16 smart_molding interna onal 1/2026 CHINAPLAS 2026 WITTMANN at Chinaplas 2026 in Shanghai At Chinaplas 2026, the WITTMANN Group is se ng a milestone. For the rst me, an injec on 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 e ciency with very high cost-e ec veness. With a total of three live machine exhibits and a comprehensive presenta on of auxiliaries and automa on solu ons, WITTMANN will be presen ng itself as an innova ve partner to the injec on molding industry at Chinaplas 2026 from April 21 to 24 in Shanghai, China. EcoPrimus: Focused on the essen als 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 e ciency 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. At Chinaplas 2026, the new all-electric EcoPrimus injection molding machine will be presented in Asia for the first time.
