1. Advantages and disadvantages of mechanical type:
1. The speed of mechanical type is fast
2. The stroke is accurate and will not change after adjusting the die spacing
3. The up and down stroke can not be adjusted e to the mechanical driving of rotating crankshaft
4. Because it is pure mechanical type, there is no pressure protection, if it is not adjusted properly, It is easy to damage the machine or mould.
advantages and disadvantages of the hydraulic press:
1. The speed of the machine is much slower than that of the machine.
2. It is difficult to accurately locate the bottom dead center by means of the travel switch or the oil pressure, etc. besides using the hard cushion.
3. The distance between the up and down travel can be adjusted at will.
4, It won't damage the equipment and mould
5. Compared with the mechanical type, the noise is less
for the time being, I only think so much, other netizens will add
