Chinaplas: Wintec expands injection machine production capacity to Chi


Engel Group brand Wintec invests 12 million euros in expansion of its production facility in Changzhou, China, as it sees shipments of injection machines to global white goods manufacturers increase dramatically . The new production capacity will be in place in the fourth quarter of 2019.

Wintec ‘Feltes: The quality of injection machines made in China is recognized around the world.

According to Michael Feltes, president of sales and service, Engel Machinery (Changzhou) Co., Ltd., [appliance manufacturers] with production operations in China, South Korea, Mexico and the United States, are purchasing Wintec machines in increasing volumes. “They recognize our quality and reliable equipment, able to operate 24/7, year after year. They started with small quantities 2-3 years ago and are now buying in increasing numbers. Feltes adds: “Wintec machines are known for their very high repeatability and their lifespan of 15 to 20 years if maintenance is carried out properly.

At Chinaplas 2019 from May 21 to 24 in Guangzhou, China, will present two injection machines combining quality and efficiency (hall 4.1, booth J41). Visitors can admire Wintec’s servo-hydraulic and all-electric injection molding machines which can cover a wide range of applications.

Focusing on productivity, quality and energy efficiency, the company builds injection molding machines in Changzhou, China, designed to best meet the requirements of standard plastics applications in automotive, white goods , technical molding and other industries. Wintec machines are preferably used for high volume one-component injection molding, which may not require any special technology, but still places high demands on quality and process consistency. With one servo-hydraulic machine and one all-electric machine, Wintec will market itself as a provider of advanced and reliable injection molding solutions.

The servo-hydraulic t-win series injection molding machines are offered with clamping forces of 4,500 to 17,500 kN, which means they are particularly ideal for producing large or complex three-dimensional parts. During Chinaplas, a t-win 13,500-7000 injection molding machine with a clamping force of 1350 tons, which would be the largest on display at Chinaplas, will demonstrate the production of polypropylene automotive lamp housings. The shot weight is 1200 grams in a two cavity mold, while each cycle takes less than 70 seconds.

Other advantages that ensure a high degree of energy efficiency include the optimization of the operating point and the double plate design of the clamping unit with low moving masses and visible tie rods. The linear guide of the movable mold assembly plate allows smooth movements as well as clean production without lubricating oil at a high level of availability.

The dual platen clamping unit was developed in Europe and guarantees precise mold guidance and maximum platen parallelism throughout the long life of the machine, which leads to sensitive mold protection, exceptional dynamics and short drying cycle times. Parallel auxiliary movements such as ejector, core pulls or jets are optional features.

The C2 control used in all Wintec machines features an intuitive interface optimized for operator guidance which reduces the risk of operator errors. The complete machine status is displayed clearly on a single adjustable display which guarantees an ergonomic workflow. A quick setting page summarizes the most important setting parameters in a compact way.

In addition, the C2 offers great flexibility to connect robots of different types and brands. As a 100% owned brand by Engel, Wintec can provide integrated manufacturing cells from a single source, with robots developed and produced in-house. Chinaplas t-win 13500-7000 is equipped with a viper 40 from Engel’s linear robot series. The viper removes the finished parts from the mold and places them on the conveyor belt.

With its e-win all-electric machine series, Wintec enables transformers to enter the world of all-electric injection molding with minimal risk and follow the trend towards even higher production quality and complex applications. The e-win series also enables shorter cycle times. These are achieved by the parallel movements of the drive axles as well as by the breathtaking acceleration, up to 22 m / s², of the injection axle.

Additional factors that contribute to efficiency are low power consumption and compact design. With clamping forces of 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 100 tons will be used to produce polypropylene flip-top caps with a cycle time of 8.5 seconds. The hinged lids are closed during demoulding, which means that a no post-processing procedure is required.

The t-win and e-win machines feature high productivity and energy efficiency, advanced compact design and long service life. They are delivered preconfigured, which guarantees short delivery times and quick commissioning.

During Chinaplas, operational data from Wintec’s exhibitions will be transferred online from the booth and displayed in a manufacturing intelligence room in a remote location. Via an internet connection with real-time machine data, Wintec will present its concepts of future factory automation and Industry 4.0 readiness and demonstrate the benefits of digitalization in manufacturing.
