High quality and efficiency for standard applications
By focusing on productivity, quality and energy efficiency, WINTEC in Changzhou, China is building injection moulding machines to meet the demands of standard applications. At K 2016, which takes place in Düsseldorf, Germany, from October 19th to 26th, the subsidiary of the ENGEL Group with headquarters in Austria will present itself to the international audience for the first time. The WINTEC machines are available in selected growth markets, particularly in Asia.
Since being launched on the market two years ago, the hydraulic injection moulding machines in the t-win series have become strongly established on Asian markets in such fields as automotive, domestic appliances and white goods. WINTEC machines are used for high-volume standard applications which, although not requiring specialist technology, nonetheless place high demands on quality and process stability.
At K 2016, a t-win 6500-3300 injection moulding machine with clamping force of 6,500 kN will demonstrate the performance of the series. Fibre reinforced polypropylene engine covers with a shot weight of 800 grams will be produced in a single-cavity mould supplied by a customer. An ENGEL viper 20 robot will remove the components throughout the eight days of the trade event.
The C2 control unit for WINTEC injection moulding machines offers ample flexibility in terms of connecting robots of various types and brands. The C2 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 33 percent.
Fast dry cycle times and sensitive mould protection
The t-win machines are fitted with a servowin servohydraulic as standard. This cuts energy consumption by more than 60 percent compared to standard hydraulic injection moulding machines. Other factors that ensure the extremely high energy efficiency of t-win machines 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 moving 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 maximum platen parallelism throughout the machine’s service life, which results in sensitive mould protection, excellent dynamics and short dry cycle times. Parallel auxiliary movements, such as core pull, ejector or nozzle 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 established in 2014 to build high quality, reliable and durable injection moulding machines for the manufacture of standard products in large quantities. As a member of the ENGEL corporate group, WINTEC can draw on 70-plus years of mechanical engineering experience. ENGEL is the world’s largest producer of injection moulding machines and a leader in energy-efficient drive technology.

Large quantities of the engine covers are needed. Although these are not particularly sophisticated technologically, high precision is necessary. In this case the t-win injection moulding machine promises a high-performance, reliable and cost-effective solution.
