By focusing on productivity, quality and energy efficiency, WINTEC – based in the Chinese city of Changzhou – is improving the performance of injection moulding machines for standard applications. At Plast Eurasia 2017, which is taking place in Istanbul, Turkey, from December 6 to 9, the subsidiary of Austria’s ENGEL Group is presenting a t-win injection moulding machine producing large-scale housing parts.
Since being launched on the market three years ago, the t-win series of hydraulic injection moulding machines has become strongly established in such fields as technical moulding, automotive and white goods. “Above all, our customers value the high manufacturing and product quality of our machines,” says Peter Auinger, President International Sales of WINTEC. The t-win machines are used for high-volume standard applications which, although not requiring special technology, nonetheless place high demands on quality and process stability. WINTEC machines are available in Asia as well as in further selected markets including Turkey, Iran, Egypt and South Africa.
Machine and robot from a single source
During Plast Eurasia, a t-win 4500-2000 injection moulding machine with clamping force of 4,500 kN is demonstrating the performance of the series. Large-scale housing parts with a shot weight of 430 grams are manufactured from polypropylene. A viper linear robot from ENGEL’s automation range removes the parts and places them on a conveyor belt. As a member of the ENGEL Group, WINTEC is in a position to deliver integrated manufacturing cells from a single source, with robots developed and produced in-house.
The C2 control unit for WINTEC injection moulding machines offers ample flexibility in terms of connecting robots of various types and brands. It is characterised by intuitive operation, which reduces the risk of operator error. The entire machine status is displayed on a clear-cut single screen. A quick adjustment page groups the most important setting parameters in a compact way. To ensure an ergonomic workflow, the 15" touchscreen can be swivelled out forward and is height adjustable. In terms of processing power, the C2 control unit outperforms control units of other machine producers in this area by more than 30 percent.
Fast dry cycles and sensitive mould protection

The t-win machines feature the servowin servohydraulic as standard. This allows a reduction in energy consumption of up to 60 percent and more in comparison with conventional hydraulic injection moulding machines. Other factors that ensure high energy efficiency include operating point optimisation and the dual-platen design of the clamping unit, with a reduced moving platen weight and frictionless movements due to zero contact between tie-bars and platen. The linear guidance of the movable mould mounting platen reduces friction and keeps the mould area free of lubricating oil.
The dual-platen clamping unit was developed in Europe and guarantees high platen parallelism throughout the machine’s service life, which results in sensitive mould protection, high dynamics and short dry cycle times. Parallel auxiliary movements are also optionally supported. The t-win injection moulding machines are available in six sizes with clamping forces of between 4,500 and 17,500 kN.
WINTEC was launched in 2014 with the aim of providing reliable, high quality and durable injection moulding machines for the manufacture of standard products. As a member of the ENGEL group of companies with headquarters in Schwertberg, Austria, WINTEC can draw on 70-plus years of mechanical engineering and application experience in injection moulding.
