Leader Non Woven Box Bag Making Machine Comparison
No | Item | MACHINERY | OTHER SUPPLIER |
1 | Industry character | Professional focus on non woven bag making industry, with R & D and innovation | Variety business, as plastic package, cover lots of other business |
2 | History | We keep R & D for four years, Leader has been sold since 2013 about five years | Imitation, sales less than three year |
3 | Market share | >80% | <20% |
4 | Machine Weight | 12Ton | 4-6Ton |
5 | Steel cutting and welding | Sawing machine: smooth incisions, standard angle. | Ordinary abrasive cutting off machine. |
Standard welding platform:Guaranteed The levelness and verticality of steel welding | No standard welding platform. Welding free on the ground, Frame deformed easily. | ||
6 | Parts processing technology | Three-dimensional five-NC machine tools: high precision, high quality. We regard precision and quality as the standard. Seriously deal with each processing accessories. (Example: 1. Heidelberg screws 2. What is three-dimensional five-sided processing) | On the outside processing, with the most common pain plus vertical processing machine, do not pay attention to quality and precision, to efficiency. |
7 | Left and right large board | Board thickness is 4cm, the machine running stable under high-speed producing. | Relatively thin, Production instability (one aspect) |
8 | Side insert board | Single castling, levelness is very good, producing steady, Easy adjust | Use screw to joint the parts, easy inclined, Not at right position, producing not steady, bag mouth not at same level |
9 | Electrical | 11 sets servo motor, 33 sets stepping motors,safe and steady, Long working life | Normal China made servo motor & stepping motor, cylinders low quality |
10 | Controller | Trio motion controller with PLC combined, double protection, Signal is not disturbed, Safe and steady, long service life | Only PLC control, easy to be to be distracted, not safe |
11 | Guide rail + Mould | Low noise,energy saving.Adopt smart mould save time for changing mould and save money | Normal mould, long time for changing mould, high cost of mould, Customize mould need time,can not use in time |
12 | Ultrasonic | Our Own brand Ultrasonic, 72 hours running test, quality guaranty, after sales service in time | They purchase Ultrasonic from other company, don't have their own brand ultrasonic. Quality and after-sales service can not be guaranteed。 |
13 | Touchscreen control system | Get ability to analyze production data,such as machine stop reason,etc. | Normal display system |
14 | EPC system | 3 EPC system | 1-2 EPC system |
15 | Intelligence level | Machine adopt more intelligent design to operation more conveniently. Reduce the time when you change bag size and save more time for produce | It is high dependent on the worker’s operation skill, experience and good eyes. Need more time for operation when change the bag side, and waste more material cost and time cost. |
