At Chinaplas 2026, the WITTMANN Group is setting a milestone. For the first time, an injection molding machine will be presented that from now on is being produced at the company's own facility in China. The all-electric EcoPrimus combines precision and efficiency with very high cost-effectiveness. With a total of three live machine exhibits and a comprehensive presentation of auxiliaries and automation solutions, WITTMANN will be presenting itself as an innovative partner to the injection molding industry at Chinaplas 2026 from April 21 to 24 in Shanghai, China.

EcoPrimus: Focused on the essentials
The EcoPrimus, with a clamping force of 1000 kN, was specifically developed for high-volume single-component compact injection molding. Here, the new all-electric injection molding machine combines high precision, efficiency, and cost-effectiveness. It features a robust and compact design, and users do not have to compromise on ease of operation. Like all other current injection molding machine series from the WITTMANN Group, the EcoPrimus is equipped with the latest Unilog B8X machine control system. At Chinaplas, an EcoPrimus 100/350 demonstrates its high performance with the production of functional key rings made of PS.
EcoPower: Precision and efficiency for LSR
Also the second live machine exhibit demonstrates the efficiency of WITTMANN's all-electric injection molding machine technology. An EcoPower 110/210 is used to produce liquid silicone rubber (LSR) sealing rings in a 16-cavity mold with a single shot weight of 1.7 grams. Worldwide, applications involving silicone are becoming increasingly important. This trend is being driven by modern medical technology on the one hand and electromobility on the other. Both industries exploit the outstanding range of properties offered by LSR. Components made of liquid silicone can be used in a particularly wide temperature range from -50 to +250 °C. They have good electrical insulation properties, very good weather and aging resistance, and high biocompatibility.

MicroPower: Everything it needs on a minimum footprint
Everything it needs for production in just two square meters – that's what the unique MicroPower concept offers for molding small and micro parts. The design of the machine allows the injection piston to reach the parting line of the mold. This reduces the mass cushion to a minimum and significantly reduces the sprue, if not eliminating it altogether. The result is higher material efficiency and improved quality consistency, as the pressure is transferred over a very short flow path.
During Chinaplas, a MicroPower 15/10 produces vascular clips made of POM with a single part weight of 0.003 g in a 4-cavity mold. The micro parts are demolded by the integrated vertically arranged scara robot and quality-checked by camera within the self-contained work cell. The good parts are deposited sorted by cavity. The work cell is equipped with a laminar flow box to ensure production under Class 7 clean room conditions in accordance with 14644-1.

Primus robot with increased load capacity
In the area of automation, WITTMANN will be presenting an Asian premiere at Chinaplas 2026. The new Primus 118 expands the range of applications for Primus linear robots for injection molding machines with clamping forces of up to 250 tons. Whereas the maximum payload in this size range was previously five kilograms, the new robot offers a maximum payload of up to eight kilograms. A new design with reinforced demolding and vertical axes as well as reinforced drives underpin the high performance of the Primus 118. The robot offers up to ten valve slots and thus various combinations of gripper and vacuum circuits. Up to eight vacuum circuits are possible.
Tempro basic 120: Precise control with ease of use
In the auxiliaries exhibition area, several representatives from all product categories are on display live in Shanghai: temperature control units and water flow regulators, dryers and vacuum loaders, as well as granulators for in-house recycling.
These include, for example, temperature control units from the Tempro basic series. They are the cost-efficient choice for all applications which require precise temperature regulation and high operating comfort and still concentrate on the essentials. The new size 120 was developed specifically for large consumers.

G-Max XL granulator for clean, homogeneous regrind
During the four days of the trade fair, a G-Max XL granulator will be demonstrating how little it takes to obtain valuable raw material from sprues and production waste. The compact granulators of the G-Max series are suitable for soft to medium-hard plastics such as PP, PE, ABS, PU, or PC. The optimized rotor ensures clean, homogeneous regrind and high material throughput. The solid flywheel maximizes the inertia of the rotor to achieve significantly higher performance with the same energy input. With speeds of 200 rpm at 50 Hz, the number of unnecessary cutting repetitions is reduced. Thanks to the tiltable hopper, screen changes and cleaning can be carried out very easily without tools. The G-Max XL model presented at Chinaplas 2026 is the largest in the series. It is designed for a throughput of up to 100 kilograms per hour.
Complete solutions from a single source
When it comes to material handling, automation, injection molding machines and mold temperature control, in-house recycling, digital technologies, or complete solutions from a single source, WITTMANN is the reliable partner for all industries that require high-quality and affordable plastic products, such as packaging, medical technology, automotive, and household appliances. “Our expanded production facility in Kunshan represents WITTMANN's transformation from a single-unit supplier to a full-service total solution expert,” emphasizes Kevin Wang. “Here in China and Asia, we can now offer our customers integrated system solutions from a single source that are produced entirely locally.”
