Equipment Description：

This series of flat vulcanizing machine is the main equipment that can be used in pressing all kinds of rubber model product and non-model product. In addition, it also can be used in pressing all kinds of thermosetting plastic and foaming rubber and plastic product. With independent actuating unit and electric system, apply button centralized control. Within certain limits, working pressure and heating temperature can be adjusted. This kind of model, can be classified manual operate and semi-automatic operate. The flat vulcanizing machine with the function of a high degree of automation, easy operation,energy conservation and environment protection, and also superior performance.

Main Features：

1.Controlled by PC or manual, performance reliable, high degree of automation. Can automatically identify the wrong command,so avoid the accidence which caused by wrong operation.

2.The preprogrammed process can be locked, the operator can not change without authorization, so that guarantee the quality of pressed product.

3.With the function of timing open mold, automatically exhaust and reinforcing pressure,etc.

4.Optional: Manual operating or Automatic operating mode

5.Electrical heating pressing machine apply digital display（or pointed type) to control temperature, and control and display the heating plate temperature.

Application： 

   It mainly used in producing vulcanizing parallel adhesive type, such as conveyor belt,driving belt, and pressing rubber products, foamed plastic,thermosetting plastic(bakelite) and other plastic products. It also suitable for O ring,the key products such as cell phone, keyboard,remote-control,sealing washer such as pressure cooker, electric cooker, mechanical accessories for household, food, health and medical treatment. At the same time,this machine alsocan be used in complex silicone and rubber fittings production and process, such as nipple,medical supplies, health product, artware, toy seal, electroconductive rubber, automotive rubber parts, industrial rubber parts,medical silicone product, sport equipment, all kinds of vessels, multilayer product and so on.

Introduction：

Flat vulcanizing machine is mainly used in vulcanizing flat belt(such as conveyor belt,driving belt). It is a kind of hydraulic machine. The main function of flat vulcanizing machine is providing the pressure and temperature for vulcanization. The pressure is generated from hydraulic system by hydraulic cylinder, and the temperature provided by heating tube. The control part of flat vulcanizing machine is mainly consist of high and low pump motor on hydraulic station,magnetic valve,vulcanization time,motion instructions and alarm function, etc.

Technical parameter：

1.The system including two kinds of operating mode: automatical and manual.

2.During manual running: Turn on opening mold, stop opening mold, turn on clamping mold, stop clamping mode by pressing button, to finish the manual control for opening and clamping mold.

3.Automatically operating process showed as below。Solenoid valve, and others are vulcanizing time,motion instruction and alarms, etc.

• Action execution instruction：

a）The process of clamping mold is finished by two low pressure(11KW) pumps and a high pressure(18KW) pump, the hydraulic system drives the lower mold to do the upward movement,when the pressure achieve to the low pressure limit(12MPa), the low pressure pump will stop; When achieving high pressure limit, the high pressure pump will stop, and the whole process finished.

b）During holding pressure, due to use check valve in the hydraulic circuit, so no need to the hydraulic pump work, and keep the pressure of hydraulic system, the holding pressure process finished after 10s.

c）The slow pressure process consist of open mold motor(2.2KW), open mold solenoid valve and high pressure pump. When access to slow pressure step, firstly, the open mold motor and open mold solenoid valve will finish decompression. When the pressure achieve to 0 Mpa, the opening mold motor and open mold solenoid valve will be outage,the high pressure pump will power on and clamp force, when achieve high pressure limit, the high pressure pump will stop and repeat three times, then slow pressure process done.

d）After slow pressure process, access into vulcanizing stage. Similar with holding pressure, but due to longer time(30~45min, different material will be different, time adjustable), the pressure will drop, when the pressure lower than pressure limit limit(16Mpa), will ask for turn on high pressure pump to reinforce pressure until the pressure up to high pressure limit.

e）Open mold is finished by open mold motor, open mold solenoid valve. When the lower mold drop to start position( Controlled by open mold in place stroke switch), the open mold done.

5）Vulcanizing temperature is provided by steam, the boiler produce steam, then access to vulcanizing machine uninterruptedly by manual valve.

6）System setting includes total stop button, open mold instruction button, clamp mold instruction button, vulcanization finish alarm button, and the necessary protect device such as short circuit and overload, etc.
