Heating system: TN380C adopts high effective and energy-saving
Nickel-chromium heating tube. Advanced technology and Long life. And
TORCH self-developed hot-air circling system features warm up quickly, which
Can make PCB component be heated evenly.
Protection system: TN380C uses SSR solid relay (450V) that has large
Power and pressure prevention to non-contact output, safe and reliable. It can
Monitor the change of temperature and heat number in furnace chamber with the
Functions fuzzy control and data collection. Then control the heating component
With the least pulse and response quickly. TO keeps the Temperature control
Accuracy, but the equipment can not be damage for the high current and high
Voltage. And each room fits a safety pipe which is high temperature and high
Pressure resistant function so that the whole system can run safely and calmly.
Accuracy control by IPC and PID intelligent arithmetic. According to the PID intelligent calculation, heat output can be controlled accurately and response
To the change of outside to balance the temperature. The whole system has a
Modularized design. It is convenient to maintenance and disassembles
Outer shell and furnace body of TN380C can be opened wholly and automatically. It is convenient to clean and maintain it.
[Main features for TN380C]:
1> Intuitional welding control: TN380C adopts advanced furnace
Temperature collection system. It can test temperature curve and temperature in
Furnace hearth. The temperature curve can be recorded or printed at the same
Time.
2> Smooth and safe transmission system: Drive system adopts a high
Quality conversion motor and conversion system. It also has a closed-loop
Governor and Turbine speed reducing box of 1: 100 to keep running
Smoothly. Speed: 01600mm/min.
3> Stable and safe electric control system: Delay switch protection. After
Power off, temperature drops evenly so that can prevent damage to transmission
Component and heater.
4> Power-off protection: To keep PCB output normal. Windows operating
Platform has a strong functions and high stability.
5> Upper and lower heating zones are separately controlled. The circulation speed can also adjust separately. It is suitable for welding different
PCB plates and components.

1 Advantages and characteristics of multi-layer co-extrusion cast film production line
| This production line can produce CPE, CPP, EVA, PETG, PVC, PES transparent, textured and breathable films.
| The screw is designed with special mixing function and high plasticizing capacity, combined with a special static mixer to ensure good plasticizing, good mixing effect and high output.
Jingcheng automatic adjustment die head and French Skender automatic thickness gauge can be selected to automatically detect film thickness online and automatically adjust die head.
|Large-diameter forming rollers and special spiral channel design ensure good film cooling and shaping effects at high speeds.
| Equipped with a negative pressure device to ensure the stability of the film melt film.
1 Film scraps are directly recycled online, greatly reducing production costs.
1. The drive of the whole machine is driven by a servo motor, and the constant torque ensures stable and efficient operation.
|Screw power adopts permanent magnet motor to save 20% of electricity.
I multi-co-extrusion design can flexibly adjust the formula to reduce costs on the premise of ensuring product quality and functionality
The configuration is flexible and changeable, tailored according to the actual needs of customers, and the cost performance is maximized.
