High-tech machines and processes at the Chinaplas in Shanghai

WITTMANN automation and peripheral equipment

In addition to the robots and peripheral appliances integrated in the injection molding machines, WITTMANN BATTENFELD will present a wide range of robots and peripherals at the Chinaplas as stand-alone solutions. The products on display will come from the production plant in Kunshan.

In the area of automation, robots for smaller-sized injection molding machines will be showcased, such as the models W808, W818TS and a PRIMUS 16S. Short removal times are extremely relevant, in particular for applications in the clamping force range of up to 300 t. For these applications, the robots mentioned above qualify primarily by small moving loads and high dynamism. To achieve this, the robots are equipped with a ribbed aluminum profile and belt drive in the vertical axis. WITTMANN is presenting this technology as a “single-axis” on the W808 and PRIMUS 16, and in telescopic form on the W818TS robot.

Moreover, the W828 und W838T - also 100 % locally manufactured – will be on show. These models feature load capacities of 12 kg and 15 kg respectively. To a certain extent, the W838T stands out from the rest, since it is the first Asian appliance to take up the design language of the European WITTMANN pro series. In this way, the manufacturers have managed to increase the robot’s rigidity and offer their customers a compact, high-performance appliance for parts removal. This is also reflected in the pneumatic, pivoting C axis, which is built in as standard and has twice the torque of the W828 robot.

In the area of temperature controllers, three models of the entry-level priced TEMPRO basic C series will be exhibited, namely a TEMPRO basic C90, a TEMPRO basic C140 and a TEMPRO basic C120M. The first two are indirectly cooled, single-circuit temperature controllers with top temperature limits of 90 and 140°C respectively, and a standard heating capacity of 9 kW. The TEMPRO basic C120M is an appliance with direct cooling and extremely compact dimensions. It features a heating performance of up to 18 kW. Also on display will be a single-circuit and a dual-circuit model of the powerful TEMPRO plus D series, that is a TEMPRO plus D180 and a TEMPRO plus D160. The TEMPRO plus D appliances can be operated easily and intuitively via a touch display. Numerous options make it possible to configure these appliances for virtually all existing applications in plastics processing.

The WITTMANN flow controller will also be present at the Chinaplas. The new FLOWCON plus will be shown, now also available as a stand-alone model, a compact, fully automatic medium distributor, which can be placed close to the mold and enables parallel distribution of the entire flow volume to the individual temperature control channels. In this way, the total pressure loss can be reduced, and it is possible to regulate and monitor the flow quantity or return flow temperature for every individual temperature control circuit. The new FLOWCON master box, which comes with the appliance, provides the stand-alone model with a graphic operating system. It also houses the power connection.

In addition, WITTMANN will showcase two ATON segmented wheel dryers at the Chinaplas. The segmented wheel of this dryer model consists of numerous chambers containing a loose fill of desiccant balls. In combination with the innovative 3-save process, this enables optimal energy utilization as well as a continuous drying process with a consistent low dew point. An ATON with an integrated dry air system will be shown, which is specially recommended for transparent or optical parts. After drying, the material does not come into contact again with the ambient air and moisture, which prevents inclusions in the end product.
