Automatic feeding, pressing, button feeding, button sewing and material receiving with continuous operation without intervals; Pre-feeding function to save time; One person can operate 2-3 machines at the same time; No skill requirement for operation |  |  |
A series of processes for placket buttonholing takes 24 seconds. One person can operate 3 machines at the same time, with each machine taking only 8 seconds. Compared with ordinary universal machines, it achieves more than 7 times higher production efficiency.
Return on Investment: Calculated based on an average monthly salary of 4,500 yuan per person, the annual savings can reach 4,500 × 12 × 6 = 324,000 yuan; while increasing output, it reduces the skill requirements for operators, greatly saving costs.
