A new mold clamping
mechanism “Flat Clamp”
... ideal for high-cycle/precision molding
 |
The newly designed movable and center-supported stationary platens, which
were developed by applying the structural analysis data, reduce the deflection
and ensure even distribution of clamping force. |
 |
Toggle pins, movable platen slide, and many other small parts of the sliding
section are made from high-rigid/high wear-resistant materials to maintain
high-precision mold opening/closing operation for a long time. |
 |
Major sliding sections are automatically greased. |

Automatic
clamping force adjustment: “Linear Pressure Toggle” made possible
 |
Automatically adjust clamping force deviation due to temperature change (common
in toggle machines) and distribute pressure evenly. |
 |
No need to stop the machine for clamping force readjustment. |
 |
Be able to set more optimal and minimal clamping force than previous series
because of its stable clamping force. |
 |
Since the clamping force is reliable and stable, it is easy to do measurements
for defectives, such as insufficient gas release, warpage, and weld. |
Effect of automatic clamping force adjustment
[Clamping force 500-kN: with automatic correction vs without automatic correction]
|
- Just like a direct-pressure molding machine, changing clamping force during continuous molding operation is possible.
- The clamping force is one of the most important factors in molding.
- This direct clamping force setting is highly effective for ECO- molding.

Shortened molding cycle
 |
Mold opening/closing operations and ejector operations become faster. |
 |
Simultaneous operations, such as mold opening/ejection during metering and
injection during mold clamping, can easily shorten the molding cycle. |

Wide Platen (square wide)
 |
The modern molds are becoming more complex and large. In order to cope with
this trend, we have extended the tie bar clearance to that of one-class larger
machines. It can mount not only a horizontally one-class larger mold, but also
a vertically over-sized one on to the machine. |

Further reinforced stationary and movable platens. |

Magnetic clamp, T-slot clamp, valve gate, and etc. can be installed
 |
A magnetic and T-slot clamp as well as thick molds, such as hot runner, deep
well, and split molds can be mounted. |
