Engel plans to display its new all-electric e-mac injection molding machine during Chinaplas 2013 (May 20-23; Guangzhou, China).
"The demand for compact, all-electric injection molding machines for components which need to have very precise dimensions is increasing," said Gero Willmeroth, head of sales and service at Engel Machinery in Shanghai. "The Engel e-mac helps us to meet these requirements in the best possible way."
During the four days of the fair, an Engel e-mac 50/50 will produce holders for semiconductor chips made of polyetherimide, an application that poses an extremely tough challenge in terms of the injection molding machine's precision, according to Engel. The holders measure 26 by 23 mm, with a wall thickness of just 0.65 mm and the mesh structure with an inner edge length of 0.42 mm. Despite these exacting requirements and the hard-to-handle raw material, the Engel e-mac achieves a cycle time of just 19 seconds in this application, the company said....
