Application Field

Suitable for the production of thin wall molding items of engineering plastic such as mobile phone parts through high pressure and hign speed.
UCP I

- Thin wall precision molding through high pressure and high speed
- Mounting of wear-resistant screw and cylinder to cope with engineering plastic.
- Reduction of non-pressure and improvement of responsiveness through enhancement of accurate straight advance of screw and plasticization equipment
- Reduction of gas generation rate inside the cylinder through the improvement of mechanical structure and elimination of screw wearing phenomena due to distorted core.
- Stable molding through Closed-Loop
|
UCP II
- Improvement of the molding of thin wall products through the increase of injection pressure and injection speed
- Securing of repeatability and responsiveness by standard mounting of servo-valve for injection speed and pressure control
- Control of back pressure: Improvement of molding quality through the control by servo-valve
- Minimize inferiority rate of molding products by securing precision of control

Comparison of general proporation-valve and Servo-valve
|
|
Classification
|
General proportion valve
|
Servo-valve
|
Remarks
|
|
Response speed 100Bar rising time
|
60~80 msec
|
20~30 msec
|
Servo-valve is approximately 2.5 times Response is fast
|
|
Hysteresis Curve (Deviation rate of rising and lowering of pressure)
|
3%
|
Less than 0.1%
|
If there is big deviation in Hysteresis Curve, it influences to the change of pressure.
|
|
Repeated deviation (Change in pressure)
|
1%
|
Unable to measure(No change)
|
If there is big repeated deviation, the problem of repeatability will occur.
|
|
Temperature deviation (40℃ temperature transformation)
|
0.2mA per 1℃ Approximately 2.7%
|
1%
|
If there is big deviation depending on the changes in temperature, problem will occur in product molding.
|
|
Minimum basic pressure
|
7~14Bar
|
0Bar
|
The higher minimum basic pressure becomes, the more difficult low pressure control is.
|
|
Linear characteristics (Signal value of valve and actual pressure curve)
|
Curve (Different in change by section)
|
Straight line
|
Straight line: As all sections have uniform range of change, control is easy.
|
|
UCP II
- Realization of ultra-thin wall products through the increase of injection speed.
- Reduction of injection pressure by the improvement of initial responsiveness through Acc driving
- Improvement of repeatability and responsiveness by adopting CLOSED-LOOP controller - Stable molding of products
- Securing of repeatability and responsiveness by standard mounting of CLOSEDLOOP servo-valve
- Increase of energy savings effect according to the use of small size drive motor
