630 Ton Scrap Metal Shear: The Two-Shift Rhythm
A 630-ton machine on continuous HMS is a production line with a maintenance window. The rhythm that holds the published tonnage, shift by shift.

Continuous HMS 1 & 2 is a daily diet, not an occasional bite. The 630 ton class is where our range starts taking that duty seriously — here is the watershed.
Two yards buy the same 500 ton shear; a year later one holds its cycle time and the other has a repair history. The difference is what arrives at the box.
Ask for a 500-ton shear and you get a question back: which 500? Two genuinely different machines live in this class, and the split is material, not marketing.
Plate and section reward discipline and punish lazy charging. How both materials behave at the blade on a 400 ton class, and the routine that holds cycle time.
For dealers and processors the shear is not production equipment — it is margin equipment. The trading math that justifies the 400 ton class.
Tonnage pride pushes up and budget pulls down, but the heavy tail of your material distribution decides. A side-by-side of the three classes and the method to choose.
Mixed intake defeats undersized machines and overpays oversized ones. The 315 ton class sits in the middle for a reason — here is the sizing logic.
Every number on a shear datasheet is true and none of it tells you what the machine does on your feed. A row-by-row reading of the Q91-200 sheet.
A 200 ton gantry shear has precise boundaries: rebar, light sections and plate under 30 mm as a daily diet, HMS occasionally, heavy sections never. Here is the full map.
