During the Swiss Plastics Expo 2026 from January 20 to 22 in Lucerne, Switzerland, the WITTMANN Group will be focusing on precision and efficiency. At its booth two live exhibits will demonstrate how high demands on precision and reproducibility can be met efficiently and economically.

The new all-electric EcoPrimus injection molding machine is ideal for the efficient production of mass-produced parts. A 24-cavity mold will be used at Swiss Plastics Expo. |
The all-electric EcoPrimus injection molding machine with 1000 kN clamping force has been specially developed to combine efficiency with high cost savings for standardized applications requiring only a small range of options. There will be no compromises in terms of easy operation. Like all other current injection molding machine models from the WITTMANN Group, the EcoPrimus comes equipped with the latest Unilog B8X machine control system.
This new machine is predestined for efficient manufacturing of mass products. During the Swiss Plastics Expo, an EcoPrimus 100/525 will produce closing caps for eyedrop bottles. For this purpose, a 24-cavity mold from HTW will be used. The parts will be removed by a W918 linear robot from WITTMANN, deposited on a conveyor belt and passed on directly to a tubular bag machine supplied by Ravizza Packaging to be packaged.
Micro injection molding with 3D-printed nanostructures
Structures measuring 0.04 x 0.04 x 0.1 mm and corner radii down to 0.005 mm – these are the requirements for a lab-on-a-chip application which will challenge a MicroPower injection molding machine at the WITTMANN booth.

At Swiss Plastics Expo, the MicroPower is equipped with the new WITTMANN W9VS2 robot. It fea-tures a full-fledged R9 robot control. |
The all-electric MicroPower machine specially developed for injection molding of extremely small micro parts is not only compact and energy-efficient, but also helps to save material. For the design of this machine makes it possible for the injection plunger to reach all the way down to the parting line of the mold. This reduces the melt cushion to a minimum, and the sprue is significantly reduced or even eliminated altogether. This structural specialty not only increases material efficiency, but also improves quality consistency, since pressure transmission is achieved via an extremely short flow path.
In just two square meters, the MicroPower machine concept combines a rotary table, auxiliaries, automation, temperature control unit, quality assurance, and other process units. A laminar flow box can be easily integrated for cleanroom applications.
The lab-on-a-chip devices will be produced on a MicroPower 15/10 from transparent PP. 3D-printed 2-cavity mold inserts from NanoVoxel inside a basic tool box from Ernst Wittner will be used.
The MicroPower will be equipped with the new WITTMANN robot model W9VS2. What is new: The Scara robot will now also be delivered with a full-fledged R9 robot control system. This offers users more scope for complex process sequences and enhanced integration into the B8X machine control system.
