Injection Moulding Asia Country Focus The cycle time is significantly lower than 3 minutes, although the preforms take around 30 minutes to cool. The cooling time can be controlled via the number of cooling positions in the external cooling station. System partners include Skymould (Ningbo/China), HRSflow (Hangzhou, China), Innolite (Aachen/ Germany), Opsira (Weingarten, Germany) and Gimatic (Shanghai, China). Meanwhile, Engel’s subsidiary Wintec builds its machines in Changzhou, China, tailored to the requirements of the standard market in Asia. It will showcase a t-win 10500-7000 hydraulic machine with a clamping force of 10,500 kN producing automotive interior door panels from PP. The shot weight is 650 g, and each cycle takes 30 seconds. Even in the standard version, the t-win machines are equipped with the servowin servo-hydraulics, reducing energy consumption by more than 60% compared to conventional hydraulic moulding machines. It will also show the all-electric e-win 1000-170 used to produce pump heads from fibre-glass filled PPS, which will be used in air conditioning systems in the car. KraussMaffei will show a GX 650-3400 with a clamping force of 6,500 kN demonstrating cascade injection with its repeat accuracy. A radiator grille is created in a cycle times of about 49 seconds. The connected FlexFlow hot runner control ensures a balanced cascade calibration. The result is premium quality components free of joint lines that can immediately be painted and galvanised, says the firm. The GX series has also been manufactured in Haiyan, China, since 2016.

known HYDRA MES from MPDV Mikrolab (MPDV) and is offered in three stages of expansion. In this way, the customer can decide how many MES functionalities are needed based on individual requirements. If the customer requires additional functions, the option is available to switch to HYDRA by MPDV. Aiming for the automotive sector Austria’s Engel will present a complex multicomponent process with interlinked injection moulding machines at Chinaplas. Two duo injection moulding machines will produce LED lenses made of PMMA with a thickness of 22 mm for vehicle headlamps. The lens base bodies will be produced on a duo 1060/400 injection moulding machine in a four-cavity mould. An easix articulated robot is integrated in the production cell and removes the four parts and passes them to an external cooling station. From there the robot takes four already sufficiently cooled preforms at a time and transfers them to the 4+4-cavity mould of the duo 600H/600H/500 combi multi-component machine with rotary table. There, two more PMMA layers are applied successively before easix removes the finished lenses.

Robotics domination eyed The automation of production is accelerating around the world: 74 robot units per 10,000 employees is the new average of global robot density in the manufacturing industries (2015: 66 units). By regions, the average robot density in Europe is 99 units, in the Americas 84 and in Asia 63 units. In China, automation is a key agenda in the Made in China 2025 roadmap. Factories may soon see an increased population of robots. According to Germanyheadquartered International Federation of Robotics (IFR), the robot density in China has accelerated significantly from 25 units in 2013 to 68 units in 2016, making China the 23rd in global robot density. It is in line with the government’s agenda to place China among the world’s top ten most intensively automated nations by 2020. During that period, the robot density is targeted to be pushed to 150 units; with sales of domestically produced industrial robots to total 100,000 units. The above mentioned companies, like Arburg, Wittmann, KraussMaffei and Engel, are contributing to the country’s yearning for automation with their robot offerings, too.
