1. A rosin press apparatus configured to extract rosin from a plant material, the apparatus comprising:
a frame having a first side plate, a second side plate, a top end support box, a bottom end support box, and a support plate located between the top and bottom end support boxes,
wherein the top end support box comprises a first cross plate and a second cross plate, the first and second cross plates being interdigitated with the first and second side plates at top corners of the frame, an intermediate plate positioned between the first and second cross plates, a transverse plate positioned between the first and second side plates, an upper plate positioned below the transverse plate and the intermediate plate, and an addition plate positioned above the upper plate, and
wherein the bottom end support box comprises a third cross plate and a fourth cross plate, the third and fourth cross plates being interdigitated with the first and second side plates at bottom corners of the frame, an intermediate plate positioned between the third and fourth cross plates, a transverse plate positioned between the first and second side plates, a base plate positioned above the transverse plate and the intermediate plate, and an additional plate positioned below the base plate;
a hydraulic press connected to the frame;
a first press plate connected to the press;
a second press plate connected to an underside of the upper plate of the top end support box of the frame and oriented above the first press plate; and
a heating element configured to heat at least one of the first and second press plates;
the press being configured to drive the first press plate toward the second press plate, thereby applying pressure to the plant material positioned between the first and second press plates and wherein the frame is configured to inhibit flexing during such application of pressure.
