ハイサイクル成形

Mold closing/ opening, hydraulic core, and tie-bar nut movement are all performed at high speed.

High speed filling is possible through the use of PLP (Peakless Pressure Control).

Cooling time can be reduced due to the uniform low temperature plasticizing performance of the UB screw.

Lap circuit capability (the mold can be opened while plasticizing and the ejector can be moved while mold opening).

Composite movement (lap circuit) and high-speed performance for cycle time reduction.

Highly accurated drive with economical motion.●Time lost can be cut in half due to the simultaneous actuation of the split nuts (compared with MITSUBISHI'S regular machine.)●Due to the innovative crank mechanism design, the speed of the split nuts can be reduced smoothly (eliminating the nut contact sound).

Dry cycle time can be shortened by more than 30%.●High-speed opening and closing motion ( 1.2 to 1.3 times faster compared with MITSUBISHI'S conventional machine)●Because of the accuracy of the clamp speed acceleration and deceleration control, "Zero" setting is possible for clamp slowdown areas.●Core actuation times are shorter because of the ample supply of hydraulic oil for the cores.

ハイサイクル成形

Cooling time can be shortened due to the uniform low temperature plasticizing performance of the UB screw .●Uniform low temperature plasticizing is possible because of the tapered dam clearance and long barrier flight.●High kneading, high plasticizing capacity and less energy used during plasticizing all provide for the superior performance of the UB screw.

High-speed filling and low-pressure injection is possible. Before transition to hold pressure, the filling pressure peak control“PEAKLESS PRESSURE CONTROL”(PLP) is adopted to automatically control the injection speed function.PEAKLESS PRESSURE CONTROLThe deceleration of the Injection speed is controlled from a position (set automatically) in front of the V/P change-over point for smoothly connecting the filling pressure load to the holding pressure setting pattern.EFFECTThe electric injection molding machine with servo control can easily build up peak pressure at the holding pressure change over position so the pressure wave shape will potentially be uneven. However, with the peakless pressure control system, the internal pressure of the mold can be kept at a low value because the peak pressure is controlled, thus providing a smooth pressure wave .HIGH SPEED INJECTION

With high speed injection, resin pressure inside the mold will be lower.

Complete protection for valuable molds ●Long platen supports are adopted to resist tilting and ensure parallelism of the moving platen and mold.●Linear motion guides with low frictional characteristics protect the mold with high sensitivity.●Waterproof telescoping covers protect the linear rails from contamination and help to maintain their accuracy.

●Clamp force is not influenced by changes in mold temperature so molding can be performed with even clamping force applied at all times.●Even in unbalanced mold conditions (ex. Offset mold), the mechanical structure of the clamp is not affected and a high degree of parallel accuracy is maintained.●A highly rigid, cross-rib construction platen design is adopted.

Clamping force is applied at four points for even application of mold clamping force.

Accurate positioning for "zero" take-out robot chuck errors●Superior accuracy of the mold closing and opening position control.●At the maximum high-speed setting, the mold open stop position is very stable and repeatable therefore chucking errors of the take out robot are eliminated.

Linear guide response to heavy loading conditions●The platen movement linear guides have a projected long life proven through the application of digital mock-up structure analysis and accelerated component durability testing.

Expanded molding features●The mold clamping pressure can be controlled by a two-stage clamp program, with low pressure and high-pressure stages, so that it can be used for injection compression molding applications.●It can effectively protect against sink marks and warping in the molded part by allowing gas to escape from the cavity.

An alarm indicator is displayed when a fault occurs. A “Current alarm screen” and “Detail alarm screen ” are displayed by touching the alarm indicator.

An NG screen indicator is shown when the relationships of settting values are not coordinated. The screen will show the area that has the NG setting value when the “NG screen indicator” is touched.

Direct path to main screens Direct setting

Direct buttons to switch to the four primary screens (temperature, mold opening/ closing, injection, plasticizing performance) are placed at the bottom of the screen, thus eliminating complicated screen change operations.

By touching the button of your choice, direct setting of values is possible. This eliminates the need for operating troublesome cursor keys.

Effective reduction in energy consumption is the same as an all electric injection molding machine.●Because of the inverter control of the eco-servo pump, the most suitable hydraulic flow can be applied for saving energy and maximizing the machine efficiency.●During the braking phase of the servo motor operation, power is recycled back to the source by the servo amplifiers.

The life of the ball screw is extended by the use of our patent pending load balance control system. ●The system features a dual ball nut design that detects the actual injection pressure and applies hydraulic pressure to the front ball nut so that the front nut and the rear nut loads are shared thus equalizing and distributing the forces applied to the ball screw.

●During closing, the clamp will stop just before it's fully closed position and injection will begin. At this time, the clamp cyliders are blocked to maintain the position. At a programmable time during injection, the clamp pressure is built up to complete the compression process.The injection compression process is effective for eliminating warping in thin wall molded parts and it is also effective for fabric-insert molded parts.

●Processing with long fiber filled resins is possible with less cutting, or breakage, of the glass-fibers.
