Nissei Plastic Industrial Co. (Nagano, Japan) offers processors a total of 19 machine configurations in its all-new TNX Series of hybrid vertical-injection molding machines debuting this month.
The TNX Series of turntable machines offers five models based on clamping forces ranging from 50 tons to 220 tons, with either center injection (vertical injection from top of the mold; TNX-R-V variant) or parting line injection (horizontal injection from side of the mold; TNX-R-A variant) available. The parting line option is made to order.
The TNX Series employs Nissei's super energy-efficient hybrid X Pump system, consuming 70% less power and 25% less hydraulic oil than a conventional hydraulic machine in the case of the 50 ton TNX50R. This unit boasts maximum injection velocity: 300 mm/sec (2.6-times faster than conventional hydraulic machines) and an injection response time of 60 msec (twice as fast as conventional hydraulic machines).
Its servomotor-driven pump permits low-flow volume control, and feedback control is capable of precisely controlling the velocity setting below 1 mm/sec. In addition, controllability and stability in the ultra-low pressure range have been improved significantly, which are ideal for thick-wall product and hot melt (low-pressure encapsulation) moldings, according to Nissei.
The TNX Series is equipped with a three-tiebar-wide turntable, and the maximum mold dimensions mountable are said to be the largest in industry (up to 20% larger than predecessors). Nissei has sold about 10,000 vertical injection molding machines in its history and plans to target annual sales of 150 units for TNX machines. Target applications include tactile switches for electrical/electronic parts, narrow pitch connectors for mobile devices, mesh filters for automobiles and LED bases and reflectors. —[email protected]
