At CHINAPLAS 2019, WINTEC, a member of the ENGEL Group, highlights and showcases two machines that exhibit how high quality combines with the high efficiency. Customers can witness WINTEC’s product lines of a servo-hydraulic and an all-electric injection moulding machines which cover a broad spectrum of applications.
t-win: High energy efficiency and sensitive mould protection
The servo-hydraulic injection moulding machines of the t-win series are offered with clamping forces from 4,500 to 17,500 kN, which means they are particularly ideal to produce large or three-dimensionally complex components.
During CHINAPLAS, a t-win 13500-7000 injection moulding machine with a clamping force of 1350t impressively demonstrates the performance of the series by producing auto lamp housings made from polypropylene. The shot weight is 1,200 grams in a 2 cavity mold, while each cycle takes less than 70 seconds.
The t-win machines are equipped with the servowin servo-hydraulics as standard, which reduces energy consumption by more than 60% in comparison with conventional hydraulic injection moulding machines.
Other advantages that ensure a high degree of energy efficiency include operating point optimisation and the dual-platen design of the clamping unit with low moving masses and exposed tie-bars.
The dual-platen clamping unit was developed in Europe and guarantees precise mould guiding and maximum platen parallelism throughout the machine’s long service life, which leads to sensitive mould protection, outstanding dynamics and short dry cycle times. Parallel auxiliary movements such as the ejector, core pulls, or jets, are optional features.
The t-win 13500-7000 at CHINAPLAS is equipped with a viper 40 from ENGEL's linear robot series. The viper removes the finished parts from the mould and places them on the conveyor belt.
All-electric e-win for high precision and process stability
In the injection moulding machines of the e-win series, all machine movements are servo-electrical driven. The precision of movements ensures stable processes and a consistently high component quality, guaranteeing a fast return on investment.
The e-win series also allows for shorter cycle times. These are realized by the parallel movements of the drive axles as well as the breath-taking acceleration, up to 22 m/s2, of the injection axle.
Additional factors that contribute to efficiency are the low power consumption and the compact design. With clamping forces from 500 kN to 2,800 kN, the machines are used in a wide range of applications, where clean, high precision and quality processes are required.
At CHINAPLAS, an e-win 1000-170 with a clamping force of 100t is used to produce flip-top caps from polypropylene with a cycle time of 8.5 seconds.
Insights into intelligent manufacturing
As a member of the ENGEL Group, WINTEC is committed to the advanced concepts of the group. During CHINAPLAS, its exhibits operational data from the booth is transferred online and displayed in a manufacturing intelligence room in a remote location.
Via internet connection with real time machine data, WINTEC presents its leading concepts of future factory automation and Industry 4.0 readiness and demonstrates the benefits brought by digitization in manufacturing.
Rapid on-site service for high availability
WINTEC machines are designed and engineered in Europe and produced in China. Opened in 2014, the plant in Changzhou is tied into the global quality management of the ENGEL Group. Consequently, the same strict quality standards apply there as in all ENGEL plants worldwide.
In addition to quality, service performance is a decisive factor and affects the availability of the injection moulding machines. With a local dedicated service team and an in-house spare parts supply, WINTEC offers industry leading after sales support.
WINTEC’s Changzhou plant is currently being further expanded by doubling the manufacturing footprint to allow and cater for the steadily increased demand of their successful injection molding machines. The impressive construction works started end of 2018 and will be completed this year.
