The choice depends on your production volume. Manual machines are cost-effective for startups or low-volume customization, with a typical output of 200-300 pieces per hour. Pneumatic machines, which require an external air compressor, are ideal for medium-sized factories, increasing efficiency to 500-800 pieces per hour while reducing operator fatigue. Fully electric/automatic machines represent the highest investment but offer the best ROI for mass production, capable of producing over 1,200 pieces per hour with minimal labor costs.
