•  
• Paste pump: Stainless steel pump body, equipped with manual and automatic control type, Level control through paste liquid feeler lever and PLC.

Main drive system of printing conduction band:

CAN technology and 485 communication, underlying data centralized processed in upper computer, speed control mode and control each screen head servo motor, achieve printing synchronous to keep sure printing efficiency. All the information showed to customers through human-computer interface, convenient to operate and manage. This system is reliable under condition of high temperature,high humidity,strong corrosion,strong interference.

Screen head independent drive:

1. Servo motor can control high precision registeration of rotary screen in circle of 360°,accumulated error code difference is within 0.08mm.Controller of main operation panel can change add to interchange convenient and directly.
2. High performance transducer process encoder speed closed-loop control. Other transmission motor uses universal converter; transform the analog quantity type into digital quantity type system to ensure system synchro control precision.

Electronical control of handpiece internal: Printing units equipped with independent servo motor, advanced AC servo driver, each unit equipped width prefab cable connector, through optical fiber communication to keep sure printing precision of printer, Electrical system is very easy for maintenance.

Main junction box: used for voltage control, circuit distribution, chamber temperature control etc.

Operation and monitoring system: touch screen centralized control(in addition equipped with one set of button control together with touch screen);machine speed,output,stoppage and technological parameter etc. centralized display; touch screen can also provide parameter set of  register speed,register parameter,inserting precision,synchronous factor ,convenient for clients to design and modify according to products request.
