Detailed Description

YJ 71 series plastic forming presses,Press forming of plastic products can be classified into thermosetting material forming and thermoplastic material forming. For example, bakelite of electric appliance industry. And also polyfluortetra ethylene plastic in consumer goods industry. You can change the controlling program to carry out press forming to the friction materials. For example, brake pad. 　　This series of plastic products hydropress material machine uses integrated system of inserting mounting valve. The electric appliance uses PLC programmable controller. The pressing action can be separated into rapid down of sliding block, descending with reduced speed,slow press forming pressure maintenance (sometimes air discharging is needed),pressure releasing, slow return of sliding block, rapid retuming to upper limit, rapid ejecting of ejection cylinder,returning of ejection cylinder,manual material taking and adding ,pressing machine has high and low pressure combination pump.In case of rapid ascending, oil adding can be realized by descending with self weight. Through this, the power needed in the rapid stage is greatly decreased. In case of rapid pre-pressing forming, the high and low pressure pumps both take part in the action.When the pressure reaches a definite value or pressed to a definite position, the low pressure pump releases the pressure and only high pressure pump works. Thus forms the low speed press forming and it sconvenient for the full flow of the material and discharge of gas out of the cavity. The main units of this series of hydropress has excellent configuration and this greatly increased the reliability of the products.For example hydraulic pressure parts use the products made by Beijing hydraulic pressure part factory, the thermal couple is also famous brand produt. 　　Our company can increase the width and height of the special press according to the requirement of the user.
