Hybrid Type Vertical Injection Molding Machine (turntable Type)
TNX SERIES
TNX Series is a turntable type ideal for many types of insert moldings. TNX Series offers five basic types by clamping force, ranging from 532kN (50ton) to 2156kN (220ton). For injection, center-injection type (vertical injection from top of the mold) “TNX-R-V” or parting-injection type (horizontal injection from side of the mold) “TNX-R-A” can be chosen, offering optimal selections from 19 different configurations (parting injection types are made to order).
The key feature of “TNX Series” is its innovative super energy-efficient hybrid pump system “X-Pump,” which demonstrates superb injection performance while saving on the running cost.
For 50 ton TNX50R, it consumes 70% less power and 25% less hydraulic oil than those of conventional hydraulic machines.
Injection Mechanism
Simple & Compact Injection Mechanism that Materializes Outstanding Injection Performance
(1) Expanding moldable range by securing wide-ranging injection
By switching the discharge volume of a hydraulic pump whenever necessary to correspond to the molding conditions, it materializes outstanding controllability in wide-range of injection speed and pressure.
(2) Expanding moldable range by its outstanding stability in ultra-low speed & pressure range
Its servomotor-driven pump permits low-flow volume control, and the feedback control is capable in precisely controlling the "velocity setting below 1mm/s," which is impossible to achieve with the conventional hydraulic machines. In addition,
controllability and stability in ultra-low pressure range have been improved significantly, making it ideal for thick-wall product and hot melt (low-pressure encapsulation) moldings.
(3) Expanding moldable range and improving product quality by its long-sustainable high injection pressure
X-Pump equipped machines can perform "holding of high injection pressure for a long time," which is difficult to achieve with the electric machines.
Injection Performance of TNX50R5V:
Quicker injection speed and response time (injection rise time to reach the maximum velocity) materialized.
Clamping Mechanism
Long-Lasting Stable Operation of Direct Pressure Clamping Materialized
(1) Long-lasting stable operation by the "direct pressure type" clamping
It is equipped with a direct pressure type clamping mechanism, which is resistant to temperature change of the mold and clamping mechanism, generating consistent clamping force according to the setting. It is easy to set optimal (low) clamping force friendly to the mold & machine, and its simple and clean mechanism can maintain machine precision for a long time.
(2) Larger maximum mountable mold size
Wide turntable with 3-tie bar shaft is equipped, increasing the maximum mountable mold dimensions to the industry-best level (up to 20% larger than our conventional machines). It accommodates larger mold due to intricate shape of the products or mold with a slide core.
(3) Faster cycle by the servomotor drive
Turntable rotation and ejector motion are driven by servomotor. Faster-yet-smooth (low-vibration) rotation and simultaneous motion of injection/metering & ejection are possible, achieving faster cycle.
(4) Improved workability and operability
It offers a wide workspace around the turntable (mold mounting face). Its low-height turntable significantly improves preparatory work, such as mold change, and workability/operability of workpiece insert and product takeout. It can flexibly be adopted into automation systems, such as robots.
