Levers are your friends: a lever allows you to multiply up the force of your own strength. Here's a manual can crusher, demonstrating this: source Your hand moves three or four times the distance that the crushing part does; as a result, the crushing part moves with three or four times the force that your hand does.

The blades are indeed made of, or tipped with a hard steel/carbide, but they also don't contact each other. The shredding action is created by the shear forces of the two corotating drums of "teeth", and this non-contact between the hard points, high shear strength, and gearing advantages allow it to power through whatever you throw at it. https://www....

A bench press or arbor press, combined with a suitable die for horizontal containment, will allow you to produce rather high forces and pressures. Do you have any numbers — volume, pressure, etc. — regarding exactly what it is you're trying to achieve? EDIT: I have to confess that I missed the waste-disposal tag on my first reading, so my first ...

if you cut the drum longitudinally into two half-cylinders you will have 10 cut ropes with a tension of 200kN. Let's say the center to center distance of each rope is L inches (moderately small WRT. to the radius) then you have to calculate the area of the section of the barrel between the ropes and a thickness,t, and a safety factor of 1.6 1.6*200kN/(L*t)&...

I'm not clear from your question if you are trying to crush a plastic object, or manipulate hot plastic (eg for injection molding.) Lever systems are certainly a good option as has been mentioned in other posts, but depending on your application, a compact lever may not provide enough force for you.. If you need more force, hand-pumped hydraulic jacks will ...
