Quick Selection Guidance

If the customer focuses on...	Better Fit
Stronger shearing force	QSW-800
Larger feed opening width	QSW-800
Larger structural steel / profile scrap range	QSW-800
Lower installed power requirement	QSW-630
Higher listed hourly output in the quotation sheet	QSW-630
More compact machine size	QSW-630
Heavier and larger scrap sections	QSW-800
Medium-to-heavy scrap processing with lower power footprint	QSW-630

Simple Recommendation Sentence for Customer Use

QSW-800 is generally the better choice when the customer needs higher shearing force, a wider feed opening, and stronger capacity for larger structural scrap sections.
QSW-630 is generally the better choice when the customer wants a more compact machine with lower installed power and a higher listed hourly throughput in the supplier’s sheet.

Regardless, we are a very experienced manufacturer. If you have any concerns or doubts about model selection, please feel free to send us the scrap metal materials you need to shear, your expected output, and the difficult-to-handle materials you often encounter. We will help you select the most suitable model to ensure it properly meets your requirements.

Let me know if you would like to adjust the tone to be more formal or more persuasive.
