Our Story

Whenever I think of the DIY heat press I made by myself in 2014, it is really unbearable to look back. Sometimes, I will waste a whole day in solventless extraction and end up with nothing. I almost forgot how many prototypes I made in total. To this day, most of them are lying quietly in my barn.

As we all know, heat solventless extraction combines of heat and pressure. These two dimensions are also an important criterion for choosing a heat machine. 

Manual heat press is my first choice. Although it is cheap and easy to use. Since it cannot provide enough pressure. It can only press about 3.5-5g flower or hash etc. The quality of heat is very good, but the yield is relatively poor.

In recent years, I have my efforts and attention to vertical jacks and hydraulic jacks. Because they are both easy to operate, and the pressure provided is much higher than the manual one. However, new challenges have jumped out again. The machine is under heavy pressure, and the frame of heat machine is required to be strong enough, otherwise the equipment will be easily damaged during the process of extraction.

Most jacks rely on ball valves and sealing o rings to work and hold pressure. If the jacks continue to work at high temperatures, over time, the sealing rings are also very easy to age and cause oil leakage. After dozens of insulator tested, a high-strength wood material was finally selected.

Regarding the PID Temp controller, we have also done a lot of practices. It is necessary to ensure that the PID controller, thermocouple and relay are matched with each other to guarantee uniform, rapid and accurate heat transfer.

To be honest, although products have undergone very strict quality control before shipping, but unprofessional delivery may sometimes still lead to product defects. To this end, we must ensure that the parts of machine can be replaced to improve service life.

Rositek is an unknown small factory, born to solve customer pain points, we focus, persist, attentively, care about customers' buying experience, quality and customer service are our first priority. 

Rositek will be a game changer in the industrial!
