High-Speed All-Electric Machine Line Launches


Korea’s LS Mtron will introduce the ONE*-E series with five sizes—120, 140, 190, 310, and 390 tons—with plans to introduce four more models later this year.


LS Mtron (U.S. offices Peachtree Corners, Ga.) will introduce the ONE*-E line of all-electric injection molding machines at Plastec West (Anaheim, Calif.; April 12-14) in the Hirate America booth. 

The ONE*-E is a new, all-electric injection molding machine from LS Mtron that features a new toggle-link design for fast, best-in-class speeds (1.49 second dry cycle times). 

The ONE*-E will launch in the U.S. with five sizes of 120, 140, 190, 310, and 390 tons, with plans to introduce four more models later in 2022. 

The company says the machines are suited for  high-cavitation, high-speed, and thinwall molding typical in packaging and medical applications. 

The machines utilize a new optimized toggle for fast cycles and precision molding, according to LS Mtron. 

Specifically the company says the new toggle design allows a 30% faster link-speed ratio and a dry-cycle time of just 1.49 seconds. In addition, the ONE*-E features an overall smaller footprint compared to existing ONE*-E’s, shrinking from 5453 by 1499 by 1853 mm (approx. 215 by 59 by 74 in.) to 5281 by 1495 by 1800 mm (208 by 59 by 71 in.).

Constructed from a rigid, one-piece casting, the ONE*-E offeres reduced vibration while shortening the injection acceleration time for thinwall molding by almost 4 times, according to LS Mtron, from 78 ms to 20 ms. The company says the rigid construction and a low-inertia design also reduced rotator inertia by 74%. 

The machine’s control features a 18.5-in. touchscreen as standard, with a 21.5-in. option that gives users swipe, pinch and zoom functionality. It also offers users LS Mtron’s CSI monitoring and control software for retrieving and controlling data, using a next-generation dual-core CPU. 

The CPU structure allows the machine’s control to separate the architecture into main and HMI CPUs. This allows it to improve load times and offer additional modes, including clamp-force optimization mode; clamping high-speed low-vibration profile mode; high-speed injection mode; packing (or holding) pressure pattern selection mode; and residual pressure elimination mode in case of charging completion.

In addition to automatic weight control software, the ONE*-E can monitor clamp force via a tie bar sensor to automatically calibrate closing force. 

There is also an automatic zero-point adjustment mode for a spring mold. The machine’s dual center press die structure minimizes the platen deformation while also better distributing surface pressure in the mold, helping to extend tool life.  

Digital load cells improve measurement control and process reproducibility. Specifically, the company says it allows minimized deviation through precise injection pressure and charging control; increased servo motor encoder resolution from 17 bits to 20 bits; enhanced response performance to the drive control frequency by 3.7 times; and faster Ethernet communication by 2 times.



The ONE*-E line of all-electric injection molding machines will debut in the U.S. with five tonnages.
