Wittmann Introduces Three New Additions to Its Auxiliary Equipment Range

Wittmann has expanded its auxiliary equipment portfolio with three new product launches covering central materials handling, in-line recycling, and temperature control. All three systems focus on efficiency, ease of use, and long-term operating stability. They were previewed ahead of their appearance at the K Show 2025 in Düsseldorf in October.

M8 plus Network Control System for Central Material Handling

Wittmann has updated its network control platform for medium to large central materials handling installations. The new M8 plus system is designed to manage up to 320 conveyors, 64 dryers, and associated components such as blowers, filters, and valve stations. Up to eight complete material handling systems can be controlled from a single interface, giving processors a unified approach to planning and supervision.

Each device is networked and assigned a defined task. This enables tailored material supply strategies that match the requirements of individual production cells. The high-resolution touch screen provides a clear overview of the full system, along with detailed views of individual conveyors or dryers. Operators can view material routing at a plant level while still drilling down into specific components. The clear visualisation also helps with faster and more accurate material changes.

Material availability and audit compliance were priorities during development. Distribution is RFID coded to ensure traceability, and all data can be made available via OPC UA for wider system integration. Production cells connected through Wittmann 4.0 can be incorporated into the same control structure, which creates a cohesive environment for process monitoring.

A QR code on the interface connects users with AIM4Help, Wittmann’s AI-based support tool. This provides guidance for configuration queries and enables quicker fault-finding during maintenance or process adjustments.

S Max Primus Screenless Granulator for In-Line Recycling

The S Max Primus granulator has been developed for use beside the press use where energy savings, consistent regrind quality, and ease of cleaning are priorities. It is available in two sizes for integration next to injection moulding machines up to 150 and 400 tonnes, respectively. Both variants have compact footprints, which helps processors fit the unit within restricted cell layouts.

The granulator operates at a low rotor speed of 27 rpm at 50 Hz. This reduces energy consumption, noise output, and dust generation. Despite the low speed, it handles a broad range of engineering polymers, including styrenics, acrylate-based materials, and glass fibre reinforced compounds. The two sizes differ in cutting chamber dimensions, cutter configuration, and motor power, but both follow the same design philosophy.

The slow cutting action produces a uniform particle size that helps improve the proportion of good parts when the regrind is returned to the moulding process. A stable particle distribution also reduces the risk of feed irregularities. Long service life was another design target. The absence of a screen lowers wear and minimises the number of parts subject to replacement. The cutting chamber is fully accessible, so operators can complete cleaning and material changeovers quickly. This is particularly useful in plants with frequent colour changes or short production runs.

Low maintenance requirements and predictable regrind performance position the S Max Primus as a cost-efficient option for in-line recycling, especially for processors that rely heavily on reprocessed material to manage overall part costs.

Tempro basic 120 Temperature Controller for Large Consumers

Wittmann has expanded its Tempro basic range with a new model designed for applications that require high flow rates and accurate control at temperatures up to 120 degrees Celsius. The Tempro basic 120 is aimed at large consumers and applications where mould temperature stability is essential for repeatable part quality.

The unit is a single circuit controller fitted with a radial impeller pump. This enables high volume flow across a wide pressure window, which helps maintain stable mould conditions even when dealing with complex tool geometries or variable heat loads. The controller includes automatic filling with pressure monitoring and clear flow and return pressure indications.

A self-optimising microprocessor control system maintains temperature to within ±1 °C. This precision is further supported by a servo step motor-driven proportional valve within the cooling line. The valve responds to temperature fluctuations with finer resolution than previous designs, and its membrane-free construction reduces wear and extends service intervals. Operators can adjust the flow rate steplessly, which allows further refinement of mould conditions.

A colour 3.5-inch TFT LCD display is now standard across the Tempro basic series. The interface improves visibility and menu navigation compared with earlier seven-segment displays, allowing for quicker set-up and clearer status checks.

By improving regulation accuracy and reducing the energy input required for mould tempering, the Tempro basic 120 provides processors with a stable and economical option for high-throughput environments.

Summary

These three launches reflect Wittmann’s continued focus on practical design, clear operator interfaces, and operating efficiency. The M8 plus targets large-scale material handling, the S Max Primus delivers predictable regrind in in-line recycling, and the Tempro basic 120 supports stable mould temperature control for demanding applications. Together, they provide processors with new options for improving productivity and reducing resource consumption across a wide range of plastics manufacturing operations.
