Press for making a part from fiber composite

A press for making a part from fiber composite, the press comprising:

• a laterally open C-shaped frame having a n horizontal upper C-leg, a horizontal lower C-leg, and a vertical C-base extending between the upper and lower C-legs;
• a mold;
• a lower element on the lower C-leg and supporting the mold;
• a upper element on the upper C-leg and having a pressure case that can be sealed against the lower element;
• press cylinders supported on the frame and acting on the upper element or on the lower element;
• a membrane stretchable over or against the mold;
• a vacuum pump applying subatmospheric pressure on a side of the membrane turned toward the mold;
• a superatmospheric pressure pump applying superatmospheric pressure in the pressure case on an opposite side of the membrane turned away from the mold;
• and
• means for heating an interior of the pressure case on the opposite side of the membrane or for heating the mold.
