WINTEC is celebrating its first appearance in America at NPE2018 from May 7th to 11th in Orlando, Florida, USA, with three injection molding machine exhibits. Starting in May, the subsidiary of ENGEL AUSTRIA based in Changzhou, China, will offer its hydraulic t-win and all-electric e-win injection molding machines in the USA, Canada, Mexico and Brazil.
WINTEC machines have been available in Asia since 2014. Tailored to the requirements of standard applications, WINTEC machines offer great productivity, energy efficiency and quality, a compact design and a solid, durable construction. The three exhibits at the booth W3303 exemplify how high quality can be combined with high cost-effectiveness to meet the requirements of a wide variety of industries.
t-win: high energy efficiency and sensitive mold protection
The hydraulic injection molding machines in the t-win series are available with clamping forces from 500 to 1900 US tons (450 to 1750 metric tons respectively), which makes them ideal for manufacturing large and three-dimensionally complex components. At NPE, a t-win 6500-3300 with a clamping force of 6500 kN will demonstrate the performance of this series by producing tensile bars for materials characterization testing in the automotive industry. Glass-fiber reinforced polypropylene with a shot weight of 250 grams per component will be processed; the cycle time is 40 seconds.
The t-win machines are equiped with servowin servo hydraulics as standard. This cuts energy consumption by more than 60 percent in comparison with conventional hydraulic injection molding machines. Other factors that contribute to the high energy efficiency include operating point optimization and the dual-platen design of the clamping unit with low moving masses and exposed tie-bars. The linear guidance of the moving mold mounting platen reduces friction and keeps the mold area free of lubricating oil. The dual-platen clamping unit guarantees maximum platen parallelism throughout the machine’s service life; this in turn results in sensitive mold protection, excellent dynamics and short dry cycle times. Parallel auxiliary movements, such as those of the ejectors, the core pulls or the nozzles are also optionally supported.
Equipped with the C2 control, WINTEC injection molding machines enable intuitive operation. The entire machine status is displayed clearly on a single screen. A quick adjustment page summarizes the most important setting parameters at a glance. In addition, the C2 control unit used in t-win machines offers great flexibility in terms of connecting robots of various types and brands. 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 t-win 6500-3300 at NPE is equipped with a viper 20 from ENGEL's linear robot series. The viper removes the parts from the mold and deposits them on a conveyor belt.
All-electric e-win for high precision and process stability
All movements performed by the injection molding machines in the e-win product line are servo-electric. The high-precision movements ensure stable processes and a consistently high component quality, which guarantees a fast return on investment. With its e-win series, WINTEC empowers processors to enter the field of all-electric injection molding technology without risk and follow the trend towards ever higher production quality. In addition, the machines reduce cycle times through the parallel movements of the drive axes and the outstanding acceleration of the injection axis, which can be up to 22 m/s². Low energy consumption and a compact design are further important efficiency features of the e-win machines. With clamping forces from 55 to 310 US tons (50 to 280 metric tons respectively), the machines are used in a wide range of applications.
Two WINTEC e-win machines will be running in booth W3303. An e-win 1000-310 with 1000 kN clamping force will be injecting speciman containers for medical diagnostics in a 2-cavity mold by Roembke Mfg. & Design (Ossian, IN, USA). At the same time, an e win 2800-940 with a clamping force of 2800 kN will be producing parts for medical clamps made of glass fiber reinforced polypropylene. GW Plastics (Bethel, VT, USA) is providing the 4-cavity mold. The two e-win injection molding machines are also equipped with ENGEL viper linear robots.
WINTEC injection molding machines are particularly popular for high-volume single-component injection molding, which does not require any special technologies, but nevertheless places high demands on quality and process consistency. The machines are delivered pre-configured, which guarantees short delivery times and fast start-up.
As a member of the ENGEL group with headquarters in Schwertberg, Austria, WINTEC can draw on 70-plus years of mechanical engineering experience.
