventless pressing.

For many consumers and rosin lovers, the main advantage of the solventless process is that it does not contain any of the residual hydrocarbon usually found in the solvent extracts. 

There are different types of solventless pressing as far as making solventless rosin is concerned – flower, harsh, solventless sauce, whipped buddha, and live rosin. However, the solventless pressing process keeps evolving constantly- new processes and modifications are introduced frequently. 

The solventless process is also one of the most inexpensive pressing methods and, therefore, the most popular. As mentioned earlier, the solventless pressing method relies mainly on pressure and heat to extract. Therefore approach demands that you provide the right temperature and pressure, depending on the type and texture of the material you are using. Again, this is different from the solvent-based extraction process, which requires some volatile chemicals in the extraction process.

 

Do you need a rosin bag to use with the mold?

The question of whether it is essential or not to use a rosin bag with the mold is not a new one. A rosin bag may not be necessary when it comes to pressing the rosin.

However, there are many reasons why using a rosin bag is vital in bolstering your rosin’s success. One reason for this is that when you pack your source materials into a rosin bag before taking it onto the press, it is less challenging to handle the material.

Also, it makes it less difficult to control the placement of the materials between the plates – this ensures that not only is the purity of your final product enhanced, but it also improves or increases your yields significantly. 

Although anyone can pretty much get away with pressing very good rosin without necessarily using a rosin bag, you will only end up spending too much time to handle your source material carefully. It means that you will lose out on quality control, in turn, will potentially leave your yield stuck inside the material without the rosin bag.

Aside from control and time-efficiency, using a rosin bag also means that you will produce much more transparent rosin. The reason for this lies in the fact that the rosin bag serves as a filter that allows the right ingredients in the rosin to pass out from the source material onto parchment paper while you press.
