Let me introduce you
to the stm 4.0

Hello.


A Technically Advanced Commercial Rosin Press


Our commercial rosin extraction system uses food grade materials, industrial mechanical components, and high tech control systems to automate and streamline the process. Only heat and pressure are used for extraction – no chemicals, no solvents. The final product is ready to use in minutes and does not require any post purging of solvents or additives. When compared to BHO (butane hash oil), the two are aesthetically indistinguishable. Rosin, when made properly, retains just as many valuable terpenes that account for aroma and flavor. However, in a lab test, rosin will never contain a single part per million (PPM) of residual hydrocarbon. In other words, your product will be 100% Natural Rosin and solvent-less when using our system.


The stm 4.0 – Difference is in the Details!

Engineered for Accuracy & Reliability

The stm 4.0 Rosin Press is fully automated and the only commercial rosin producing press on the market.  Not only is the stm 4.0 ready to use right out-of-the-box, but it is designed towards maximizing your profits and Return on Investment (ROI) from the first day.

The stm 4.0 is precisely engineered with industrial mechanical components to ensure consistent, streamlined and dependable performance with superior results in a professional, small footprint.

This Rosin press is a powerful work of art!

Why the stm 4.0?

Powerful Industrial Commercial Components

The stm 4.0 is encased in SAE 304 stainless steel and uses large, 8″ x 12″ food grade 304 stainless steel, interchangeable platens for the ultimate in customization, flexibility and productivity.

These platens are the largest available & can press up to 4000 lbs of even, controlled pressure while reaching operating temperatures in under 10 minutes to evenly heat the platens and maximize efficiency.

*Our extensive testing has discovered that between 2000-3500 lbs of EVEN pressure and between 180-220 degrees of ACCURATE heat is optimal for Rosin extraction. Anything above that does not necessarily increase yields while possibly damaging terpenes.


Precise Touch Control Operation

Precisely operate everything from temperature, pressure, dwell and press time at the touch of a button on the ergonomic, 7″ touch screen control panel.

The touch screen is fully programmable for multiple user presets which allows for the ultimate in customization when using different materials, temperatures, dwell and pressure settings.

The stm 4.0 will operate automatically with your settings presets or run it manually  – giving you the choices which works best for your environment.


OHSA & WSHA Compliant Industry Leading Safety Features

The stm 4.0 Rosin Press is designed with a 5-point safety system including:

  • Poly-Carbonate Surround Shield (prevents access from rear or sides of press)
  • Infrared Light Curtain (immediately stops press if hand or another object penetrates the infrared beam)
  • Emergency Stop Button (immediately shuts down the press)
  • Lock-Out-Tag Switch (locks out machine so it cannot be turned on)
  • Thermal Heat Barriers limit heat transfer to other parts of machine

Return on Investment (ROI)

The stm 4.0 is a high output, high yield, commercial press which can maximize your profit potential almost immediately.

Earn your investment back in days, not months or even years with other processing systems.

The stm 4.0 requires no special trained staff and no state mandated regulations or inspections.

You can start earning profit from your first day!
