Chinese manufacturer Tederic Machinery unveiled at K 2025 its new Innova 250 high-speed hybrid injection molding machine designed for the packaging industry.
A joint Chinese and German team spent four years developing the new series, according to Daniel Ammer, VP for research and development at PlastiVation Machinery GmbH in Munich, a mechanical engineering company that is Tederic’s partner in Europe.
“With its electro-hydraulic hybrid drive, Innova offers substantial advantages, especially for packaging applications, and ensures efficient production and significantly reduces energy consumption,” Ammer said when he introduced the new press. “Its robust mechanics ensure high performance and extend the service life of the machine and tools.
“I think this is the perfect combination of speed and performance.”
Ammer said the series features an efficient plasticizing system and a new screw design to ensure high throughput and homogeneous melt.
The accumulator-assisted, closed-loop injection system has a speed of 700mm per second. At K 2025, the machine, with 250 tons of clamping force, was producing HDPE bottle caps weighing 1.25 grams in a 24-cavity mold with a 2.9-second cycle time.
The toggle-style clamping and plasticizing units are electric, and an energy-recovery braking system is standard. The toggle has a closed-loop lubrication system.
Space between the tie bars is 650mm by 650mm. The maximum daylight is 1,320mm. The screw diameter is 50mm.
Ammer said the control interface is designed to be user-friendly. Keba built the controller.
Tederic has not yet announced the other sizes it plans to offer, but Ammer said the Innova series would go up to 650 tons of clamping force.
In addition to showcasing the new press, Tederic demonstrated its ability to furnish automated, turnkey cells with two different applications.
The first was an automotive application built around a NEO M1420v multicomponent molding machine with a vertical rotary table, two parallel injection units and a Tederic robot. Controls for the injection machine and auxiliaries were integrated along with real-time monitoring. The cell used the company’s trademarked MultiMold process to produce high-gloss, automotive exterior plastic D-Pillar panels. Cycle time was 70 seconds.
The second turnkey cell used a hybrid NEO H100ultraX two-platen injection molding machine with a 2+2 cavity mold to produce a 3.7-gallon round PP bucket. Cycle time was 14 seconds. The cell also featured in-mold labeling (IML) and automated stacking.
Tederic’s headquarters and primary manufacturing facilities are in Hangzhou, China. Tederic machines are sold in 140 countries, according to the company.
