For the first time in Asia, the WITTMANN Group presents an injection molding machine－the all-electric EcoPrimus－from now on is being produced at the company's own facility in China. With three live machine exhibits and a comprehensive showcase of automation and auxiliary solutions, WITTMANN reaffirms its position as an innovative partner in the injection molding industry at CHINAPLAS 2026.

EcoPrimus producing functional key rings

Specifically designed for high-volume single-component compact injection molding, the new all-electric EcoPrimus injection molding machine boasts a clamping force of 1000 kN, delivering high precision, efficiency, and cost-effectiveness. During the exhibition, an EcoPrimus 100/350 demonstrates its exceptional performance by producing functional key rings made of PS.

The EcoPrimus features a robust and compact design that ensures easy operation. Like all current injection molding machine series from WITTMANN, it is equipped with the latest Unilog B8X machine control system.

In last December, WITTMANN inaugurated the expanded production facility in Kunshan, China. In addition to robots and auxiliaries, injection molding machines from the EcoPrimus Series will now be produced locally.

At CHINAPLAS 2026, the new all-electric EcoPrimus injection molding machine is presented in Asia for the first time.

EcoPower producing LSR sealing rings

Another live machine demonstration is the EcoPower 110/210 producing liquid silicone rubber (LSR) sealing rings in a 16-cavity mold with a single shot weight of 1.7 grams.

The all-electric EcoPower demonstrates precision, efficiency, and cleanliness. It achieves high injection speeds and high dynamics and enables extremely precise control. Servo direct drives and the use of braking energy using WITTMANN KERS technology reduce energy consumption to a minimum.

MicroPower producing vascular clips

Occupying just two square meters of production space, the MicroPower is ideal for molding small and micro parts. Its design allows the injection piston to reach the parting line of the mold, minimizing the mass cushion and significantly reducing the sprue. This results in higher material efficiency and improved quality consistency, as pressure is transferred over a very short flow path.

At the fairgrounds, a MicroPower 15/10 will produce vascular clips made of POM, with each part weighing only 0.003 g in a 4-cavity mold. The micro parts are demolded by an integrated vertically arranged SCARA robot and quality-checked by a camera within the self-contained work cell. The good parts are sorted and deposited by cavity.

The work cell is equipped with a laminar flow box to ensure production under Class 7 cleanroom conditions in accordance with ISO 14644-1.

Primus robot with increased load capacity

In the area of automation, WITTMANN’s new Primus 118 makes its Asian premiere. This linear robot expands the range of applications for injection molding machines with clamping forces of up to 250 tons. While the maximum payload in this size range was previously five kilograms, the Primus 118 now offers a maximum payload of up to eight kilograms.

A new design featuring reinforced demolding and vertical axes, along with strengthened drives, enhances the high performance of the Primus 118. The robot accommodates up to ten valve slots, allowing for various combinations of gripper and vacuum circuits, with the capability of supporting up to eight vacuum circuits.

The Primus 118 operates with WITTMANN's proven R9 robot controller, which includes an OPC UA interface as standard for seamless data exchange with an MES and for editing and saving programs on a PC.

Temperature control units and granulators

In the exhibition area for auxiliaries, WITTMANN displays a range of equipment, including temperature control units, water flow regulators, dryers, vacuum loaders, and granulators for in-house recycling.

The temperature control units from the Tempro basic series are suitable for applications that require precise temperature regulation and high operational comfort while focusing on the essentials. The new size 120 has been developed specifically for large consumers.

The G-Max XL granulator demonstrates how easily valuable raw materials can be obtained from sprues and production waste. The compact granulators in the G-Max series are suitable for processing soft to medium-hard plastics such as PP, PE, ABS, PU, and PC.

The G-Max XL model showcased at the exhibition is the largest in the series, designed for a throughput of up to 100 kilograms per hour.
