Engel: Plastics für Electronic Industries - Meeting in Mexico

In line with the slogan, "Smart Ideas for Smart Phones and More" Engel has invited plastics manufacturers in the telecommunications and consumer electronics industries to Mexico for its Teletronics Days on 11 and 12 May. At its subsidiary in Querétaro will be demonstrating in common with the technology partner Roctool the efficient production of thin-walled components with a high-quality finish.

"Mexico is a key market for the telecommunications and consumer electronics industry," stresses Heinz Rasinger, Head of the Teletronics Business Unit at Engel in Schwertberg, Austria. The international supply industry benefits from this, in particular companies in the USA and Far East - including renowned TV manufacturers - who have relocated to or established production capacities in Mexico over the past years. In the last five years the Mexican injection moulding machine manufacturer and automation expert generated sales of over 50 million Euro in the teletronics segment alone. "The demand is predominantly for system solutions for displays together with thin-wall applications for high-quality finishes," says Rasinger.

Inductive mould temperature control for high quality
One of the highlights of the event will be inductive mould temperature control, which produces mirror or matte finishes without weld lines. The technology - developed by Roctool and optimised together with partners - employs electromagnetic fields to bring the mould surface particularly quickly up to the desired temperature. This enables a variothermal injection moulding process, which guarantees complete mould filling and precision machining.

The second highlight will be the manufacture of housing parts with lectures on production technologies and a demonstration of the manufacture of thin-walled, foil-decorated laptop casings using embossing technology.

Efficient integrated system solutions
The potential of the induction process will be demonstrated on a fully electric injection moulding machine with a clamping force of 1.000 kN. It will be used to manufacture mobile phone shells by thin-wall process with a particularly high-quality finish at visible points. A robot will remove the mobile phone shells from the mould. Integrated sys-tem solutions allow providing a perfect mesh between injection moulding machine and automation, process technology and mould project engineering, thus ensuring a high level of process security and efficiency.

During the event the PDA shells will be manufactured from PA 6 with a glass fibre content of 50 %. The induction process ensures a par-ticularly high-quality finish.
