When sourcing gas stove production equipment, you must prioritize hydraulic press capacity (tonnage) for deep-drawing the stove body, typically ranging from 100 to 500 tons depending on material thickness. Ensure the CNC punching and bending units offer a precision tolerance of ±0.1mm to guarantee airtight assembly. Additionally, verify the mold compatibility; high-quality machines should support quick-change mold systems to allow for different stove models (single vs. double burner) with minimal downtime.
